A Pixel Purse LED Cube Controlled by a Cisco 3G Modem

Tom at Electronics etc… posts about using the inexpensive pixel panels in the Pixel Purse to make an LED cube controlled by a Cisco 3G Modem. If you aren’t familiar with LED cubes, here is a post by Bob Miller that provides some history and implementation information.

I always wanted to do something with LED panels myself, but there wasn’t a catalyst until October 2019, when the Pixel Purse went on sale on Amazon for $6.16. (As I write this, the price is back at $52.)

I wondered if I could make an LED cube by using my reverse engineered Cisco HWIC-3G-CMDA modem as LED panel driver?

In the end, … the overall lesson is clear: Don’t commit to a conference talk with an unrealised idea!
