Someone asked this [0] at the end of last year and I found it really useful for gift ideas. Figured it was worth another go!

CO2 Monitor to let me know when I need to let some new air into my office. Mine is a TFA Dostmann 31.5009, but any model with an NDIR sensor should be fine, there are many choices around 70-150 EUR.


CO2 poisoning is very common. It leads to fatigue, headaches/migranes and concentration issues. Most people don't recognize it and try to cope with caffeine & pain killers.

I noticed that sitting in a tightly closed office surrounded by monitors , CO2 was being trapped around me . I started testing with blood oxygen monitor and could reliably predict low blood O2 based on the above symptoms.

tl;dr keep your door and/or windows open and use a fan to circulate air into your desk area. It's very easy to reach high CO2 concentrations in a small room when you are surrounded closely with monitors (flat surfaces)


It's important to note these two issues (high CO2 and low oxygen) only go together in the most extreme scenarios and CO2 can be impactful long before O2 levels noticeably decrease or start affecting your blood O2 levels. For CO2 to be extremely high and causing headaches, dizziness, and nausea it's around 0.1% to 0.2% (more often represented as 1,000 to 2,000 ppm due to the low typical concentration of ~420 ppm globally). On the other hand, air is 21% oxygen (by volume) and at 10x the difference above different (so 1%) less it's not even considered oxygen deficient yet.

While I'm writing the comment, it's important to note you will almost certainly notice high CO2 content but you very likely won't notice low O2 content. Think about inhaling a helium from the balloon tank. You know there is very little O2 in it at all, you can even hear how it changes your voice, but you can keep breathing more in and out until you pass out cold and not even "sense" the lack of O2 until seconds before you pass out you start feeling very lightheaded. On the other hand if you breathed in CO2 like that you'd immediately notice and feel awful. This is because the body doesn't detect how much O2 you're taking in it detects how much CO2 you're able to get rid of. All this is to say, if you have low blood O2 levels don't necessarily expect to be aware of it.

The third thing I'll mention, since it seems inevitably someone comes by and reads "CO2" and confuses it with CO (carbon monoxide), is CO and CO2 are different things with different ppm values and different outcomes. It seems inevitably in the conversations CO will kill you in less than an hour at 1000 ppm, with effects from long term exposure possible at far less than that. If you have an appliance that burns fuel to function you really should have CO detectors, even if your state doesn't mandate one. If you don't get a CO2 monitor the worst that'll happen to you is you'll not feel as great (assuming CO2 isn't so bad your problem is actually there isn't enough oxygen left).


I just noticed this got pretty chopped up saving between a couple edits so here is a cleaner version if anyone needs it:

It's important to note these two issues (high CO2 and low oxygen) only go together in the most extreme scenarios.

For CO2 to be extremely high (causing headaches, dizziness, and nausea) it only needs to be in concentrations around 0.1% to 0.2%, more often represented as 1,000 to 2,000 ppm due to the low typical concentration of ~420 ppm globally. On the other hand, air is 21% oxygen (by volume) and at 10x the difference of 1%/10,000 ppm less than normal the air is not even considered oxygen deficient yet.

While I'm writing this comment, it's important to note you will almost certainly notice high CO2 content in your environment but you very likely won't notice low O2 content until it's well too late. Think about inhaling a helium from the balloon tank. You know there is very little O2 in it at all, you can even hear how it changes your voice due to the displacement, but you can keep breathing more in and out until you pass out cold and not even "sense" the lack of O2 until seconds before that moment when you feel lightheaded or your vision starts to fade. On the other hand if you breathed in CO2 like that you'd immediately notice and feel absolutely awful. This is because the body doesn't detect how much O2 you're taking in it detects how much CO2 you're able to get rid of. All this is to say, if you have low blood O2 levels don't necessarily expect to be aware of it.

The third thing I'll mention, since it seems to inevitably come up, is "CO2" (carbon dioxide) should not be confused with "CO" (carbon monoxide). CO and CO2 are very different things with different ppm values of concern and different outcomes when they are out of range. CO will kill you in less than an hour at 1000 ppm with effects from long term exposure possible at far less than that. If you have an appliance that burns fuel to function you really should have CO detectors, even if your state/goverment doesn't mandate one. If you don't get a CO2 monitor the worst that'll happen to you is you'll not feel as great (assuming CO2 isn't so bad your problem is actually there isn't enough oxygen left).


Can you summarize your point?


Keeping door and windows open while it's very cold or very hot outside can lead to extremely high heating/air conditioning bills. Meanwhile, high quality energy recovery ventilators that can exchange air with the outside without ruining your insulation tend to be a lot more than $200.


cracking everything wide open for 5 minutes doesn't have too bad of an effect on temperature in my experience, and gives you good air for a few hours.


My home has very poor ventilation so I periodically will open the windows and blast a box fan to "flush" the dirty air out. If done quickly, there's not much thermal loss.


It really depends on the house, if you have low thermal mass home then airing it out would definitely lead to a substantial thermal loss.


