  • After a month of continous use the unit is working great. Created a small solar charged battery powered electic fence charger. Used a 3.3 volt Sparkfun Arduino Pro mini with a FET soldered direct to pin 3 and ground running the blink led sketch. Solar panel keeps the 6 ah Lipo battery charged. This will not power miles of fence but works great for spot applications.

    Cows ate all the wires off my trailers so ran a small loop of electric fence around it and no more problems. Has high voltage but low amps. Hurts but does not seem to injure cows or people (me).

No public wish lists :(
