For comparison: Texas Instruments sell something called the EZ430 Chronos watch, which has a much lower-res display, a proprietary RF protocol with a USB transceiver, and a bunch more sensors including 3-axis accelerometers, pressure and temperature.

It is based on the MSP430 microprocessor which is much less powerful than this thing, its capped at 16mhz or something IIRC and only has around 8K of program space. It is however about a third of the price.


Yup, but we've got Bluetooth, a fantastic OLED screen, and example Python, Android, Blackberry code!

Also, we're right here on HN to answer your questions!

>Yup, but we've got...

Indeed. They are very different propositions. Hence I said "for comparison" :)

Ok first question:

Why only one button?

Two would have been really nice for most things (like back and forward in powerpoint/itunes).

Edit: Another one:

Why don't you ship outside the US/Canada? I considered buying one, but I'm in Germany :(

We choose one button to keep it simple (and quicker to get to market). You can do a lot of things with just one button, just look at the single button on the iPhone! For example, you can do two actions, like click and click-hold.

I've experimented with using a single button (a Griffin Powermate, actually) to control all of my electronics: one tap toggles the lights, three taps changes lighting scenes, press and hold/five taps turns the projector on or off, eight taps toggles "party mode," ... I'm quite convinced that multiple buttons would be better :).

You could not do much on an iPhone without the touchscreen.

also, double-tap.

Neither seems very intuitive for "back" and "forward".

Can the watchband be removed to make it a pendant (or pocket watch) ?

Looks too big for a woman's wrist? Can't find actual dimensions...

RE Pocket-watch: If you're going to fish something out of your pocket to look at alerts, what's the advantage over just grabbing the phone itself?

There is a picture of a woman wearing the watch on the their blog. Looks a little big but not bad.

Ah thanks for pointing that out, didn't read the blog.

I think I'd still rather wear it like you would a security badge with a lanyard or like the old-school mini-pagers in your pocket with a chain.

What are the dimensions?

(I'd love an accelerometer - sure you guys are well aware of the possibilities)

96x128 pix full color OLED display

Ah - sorry - I was after physical dimensions - i can kinda figure it from the videos, but I'd like to know if it would actually fit on my writs comfortably.

Post the STL file for us 3D printing enthusiasts - Apple posts blue prints for us case hackers ;-)


I know this is off-topic but does a similar thing exist for the nexus one? Is there a repository for such files?

I really wish there was - I may get around to asking for this info, but I bet you've got to sign some type of license or pay fees. I don't know - I haven't tried.

Are you interested in making a case or something similar?

Hey, I know this must be there in the sdk docs somewhere, but can the knob on the side of the watch be used as an input device? Also, I wish I had more upvotes to give you.

EDIT: Oh, never mind, just saw that its a button, not a knob.

Just a heads-up: we've got a limited supply of the first batch (as some intelligent commenters below have deduced). If you'd like to get hacking soon, I'd suggest picking one up! The first batch starts shipping tomorrow...

What's the actual hardware inside? Do you expose (quasi-)standard ARM JTAG?

We're trying to make it as easy as Arduino to develop an app for your watch! To dodge the arm-gcc toolchain issue, we've built a cloudcompile system which allows all platforms Mac/Ubuntu/Windows to have an equally easy time compiling. Simply code your app in C, then run our python script to compile your code and load it onto your watch, wirelessly!

Also, your terms of service (http://www.getinpulse.com/terms/) states that you claim rights over information I upload to sites run by Allerta. That must include code I upload to be compiled, correct?

From the terms: "hereby grant to Allerta a perpetual, irrevocable, non-exclusive, worldwide, royalty-free license, with the right to sublicense, to reproduce, distribute, transmit, publicly perform, publicly display, digitally perform, modify, create derivative works of, and otherwise use and commercially exploit any text, photographs or other data and information you submit to the Website (collectively, User Generated Content) in any media now existing or hereafter developed, including without limitation on websites, in audio format, and in any print media format."

Good point.

As I mentioned, we're releasing the entire SDK with instructions on how to compile using the full arm-gcc, right on your local machine. We just started off with this cloudcompile service to make it super easy for everyone to get Hello, Watch! (http://getinPulse.com/apps/hello_watch) running.

We are developers ourselves and committed to providing the best experience possible. We'll work fast to get the full toolchain out there.

