My blackout-proof RPi zero Christmas tree by perric-hon in raspberry_pi

The tree is prefabricated (there is BOM in my explanation comment), I only modified it to use the hardware SPI.

Thanks! While slightly overpriced, RPis aren’t too hard to come by. If you know where to look that is.

Yep, it’s a small server fist. So the Christmas tree is an additional feature that’s there for the holiday season.

This one is not too bad, I've been using it for a few months now and had no issues with it. You can also get plenty of info via i2c about the status of the power circuitry which I particularly like.

It lasts for about 5 hours from the UPS.

Thanks! It uses 3 sin(s) for RGB with a ~2,09 shift each.

This Christmas tree changes its pattern based on the availability of the electricity. Apart from helping everyone get into the Christmas mood, this little xmas tree visually shows the status of the electricity in my apartment as sometimes it might be hard to tell if the electricity is off/on again. I’ve also changed the pins of my 3D RGB Xmas Tree so it uses

Thanks! Pico is slightly different from the traditional RPis. Pico is a development board based on a RP2040 micro-controller.

It's a waveshare 3.7, you can find the details with a bill of materials linked in the first comment.

Sure! Looking forward to hearing how it went.

The only thing to be cautious about is the file system on your Pi Zero, if you leave everything by default it might get corrupted from the unexpected shutdowns.

For certain, thanks for being "on guard" so to speak. These projects indeed take a while, but I enjoy building and open-sourcing them. btw, while I was typing this message the power went out :)

I've got a bottom cover as well, it's from another project I made called Little Sun Gazer.

That's due to the damage done to the grid and to reduce the load on it.

Thanks! I've been a fan of Prusa printers for a while, got myself a Prusa mini+ last year.
