Cylon circuit close up
Okay, it's a mess. But, it's a quick and easy mess!
This is for a vintage Cylon's scanning eye; Learn how to build it here.
1. One of the capacitors is a different color. I don't know why. The specifications are identical to the other five (all 47 uF, 16 V). I harvested all six from a DVD-ROM player that I disassembled. =)
2. I like to stand diodes and resistors on end (a habit acquired from years of building tiny circuits), so it's a little hard to see those ten little diodes. But, they are there.
3. I used an NE555 timer. It's better to use a 7555 timer instead, which is nearly identical but doesn't waste nearly as much power.
