What a world - VTL5C3 is the guy that made me think of trying a SVVCF based on the 2040 gain cell JH had worked out and René Schmitz later modified. Negativspace has really tweaked it into a demon here, particularly in the refinement of the front end and control circuitry, and very particularly i...

This is it. Triangle, sawtooth and PWM suboctave. Add two transistors and another op amp and you can add a sine output as well. Note the power supply connections on the CMOS parts. The inverters are CD40106 Schmitt trigger inverters. There's enough CMOS left over to go down another octave off of the...

Dammit, you spend hours and hours trying to design something as obtuse and un-buildable as possible, and NV comes along and undoes all of that effort in one fell swoop. And, in Euro-format no less.

Seriously, this is cool beyond words for me. Awesome work, NV!!

Huzzah, William! That's great work, and an inspired product.

I have a question - what would be the highest theoretical clock frequency your IC designs could produce?

It's fine with me. Go for it, if you'd like. It's not a terribly complicated thing, it's highly repetitive. I would recommend breadboarding it first - it's very easy to have the noise floor rise up once you've chained about 26 or so stages. You might also want to consider driving each /2 with its ow...

Well, it's nice to see interest in the MultiPhase. Right now, doing a PCB here would be a duplication of effort.

If you want to build a 16 stage with these, you'll probably want to dedicate a mirror transistor per stage and just tie each LED's anode to its own individual voltage. I used dual VTL5C3/2s; using singles will give you twice as many LEDs and you'd run out of voltage (assuming all of the Vactrols are...

Yeah, well you get a lot of credit on that walking stick; it was a solid build, it looks great, and it feels 1.2 zillion times better than a bare softpot, that's for sure.

Scot's a great guy; I think he's living my dream life and doesn't even know it :D.

Hey Chromium,

Scot Solida used a walking stick for his Appendage - it worked superbly. I got a chance to play with it quite a bit (he lives about a half hour from my house). Those are some nice ribbons!

Another cool thing about an analog logic module (max/min or peak/trough) is that it really is just a couple of ideal diode circuits, so it can easily rectify signals if one input is a fixed voltage (often 0V) signal while the other signal is the one you plan to rectify. When things are patched with ...

Actually, it doesn't require a 394. One can use any set of matched NPN transistors or matched NPN package in place of the 394.

I imagine people clapped for it because (as yet) it is impossible to send a load of hipsters thirty years back in time to mass-bag on the wrong playing of an instrument that was (and likely still is) largely unheard of to the vast majority of the Tonight Show audience.
