Human: Compatible with `HP DPS-750RB A` Server Power Supply. It will likely work on most HP power supplies that have built-in fans. Useful for charging LiPo batteries or anywhere you need up to 750 watts of 12v power! To assemble, short the first and fourth pads from the left with a switch. The two large pads will then provide ~12.3 volts. Use a zip tie to secure the large wires to the metal frame to prevent the solder joints from breaking if they get pulled. ### Parts - [Rocker Switch](https://www.amazon.com/gp/product/B01MUJ9K5R/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1) I purchased this one from Amazon. - LED Any 5mm LED will work. I used a white LED and a 680ohm resistor. Any resistor between 220 and 800ohms should work. If you want to be precise, [calculate the required resistor here](http://led.linear1.org/1led.wiz). The screw is just a standard hard drive screw. I used a washer since the screw was a little bit too long. ### Versions 2.0 - Redesigned to allow for air flow 1.0 - Initial design (deleted because it would overheat)
