ah crap!   stupid google photos.  I hope it's working now.  I'm signed out of google and can see them.

I made some PCBs for the ROG Thunderbird, being legit and following Brian Tremblay's licensing agreement (think i might sell a few).  I tried to follow good layout technique, but to be honest, all i know is to try to keep the power separate from the signal, then after a while of routing, that is out the door (I think i ran the Vcc right under one of the voltage diodes). 

First build sounded amazing, but had a high pitch noise, and the white noise was too much.  Tried shielding and that did not work, finally figured out I have bad batch of LT1054's (ebay) (5 KHz switching freq) and once i found a good charge pump, it was much more quiet.    I'm going to avoid charge pumps for a while, struggling with bad ones in a few other builds (although TC1044SPCA's at mouser are like $1 right now).

Anyway, this thing sounds awesome, and super loud.   Octagon enclosure, water slide decal, graphic I got from a "one sixth warrior" forum, a guy in korea made a 1/6 scale jimmy page with this suit and I found his suit graphic.  I wish i could still find the photos of it, it was insane, little Jimmy with little LP and pedal.  I'm trying to pay him as well if I sell them, but he's not responding.

Build Reports / Dig Doug
July 29, 2017, 08:52:00 PM
Here is my completed dig dug 2, made for a friend who came across Brian's demo and really wanted one.  Searched for famous Doug's for a graphic, came up with Doug Henning.

After drilling, had no room vertically, the board is jammed up against the stompswitch, which is jammed up against the octagon.  Had some trouble with the step switch, think i got some drill shavings in it, it would only work on odd numbers, even would go full 8 steps.  Think i have it clean now.

Put the rez and filter pots on the bottom.  The trem side seems lower gain, i may add a resistor in line with the trim to bump it up a bit.

Love this thing, very fun.

Awesome, glad it worked for you!

**Edited**

So referencing the zero point micro II (2014) schematic you could remove the mix pot and just have that line go straight into C14.

Remove R4 which mixes the dry with wet on the output buffer.

Run a coupling cap (1u?) from pin 1 of IC1 to lug 1 of a B50K pot, this will be the blend Pot.  Lug 3 of this pot will get the signal after C4 (out).  Then the wiper of this pot, lug 2, is your new out.

I probably have this drawn out at home, but i think this would do it.

Beautiful!   I'm getting started looking into jfet overdrives/distortion, never built any, not looking forward to learning about jfet measurements.

Build Reports / Feral Errol Fuzzes
July 07, 2017, 05:07:48 AM
A couple of fuzzes I made for a friend with his dog (Chinese Crested, Errol) as the graphic.  First is a 3 knob tonebender, which included a makeshift dying battery knob (not yet added) using a current limiter, LM334Z. Trying to experiment with the EM Distortion Box spectra knob (Charles R. Fischer).  Didn't really work on this, or I did it wrong. Stripboard and tried to pot mount it, so all bunched up at the top of the big octagon.   Clear waterslide decal trying black ink background, never really works right trying to make the printer do full black.  And my fingerprints are preserved i think.

Next is a fuzz dogg PCB, univox superfuzz.  So awesome.  Did the germanium, silicon and no clipping option.   Tone switch scoops the mids.  Love this thing, and you can see I learned how to do graphics a little better (not my photo, stole it from one of his gifted friends).  Sorry no guts of this one

Trying to start posting more stuff I've finished, failed at lots of experiments, but its all fun.

haha, glad it's working.  do you get it working without tweaking the trimmer between up and down envelope?

I'm dealing with this as well, and previous posts suggest it could be the use of non-VTL5C3 vactrols.  I have the macrons in and it works in the reverse envelope mode, but in normal mode the voltage is not getting there to effect the filter.  I'm going to switch them out and will let you know if it fixes it.

Open Discussion / RIP Ray Wilson
July 24, 2016, 05:34:57 AM
Looks like Ray Wilson has died.  Sorry to be the guy to post it, just saw the news and didn't see it here, i know there are many synth enthusiasts here.

I recently started into the synth stuff, so have spent a lot of time on his site reading his awesome write-ups of how each module/project works.  Made the subcommander, and emailed him a few times and got responses within the hour, hand drawn redlines on the schematic for mods.  Such an inspiration.