Your python script uploads my code to your server and sends me back a binary in return. What happens when that server goes down?

Getting people up and writing code on devices quickly is awesome; but sending code (unencrypted, even) off is pretty shady, particularly since you're not disclosing it to anyone.

Arduino manages to have a cute little barebones IDE based around an actual compiler; and they provide full hardware docs, links to datasheets, the works. You're doing exactly the opposite of that. Even Apple will let me compile code for my own iOS devices -- after I've paid the $99/year fee or jailbroken, of course...

It is interesting to note that the EZ430-Chronos can last about 6 months on a charge if continuously reading BlueRobin data (which is a one-direction wireless data) while this inPulse aparently can only last 2 to 3 days recieving data over bluetooth.

Less powerful processor and cheaper display might be a good thing, depending on your uses.

From http://www.getinpulse.com/faq/

What is the battery life like? With aggressive power management (turning the screen off most of the time and leaving bluetooth disconnected), it can be up to 3 days. If bluetooth is constantly connected with the screen turning on periodically for alerts, you can expect 25 - 30 hours. If you have a processor-intensive application and are using the full capabilities of the screen non-stop, you can expect 2 - 3 hours.

So unfortunately it seems that the battery life is the biggest issue with inPulse

The _state_ of battery technology is the biggest issue _for_ inPulse. There's not much they can do, given the lack of viable battery technology available.

They _might_ be able to save a decent amount of battery life by using e-paper, but you lose color, and I'm not sure in practice you'd end up saving much power over the OLEDs they're currently using.

Even doubling the battery life of the battery would barely give it a week.

Seriously. When one has a 60x lead in lifetime over the other, you don't blame 'poor battery technology', especially when they use the same 'poor battery technology'!

Blame other interesting things you might want to wirelessly communicate with for standardizing on power-hungry Bluetooth rather than using a lower-power wireless tech (zigbee, ANT, etc) instead/additionally.

Even by disabling Bluetooth, the battery life of these watches is abysmal.

E-ink, or an LCD variant with a low-power mode (Pixel Qi or a transflective panel) would be a nice improvement, I think.

it can be up to 3 days

If that's their optimistic estimate then I'm not sure I want to learn how long it lasts under real world conditions...

Have you considered adding a crank?

(actually only half-joking, although I fear the machinery would not fit into such a small device)

Yeah. TI aren't lying when they describe the MSP430 line as 'ultra low power.' You can run them on fruit (grapes etc.)


(the video is worth it for the 'joke' alone.)

I bought 3 EZ430s. While they're interesting concepts, they're not without their problems (most notably not keeping time very well on the default firmware). You do come up against limitations and they're more of a proof of concept than anything else.

Wow! I've always been looking for something of this sort but I've never found one. Thanks for the link!

My eZ430 only took a year to ship. Can't wait for this :D

What I really need is a stylish women's watch so my wife can know when her phone is buzzing in her purse!

While it doesn't appear to be a women's watch, this might interest you:


Bluetooth bracelets are available and pretty cheap. Haven't tried them, but: http://www.dealextreme.com/c/bluetooth-headsets-508?search=b...

Awesome!!!! They even look good too. I might think about getting one and whip up an Android library for people to use.

Question to anyone reading this. What would be a good use to notify users? There was an article on HN about startups using a visual dashboard: http://mygengo.com/talk/blog/why-your-startup-needs-a-visual... I think something like that would be cool to have. Hook into your KPI's and have that information right there on your wrist.

We've even got a sample Android project to get you started. Download the SDK and example apps: http://www.getinpulse.com/images/pulse_sdk100.zip

Awesome thanks!

I just checked the specs, "4 days depending on display/Bluetooth use"

Even if its two days of full time use, thats great.

Correct me if I am wrong. I think I have found a way to track sales of both the models on sale.

Depending on how many items you ask for in order screen, it lets you go ahead or displays "stock unavailable".

For the Mettalic Silver, It seems 57 items are available at the time of writing. and for Black Anodized, it is 108. I have to take a reasonable assumption now to get the sales numbers (may be 200 at beginning?).

56 and 107 now. Seems you are right.

50 and 94 now, seems the black is selling faster.

This is very cool. I own a few Timex Datalink watches which are also programmable. Timex recently discontinued the Datalink and they're already becoming very hard to find. I hoping some company would come up with a suitable replacement but unfortunately nobody seems to build something with a comparable design.

