I'm running my credit card close to the edge (my definition = barely enough in the checking account to pay it off) but payday is tomorrow, I have several projects to work on, and I've had it with the cheap bench power supply that I have. I went ahead and ordered the Korad programmable bench supply. At least I will be able to set a voltage properly. The USB interface seems interesting. Writing an interface for it might be a cool reason to learn Python or something.
