Your litany of disasters with approved stuff makes me feel even better about buying unapproved stuff, especially if I can get it really cheap.Not sure that was the intent....
I wonder to what extent I cooked the mineral oil and the compressor - it was way too hot to touch.
I would call it irony, but lefty would probably call it sarcasm, and who knows what doc.e would call it.
mineral oil ...
Hey lefty that is a nice looking board. Look forward to hearing how it performs. Limiting the current that is fed into the arduino is one way to limit its magic smoke potential?
Well I'm anxiously awaiting the arrival of my new Arduino power supply, sans any UL approval or not.
a supply like this should not be called a constant voltage/constant current supply but rather a constant voltage supply with an adjustable current limit
mineral oil ... Most refrigeration systems use oil to keep the compressor lubricated.
