What's on your workbench?
#12
A high current dummy load for testing power supplies. No circuit diagram required it's that simple.  I used four halogen globes that I can switch individually which means I can increase the current in 9 amp steps. A cheap eBay volt/amp meter with current shunt and a couple of cooling fans all built into a old PC power supply. You don't often need to do this to a power supply, but when you do, a load like this makes it easy.

These Manson clones just keep on going. Who has ever seen their power supply do that for a prolonged period of time?
