awesome! i have the DVD as well, I take it this is the same video, or should I DL this too?

there's a red line after the caps which indicates you need to install a jumper. you can just use a clipped component lead or a piece of wire.

the pt2399 used in Ray's delay circuit is inherently noisy. I recently built his VC delay module and it exhibits the same digital noise. Not much you can do about it, but maybe try different values of ...

good call, was trying to open in firefux (sic) browser. works with VLC.
Nice project as always PHOBoS!

Alright folks! I've gotten all the bugs worked out and have a fully oscillating Mankato!
As I proposed in my initial post, the solution was to decrease the feedback resistor. It's 18k stock on the sc ...

demo video isn't working for me. says the file is corrupt Sad

the analog and digital grounds likely connect at some point. The key is to keep them separate until they reach the power supply to avoid as much noise off the analog side as possible. You shouldn't ne ...

i've double check all wiring and pot values. Did you use an SSM2164 or a Cool Audio V2164? What type of caps did you use?

hey all,
i'm having an issue with getting my Mankato filter to self-oscillate properly.
With the res pot and trim cranked, I can get a high frequency Sine wave out, but when I reduce frequency below ...

I'm having a hard time finding demo clips of the 4046. Fonik has one or two and that's about it. What existing vco would it be comparable to?

ive built 3 X-4046 VCOs and they're fantastic. Fonik of ...

love it Top Top! keep us updated on your shenanigans!

looks great! thanks again for sharing

any info available for the sync process? i'm not sure i see it implemented in the schematic.

the forum wasn't getting any new posts and i don't think he could really afford the server costs.

Its gone for good Sad

I think he left it up for a bit so everyone could grab what they wanted. Was there anything in particular you need?

oops looks like i forgot to include a pad for that.
you can add a pad or solder to the junction of D2 and R12.

also, you can get polystyrene caps in the US from Mouser.

Lovely build as always E. Peasant!

you can use NP0 or C0G rated ceramic capacitors in their place.

looks awesome, thanks for sharing!
looking forward to building one!

couldn't you resquare the waveforms to 50/50 pw with 2 - 40106 schmitt trigger gates?

ive built 3 on +-12v and no parts substitutions

Any schematics or build experiences out there?

Thoughts?

ive done this on quite a few modules and i've had good success with clear enamel spray paint.

It's a delay circuit