I meant the door to your office.


Although a bit above $200, but I own an Aranet4 CO2 monitor (it also measures humidity, air pressure, and temperature). It has a great app that allows you to see historical data too.

I've been using it for a while already and I'm really happy with it.


It's on sale right now at $149, I just bought it thanks to your comment!


I've been wanting to get a CO2 sensor for a while now, but I want one that interfaces with Homebridge or directly with Homekit. I'd appreciate any recommendations!


Mila has it built in and the added benefit of being an air filter. Works with Homekit and can alert you.


That looks really nice, but seems a bit overkill for my use case.


SCD30, your microcontroller of choice and your own code.

I have CO2 measurement working with an old third party 3.3v Arduino clone, and a nice 4-digit 7seg amber display.


Does this actually do anything for your perceived wellbeing?


Hands down my choice is the Pinecil soldering iron: https://pine64.com/product/pinecil-smart-mini-portable-solde...

It's less than $50, it runs FOSS (IronOS) so you own it, and it can be powered by USB or by via a barrel jack so it's ding dang handy.


Why does a soldering iron need an OS? I read the product page and I think I’m still missing something.


IronOS is actually a firmware, not a classical operating system. The soldering iron is like many modern appliances a smart device and contains a RISC-V CPU on which the firmware runs. I bought a Pinecil as well this year, and it's really a great tool, and I dare say much more versatile and powerful than many traditional soldering stations which cost much more.


I got the older TS100, for which IronOS was created originally, and it makes such a difference compared to a "dumb" soldering iron. I'm not very skilled in soldering, but the tool makes up for a lot of that.

Nevertheless, I would never have thought that I'd ever own a soldering iron requiring firmware.


I still don’t get it.

My soldering iron is a hot piece of metal with a plastic handle. It works. What am I missing out on?


Getting hot has a lot of complexity, actually: How hot does it get? How can you select the temperature and how accurate is that selection? How well does it maintain the selected temperature?

Simple soldering irons often don't even have temperature selection. And their predetermined temperature drops significantly when heat is transferred into the soldering pieces.

I can dial the Pinecil very accurately to anywhere between 100° C and 400° C, to provide the optimal temperature for the soldering job and it meticulously maintains that temperature (given the power supply is beefy enough).

Another nice feature is automatic stand-by when the tool isn't used. This preserves the tip, saves energy and lowers the risk of accidentally setting anything on fire. It automatically heats up blazingly fast when I pick it up again.


Pretty much this. Abridged for my little knowledge: I can easily set up my favorite temperature, and I can be sure that it's constant no matter how big the part I'm soldering. As a bonus, the soldering iron cools down when I'm not using it, making accidental touches less painful. Another bonus: there's a "boost" button for very stubborn solder joints.


Got it, thanks! That makes way more sense to me.


I’m sorry but I still don’t get it either. If it’s hot enough, you’ll know it’s ready when it starts melting whatever you use to solder. Why would one need anything more?


As a general rule, anything that uses electricity to get hot is going to need to run a PID if you want it to maintain a stable temperature. Once you've got the microcontroller in there it's trivial to add nice little features like thermal runaway detection or auto cooling/auto heating when the iron is put down/picked up, which are a couple of things the pinecil does.


Most likely a RTOS, not a real OS.


The link you provide states "Device Warranty: 30 Days". This is ridiculously short. Is this thing at all reliable? If yes then why such a "non-warranty"?


The Wera Toolcheck Plus has been a great addition to my toolbox

Generally now grab it first, when a job comes up!

https://products.wera.de/en/ratchets_and_accessories_zyklop_...


A toolset for a mechanic with an on-the-go lifestyle. Great to take to the local pick-n-pull.


I have a different ratchet set from Wera, which is also really nice and handy. Wera generally makes excellent tools, especially for the price point. My only gripe is that the printed-on size information on the handles of their screwdrivers wears off quickly, which is especially annoying for Torx drivers.


How do you buy it? Want to grab one for my brother, but there's no purchase button? Weird


look at a local distributor, thats just the productpage.


Bought it on Amazon


Damn that's nice. If you don't need the sockets the Icon mini ratchet set works well for $39 and it also has a flexhead.


Plus one. Great tool set for the price.


Great product I recommend as well


A shavette/straight razor blade: even after deciding on going 100% bald I still love cutting my own stuff, so I decided to go down the rabbit hole of self beard cutting. Never had more fun, outlining my beard has become one of my favourite pastimes ever. And I can have my beard on point whenever I need to, at no cost. Paid ~20€ for the blade holder, and ~8€ for 400 blades. (Bonus addition: hair clipper. Just make sure you buy one that has a lever and enough RPM)

Audiophile IEMs: there's a lot of stuff under the 200€ mark that can make your ears feel previously undiscovered levels of joy. And if you're listening to music a lot of time, this is a damn good investment. Truthear and Moondrop have a lot of interesting affordable options.