The advantages of the Datalink are that it always shows the time (no button press necessary), the battery lasts an entire year, is water-resistant, and is small and subtle. It also just makes a damn good watch without any of the programmable features. Every other programmable watch available is anything but subtle, with a display that isn't active all the time, and has to be constantly recharged. Those are considerable failings for a watch.

What the Datalink lacks is a denser display (but remaining as 1bit LCD is ok), any sort of wireless (ANT+ would be suitable), and sensors (pulse, altitude, position, etc). It could also use, obviously, a faster processor with more RAM and storage (it also has 32k).

The price for this watch is fantastic but it's still just not quite what I'm looking for.

This is a very hacker-unfriendly device. I wouldn't buy one.

The SDK's compilation tool doesn't invoke a compiler; it uploads your code to a service running off of

The Arduino is fantastic because the bootloader is open-source, the hardware is open-source, and it's easy to find out full information about the hardware and pull the MCU datasheets yourself.

How can you call it "hacker unfriendly"? The thing is designed to be hacked, that's the whole point of it.

The Arduino and this are two totally different classes of devices.

For staters, this appears to be very much about the hardware. I wouldn't expect it to be open source, just like the iPhone or Motorola Droid you can develop your own apps for doesn't have open source hardware. You don't actually have to be granted access to 100% of the codebase and hardware layout for a product just to develop a neat application around something.

I saw this and immediately thought of 5 or 6 cool uses for it so I bought one. Sure, if I was going to build some kind of a product around this, or develop an app that was going to be my retirement income, I'd want a little more information about the company and their licensing models. But for a $150 hackable gadget, this thing is one of the coolest toys I've seen in a while.

I think it's a pretty good idea, but the ideal solution would be both a CAAS and the opened sourced toolchain that worked on at least one open source platform. Doing that is probably easier than releasing something cross platform like arduino, and for most people is going to be easiest to use.

I'd love to hear a counter to this. I was really close to buying one...

Hi Guys, Eric from inPulse here. We're trying to make it as easy as possible for people to develop for inPulse. That's why we've built a cloudcompile service. No messing with DLLs, drivers and other annoying parts of embedded coding.

I think we've succeeded! In our beta testing, users were able to go from downloading the SDK zip to loading their first app on inPulse within 5-8 minutes. I think that's pretty impressive for a startup hardware biz.

If you'd like to setup the arm-gcc toolchain and compile your own apps, absolutely no problem! We'll have instructions online shortly. If you need them faster, just email devsupport@getinpulse.com

It's certainly easy to use, as long as the server remains up. But do I still have full control over the code that I upload to you, or does it count as "user-generated content" in http://www.getinpulse.com/terms/? What privacy guarantees do you make regarding the code that I upload? (Hopefully very little; it is transmitted in the clear, after all..)

We live in a world where device vendors (even small ones) routinely use technical means to thwart hackers and other tinkerers. Often, this is done under the guise of usability or security (sometimes with some justification, even). Plenty of people don't mind trading away some control for stability or ease-of-use.

This is a forum for hackers, and you just called your device "hackable". I'm saying that it's not, currently; it's a black box with an SDK that does cloud compilation. You don't document that fact anywhere or provide an ready alternative, and there's no information about what's underneath your API, either OS or hardware.

This is extremely important - the claim to user-generated content is either boilerplate and wasn't intended to apply to actual software, or it is specifically intended to apply to the uploaded code due to the cloud-compile service.

The question has been asked a couple times here - is there an answer?

Boilerplate. We'll get the lawyers on it and get it fixed.

You've made some very good points. We'll strive to improve over time, and you comments/questions here will help guide us. Any and all comments are welcomed to devsupport@getinPulse.com

I encourage you to try out the hardware, throw it on your wrist and wait for the amazed looks from passersby. It's quite awesome having a net-connected terminal (I pair my inPulse with my Blackberry) right on your wrist.

Your marketing speech just creeped me out, FYI.

Sorry, my bad. :) Just trying to encourage people to try it out. It really does feel cool to have your watch vibrate when you get an important email.

For technical sites like Hacker News (and to some extent, reddit), it seems like marketing speech is actually more likely to turn off potential buyers than attract them. See the IE9 AMA debacle on reddit, for example. We're hackers here, and blunt truth tends to be valued more than softer wording.

