Hello. I just finished my first CMoy using tangent's very clear instructions. I've been listening to it uncased, and it sounds great. Now I'd like to throw it in a case and have something a little less exposed. I'd like to ask a few questions on some casing details I haven't found any discussions on.
1. The LED. How is it "mounted"? Drill a likely-sized hole and stick it out from the inside? Feed the leads through from the outside? What keeps it in place? And by the way, what gauge do you guys normally use for this sort of thing? The (22 gauge?) wire I'm using from the Radio Shack jumper wire set is quite stiff and doesn't like to flex.
2. Grounding. Tangent's notes on grounding indicate that if you're wiring panel elements that ground to different levels in a metal enclosure, you're going to need to insulate one set. What's the easiest way to do this? I've read about insulating washers (where can I get these?), and using electrical tape (really? how is that done?). What's the best way to keep the solder joints and snipped leads on the bottom from grounding against the case? Can I just use paper, or is there something more suitable?
3. DC power. I'm planning to put in a DC power jack at some point using the diode OR bridge. Would it be safe to use this method to connect 8 NiMH AAs, or is that dangerous (AA voltage could drop below the 9V cutoff point)? Also, the original Cmoy article mentions wiring up a cable for an 8 AA battery holder, and he uses a third wire grounded on the case side but not connected on the battery pack as a "shield" wire. What function does that serve? Also, has anyone here designed a DC-DC converter circuit to run a Cmoy off AAs?
Any help greatly appreciated.
