Open-Source-Power-Supply

An open source benchtop power supply that's good enough for most purposes.

The case was 3D printed using a Monoprice Select Mini with wood PLA for the front and back panels and green PLA for the top and bottom parts of the case.

The 3D designs were generated using Heartman's Ultimate Box Maker and Steve Colley's Parametric Potentiometer Knob.

Characteristics

• Input Voltage: Up to 19V without fan
• Output Voltage: 0-12V
• Output Current: 0-600mA (see Note)
• Adjustable current limit

Note: Current can go up to 800mA by replacing the five 10 Ohm resistors with five 5 Ohm resistors. One should also double the gain of the differential amplifier in this case, so as to display voltage and current correctly.