I read it as more of a politic answer, there's been a lot of inpulse bashing it seems over what appears to be something that they are doing to try and help, not thwart hackers.

Encouraging us to get one for the Blackberry is all well and good, except its pre-order only, not shipping yet.

I wish the blackberry 'edition' was $99 (for black.) Then I'd get one. It seems disproportionate to the blackberry cost itself at $199

I've never heard of a cloud compile service, but I think in this case, it's a good idea. Especially since not many people have experience with cross-compiling.

One of the things that make Arduino so popular is the ease of use in getting code a) to compile and b) get uploaded to the device. If this works via a service, then so be it.

But, I would like to see instructions for setting up a local amr-gcc toolchain, just to be complete.

The other cloud compile service that I'm aware of is provided by NXP for one of their microcontroller dev boards. http://mbed.org/

Those mbed things are completely brilliant.

"ARM Cortex-M3 Core running at 96MHz, 512KB FLASH, 64KB RAM and lots of interfaces including Ethernet, USB Device and Host, CAN, SPI, I2C and other I/O."

<200mA, $59

I want one, but I already have an arduino thats been laying around unused and unloved for some time :(

Appcelerator Titanium, a relatively prominent open source alternative to Adobe AIR, does cross-platform app compilation on a 'cloud compilation' service:


I'm impressed with the price point. It's about what I'd expect a device like this to run if it were a higher-volume product selling through mass-market channels, rather than a low-volume, enthusiast product selling only through the manufacturer's website.

Are you guys courting retailers like ThinkGeek?

Do you know of other retailers like ThinkGeek?

(I like ThinkGeek, but I'm curious if there are other, similar stores.)

SparkFun, if you're not already aware of it, is only vaguely related to ThinkGeek, but it seems to me anyone looking at a hackable watch would be right at home there.

Looks cool.

But when I do upgrade my venerable analog watch, it's probably going to be to a http://lunatik.com + ipod nano 6g. A little more expensive, requires a jailbreak, but a hell of a lot more functional, and doesn't require uploading my code anywhere to compile it once jailbroken.

That was my plan too with the hope that I could do something similar to this and load/write my own apps. I actually received my lunatik kit with a ipod nano 6g about two weeks ago.

1) the ipod nano 6g has not been jailbroken.

2) the ipod nano 6g has no bluetooth built in

This watch is a better fit for what i want to do now - get up and running now with a programmable wrist based terminal.

I love the design of the lunatik but until the nano 6g is jailbroken I'm just wearing a nano on my wrist. The novelty of which has worn off since I can't hack it to do anything special.

Has the nano been successfully jailbroken? Last I saw was that some of the images/text could be changed but I wasn't aware of anyone getting actual new code running...?

Seems I was mistaken and the answer is "not yet".

Well also, it doesn't run iOS so a jailbreak wouldn't be that interesting..

On the contrary, it would be a very interesting little platform to play with.

Just because it doesn't run iOS doesn't mean you couldn't write code for it :)

I'm puzzled to see such resoundingly positive feedback here. Props for the hard work on building this product out.

However, in a world of smart phones I can't imagine ever using a watch like this.

Watches have been relegated to primarily fashion items, I can't imagine why you'd want one that runs code.

Sorry for the harsh review, best of luck.

Not a motor/bicyclist eh? :)

Having access to information without having to dig your phone out of your pocket (not to mention a phone you can't operate with sturdy gloves) is very useful in such situations.

Which reminds me; how "weatherproof" is this thing?

Is this device "Made For iPhone" (http://developer.apple.com/programs/mfi/)? If it is, I suggest putting the badge on your front page. If it's not, I suggest applying for it to be.

Does this run multiple applications or do you have to plug it in each time you want to run a different app?

One app at a time, right now...but we're working on getting multiple apps running as well! Good point.

So I can't have a watch and notification app running on the watch? Guess you'd have to make them into one application?

If you do get that working, does that mean new hardware?

The devices look cool from a technical perspective. It could use a few more sensors (GPS, gyro/movement, temp, etc.) but I'm sure that will come.

The only problem, I think, is that they're not very stylish. A bit too large/clunky looking. I'm not sure how to fix that while keeping the display a useful size. But that what geniuses like you guys are for!

