Simon wrote a post on his blog detailing his DIY PSU console assembly:
If I was going to build a power supply display add on, I decided to add some current limiting to it as well – but it had to be simple, cheap, and work with the panel meters. Yes you can get similar Ammeters on eBay they are more suited to the 10A range, where I want to measure 10’s to 100’s of milliamps.
And seeing as I’m designing something, I thought I’d also add a feature that a lot of current limited (at least at the low end) miss – a method of adjusting the current limit *WITHOUT* having to short your rails.