Acoustic panels: if you play music on speakers a lot, getting your room to sound drier can really make you discover new levels of detail. Just don't buy the cheapest polyuretane ones, as they only cause random dips in mid freqs.

Smart watch/band: Nothing too fancy, just anything that can notify me of stuff so I can keep my phone away and avoid picking it up to read a simple text message.


I haven't gone as far as a straight razor, but I've just in the last few weeks switched to a DE razor coming from years of using cartridge razors with too many too closely spaced blades that clog then degrade and cause irritation.

I'm trying a Rockwell 6C (around $60) with its interchangeable base-plates for different aggressiveness on blade exposure/angle, and just started on a variety pack of blades to see what suits me - so far so good on the experiment, it's at very least not causing any more irritation and produces less waste. Shaving accessories _is_ a ridiculous rabbit hole of hipster consumerism, but doing better-than-default seems like it might be worthwhile.

Right now it's just for face, by my hair is rapidly approaching "Doonesbury's Old Surfer Dude" so the role might expand.

Or full sized cans - Sennheiser HD598 can be found for ~$100 and you get fantastic sound out of basically everything, beating many $400+ bullshit headphones


I too have the HD598, great open headphones: you can hear environment noises perfectly well, and they sound great. When I need some insulation, I use the Audio-Technical ATH-M40X. Also sounding great, quite faithful, like the HD598. The price is similar.


um, but these are actually $400 cans...


Not really? Hard to find new though, 598 is older model, 599 is almost the same and more available

https://www.amazon.com/_/dp/B01L1IICR2/ - HD599 new, $149

https://www.amazon.es/_/dp/B01L1IICR2/ - HD599 new, €115

https://www.amazon.es/dp/B07Q7S7247 - HD599 new, €101

https://www.ebay.com/itm/296053418289 - HD598 used, $88


OK, if the 599 is the same. I simply googled, and found this for hd598: https://www.amazon.com/Sennheiser-HD-598-Over-Ear-Headphones...


A sous vide machine. It's just a fancy stick that circulates water at a precise temperature, but it makes the most delicious and tender chicken and fish that you'll ever make at home. You can start it in the morning and leave it going while you're out. Then dump the contents into a frying pan for a minute or two to sear the outside, and lunch/dinner is ready.

You do need a vacuum sealer, but the total investment is less than $150, which you can easily recoup when you find that you don't crave restaurant or takeout food as much as you used to.


> You do need a vacuum sealer,

No, you don't, zip-top bags with the excess air pushed out by water pressure and sealing after most of the bag is submerged work quite well.


Yes, it can be done. That's what I did for this year's Thanksgiving turkey.

My workflow these days is to buy a bunch of meat from Costco, then repackage it into portions with seasoning and throw it all in the freezer for later. In that case, removing all the air helps not just with buoyancy, but also with freezer burn.


mmm, delicious zip lock plastic cooked to perfection.


You don't cook at temperatures where this is a problem.


As opposed to the same plastic vacuum sealed and heated the same way?


Been considering buying one but I am worried if plastic staying in contact with food while hot. Is this something you researched?


America's Test Kitchen looked into it and it's just not a problem at the temperatures used in sous vide.

There are no issues in terms of taste or plastic leaching or anything of the sort, though if you're really paranoid you can always use Mason jars or silicon bags.


I use reusable food grade silicone bags I bought from Amazon. They are not vacuum sealed but I don't think that matters at all. As long as the portion of the bag containing the food is completely submerged the water pressure is sufficient to seal the bag around the food and ensure even heating in my experience.


I did not research it. The hottest temperature I use is 145F for chicken or pork ribs. Salmon is only 109F. If you have already looked into the use of plastic when cooking, which I haven't, and you know which temperature range is considered dangerous, then those numbers might help you.


how do you deal with seeping your proteins in plastic next to hot water?


See response to sibling comment. I haven't considered it.


Noise canceling wireless earbuds. I’ve had both a Jabra and a Beats… very happy with both. Nice for blocking out noise. No messy cables, can use with any device…

I was skeptical, I liked my corded headphones fine. Just turns out these sound better and are way more useful for me.


I've had noise canceling headphones for a while now, and I love using them in flights, but somehow I could never get to use it all the time to focus like some of my friends do. I am definitely not an expert in this area, and I have no evidence to argue for this, but somehow it feels like actively producing sounds to cancel out the noise and blasting it into your ear all day (i.e., when noise cancellation is on) can't be good.


Theoretically the sounds they produce cancel out the noise before either sound wave reaches your ear. I know some people experience some discomfort due to pressure changes, but the volume of the noise cancellation shouldn't be an issue by itself.


For people who dislike the "plugs", I can recommend Huawei FreeBuds (base version, not Pro). They are open design, very comfortable to wear for long periods. They have ANC, due to open design, it's not perfect, but still quite noticeable.


A Steelcase Leap V2, $150 (and 90 minute round trip pickup) using Facebook Marketplace. I probably got a little bit lucky, but it is definitely worth checking for things like this.

