Miller Engine Solar Popper

solar light tracker

details coming soon thanks to noise0 for his Paco 


This is basically a light tracker using 2 x Miller SE and 2 x LDR.


I used the Paco circuit but replaced it with a Miller solar engine. Its not the best design but it does work well in the sun. 



Any comments are appreciated!

Nice job. He looks like a little hermit crab and he tracks light well. What flavor of 1381 did you use?

they are 2 x 1381C which triggers around 2V - 2.2V

I got them from Solarbotics. Couldnt find them anywhere else for cheap :)
