MOTM

I had thought about paying for a silkscreen, and spreading the cost around
to whomever else is interested. You'd buy blank panels from Paul, drill
them, and send them to me for the screening. I'm not near as ambitious as to
build my own screen - I'd probably just go to a tshirt company with a design
on a floppy and have them make the screen. If anyone else that wants to
volunteer, speak up - I'm more than happy to hand them the ball. We would
all just need to agree on the panel design.

There are some other issues as well. Blacet's pots and the pushbutton switch
in the kit are too short to mount through the thick MOTM panel. You won't
have any threads left to screw a nut on. Also, you can't mount the pots
directly to the pcb if you want MOTM pot spacing on the panel (I do.) Third,
the DarkStar pcb does not have mounting holes to mount to the MOTM pcb
bracket.

I'm using different pots and switches with longer collars, mounting the pots
off board with twisted wire ala normal MOTM procedures, and drilling holes
in the pcb for mounting it securely to the bracket. I'll use nylon standoffs
and bolts since I will be near other traces.

On the good side, the MOTM panel form factor allows for 2 more jacks than
are present on the standard DarkStar, which I'll use to add VC inputs for
Attack and Decay (just need to add 1 resistor per jack to the pcb).
