Subject: Re: [motm] Veeblefetzer panel options

From: Scott Juskiw <scott@...>

Many thanks to Larry for offering a panel with a bezel cutout. Here
is some additional info on the Veeblefetzer panel.

I've created an LED mounting board that is full of holes (with pads
but no traces). This board mounts 90 degrees to the motherboard using
a right angle 0.1" connector. You have several choices for LED
mounting.

1. You can drill holes in the panel wherever you want the LEDs to go,
poke the LEDs through the holes, then glue them onto the back of the
panel (like we all did with our original MiniWaves). This option
ignores the LED mounting board.

2. You can solder your LEDs onto the LED mounting board, then drill
holes in the panel to let the LEDs poke through. This is similar to
what we are doing with the new MiniWave CV-PROM daughterboard.

3. You can solder your LEDs onto the LED mounting board, then cut out
a rectangle in the panel and install a display bezel.

#3 is what I'll be doing. I'm planning to glue a piece of black felt
onto the LED mounting board and use water clear LEDs mounted on top
of the felt. When not lit, they look like little diamonds in a
display case. When lit, they throw lots of light forward so I don't
need as much current as I would with diffuse LEDs. The felt also
absorbs any light that gets reflected back into the module.

The display bezel is Digikey #PRD360B-ND. The clear lens is Digikey
#PRD360C-ND. Here's a link to the manufacturers drawing:

I'll be posting better pictures once I get the final boards built. In
the meantime, here are some pictures of the prototype (300K pictures):

Ignore the LEDs, pots, and switches sticking out of the motherboard;
these will all be mounted on either the panel or LED board. Don't let
the 6 pin power connector scare you, you can also use the regular 4
pin power connector.
