preenfm2 and preenfm3 / Adding Power & USB switches to metal case?
« on: January 27, 2020, 12:13:33 PM »
Hi,
Just finished building my Preen FM2 (did my absolute best to mess up the build by using my own IC socket which only had space for turned pins because I am an idiot, but managed to recover that!)
I'm thinking of adding a switch for the USB power jumper, because in my main studio set up anything on USB power seems to be involved in a hideous ground loop that I am struggling to overcome, but it would be great to power it via USB when working with my laptop elsewhere.
While I am at it, I guess I might as well add a power switch if there's space, which leads me to my question:
Has anyone added such switches to a metal case and if so, where did you find the best space to do so? It's quite hard to visualise from outside the case....
