Grids with Make Noise Shared System power?

Did you try this? Worked for me.

2015 grid noise fix

some 2015 grid users have reported a high pitched noise coming from the grid when lots (and lots) of LEDs are lit up. i’ve identified the problem and a simple fix-- the problem is that in these new builds, the type of capacitor was incorrect. two ceramic capacitors were placed by the boardhouse instead of tantalum. we didn’t catch this error during inspection as the grids function perfectly well-- but for the sake of making these grids more perfect, here’s what needs to be done to reduce the pot…

Hey, no I haven’t tried that. Hadn’t spotted it was an option. I’d be very cautious of attempting this, however simple it may be. It would be the first soldering I’d ever done on a serious piece of electronic equipment.

Would be a hell of a time to find out I sucked at it!

Reviving an old thread here! I’ve got a 2014 shared system with CV bus that I’m hoping to use a couple of the trilogy modules with, but I can’t figure out conclusively whether it has the newer power supply. It definitely provides 5v – the 5v led illuminates when plugged in. I’ve tested it briefly in the past with an Earthsea and a grid plugged, albeit not for very long. The stories of it working for a while and then melting to the ground have me spooked!
