LED matrices are so fun to play with. The low resolution and chunky pixels give them the aesthetics I really enjoy.

I’ve built a 64x64 pixel art frame [0]. With the diffuser in front of the matrix, it looks like animations are floating in the air. I got parts for v2, but I’m yet to find time to build it.

I really like how electronics today are very accessible to start playing with. Basic stuff is mostly plug-and-play, and essentially it becomes a software project.

Classic project I want to do but know I’ll never make the time for lol that’s really cool man. Saving this on the off chance I one day get off my rear for it

Hehe I know what you mean. I mentioned I have parts for v2 (stronger controller, rotary encoder with a big brass knob and completely offline - hardware real time clock), but we’ll see if it will ever happen.

Projects like this are always interesting to me because it is fairly outside of my skill set, but I feel like I could get there ha. We’ll see!

I'm amazed at how cheap the LED matrix listed in the parts list is. About a third of a cent per LED, not even counting the rest of the hardware! Wow.

At €20 per 32x8 module (2000/256), that's €0.078 per LED which is considerably more expensive than a third of a eurocent, I think? Even if it was €20 for all 6 panels, that's still over a eurocent per LED (2000/1536).

Cheaper now - AliExpress will sell you 6 32x8 boards for £59.21 (3.85p per LED or ¢5.16 if you're a colonial) saving you ~€52 over the original €120 price.

Technically it would depend on the colony.

The US, Canada, Australia and New Zealand are all ex colonies and all use the cent. I'm sure there are a few more, we did get around a bit.

Fair point. I keep forgetting how many people have weird currencies outside of Merkia.

I bought something like that for a birthday gift, €15 all in all, comes with USB for power and an app / bluetooth for programming it. It was really well received!