If they really take off, I'm sure the design could become much smaller and more elegant over time.

I ordered one to hack about with. If it becomes part of my daily routine I'll probably have my jeweler in Detroit hook up a more attractive case and band for it.

Agree on the sensors, it would be nice to at the very least have a dead-simple accelerometer, but I also know what goes into bringing a piece of hardware like this to market. The $150 price point probably doesn't leave a ton of margin, and it's just on the cusp of not having to be a "considered purchase" for people. Adding more stuff would drive up the manufacturing cost and price into something that starts to become a $399 product and the number of experimenters who will buy one on a whim drops dramatically.

I think these look much better then putting the Apple Nano on your wrist: http://bit.ly/hnLUkQ To each their own though. =)

As for applications, yeh GPS, Gyro would be great.

Here's the TikTok/LunaTik link: http://www.kickstarter.com/projects/1104350651/tiktok-lunati...

They raised $941,718 from users, so there's definitely a market for style. It's touchscreen, costly (nano+holder) and non-hackable.

Are you looking for investors?

Looks very nice. If it had a couple more buttons, it would be great for a workout tracker.

Give it more buttons and I'll buy it.

Few comments:

* Your 3rd video is the most presentable one and best intro, make it on top.

* The screen seems not be a touch-screen since not mentioned in features. So seems like only way to navigate the on-screen "buttons" with a single physical button is to press it until it cycles to highlight screen button and press and hold it to select. This does not seem to be a good UI.

For a v.2, you either need to use a capacitive touch screen, or make that single button you have on the bottom face of the watch like iphones, and have 4 to 6 buttons on the side, 2 to 3 on each left/right side so that app developers can program their screen buttons to float to left or right and user can just press the corresponding button. Of course the side buttons will need to be "concave" (not sure the right terminology for it) and be seamless on the side and not use that same old metallic button used in many watches. Minimalist does not work on a non touch-screen. Remember that even the ipod retained all 6+scroll buttons in its 10 year history.

[Edit: After a bit more though, if the side buttons are to be implemented, they need to go on only one side since the opposing side need to be empty for the opposing force of the thumb.]

Even if you decide to use a touch screen (pro version?), get rid of the side button and make it on the face like the iphone -- not only does it currently not look right on the Black Anodized version (some design work may be needed for a front facing button to look good on the Metallic one), but it will also hurt the users' finger less being a iphone-like button on the front for intensive apps like games.

* Why is the Black Anodized version cost $50 more? I would imagine the opposite. What does it have that the Metallic doesn't?

* Most people who spend $150+ on a watch actually cares how good it will look on him/her. Either make a pseudo (bunch of images wrapped in a slider div) 360 model view or take a bunch of pictures in different angles standalone and on different wrists (men and ladies). Have its dimensions stated like so:

      | |   ^
      | |   |
    |     | |
    |<-z->| y
    |     | |
      | |   |
      | |   -
(ditto for its height dimensions).

* Why is the Blackberry features page totally hidden on the footer? That should be your main feature! In fact, write a hello world ASAP that talks to the iphone/ipad/android (eg. notifications or different vibration alerts for different notifications), it will probably 2-10x your sales and developers.

* Nitpicking - the "Buy it now" on the features page needs to be on the bottom, no one will buy until they read the features. And after reading, there's no "buy it now" action avail.

* Find a way to tap into the ipod nano watch or other smart watch community, you should get converts or potential customers there.

(Edited to format the diagram and more details.)

x (strap)= 26mm, y (height of watch casing) = 50mm, z = 36mm - Thanks for the tips, incorporated. - No touchscreen at moment. I like the way you think about wearable UX. If you're interested in continuing the conversation, please ping me at eric@getinpulse.com - We're testing the selling points. Right now with supply being limited (early stage startup) we decided to let people hack away at their watches. I'm sure as our capacity improves, we'll retarget consumer verticals. - Here's a cool bit of community news, OpenWatch for Android now supports inPulse (http://beta.smartmadsoft.com/). Marcel, the creator of OpenWatch, was able to get started with our dev tools and integrated inPulse in a very short time!

You can reference the dimensions to something everyone knows too, like an SD card or ipod nano (not something everyone knows, but it's a good way to convert potential ipod nano watch buyers if it's smaller and better looking, which it does seem to be, even compared to the Metalic tiktok variant).