Also, a shout out to my friend who let me try his for 30 minutes since I couldn’t in a store.


I have a Leap V2 too from 2021 ($300 used). Best chair ever. So glad I got this instead of the much cooler looking Herman Miller Aeron -- the Aeron is amazing, but the Leap is more adjustable and has a more comfortable fabric seat.


Got a Leap from a user office furniture warehouse. Great buy for sure. Look up in your area there’s probably one too. They are usually in an industrial area somewhere. Just a giant warehouse with used office furniture.


$150 for a Leap v2 is an incredible deal. Great chair, I used mine for many years.


A KVM switch with HDMI and USB, makes switching from personal and work computer so much easier


I have one of these in my home office. Just press a button to switch from my work laptop to my PC, including all peripherals like speakers, webcam, mic, etc. My only complaint is that the audio behaves a little strangely. It buzzes and pops loudly when switching and during startup, and I’ve had to customize my audio configuration to account for some of the quirks, but it’s painless at this point.

This is the one I use https://www.avaccess.com/products/4ksw21-dm/


Do you know of any that support HDMI 2.1 properly for 8K 60 Hz monitors? I currently just have a USB switch and two HDMI 2.1 cables, and manually change the input on the screen each time.


Don't do that, do this: https://haim.dev/posts/2020-07-28-dual-monitor-kvm/ - free and works great!



I have the Aten CS1944DP, a dual screen, 4K60 DisplayPort KVM with the ability to drive 4 computers. I use two 27” 1440p144 monitors.

Cable management is a bit of mess, but it’s fantastic to be able to switch between personal, work, client and something else computers with the flick of a button (or keyboard shortcut).

I’ve not heard or seen any 8K KVM.


I've thought about these but don't want to mistakenly type something crazy meant for my friend groupchat into my work computer.


https://shokz.com/products/opencomm2

I am on conf calls and video chats for several hours per day. These are a product I would pay for until I die.


My mom got me a pair of AfterShokz (the former name of this brand) years ago, and I’ve been hooked ever since. I’m on my third pair now, and I’m pretty brutal on them. I wear them every day for long periods, and I really enjoy having headphones that don’t make me feel cut off from everyone around me, but still let me listen to podcasts that might not be kid-appropriate while I’m doing work around the house. They’ve dramatically improved for listening to music over the years, but I swap them out with dedicated IEMs for that most of the time. I also have a pair of over-ear headphones at my desk when I really need to tune out distractions.


I have their OpenRun headset, and for voice the quality is great; music a little iffy but acceptable when considering not getting hit by a car. Battery is awesome, and I'm assuming thats the same for the Opencomm


Yes, I get almost a full day of talk time out of a charge.


What’s the biggest improvement in your experience versus a more traditional setup? (Either over-ear with standalone mic or in-ear buds etc). Never tried bone conduction!


Mitigates further hearing loss from years of using buds. Also, when in a loud or crowded environment, I just put my fingers in my ears and can hear the other party crystal clear (vs potentially turning the volume up on buds to dangerous levels to compensate).


Oh now that is something I never considered! Interesting idea. Might have to give this a shot at some point.


I have a pair of AirPods Pro 2 and I would say I get the same benefits plus more.

They do cost more than this product though.


But... those go in your ear. These don't.


Yes but that’s just mode of wearing. The AirPods Pro 2 deliver the same benefits nonetheless.


Fountain Pen: https://cultpens.com/products/twsbi-eco-fountain-pen-white

Makes writing a lot more enjoyable for me


The thing that I really like about fountain pens is that you can get a WAY finer line with one than you can with other pens. My favorite is the Pilot Kaküno, which is actually pretty damn cheap (in the ballpark of $15) but if you get the version with the extra fine nib it gives you (surprise surprise) a really fine line. I personally like it more than the more expensive pens I tried out, but I also never waded all that deep into the expensive end of the product pool. Spending more than $50 on a pen would shrivel my soul to ashes.

I can’t find it on Pilot’s website (hope they haven’t discontinued it), but it’s available on Amazon, etc.

Obligatory caveat: pen enjoyability is pretty subjective. I put a lot of value on stuff like how it feels when I’m writing and a fine line (so I can write tiny in margins, and just because it looks cool IMO), but your mileage may vary substantially.


That's a nice fountain pen. I thought about getting one, too.


Gyroscopic Screwdriver

My brother in law in a general contractor and raved about his new gyroscopic screwdriver a couple years ago. I bought one last month and it's easily the best thing I've bought this year. Under $100 and it's truly a must have. I have the dewalt one, not sure if any other brands make em.

https://www.amazon.com/DEWALT-DCF682N1-Gyroscopic-Inline-Scr...


I bought a Bosch GO this year, my brother as well. Should be the same kind of tool. It drives the screw in (or out) if you apply pressure to it.


I just took a look at the Bosch. It looks like you have to switch a button to screw or unscrew. The Dewalt, you twist counterclockwise and it unscrews, clockwise and drives the screw in. You don't have to manually switch directions. The coolest part is the more you twist the screwdriver, the faster it will turn. You really have to use it to feel how awesome of a device it is.


