Talk:Open Source Benchtop Power Supply

An advantage of such opensource instruments over buying a used proprietary instrument on ebay or whatever, is with proprietary instruments usually communications ports (e.g. RS232, USB, ethernet, GPIB, CAN bus) are all usually optional add-ons for additional cost at manufacture (non-standard), and such an instrument might not have any means of interface with a computer. And if they do, their functionality may be limited:

  • e.g. only telemetry available is what is currently displayed on the display panel of the device
    • e.g. only voltage measurement not current unless button is pressed to measure current, or annoying remote mode toggled
  • and at e.g. only 1Hz vs 4-60Hz readings. Aside from accuracy specifications, there is a difference between models/brands in how many times per second you're able to get a measurement.

There are also often other optional features available for additional cost at manufacture/order time. There is a lot of functionality lacking in the cheaper ($400ish programmable DC power supply $400ish programmable DMM) proprietary models (both new and used) in comparison with more expensive models.

Those are I think lesser known advantages, not immediately obvious to someone not well-versed with such instruments, so I mention them here. There are of course other invaluable advantages with open source hardware and software.

For electronics development I think the EEZ Studio is really top notch, for running experiments, automatically recording results, etc. Typically labs make their own in-house means of achieving such work.

I barely know anything on the topic short of basic circuits, logic gates, and that AC power is like...a thing. So PLEASE feel free to go over all these bits and fill in the various blank areas, or correct/clarify the things that i may have put down.

Also maybe even make a page on the EEZ stuff, and maybe try and figure out how to mill/etch them with the D3D PCB Mill or some sort of other PCB Production Workflow

Also you can check out OCI and This kind of placeholder construction set for electronics pages.

Don't want to come across as "DO ALL THESE THINGS RAAAAAAAA", but it is great to have an electronics person around, and i look foreward to seeing what else you can add to the wiki's knowledge !
