Hi Everyone,

I am designing my first module right now, a MIDI to CV convertor.

I was hoping to get some advice on what you guys tend to use for 3.5 mm jacks, DIN-5 jacks (MIDI) and what pot series you like to use for homebrew stuff.

Also, what shaft diameter? I'm am looking to set a standard for my stuff before I begin.

I am leaning towards edgemount (right angle) parts because they don't require matching heights for everything, and because the modules are easier to service if the boards aren't parallel with the panel.

I'll start off with a couple of mine:

50K trimmer pot, right angle, Philips: Bourns 3361S-1-503GLF

tact switch, right angle: E-Switch TL1105WF160Q

DIN 5 female, MIDI jack: CUI SDS-50J Not that great, but cheap-ish and works. I think Doepfer uses these too.

I don't really do mmuch panel mount stuff at work, which is why I am asking for advice.

Thanks!

I use either thonkiconn or Erthenvar 3.5mm vertical jacks, and 9mm Alpha pots. Thonkiconn and 9mm Alpha heightmatch pretty well.

I haven't had to use a DIN socket, though. Most robust solution would be to have a cutout in the PCB, and run short wires from the socket to the PCB (with the socket bolted to the panel.)

I like edgemount - but if you have a mix of pots, switches jacks etc you have the problem that though you can make them level with the panel surface, their centres will probably not line up. Which is just as bad..

On the subject of din sockets, be sure to leave enough hole in the panel, you would be suprised how fat the plastic around the plug can be & you might find some leads just won't go in. I used to manufacture a midi-cv converter & the PCB jacks felt pretty shitty - but the never failed, unlike the power jack which probably suffered from people trying to push non-matching wart plugs in Mad
