JLCPCB Prototype for $2(Any Color): https://jlcpcb.com
Analog filter board with lots of intrigue. Is this connector really 3.96mm, or is it 5/32nds of an inch? Can the filter layout accommodate a totally different circuit using the same component footprints? What's this new 8-way ribbon cable for? How do you stop a sample and hold circuit from leaking? Answers within 🙂

    This has got to be the longest running project build.

    That Vocoder looks sooo cool with all the boards attached. It should be mounted in a transparent case.

    "they don't care very much" — well neither do you buying offbrand kit. Just sayin'

    What happened to the TL081? Your board does not match power supply to chip as it would be pin 7 for vcc etc

    We used to know the 5/32" connector as 0.156" pitch (it's actually 0.15625" but I don't think a quarter of a thou bothered anyone then). Frequently found on equipment designed in the usa.

    Have you tried making your own PCBs yet?

    Julian i am making this, something for you? create your OWN grit from solar with Battery Back-up and return solar energy to the grit, but you can a lot without the grit with this.

    Why not drill holes on the edges of the bar graph boards and put some threaded rods in there with nuts then you can adjust the depth easier(maybe even glue a nut to the faceboard then you have to bother with sliding bits) and also the side try using like a double side u channel for sliding
