A hot mid day and chance of thunderstorms tonight prompted me to head down to Study Butte for some refrigerant. Home at the Field Lab by 2PM and plugged in the soldering iron. Took about and hour and a half to lay all the parts out then fix them on the circuit board. Haven't lost my touch. Dug up some parts to wire it up and put it to some testing on the Pepino pump. Good news is it works just right. Now I just have to tweak the potentiometers to dial in the best on and off times to circulate the right amount of water to give me the lowest temperature out of the unit. A couple of thunderstorm zoomed right north of me with just a few drops on my dry lot.
