DIY - Constant current sink - Active Load

#13 It took a while to finish, I started to work on this in the summer, and now it feels like winter outside, but the constant current sink is finally done.
In this video I recycle an old heat sink and turn it into a piece of laboratory equipment - a DIY active load. Of course the circuit can be improved and enhanced, but I just wanted to make something simple and bare-boned.
