Is there a simple way to measure how many milliamps a module draws? I've got a suboscillator, a psycho lfo, a synthacon filter and others on the way, and don't want to overload my power supply. Thanks.

A diode based modulator is a good place to start for making Dalek voices, as that is what they used originally. (I have no idea what they use now.) Have a look at the CGS58 Utility LFO. The core of that would be capable of generating the triangle wave, though might need tweaking

hi there are plenty of ring modulator schematics on the web. i suspect you would have to try a couple to find the one that suits your purposes best. most are fairly simple to put together. possiby one with the mc1496, or Ken's passive ring mod would be good places to start. you w

The wires all look like they should acordingto the diagram. There's only three modules on that supply, so it must be in my soldering. The part I can't figure out is that all the outputs work like they should, no interaction of the speed knobs or the waveforms. I will go over it t

So I finally got my Digital Noise module wired up (after like a year). I have 2 cd4006 chips, one from RCA and one from NTE. I put in the RCA chip first, it creates oscillation instead of noise. So I swapped it out for the NTE and it worked great... for 2 minutes. Then it got rea

I have just completed a sub-oscillator/harmonic sequencer kit from Elby. All inputs, outputs and pots function and/or alter the sound. However, I think the 4017 may be kaput, as nothing comes through when point B is connected to C (A works fine), and /2, /3, /5 or COM are connect

Would there be any problem with replacing the pots in a CGS DC Mixer with on/off switches? So instead of being able to adjust each input's amount, you would just turn it Off or On. That would work wouldn't it? Andrew (newb)

Hi, Ken's CGS14 is a common low-cost power supply and will happily run the modules listed. If you want to go for a slightly larger unit that will support an extensive number of additional modules and uses a higher quality circuit then you should look at my PSU-2 ( http://www.elby
