Nice work w00t
Barcode
I was able to test the driver tonight and it works just as expected. The vibrato adds just an awesome effect to this VCO.

I think I'm at the point where I can say the VCO Core and Driver PCB's are in correct working order. I hope everyone has fun building their's.

I plan to add more demos once I finish building the last 2 VCO's. This is such a fantastic VCO!

Here are the most recent BoM's. All of the components are the same just a couple designators are different.

June 19: I made a change to the driver BoM. The Octave trimmers post were missing. There was also an extra 100n 2.5mm cap listed.

July 5: Updated the BoM's to show the correct pot types.

Glad you enjoyed mate!



Was checking the BOM, noticed you left the 10K as the pot for the coarse frequency. I used a 100K pot and thought the result was very good, 10K would be for a 10 turn pot.

I haven't tested with a normal 10K pot, but if you used one and it works as expected then it's ok! thumbs up


EDIT:

Can't wait to see your demos with the complete set! applause

As far as I can tell the 10k pot works completely fine. It can go from the LFO range to nearly inaudible highs.

I'm hoping to get the last 2 built up and have everything wired by the weekend.
Barcode
I had an extra set of PCB's and they are now "Gone".
Phetus
Gone?
Randy
I was wondering that too. Where's he gone?

Check that post now. lol
Randy
Ahhh. Now it all makes sense.

After looking at the driver PCB the tune pot might be backwards.... I plan on trying it tonight and I will report back.... Sorry.
Barcode
I confirmed that the Tune pot on the driver reacts backwards... Turning CW the pitch goes down and CCW the pitch goes up. I'm in the process of adjusting the gerber files to apply the fix. Literally it is just swapping to pads.

If you already ordered your PCB's it's a simple fix. Just 2 trace cuts and 2 oops wires. I'll post a picture of the modification I did on mine a little later. Sorry guys...

Here is the fix for the tuning pot. This only applies to the original version of the driver PCB. If you are using the gerbers below the fix was already added.

Here are the most recent gerber files.

No big deal. As long as it's documented, little adjustments like this shouldn't impact even a ham-fisted solderer like me.

Stuff like that happens. Easy fix is an easy fix.

I have ordered the PCBs for the EU-zone today.
The order is based on the latest Gerbers.
If you want to know if you are on the order and the amount please check page 29 where you find an updated list.
I will calculate the exact price and send everyone on the list a PM.

My sentiments exactly!

I finished building up my 2nd and 3rd cores this weekend and they turned out great.

I was also able to get them calibrated. I was able to get they to track over 5 octaves with barely any turned of the trimmers. Now I just need to finished wiring everything up and I will post some demos.
