I needed these to run an old BLDC motor I scavenged from a dead hard disk.

All of it melted the next day. It's been raining since then.

One tube to rule them all.

Now with 3 LED drivers and no P-MOSFETS anymore. Color balance can now be adjusted in hardware. I'm using 6/6 for signals, 6/8 for the LEDs and 6/16 for power.

This is a prototype for the next version of the RGB LED RING project I have been pursuing for some time now. I will try to get away with just one LED driver chip and do the color balancing in software. If it doesn't work out I can either try to add 3 of those or switch to a TLC5947 (24ch, internal dot correction). As it started to snow today, I changed the color theme accordingly and added some silkscreen 'art' as well.

Now fully assembled. Works ok for me up to 100MHz + RLE. 200MHz sampling rate + RLE needs stronger pull-down resistors. With RLE turned off the 'noise' on unused channels creeping over from a used one is tolerable (for me at least).
