FreeRTOS was previously GPLv2 with a couple of added clauses (anything linked with FreeRTOS is now GPL too and you can't publish performance metrics without approval). I'd imagine there were a lot of companies not wanting to GPL everything they made with FreeRTOS (i.e. Amazon) so with a new MIT license, anyone can do whatever they want.

So they somehow took over a free software project and removed the GPL? That doesn't seem like a positive development!

And assuming they didn't merge their fork back in, the original FreeRTOS codebase doesn't get any of their fixes/improvements either.

What a great project! I love how much attention to detail he put in. Fantastic, this is exactly the kind of thing I love studying and working on myself. Sidenote, I'm a bit disappointed that people use imgur to showcase their projects, as I don't think it's very good for that. I built https://www.makerfol.io/ for this exact purpose but people seem to still prefer imgur for some reason, and I'm not sure why :/

Just a heads up but your terms and conditions link doesn't work

I am wearing one right now and it’s amazing - Especially it’s battery life (easily 1 month+). I get loads of compliments about this watch. The feature set is just enough for my needs, even though I considered getting an Apple Watch. The app is also more than decent.

Yup, same. I love that i have to charge it once every 3 weeks, tracks my bike rides while i commute to work, runs and workouts. People usually don't believe that it's a smart watch and more surprised when i say that it's Nokia. I usually get the reaction "They are still relevant"

I currently use a Fossil Explorist, but I'm pretty frustrated by the battery life, and honestly it's just... slow. I'm curious to hear your thoughts on run tracking - I don't want to carry my phone with me, and it's really nice to have my watch track distance via gps.

Oh oops, thanks for letting me know! I'll fix that ASAP.

yeah very impressive. Is this how products are really prototyped? I feel he could have mentioned either 20 years of experience in all parts of this field (if that's how come he could do it so cleanly) or if he did actual prototyping steps he could have mentioned them or showed some pictures. From the pictures, it comes off as something anyone can do in a week or two. like building a table.

Maybe I'm wrong and the pictures do do the process justice?

Either way definitely amazing.

Right now they're very gimmicky, Apple watch has a much better app ecosystem

I own an Apple Watch and have yet to find any apps I'd use for it - I currently use it entirely for telling the time and for notifications (and for the record am quite happy with it!). Any watch apps you can recommend?

I have the 4. I regularly use it for most of my music listening (when travelling or working out + bluetooth headphones), Transit tracking apps (here in Toronto I use RocketMan for the most part), use the NHL app to follow scores if I'm not watching the game (not often now that the Leafs... did what the Leafs do...), Maps (on occasion), and news apps—Apple News, News360, and AP. Oh, and the Weather Network app which can also feed a live temp. reading to the watch face (handy in the winter, especially).

Personally the biggest boon for me is workout tracking and health data. It's transformed me over the last six months or so (girlfriend said it changed my life—though that is a bit extreme).

There's even a VO2 max estimate if you track a run or walk outdoors for more than 20 minutes.

Actually I just use it for many of the things I use my phone for except for writing long messages, email, or web browsing. Which is kind of nice. I put my phone in my bag and forget about it most of the time when I'm on the move. It's been good that way.

So I'll end there because I'm sounding like a sales pitch. I wouldn't push anyone hard to get one, but for me it's been fantastic.

Edit: For anyone else reading this comment, my biggest complaint would be battery life. I won't get more than 2 days out of it without charging because I use the battery-intensive heart rate and music functions regularly. Resolved of course by charging it nightly beside my phone.

The physical assembly would likely be a week if you're following instructions and avoiding other people's mistakes.

The person who made it probably made a lot of mistakes that you're not seeing, and is used to working at this level of quality.

You could imagine this whole thing started on a breadboard and IDE at some point, but the final assembly is "print the things that I drew on the computer, glue and screw together".

It's interesting to know how one can build the one thing for about ~$80 even in small quantities, and everything is available, incl Source.

If people started selling the pre-soldered board as a smart-watch starter kit on Aliexpress , pretty sure someone would buy it.

This is the sort of thing that would make DIY popular, I can see why.
