In winter holidays we decided to work on our dummy load.

We posted some pictures of the design and the completed device.

I was inspired by Dave Jones blog about making a simple dummy load for testing stuff (power supplies, batteries, etc.) ...


Holy thread resurrection, Batman!

Thanks for the circuit, Nick. I'm going to build it -- except I'm going for higher wattage. How much? Well, that'll depend on the what the landlord has on hand to donate -- maybe a couple big mosfets in parallel. He sure enjoys giving me stuff for my projects. :) At most, I shouldn't have to buy anything but big heatsinks.

Well, I finally finished building my version of this. Scaled it up some. Isn't working. I've stared at it for a while, and can't find any solder bridges, bad connections, or mis-wiring -- doesn't mean there are none. Given that it's off-topic, does anyone have any experience with:

as being good/bad?

Or, if folks are up for it, I can post the circuit, and description of the symptoms.
