Evolution of the flame effect LED lamp. (simplified schematic)

It's over a year since I made a video about the new flame lamp effect that was appearing on the market. It's evolved in an interesting manner. Better visual effect and a modular approach that allows adaptation to battery operation. The circuitry has been simplified too and has quite a neat trick to allow the driving of 99 LEDs from a low pin count processor. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
