Muff's Modules & More

for the unipolar switch, you could use a pot w/ a push-pull switch... i do this alot to sneak in an optional feature... kind of adds a "secret" element that i like

even without the switch i'd use linear pots just in case you want to use it for cv

i guess im used to trying to make my modules as universal and dense as possible

thats the sacrifice I dont want to make. the answer is to make more modules. one for CV and one for audio.

fair enough - i suppose if space is of no concern build 1 of everything smile

attenuators

$59 no fill
$79 white infill

maybe $40 in parts to build it

EDIT: updated the design. this looks way better and its cheaper.

MOTM format attenuators

So I've finally decided on a feature set and design for a Dual J3RK 258 in Euro... just want to make sure my bleeding eyes are not missing anything. Dead Banana

The PCBs are about 26hp wide, so this is 28. The large knobs are Davies 1913BW, 1 1/8" diameter and available at Mouser. I'm using 1900s for the rest. (Same height - nice match.) I'm implementing the saw/square waveform switch and adding an LED. I've brought out all 4 waveform taps to the front panel, hopefully I can fit all 4 buffers and an LED driver in the muck(s). If not, I'll have to make a daughterboard... 'SCV' stands for Shape CV, i.e. waveshape CV.

Holes - 6mm for jacks, 7mm for pots, 3mm for LEDs and 6.35mm for the two switches.

Thanks, wigglers!

Looks great Negativspace. I have always like your designs.

If it were me id put your bottom row of knobs above the fm row since you have jacks below them. Im not saying that because im the kind of guy who likes all jacks at the bottom and knobs at the top but more so you dont have jacks obstructing controls.

That's the waveshape control, sin->sqr/saw.

If it is usable for you fair enough - i think it makes sense to have scv pot closer to inputs and fine tune near coarse.

I'm taking this thread to be more a place to look for panel mistakes rather than to critique panel layout/design . . . though I do agree w/Luka hihi

I don't see any obvious flaws or omissions on this one.

pretty sweet to see matching layouts. how much did they cost each?

I agree with emdot, but I think it's practically impossible to avoid a little layout critiquing - and that's fine. No sense fighting it.

I also agree with Luka - the control arrangement is a little 'off' as I mentioned earlier because I wanted to stick to the established pattern. I'd like the fine tune up near the coarse knob too, and the shape controls could go nicely in the bottom row with the SCV... but there's no room to label the fine tune control that way. Its position makes it intuitive to grab it as the waveshape control, so I can't rely on proximity to label it for me. seriously, i just don't get it

Trust me, I tried every iteration...
