Semi-OT: I wish someone would make flexible building blocks for fastening/connecting such parts, i.e. something like Lego or Fischertechnik but better suited for electronics. Many people use 3D printers, but they seem wasteful for printing temporary cases for such projects. Wood is a possibility, but not so quick to work on. There has to be something better than duck tape and rubber bands...

There are already lego raspberry pi boxes. They are sold for less than $5.

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.

Third take: you use the free time to work on your projects and come out of lockdown stronger, healthier, and richer both in money and culture.

Most important point during a world pandemic is to survive during a lockdown.

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.

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.

Early summer was strange. I finished watching seasons one through four of the expanse on Amazon.com

Kept getting side tracked because it takes a dystopian science fiction set hundreds of years in the future to discuss basic income and climate change in television.

They're not very flexible though, I can't just take any accessories like the display in the article and attach it properly with a few extra blocks.

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...)

You need to do that 7 days a week? Did you do that before the pandemic as well?

I assume you'd go out and meet some people? Sports? Other out-of-house activities, that's all time you can use as "you" time now.

Reminds me of the first atomic clock wristwatch: http://leapsecond.com/pages/atomic-bill/ > Batteries are included (they last about 45 minutes but are rechargeable)

Supposedly, that retails for about $30,000.

Depending on your tolerance for accuracy, rubidium standards are much cheaper and smaller. Obviously the second is defined in terms of cesium, so if you really want to be the reference clock for your entire country, you're going to need to shell out the cash for a cesium standard. But if you merely want to be within a nanosecond per day, rubidium is fine for that.

Well, you can. You just need to attach the accessory to a lego piece that suits your fancy, and you're done.

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.

I'm honestly struggling with finding more time to do stuff and I don't have any kids.

I have loads of side projects I want to work on, loads of games I want to play, books I want to read, movies and tv shows I want to watch and I have a relationship takes up a lot of my time.

I was doing Adventure of Code this year and I haven't managed to finish the last 7 days because I haven't had time for it yet.

Though I strongly believe that if I was single, it would be a very different story and I'd be very bored and restless with all this time. Maybe the relationship is the biggest difference.

These 240x240 IPS displays are awesome and dirt-cheap. The best "application" I've seen for them is a tiny retro game console [1]. [1] https://www.funkey-project.com/

Love the concept of that but you'd have to have children's hands to play it. I can only see frustration and the thing being thrown across the room if I had one.

You can probably do this off an esp32 without too much trouble.

Please educate me on where I should go for esp32?

You can get those on banggood and aliexpress for incredibly cheap as well. You can look into nordic stuff as well for bluetooth related microboards to develop on.

If you're just starting out I can recommend looking at m5 which has nice little kits to get started. It's a bit pricier though. https://m5stack.com
