Here’s a cool blending night DIY, very simple and easy to do with your Picaxe. Picaxe is a very
cheap microcontroller you can do a lot of cool stuff like this…
had a few multicolor LEDs laying around and wanted to whip up a color-blending nightlight. I built 2 devices, each in its own 20 pin DIP socket without soldering. A 3-pin header is included so I can reprogram the light on-the-fly if desired. On my first build, I used wire-wrap. The next one used multiple wires pushed into the socket. A bit more difficult, but no wire-wrapping or soldering necessary.
