another high power dummy-load

[nmbusa]

Hi

thought I make a comeback after a couple of years absence from lasers from the time tearing down cdr/dvdr to extract diodes.
made a high power dummy-load for NUBM44 handheld project
used mur1560 15A diodes I had lying around and 2 Caddock Surface Mount Power resistors 0.2ohm 25W in parallel.
cheers

Congratulations on your test load. I would have used more diodes as the forward voltage of some diodes are higher than you can get using just 7 of them. But, even with 7 it should work fine just for setting the current alone on your drivers.

yep your right have another 3A 10 diode from back in the day for higher Vf diodes