Yeah, there's a switch to select direction. But it activates by pressure. I'm either screwing a bunch of screws in or out, so it's not a big hassle to use the switch when you need the other.

And this thing generates so much torque, I feel kinda worried about twisting my wrist to select the direction.


This is more of request for recommendation for sleep headphones.

https://www.meeaudio.com/M6G2

I bought a dozen of above headphones for sleep, cheap low profile that is very comfortable to sleep in. Lays flat, no hot pressure points. Only issue is they're wired, and josling in bed means every few months I kill one from wrecking their cabling/connector. They had a cheaper discontinued bluetooth version of the buds I was using prior, but battery levels dropped to less than 8 hours and the battery warning (alarm) plays at 200% volume. I see Mee has a few higher end buds with bluetooth adapter for $80+, but they're still wired behind neck format with proprietary connector that would be cost prohibitive replace to frequently, especially if UI sounds still offensively loud.

Wondering if anyone knows a cheap chifi buds with same form factor that can be paired cheap bluetooth adapter that has quiet UI sounds. I've done a few rounds of searching and have came up empty.


+1 for cheap wired sleep headphones! Changed my life listing to brown noise with no worries about battery life.

Also the manta sleep mask


A 96-sheet notebook + a Pentel needle-point pen. I've been feeling some strong headaches lately and the doctor's requested me to stay away from screens as much as possible. I've been using the notebook and this cheap yet nice pen to write down ideas and whatever. It's been a month now and the changes in terms of creativity and mental clarity are quite noticeable.

Aster (https://www.ibik.ru/)

Surprisingly functional multiseat for windows. Lifetime license 50-100 for 2 seats depending on region. Partner's computer went kaput, and used this + steamlink to turn monitor into another computer. I see people online using this to play two seperate games on different "seats". Was planning to get seperate media centre PC, but this worked so well I ended up using money to upgrade PC components. Yeah, it's Russian software, but there's reddit posts dating back a few years. I can see how software/hardware vendors don't like multiseat since less sales, but I see a lot of sense in pooling budget for one extra powerful system instead of buying multiple compute devices. I wish Windows had native functionality.

Edit: Upon search, I am surprised Aster has been mentioned only one other time, 6 years ago in all of HN. Only 4 pages worth of multiseat comment dating back 13 years.


Doesn't this violate most Windows Licenses? Windows simultaneous multiuser support on all NT-based OSes but it was normally disabled by policy unless you paid for the Server license. This is why Windows RDP normally locks the local desktop when you connect remotely rather than spawning a parallel session. I remember there were some US-based startups doing this but they ran into legal issues once they got past a certain point.

This company appears to be Russian so they can ignore the legal issues, but it would be bad to use this in a situation where MS might want to enforce their license.


I have no idea. General consensus from what I read is it's Russian, and very hacky, but works great. Even on Windows Home, no need Pro, or virtualization route where you have to split core/resources. They seem to primarily sell to developing countries, especially computer labs where I presume Microsoft don't care, or fine with people pirating if it means using Windows.


Wow, I remember using this back when I was a poor high school student trying to share my GPU with my younger brother. I don't think I was able to get it working reliably though.

Multiseat in general is just super niche. I wish it took off more and maybe it would have turned into an officially supported solution.


>Multiseat in general is just super niche

That's what I thought, but I think compute/cores + gpu power + wireless networking these days makes solid case for multiseat. Instead of buying another media center computer, I have a faster main computer with better CPU + GPU, better home wireless networking to beam that capability anywhere in the house. Previously I already remote desktopped into my main computer via different screens around the house, but now my partner can do it while I'm using said computer as well. The extra money in main computer = I'm gaming at 1440p vs 1080p or rendering with 20+ threads instead of 12, while partner do their low impact media/browsing for less cost. At the point, instead of partner upgrading their PC, it's starting to look sensible to split into 3 seats, 1 for me, 1 for media centre, 1 extra for partner. Perhaps spend a few 100 on dedicated GPU for new seat instead of 1000+ on seperate system.


It is a shame Windows gates this behind their business edition(s) as it could really cut down on waste, especially now that streaming is becoming practical.

I recall trying this with Linux and it worked reasonably well.


Yes I can see this previously being limited and setup specific if it means being confined to wires/same room, but with decent wireless, people are running this with cheap headless client like Pi+Moonlight or Steamlink on monitors in another room. Even a few years ago I had to run a network cable to my steamlink. But now it's streaming at 1080p60 with very little latency and frame loss. But so far, diverting $$$ to have a faster computer with more cores, and better GPU, and faster wireless networking, and a faster media centre than I would have otherwise cobbled together has been win-win-win.


I'll add my own: prescription sunglasses. Game changer.


Yes. They are great for driving. My vision plan has an annual allowance and I had used them for prescription sunglasses.


Do you normally wear glasses?


