    Can his solution “hacked” to turn it into a constant current source? Just out of curiosity.

    Heat sink part was really good. I was just buying a small and simple heat sink and hoping it would work. :D

    Hi,
    Just wondering, how can I use the dummy load you created to test a negative power supply?
    Thanks!
