Easy to build lab power supply from cheap eBay parts.

What you will need:

  • Power Supply unit: eBay Search
  • Spare laptop power supply (I use one with 19.5V DC / 4.9A)
  • Some black/red/yellow wires (from old PC power supply)
  • Female banana panel plugs: eBay Search
  • On/off panel switch: eBay Search
  • 4pcs 3x15mm countersink self-threading screws.
  • Printed case (this model).
  • Solder iron.

Note: Max. output voltage is limited to input voltage - 0.5V. Using the suggested laptop power supply will give a max. output of 19V.

Great for metal plating as it has the fine control for current needed for best result.

Follow photos for assembly.

Model shown is printed in Devil Design grey PET.

Updates
2021.01.29: Added model with ventilation slots for high power modules.