I need them to drive and I wear them at work. I didn't appreciate how much I was missing them outside until I got some.


Love this too!


I got a couple of pocket operators, about $175 in total. Opened up a whole world of electronic music for me. Serious gateway drug. I'm composing again after decades of dry spell.


Which ones? I got a PO12, PO20, and PO33. They're great!


Thanks! After a bit of poking around, just got a PO-12 to have a play with.


Wyze Smart Deadbolt. $79, secure, and convenient. You never have to worry about losing a key again. I live in a cold area and it works reliably. The auto lock is so nice so you don’t worry about if you locked the door. Also great to allow guests or contractors in if you can’t go home to let them in. Makes my life so amazing.


Yeah, smart locks are nice. I have Nuki 2 and am equally happy. Even though it disconnects from the wifi, get huge latency on notifications and battery lasts only 2 months at most, the autolock and opening door with fingerprint is total addiction and works flawlessly. If all other features worked as promoted for that price, I would buy it for all the doors. A friend of mine wasn't so lucky, his Nuki blocks constantly and drains battery after a couple of days...

I was always behind an open door during the day until I bought Nuki. Now I am always locked and surprisingly, after only 6mo of usage I am very uncomfortable when autolock is not enabled.

Not needing a key but still having a backup in case it stops working is awesome.

It is expensive though, Nuki without fingerprint reader and dor sensor is less than $200 but with everything price is around $450


This box cutter tool, which is <$12 https://a.co/d/aOxoVOp. It makes opening packages so much easier. It doesn’t have a blade, so it’s much safer to use than scissors or a knife.

It says it has a "ceramic blade" that "stays sharp up to 11x longer".


One of my amazon packages randomly came with some warehouse workers blade that must have dropped in there. These are really nice!


A better tool for basically the same price is a OLFA LA-X. It's a Japanese designed box cutter which has a retractable blade on one end and large dull metal pick on the other end for quickly stabbing packages open.


OLFA is great. I got a box of 12 touch knives and I always have one with me.


If it doesn't have a blade, how does it cut then?


I'm assuming it is the same as using your keys to open a package?


In Switzerland, the public post company provides a service[0] which scans your incoming letters (i.e. their content, not just the envelope) and makes it available via the web and an app. I started using this service last December and am very happy. Kinda looks like I am forcing digitalisation upon organisations who don't want to make progress on it :D

It costs 9.99 CHF per month, hence within the limit of the post, and very much worth it.

For those in the US, the USPS (postal service) provides this for free. Yay! Probably because of theft problems :-(

https://faq.usps.com/s/article/Informed-Delivery-The-Basics


It seems I have not been clear enough: This service opens your mail and scans the actual content of the letters to PDF files. It's not just the address box or the envelope!

That USPS service you posted is already available for free from Swiss Post as well.


Oh, you were clear, I just missed it. Cool service :-)


Portable 16" monitor with 4k resolution and USB C passthrough. Very handy when travelling. It makes me much more productive when working from a hotel room or anywhere else, and it's just about the size of a 16" laptop, but thinner.


I bought the 1080p variant. It makes a great preview monitor for video signals, camera output etc. I'm considering buying a 4k version with touchscreen for travelling, which fits well to the 4k touchscreen on my laptop. Not sure if I actually need touch for a side monitor, though. Or even 4k for that matter...


4K makes a lot of difference to me, just because I can change resolutions without ever seeing pixels. I don't have the touchscreen version, and I don't miss that functionality. But I see that it might be useful for some applications.


Ooh, nice, which did you purchase?


This one: https://www.uperfectmonitor.com/products/4k-portable-monitor...

Got it on eBay with a coupon for just under EUR 200. Really happy with it so far.

I got into Audiobooks this year. I first listened on headphones or just phone loudspeaker (thought it's OK for voice).

Then I bought JBL Go 3 and it's a different experience. The speaker is compact, lightweight and has a nice design. Sound quality / loudness is fully sufficient for voice and does a great job for its size for music as well. It's waterproof, now I listen even while showering. The only downside is lack of battery level indicator.

BTW, Audible subscription is a surprisingly good deal. You can have basically any book for $10 (even those which cost $30 on Kindle).


I used a JBL Flip 4 speaker to listen to audiobooks and podcasts while floating in the pool for a while. Bluetooth doesn’t penetrate more than a few centimeters into water, so I’d just put my phone in a dry bag, tie it to the side of the speaker, and set it adrift. Way less clunky than a headset and worked great


There's $100 waterproof bone conduction headphones with built in storage that works great. Speech is pretty trippy and well suited for bone conduction. Only issue is you have to find mp3s of audio, which usually means sailing high seas.


There are, but that limits the number of people listening to one, I don't like the feeling of wearing headphones though, and I didn't want to lose sync with podcast/audiobooks either :)


I got the JBL Flip 6 for audiobooks! I compared the 4 to the 6 but the 6 had two tweeders that really allowed for crisp narration.

