These look a lot like our NeoPixel fairy lights here, but have a funky twist. In fact, we're a little hesitant to call them NeoPixels because while they can be controlled by "NeoPixel" code, they don't function like NeoPixels . Technically, an NeoPixel is an LED that also acts as a shift register. 24 or 32 bits of brightness data comes in the input pin, and the LED removes it and passes along the rest. This is what lets folks...

These pretty circles of light are plastic diffused backlights, probably originally used in LCD gauge displays. Normally they're tucked behind the LCD and shine white light from below. Here, we've got the LEDs available individually, and they're really cool! Each LED is encased in a 2.2mm thick semi-circle of acrylic. The acrylic is a special type that is very good at diffusing light, so even though there are only two white LEDs,...

Back in my day, if you wanted to make a mechanical keyboard, you had to solder in expensive Cherry MX switches onto your PCB - and woe to the person who decided they wanted to change their linear keys instead of clicky ones!
