Help with stripboard layout...
Well, it turned out i'm an idiot. After building a complete new 808 BD pcb from scratch that DID work i found that... I connected the output wire to the wrong pin of my output socket.so now i have 2...

I've just looked at Fonik's Baby 10. He is feeding his clock through a CGS Gate to Trigger converter then into his decade counter. He seems to be taking the gate output and sending that through the...

then surely the NAND input would be left floating? And there you have the whole problem in a nutshell. DUR.Yes, on a step where the gate switch is open, I'm guessing that the diodes on the other...

can someone tell me if the VCA is usefull to switch control voltages?Cause I am searching for a simple VCA design that could switch LFOs but also some audio oscillators for sick frequency...

Now the circuit is doing what it should. Nice!With both trimmer set to their max, the outgoing voltage is 1.198v with an incoming of 1.0v.I tested also with 91k resistor instead of the 100k and got...

I would check the oscillators for their calibration.Do 1V steps on the non-Buchla oscillators actually get you good solid octave steps?Do 1.2V steps on the Buchla oscillators actually get you good...

I´m agree. a lot of mess for adapting to this one layer PCB. Best option using a separate PCB or a 2 layers PCB.

You understand things correctly.I'm assuming by "pulse outs" you mean the individual steps coming out of the 4017s, and if so then yes, that's what you would connect to the center of your on-off-on...

those CV outputs could be affected by load though. I'd follow them with an op amp buffer. You could use a 100k pot voltage divider in place of the two resistors if you wanted to be able to vary the...

Hi guys.I did the waveshapres from Berfotron, they didn't work first so I asked Berfotron why? He said they to be able to get the desired wave the vco must put out 10Vpp.On page 8 in the big thread of...
