Bench power supply

A Sparkfun bench top power board kit let me take a 300 W power supply salvaged from a dead computer and use it as a bench power supply.

It’s a handy little kit that takes the power supply motherboard connection and breaks out the +12V, -12V, 5V and 3.3V DC to fused 5 way binding posts.

According to the label on the power supply, it can source 17A at +12V, 0.2A at -12V, 19A at 3.3V, and 15A at 5V. That should be more than enough for any projects I’ll run off it.

I also picked up a few of these simple little 3-digit voltmeters that I’ll connect across the outputs to show the voltages.

Next will be to figure  out an enclosure to contain everything.
