retrolefty:
I used 20 1,000 1% resistors ordered on E-bay for just a couple of bucks.
I initially read that "I used 20,000 resistors". Wow, I thought, you have a lot more patience than me!
Interesting article, thanks.
BTW, when measuring the AC component of the dummy load it seems quite high (a few hundred millivolts) when the MOSFET kicks in, at least at the "edge" point. Would you recommend a capacitor somewhere to smooth that out? If so, what one and where?
