Punched paper tape

I decided to make a scalable LED panel, so a grid of LEDs, all full RGB (WS2812).

I can manage this at 2x2mm, using 1x1mm LEDs, but no space for decoupling caps or vias, or well, a lot, so can be stacked one way but not the other...

The alternative LEDs I am using, instead of 1x1mm LEDs, are 1.5mmx1.6mm. These are way better, lower profile, and do not get knocked off the PCB.

So spacing at 2.5mm grid is just about possible.

But in honour of my ASR33 teletype, the latest LED strip designs are like this...

This is 2.54mm spaced, 30x9 full RGB LED block. So can be stacked to make longer strips.

This is the exact size of punched paper tape, all 0.1" spaced stuff.

The 0201 caps are in-between, which is neat.

So, this may be on Tindie soon, if they work...