Here's a quick comparison between the iPulse, SD Card, and latest gen iPod Nano with sizeeasy:


Only the watch body itself is shown: SizeEasy only supports cubic dimensions, so I couldn't find a way to show the wrist band.

Also, SizeEasy requires all three dimensions be provided, and since I couldn't find official dimensions anywhere else I used those cited around the web, for example:


Overall, decently sized but definitely not head-and-shoulders above the Nano.

A bit more on v.2 side buttons: Make them on one side only, probably the standard right side, to account for need of opposing thumb's empty space. Make it 3 buttons, all three for single action contextual buttons for single action context menus; top & bottom can also act as scrollers for lists and long messages, middle button being 'OK' button. This button layout will still be useful even if you have a touch screen because of the small screen real estate.

A bit more nitpicking suggestions:

- First 2 videos are too noisy, replace/edit/re-do if you have time.

- Overall tone of the website and watch's usage and features is a bit too hacker oriented. This may be the audience you're after now. You'll need to sell to mainstream audience after you figure out what they are after. IMHO, its the smartphone/tablet pairing. Do not take no as an answer, either talk to Apple to get around iOS terms or if that fails, start with the jailbreak route.

I don't really see the point of having a watch nowadays. I usually just look at my phone for the time. This watch seems to do some of the stuff a standard smartphone does, but is more limited. At this point in my life, I'm trying to do what I can to limit the number of various gadgets I carry around on my person. I would rather have a small little device that does everything pretty well, than 50 devices I have to lug around that do everything perfect.

In a sense its similar to using your computer instead of a television. You can access more interesting internet videos online, and usually don't have to watch commercials because of ad blocking software. You can play video games on your computer instead of using a console. Your computer could hook up to a projector or HD Television as needed. You can read books on your computer. You can call people on your computer. You can IM/Email/Facebook on your computer. I think the future will be far fewer devices that can do a whole lot more. This watch seems like a step into the past.

I would buy this right now if it worked with iPhones. I love my iPhone, but Apple's restrictive policies are really starting to get to me.

Given the schematic and gerbers, I'd be willing to make a version of this watch that would talk to un-jailbroken iPhones (and other iOS devices).

Oh man, this looks /really/ cool. but the battery life? that's going to be a problem. I had a Matsucom brand OnHandPc back in the day, and it'd last a few weeks on a set of (replaceable) batteries. ran dos. It had a little joystick /and/ a bunch of buttons around the side, so it was fairly useful.

anyhow, an important use case for me, if I buy this, is using it as a bluetooth vibrator. I'm a SysAdmin and on call; but I'm not single. I want something that will wake me up without waking up anyone else who may be in the bed at the time. This means I need to wear the thing while I sleep; which makes charging... difficult.

I would give up color in a second if it would improve battery life.

Of course, I could aways just use a bluetooth bracelet at night and this during the day, but I'm bad at remembering things. I want to minimize the number of things I need to remember to charge.

I think one of the best uses for this product would be its secrecy.

For instance, I work at an establishment which bans the use of cell phones, but due to the fact that sometimes emergencies happen, a lot of people tend to sneak it in, anyway. So when our pockets buzz, our only option is to ninja it out of our pockets, hold it out of view of others, yet in our view, and check the notification.

With this invention, we would be able to simply hit a button on our watch, and not risk losing our jobs just to read a "hey how r u" BS text, or a missed call from an unknown number. Now we can tell whether or not we need to leave the office to return a text or a call without even touching the phone.

This is what I would use it for, anyway.

But, r u sure u cant get email notifications for those missed calls/msgs

I've had this page bookmarked for months, waiting to be able to order it (back when it was just designed as a bluetooth extension to blackberry devices).

Petty about US/CA shipping only, seems a pretty dumb move (unless there's some reason, other than shipping costs which you can make customers pay, for limiting who can buy it).

>(unless there's some reason, other than shipping costs which you can make customers pay, for limiting who can buy it)

Shipping goods for money internationally is a bureaucratic nightmare. A million possible edge cases to do with tax and so forth. This is why hardware startups often only take orders from their home country for their first batch.

I have zero experience in this area, but could it be that the manufacturer has to go through an approval process and/or have liability insurance in each country they ship to?

I can't speak to the tax issues, except to say that I've seen so many tiny companies manage to do it that I can't see it's a huge problem.

