DIY Notes

While extremely useful, no single decent open source design exists for an Arduino-driven, switch mode, offline power supply converting to 12 or 24 volts. There is a number of examples of complicated switching in DC-DC, but nothing for 120AC to 24VDC supply such as for a 3D printer (250W) or a small welder (2kW) - which could both be very powerful, useful use cases.

Closest Examples

  • None

SMPS Diagrams

  • Simple low power - 12W - [1]

DIY BOM

  • High frequency transformer - [2]
  • $10 for a 500W transformer - [3]
  • $6 for 100W - [4]

Regular

Mini

  • 6A - $11 - [9]
  • 5A black - but need to splice in another cable - $14 - [10]
  • 24V 3A $5 - [11]
  • 24V 4.2A - $12 - [12]
  • 24V 5A - 120W - $15 - [13]
  • 24V 4A review - 3week ship for $7 -
