Long time ago, I wanted to make my own LED cube - mainly because I had an interesting idea of what to show on them. Sadly, I never started building it because of the huge amount of work that comes with soldering hundreds of LEDs together, bending each leg such that it can connect with the next, then adding even more wires to be able to create a multiplexing grid. Plus tons of logic, power switches and current sources to drive them all. And I wasn't even daring to dream of full color RGB...
Then came Worldsemi and made LED's smart.
I just started experimenting with some NeoPixel rings, when suddenly my old idea came back into my mind. But I didn't want to design yet another LED cube. My goals are:
- (almost) invisible power and signal wiring of 8x8x8 full RGB dimmable LED's
- easy to assemble (I estimate 2-4 hours - no soldering needed)
- lowest possible cost (full kit will proably around 150 .. 200€)
- open source hardware and software for
your cool ideas (STM32 based, Bluetooth, USB?)
- ability to immerse the LED arrangement in de-ionized water to reduce refractions of inner transparent structures
- plus some new features that are related to my untold idea above
That was two days ago, and the overall construction is finished and ordered. I have some first rendered pictures (can't wait how that will look in reality) and am eager to read your comments
