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.

#62These 240x240 IPS displays are awesome and dirt-cheap. The best "application" I've seen for them is a tiny retro game console [1].

#63where would I get the display for 2 USD?

#64There'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 have one in an IT little closet at home that displays a few stats. Temperatures, line speed, my public IP, a few PiHole stats, NAS storage space, etc.
Another screen shows a few values from temp and humidity sensors that some esp chips are collecting.

Originally I was just using it to display the IP addresses after reboot on a smaller 0.96" 80x160. Then a screen shot... then zoom. I'm thinking more about some QR code with basic sysinfo.
QR for status or info on anything is the winner here... can you array these off a single PI? Imagine this: An installation where there is an array of these screens - they are associated with whatever you want info on - they cycle btwn a screenshot of the item, some basic text (like IP/UPC/Barcode/QR to a fully detailed product/item page, uptime/health status...) etc... And you can just have a PI running a bunch of th…
You can probably do this off an esp32 without too much trouble.

#66A 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.
Don't you need time alone with your significant other? That's the only time we've got together, so it's difficult to find "me" time, as I also need to care for my relationship (not that it bothers me! But 24h are 24h...)

Super agree. Its either "I'm bored out of my wits" or "i'm exhausted with my kids" Folks with more time and energy on their hands have managed spend it all on a broad variety of rabbit holes. Folks with kids have managed to wither whatever minutes were left away, looking at the other group's reports on their rabbit hole expeditions Both, together have managed to give google enough confidence to double their ads and d…
> Both, together have managed to give google enough confidence to double their ads and disable the "skip ad" buttons on youtube. I'm finding that I'm not using youtube that much anymore. It wasn't really a conscious decision - the annoyance pushed away my reptilian brain.
I barely use it on my phone anymore and on my desktop I installed an adblocker again (before I only used uMatrix).
But we’re a minority, obviously Google’s choice is paying off.

I don't have kids and I don't think I've gotten bored once - I had the time to watch a whopping two TV shows this year.

4, 3 and a 1 y/o for me. Can agree, that it's been hard to maintain the same focus and energy recently.
We feel like the worst parents in the world because our kids apparently don't need as much sleep as other kids. We've tried extensive bedtime rituals, tried tiring them out by going to the forest and making em run etc, but we really can't get our 1,5 year old to need more sleep than we do. Our 4 year old tends to sleep an hour longer in the morning, but the little one is really killing us from a freetime standpoint w…
Oof. That’s tough. I’m sure it’ll get better, but it’s definitely hard work in the meantime. Just keep in mind that it’s temporary on all counts.

#70You may think this is "tiny", but I got a lot done on my Apple ][ back in 1978 with a 280x192 pixel display.
You’re 280x192 pixel display was probably 13” or even larger. This display is 1”x1”. You can get about six lines of 12-15 characters on it if you want to be able to read it from further than 6” away.
You should watch the movie Brazil, if you haven't. All the computers have tiny 2" displays, with a Fresnel lens attached in front of it
