Easiest low voltage cutoff (ensure minimum startup amperage for solar fan project.) Answered
So, if I weren't so electronically derped, I'd know this.
I've seen a few easy ideas for a 12v solar fan. Basically stick a capacitor on it.
However, I'm trying to work from a few low amperage panels (~100ma@12v total). Since I want this to keep my tent feeling cooler once the sun comes up, I don't want to be stuck for an hour or two in the morning until the minimum amperage comes out of the panels.
Anyone have an easy idea of what I could use with simple parts from scavenge boards or electronics teaching kits to make it have a low voltage cutoff (so that it won't go to the fan until it hits a minimum voltage on the capacitor (so that it has a minimum startup amperage)) That way, even in the morning, at least it would pulse on for small whiles even when it didn't have enough power.
