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.
- 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.