"The main focus is Vipassana, where you’re taught to cultivate a quality of mind called “mindfulness,” which is simply a state of clear, non-judgemental, and undistracted attention, moment by moment, to the contents of consciousness."


His approach to meditation is just so much better than any other I’ve found. It’s actually in inquiry into your mind instead of just “look now you’re calm!”

The Alan Watts series also has been amazing. I’ll admit I was reflexively offput by Watts just given his pop culture popularity, but wow he has some incredible ideas shared in a really remarkable way. Well-earned popularity.


I really like both the Adyashanti series.


A Nutr machine so I can make quality nutmilks at home instead of buying store bought stuff loaded with nasty preservatives and very few nuts per serving.


Do you do oat milk? Wondering if these devices avoid the gel-like consistency that forms when I make it in my blender.


I’ve done oat milk with quick oats, seemed fine to me.


Philips Sonicare 7300 electric toothbrush - this thing is awesome, every time I brush my teeth they feel super clean and smooth like porcelain. $149 one of the best purchases I ever made. https://a.co/d/2fFJgow

Another product that improved my life is AirPods, if you’re into the Apple ecosystem they’re worth every penny.


If you don't like airpods but want the apple ecosystem, the beats fit pro are a nice alternative.

https://www.beatsbydre.com/earbuds/beats-fit-pro


Beats were really bad in the past. These were the first pair of Beats that I actually like and didn’t die within 13 months of use.

I am in the Apple ecosystem but prefer them to my AirPods Pro.


Mine have been going strong for a few years now, even with daily use.


Worth mentioning, if you do get a sonicare or any elective toothbrush, go much more slowly than you think. Makes all the difference in the world.


Canon selfy CP1500 (photo printer). For the colors, the lamination and the software. It's significantly better than competitors' (I use it to match colors when oil painting and Im picky like an engineer). My guess is that competitors have the same HW tech ("4pass thermic sublimation") but not the software and/or color sensors thing.


I've got a Selphy too, they're really good, kind of curious why they don't use black as an additional colour though (maybe it wouldn't make much difference?).

Would also be nice to have larger versions too.


Spending tracker - https://apps.apple.com/us/app/spending-tracker/id548615579. Really simple, offline & with a one-time purchase option.

$23 Bluetooth earbuds (late to the party)


I generally hate dealing with bluetooth headphones (extra non-replaceable batteries to die then die! Extra drain on your phone battery! Run a unique ID tracking beacon all the time! Have a fight every time you want to switch sources! Pay more for inferior sound quality!), but the difference between the no-names and the mid-tier brands is shocking.

I've used a couple cheap wireless earbuds all of which were _awful_, and some over-ear TaoTronics headphones that are bluetooth-or-wired which are pretty OK, but I decided to try going up a tier and got a pair of Anker Soundcore Space A40 earbuds on sale for a bit over $50, and their ANC is _fabulous_, their pairing only rarely does something frustrating (they'll remember two different devices, which helps), they're actually reasonably comfortable despite being a larger object supported from the ear, etc.

One thing I realized the first time I had them on a flight is that the _lack_ of a simple way to hook them to a standard 3.5mm source is limiting - it means they can't take over for as many tasks from a wired pair as they otherwise could.

On the topic of headphones for loud environments: I've had mine for several years, but Plugfones (I have their Guardian model) are also a worthy object; earbuds which are also ANSI S3.19-1974 29db NRR hearing protection. Really nice for both noisy environments and working with power tools.


A bit late to the party, but in case you track replies, I can recommend the Avantree "Audikast Plus" device. Negligible weight, it gives you Bluetooth capability for two simultaneous headphones as long as you can plug it into a 3.5mm jack. I have been carrying it in my travel bag for years (the current model looks identical but is Bluetooth 5.0 compatible) and it makes our flights and hotel trips a delight (sound experience, I meant).


> they're actually reasonably comfortable despite being a larger object supported from the ear

On that note, there seems to be an explosion of "open-ear earbuds" going on right now - just between October and November, the amount of designs on Amazon seems to have doubled. These sit on your ear instead of inside it, and are a ton more comfortable. I couldn't stand normal earbuds and have been sticking to wraparounds, but these open-ear designs work for me.


I bought four from different vendors over about 6 months. Every one of them had one bud fail within weeks.


What brand / model??


They are so cheap I had 3 different brands.... Waiting on over-the-ear ones right not because all other ones end up falling


My Thinkpad Yoga 11e running Manjaro, got this refurbished for $160.


A set of nice flashlights. Why walk around in the dark? Some that I like: Sofirn SP36 BLF, LT1, SC21, HS10. Wurkkos TS10 (and I’ll be getting a TS11 soon.)


> Why walk around in the dark?

Walking around in the dark outside can actually be really nice. Your eyes adjust and, of course, it's never completely dark (moonlight, starlight, etc).

Torches (flashlights) are fine, but ppl tend to overuse them, in my experience.


Love my hexbright.

If they were still being made, I'd get more.


I can’t believe it’s already been ten years. My hexbright is still kicking. I’ll miss it when it will finally dies on me.