I'm surprised nobody here has mentioned Dynawa, yet.


I'm not purchasing one, but it's way cool that you got these things out there. I look at most stuff on HN and think "hey, I could build that!". I look at this and I think "wow, it's cool that someone managed to manufacture and build hardware on a small scale and sell it".



Not nearly as easy to hack as this Bluetooth with OLED, but still a watch designed by a single guy located in Tempe. I bought one from ThinkGeek a while back version 1 (pictured on his website, the picture on ThinkGeek is version 2) and I love it. It is unique and I always get looks from people.

It uses an MSP430 at its core.

Very cool stuff !

I think something like this, but bigger and wall mountable would be very neat. The obvious use case for startups is to use it as a dashboard with your most important metric for display - for example your google analytics traffic stats.

So is there a reason you have to send the code to an external server to compile it? Would like to be able to use this a year or so down the line if your server isn't around or is having issues...

This is mind blowing. Any plans for iOS support? Jailbreak or otherwise?

Hey, we actually do have iOS support, but yeah the device has to be jailbroken. You can read the FAQ here www.getinpulse.com/faq

The FAQ doesn't mention any jailbreak support. It just says that there's no iOS support :(

FAQ has been updated. We provide example code for jailbroken iPhone in our SDK.

Tell me I was not the only whose first thought was how cool it would be to build a cluster out of these things. But props to the OP, it looks like something I would spend hours playing with.

Just for you, Anemecek, I'll wear a beowulf cluster on my arm. I think it will vibrate off I you guys keep sending me email... www.getinPulse.com/images/toomanywatches.jpg

I didn't see this anywhere on your website: is the watch water-resistant? I know you're focused on the programmable aspects of the watch but to me this is important information.

Seems pretty cool! I laughed though at "intuitive one button interface" where the guy pushes it a few times, then he holds it in to do another function.

Couldn't find pictures of the back of the watch. Would be nice with an easy way to find good pictures of the product. Like a picture gallery.

Any idea how big the range of the bluetooth is? I'm curious how far away I can be from the other device I'd like to communicate with.

did anyone else think "red-green-refactor-wristband" when they saw this? Or at least something to hook into a CI or uptime service?

Very cool... I assume it tells time, too? :-)

Is Bluetooth the only way to get apps onto the watch?

Also, Python is the language to program apps in? They only language?

Python is a scripting language used on the receiving end of the messages, not on the watch. The language for code you run on the watch seems to be C

+ touchscreen for +$100 and I'd buy.

I am totally getting one, soonish. I confess, i have a Watch fetish :(

Better get one quick! First batch is moving...

Wow, I love it! Seems like a great gadget; I'll be purchasing one.

ok so programmable bluetooth item that vibrates, this is a great idea, so great I'm going to let this comment about it be lost amongst the sea o' comments

A bit expensive for a watch, but still very very cool!

I've paid that much (and more) for watches that did nothing more than tell the current time and date.

Their price seems eminently reasonable to me.

you paid for design

so does this keep a check on one' heart rate and send out an SOS email to Doc/911 if one is dying/drowning/ suffering from a heart attack?

hmmm, I am interested in seeing more detailed battery life information including for more "active" use.

http://www.getinpulse.com/faq/ The first question under Inpulse category will answer it. That's in case you haven't seen that one already.

Some love for Other countries, please

You guys make Waterloo proud!

how can i get one in germany?


iPhone/iPad/iOS compatible?

There is a similar product, Sony Ericsson LiveView, which can be worn as a wristwatch and paired with an Android phone: http://www.sonyericsson.com/cws/products/accessories/overvie...

Retails for EUR 39.50.

I do not own one so cannot say anything about how well it works -- just came across it randomly yesterday when buying something online. If the client is Android-based it is almost certain the protocol can be easily reverse engineered to make it hackable from other paired devices.

Looks like they have some kind of development support for LiveView: http://developer.sonyericsson.com/wportal/devworld/downloads...

I was very excited when I saw a demo of this, but the review I watched seems to imply that it sucks for bluetooth connectivity. I'm wondering inPulse has the same issues.

There is an update for the firmware on the Sony LiveView. (I own one, and it made a big difference in connectivity to my Nexus One.)

Any chance it has infrared for a TV remote that never gets lost?
