LED chaos panel build. 54 independently flickering LEDs.

This is an update on a design I did decades ago where I made a PCB that fitted in a picture frame and allowed a matrix of LEDs to be installed for artistic or test reasons. I thought it would be worth updating the design with surface mount resistors, partly as practice for soldering them. I also wanted to test a reflow plate and see if it was possible to use traditional solder to "ball" pads before placing the SMD resistors and reflowing them. This PCB has many uses. I may get a batch made. To find the flickering LEDs on eBay try this search link:- https://www.ebay.com/sch/i.html?_from... Target price around $8 per 100.
