I think I'd enjoy the sort of company that would require an oscilloscope at a barbecue.
I would go to that party.
Proper ventillation for my home-residing 3D printer is the bathroom. Close the door and hit the fan.
You can guess when the idea hit me... :D
This is an amazing approach.
One of my former co-workers was a physicist who knew LabView and he used it for everything from parsing log files to sending automated emails.
It's run largely by a bunch of ex-PC gamer magazine journalists so their analysis of games and the issues around them are really interesting, and a number of them have moved into game development (such as Tom) which gives them an extra perspective.
Tom also does a lot of storytelling of his game experiences which is a lot of fun.
I'll add this to my podcast rotation.
I managed to somehow add a Wifi-controlled cruise control to an RC car that I borrowed from my kids, but somehow it ended up such a complicated mess that noone except myself can use it...
Complete side note....I has wanted something just like the Egg Controller, and got the "fireboard" as a gift. It works fantastically well, and I've wholeheartedly recommended the product since then. The technology stack is well done - changes are instantly reflected on the mobile/desktop/controller - and I've gotten 10x better at smoker cooking using the data collected. Some examples in case anyone is curious:
Here's a test of how well my oven PID works - https://share.fireboard.io/F65461
Here's me showing my grill controller board going bad (got a free replacement board using the data!): https://share.fireboard.io/C95FDA
Here's is a fun one - I wanted to track how much ambient temp changes the internal meat temp (per advice to open/baste as quickly as possible). TUrns out, it's good advice, there is a significant effect! https://share.fireboard.io/792FDC
etc...not affiliated with this company in any way
The world needs The Egg Controller. Take it to market!
As someone who's been through a thought process that was likely similar to OP's dad, I can say it usually goes something like this for me:
"I'll be damned if I'm gonna pay one hundred dollars for two thermocouples, a fan and an 8 bit micro running some PID library I don't even have to write. I have all of that crap in my junk drawer."
For the record you can bring an oscilloscope to a BBQ. And a DMM. And grab those bench supplies and the logic analyzer while you're down there. And of course you didn't grab the spectrum analyzer, but you ended up needing it after all.
Things get a little crazy; the better part of a case of beer gets consumed, and the next day you're watching your brisket come up to temp on your phone while you pop into the hardware store for a piece of sheet metal. Your BBQ looks like you are building a nuke with all of the smoke and colored wires snaking out of the big ceramic bomb casing to breadboards and test gear and antennas. A rainstorm would easily cost you five thousand dollars right about now.
Over the next week or two the purple PCBs show up along with some red ones and blue ones and a big box from Digikey. You have to wait a little longer for the OLED display to show up from that ebay seller in China because damned if you are gonna pay Digikey's stupid price.
So naturally it takes you until the next summer to solder it together and thank god it works perfect the first and only time you will ever use it because you really don't want to have to try to get your code to compile again.
This is where the "You should sell it" guy comes in. And so you say thanks, but you think to yourself "Damned if anyone's gonna pay six hundred bucks for something they can buy for a hundred."
We've got a small one and it's an amazing little machine, with the bonus of being able to select what type of wood you're burning as well.
I wish understatement would make a bit of a comeback.
E.g.: A "couple of nice little tricks involved" in making something work probably means you should ring up some patent lawyers.
We came to the conclusion that this wasn’t operator error either. He’d finished it but was too scared to power it up himself so locked it in the cellar.
Large electrolytic smoothing caps fitted the wrong way round, the smell is horrendous.

Try an average Chinese or even rubicon 10uF 63v ish cap which is in just about every bit of crap from SMPS to cheap toys. They go with quite a Big Bang.
I need to either put printed instructions on everything, or else dispose of them before I die!
That is my plan. My parents had so much stuff they had saved and I hated to throw any of it away after they died because most of it triggered specific fond memories. Yet the stuff they did get rid of, I never missed.
This reminds me of a kid I used to play MUDs with. He started getting into programming by writing scripts for the MUDs, but he refused to learn any other scripting or programming languages. Over the years I saw him implement a chess engine, a web server, and even a whole MUD all using his MUD client's integrated scripting language.
