Meet Newman, my new rear bike light.

Compliments of Colin Pringle, I adapted this circuit to make a dual LED rear bike light out of a mint tin:












I did have to improvise a bit on Colin's circuit as I only had certain things available in my junk drawer(s). R1 and R2 are both 1k ohm resistors and I switched R3 and R4 to be 680 ohm resistors. The lights blink 180 degrees out of phase from one another.

Here is the finished Newman:

















And the inside:


















It's good to be posting again. This little guy took about an hour. This is just the beginning, time to start doing more.
