There's a lotta cool/interesting applications for a tiny display like that. Thanks for sharing. :).

Other than watch-like functions, can you give me some ideas?

I used a similar screen to display the user interface for my DIY reflow oven. The raspberry Pi and Linux is overkill for this project, but it's so much easier building a GUI than on a microcontroller.

Reminds me of the first atomic clock wristwatch:

Supposedly, that retails for about $30,000.

I want to make a smart glass like device with a tiny display or a projector, Raspberry Pi Zero as the main board and powered by a battery pack. Does any one have any input regarding optics?

Just thinking about the possibility of having a linux machine always on you seems really exciing.

A bit off-topic but related to the intro in this readme..

> Why? > I'm super bored in lockdown. Add a Raspberry Pi 400 and a few tiny displays...

I feel like there are two distinct kinds of lockdown experience. One, you have kids, and you have absolutely no free time because now your kids are home and you're working from home. Two, you don't have kids, and you're super bored every day. Seems like not much in between.

they don't go to bed? I work in my garage workshop from bedtime to midnight or one a few times a week. I've turned out way more finished projects than I ever did before the pandemic.

I have a 3yo and a 10 month old. Way too tired for that.

Maybe if they were a bit older?

4, 3 and a 1 y/o for me. Can agree, that it's been hard to maintain the same focus and energy recently.

Kindergarten? School?

At least in Norway the government has focused on locking down old -> young. So bars and restaurants and gyms are pretty much shut down, put kindergarten and primary schools are still open with some restrictions.

Mind you though. Most of the people I know with small kids didn’t have much time to spend on side projects before the lockdown either. Only difference now is that they save an hour of travel a day.

Maybe this would be a place to start.