>I’ll miss it when it will finally dies on me.

It will never.

Most common faults have well documented repairs. Worst case scenario you can get a new PCB made.

You'd have to physically destroy the enclosure to really lose your hexbright. I don't think anyone makes replacement ones.

But as I understand it, even that is documented, and the source hexagonal prism is common, so at least it's not impossible.


Sofrin HS10 headlamp $20. https://www.sofirnlight.com/products/sofirn-hs10-mini-headla...

All those times you're trying to use a flashlight around the house you probably would be better off using a headlamp. You can also use this as a flashlight too if you're weird like that.


Bifocals from Zenni. $39, stylish, get to brand them myself, and the lenses are better than my local boutique optician ever did at 40 times the price


How are the lenses better?


Don’t know if it’s advances in technology or what but the (cheapest) lenses give me crisper vision.


3M Peltor Premium Plus Earmuffs X3A

https://www.3m.co.uk/3M/en_GB/p/d/v101190004/

They're light, stylish and work amazing. The world quiets down and it's (way, way) easier to go into the flow.


These type of muffs can be problematic when they limit communication or impair situational awareness. Many applications are better off with a pair of amplifying earmuffs. As an example, Walker's Razor Slim are good for sustained and impulse noises, and don't impede communication or situational awareness. With everyone using them, you can talk to people farther away. They do impair speech direction localization and conversation discrimination because the phase of sounds aren't preserved exactly as they were.


Good idea. If only there was a good solution for glasses wearers...


I have a friend who wears glasses and they say they can wear both at the same time with no problems. The (glasses') temples are pretty thin, though.


Cool, thanks!


Bose SoundLink Flex Bluetooth Speaker

I was blown away by the sound quality produced by this relatively small speaker. It has very rich bass and other frequencies sound very good too. I often carry it around my apartment and use for things like music, audiobooks, calls (unfortunately the built-in mic isn't that good), etc.


MaxiNutrition Hydration Tabs. Much easier to drop into a glass of water than powder-form electrolytes (no messing around with a spoon etc). Also something to keep in your pocket/bag on a longer bar night. I can't guarantee the nutritional value being a nonexpert but at least the convenience is great.


What's the advantage of this for hydration when compared to plain water?


It's got what plants crave. It's got electrolytes. - well, at least the electrolytes part is true. When you sweat heavily, you lose minerals and salts, which can become detrimental to performance or even dangerous to your health during intense workouts. Hydration products [claim to] replenish these.


Usually plain water is fine but sometimes you need a bit of extra electrolytes to rehydrate. I wouldn't drink too much of them though.


Weighted blanket


Agreed just don’t go too heavy. I did and I am unable to move under it.


Does it really makes a difference ?


Depends on the kind of sleeper you are. Personally I can't sleep even in the summer without some amount of weight from fabric on me, which I know doesn't make much sense but it is what it is.

My roommate tosses alot when sleeping and a really heavy blanket keeps her still, which she says helps her get a deeper sleep


I have the same preference, especially when falling asleep.


I can't use it at all, but my partner loves it and now packs it when we go on trips.


I have a 7kg weighted blanket that sits on top of my regular blanket at night and I love it. I feel like don't wake as easily, and overall sleep better. And it's so comfy.


A 15 lb weighted blanket is the best sleep I’ve ever gotten


It feels more cosy, but I can't really say if it makes me sleep better.


This bike multitool. When not biking, it kinda doubles as a fidget toy for me.

iPad pdf reader & annotator designed for sheet music. As a “tech” husband helping out a non technical musician wife it’s a game changer


A natural daylight alarm clock made my mornings a lot more tolerable (I'm up at 5am)

I won't recommend a brand though, while the Philips SmartSleep has nice color and smooth gradients, its so basic it doesn't even have a backup battery


I rather like my 'Mi Precision Screwdriver Kit', magnetic screwdriver set


New running shoes


Flow Club. Hands down the best thing I've ever done in my life.


Isn't that kind of like Focusmate?

https://www.focusmate.com/


Similar. I dipped my toe in the competitors, but honestly the ease of use and interface combined with how much more productive I am after using it. I recommend flow club.


A trip to a repair shop to fix the rash scratches on my car’s wheel rim with polishing, claying and a repaint, costing $55. All other offers of the service were in the $100~$200 range.


A chair cover. I have a faux leather chair and it would flake, leaving particulates everywhere.

Obligatory noise cancelling headphones. Get a good pair.

Apple OEM chargers. They work so well for fast charging.


An RPi 4, 8GB. I run heimdall, calibre-web, nginx, and PiVPN/wireguard on it.


Similar, yet different: VisionFive 2 (RISC-V).

Runs all sorts of tasks.


a 3-in-1 wireless charging pad for $30 from amazon to put on my bedside table.

now I wake up with my phone at 100% every time!


Would you link to it? Mine always die within a couple months


What devices do you use this to charge aside from your phone?


UnRAID Pro license.
