Check out this simple kit offered by Eric Thompson’s Low Voltage Labs:

This year at the Seattle and Portland Mini Maker Faires I did a presentation on getting started with designing your own PCB using KiCAD. In this presentation as an example I created a pumpkin shaped PCB with a candle-like flickering LED. I’m releasing the KiCAD schematic and PCB layout files to use as the starting point for your own project.

You can also buy the kit from Eric’s store. Great for putting into punkins in place of a candle!

  1. Can someone please explain to me how this circuit causes the LED to flicker? I am new to electronics and can’t figure it out purely from looking at the schematics. Is it a special kind of LED?
