Hi!

I`m Looking for good (i.e. stable and rugged) simple (since I`m 60 years old tech, not an engineer) DIY project of Electronic Load
No mc`s, only discrete transistors and some opams -- I hope to build it from my basement scrap  :-DD

it would be nice that I could modify the circuit for different voltages and currents


Can You recommend one please?

This project looks good, seems to match your requirements:

Jay’s load (link in previous message) fits the description perfectly. I’ve built one and I’m pretty happy with it.
MarkF:
The thing I don't like about Jay's Dynamic Load is that you need a dual power supply.  I built something similar to Dave's Dummy Load



and Peter Oakes Load



that only requires a single +12V supply.  I set my max current at 1.5A but with a change in the sense resistor to 0.1 ohm and a very large heat sink and fan you could go to 5A.

This is what I did:

Thank You!

But   IXYS are WERY expencive units!  :o I have no one in my basement junk  :-//
Can I use some common MOSFETs?
