Pirx- thanks. The graphics are printed onto a white decal film with a photocopier. The sheet is soaked in water until it starts to come away from its paper backing and then slid onto the aluminum panel. Then it's baked in the oven to harden. Then the panel is trimmed to size and drilled. I get the d...

Not completely on topic, but I built a stand alone Neural Ag a while ago. Here are a few pics that I took while I was building it. If anyone wants to see better photos of the finished version let me know and I'll take them when I get home tonight. The case was from a laser Q-switch driver circa 1981...

Led sliders for ADSR

I have two ADSR style envelope generators that I built 5 years ago that I was thinking of repaneling with sliders instead of knobs. I have the ADSR knobs arranged two over two and in practice it’s a bit cumbersome to set them up. I thought a row a sliders where you could "draw" the envelope s...

Thanks.
I checked the sine at the drain of the j201. The signal is tiny and, alas, also affected by the waveshaper control. Pugix has a sine out on his. Maybe I'll drop him a line.

I brought out the sinewave to a panel jack (tapped from top of saw/sq4 and boosted), but its shape is affected by the waveshape control. Is this avoidable?

Another thing you could try is to make a planar cathode and orient it in parallel with your panel anode. This way, the current will be forced to flow in short straight lines from one to the other, and the etching will be more even (and possibly much faster). That's what I do. My cathode is a brass ...

I spelled it wrong. its actually 'rabbet'. Its a type of wood joint. It has more surface area for glue, so its stronger than just butting the wood together. Its the "L" shaped joint in the corners of the sketch.

East coast: subtractive synthesis. heavily filter orientated. Often leans towards the typical instrument patch VCO->VCF->VCA with ADSR type envelopes. Keyboards and sequencers are common. West coast: common techniques are non-linear waveshaping, dynamic depth FM, & control of spacial dynamics. Typic...

Thanks everyone.

The pushbuttons are from Mouser: 10PA005 for the red ones. They also come in black and white.
If you use them in the prog/ seq be aware they interfere somewhat with one of the buss wires that run thru all the boards. Some teflon tubing will keep it from shorting.
