LOLwut? NeoPixels in through-hole variety? Oh yes, we haz them! If you like NeoPixel strips you'll luv these 8mm diffused through-hole NeoPixels. All the single-pin-controlling-hundreds-of-LEDs goodness in a breadboard friendly format. Each LED looks just like your classic through-hole 8mm...

Deprecation Warning: The Trinket bit-bang USB technique it uses doesn't work as well as it did in 2014, many modern computers won't work well. So while we still carry the Trinket so that people can maintain some older projects, we no longer recommend it.

Wow, is this not the most useful thing you did not know existed or what? It's a switching wall adapter where you can easily change the voltage! It's like a benchtop supply you can take with you anywhere.This model is 10 Watts and has 6 selectable outputs ranging from 3V to...
