Happy Easter!

I attempted to create an egg circuit. It kinda worked. I used a Circuit Writer pen and less-than-patiently let that dry for hours. Then I painstakingly soldered the LEDs and the wire.

Some notes:

  • Paint the circuit the day before Easter, so that it dries and becomes more conductive.
  • Use thinner lines. There’s a lot of resistance from the pen (though, I didn’t actually let it cure fully)
  • Don’t bother with resistors. The red wire was supposed to be a resistor, but the lines provide plenty of resistance to avoid burning the LEDs.
  • Let the egg get to room temperature before writing on it. It took longer to dry and the ink had a field day running down the sides of the egg.

That’s the best I can do this year. Maybe next year I’ll try again.
