Bring out yer Diptrace

[finebyfine]

I certainly don't have any insider information but the various forum postings i researched on it had many people agreeing that the extra diodes affect the tone with the Texture turned up.

As far as discrete transistors vs. Darlingtons, it seems many people reported less extreme gating in the stock circuit with discrete pairs instead. I'm gonna throw trim pots on all the collector connections that connect directly to VA just to have that flexibility.

Has anyone ever told you that you're a bad influence lmao and this doesn't even show the two on the first darlington pair

I just tied together the collectors of Q3a/b

lol @Big Monk that's what I ended up doing too, seeing 6 trim pots on a board felt a hair excessive

Wait until you see my relay matrix order switch circuit.

Mostly I just want to control how excessive the gating it. With that many collector connections straight to the source voltage, I found in my botched Scrambler nightmare that having control over the collector voltages could help dial things in.

Further to hand-soldering...

I did that a couple years ago while building a boost for a friend.
Kept my eyes on the prize and reached over with peripheral vision and grabbed the soldering iron like the purple-shirted lady...

Unlike her, however, I didn't manage to get the iron over to what I was working on.


SHO did hurt.


Lurking mode re-engaged, back to your regular-scheduled Diptrace-trip flip fantasia — Biddy bibby bop...

Pleasant surprise on my porch today

 

[Robert]

Yeah, that would be great! Thanks!

Mine was designed for using the PCB pin version of the rotary but I've just made an alternate that should fit the solder lugs... Or, you could probably clip the eyelets off each pin.

I have one of the switches on the way to verify.

I missed the post where you previously mentioned this board, but just wanna say that looks fantastic! Never heard of that circuit before, but your praise makes me think I better breadboard it up!

yeah, clipping the eyelets seems like it would work fine— the ‘legs’ of the eyelets are pretty long, so even after clipping they’d be plenty long enough to get thru a board.

Yep, I think so. Tayda only has the 1P12T with solder lugs. Mouser as the version with PCB pins but the shaft is a lot longer.

I was thinking of revising my ancient variable high pass filter/one band parametric EQ board that I've used in several amp and preamp builds. And what do you know, I had already mostly done that last year and promptly forgot all about it. The old one was all through-hole and measured about 4.5 by 2.5 inches. This one is 2.5" x 1.6" and offers many more opamp options since SOIC-8 opamps are pretty much the thing these days. One notable feature is that it doesn't need to use any dual log or antilog pots, unlike the vast majority of HPFs and PEQs.



And then I'm wrapping up a DC-DC converter daughter board so I can use the new board in pedal builds without needing a non standard power supply. 9V in, +/- 15V out at >60mA:

Breadboarding it is apparently easier lmao, I can’t figure out why the board isn’t working

 

[Robert]

Just to follow up, yep, that works just fine. I'm still going to modify the footprint so they'll fit without having to clip anything.

Oooooooh! sp12t and cmos chips together makes me think… something fun is coming without a doubt, and I think I might have an idea as to what it is

I have a good friend that bugs me consistently to build things for him, and one he's asked about for a year or so has been a tube-driven FV-1 platform. So I buckled and threw it together. The weird looking pads down near the bottom are for "solder blob" jumpers, I wanted to try those out. If you connect the bottom left one it operates in true bypass, if you leave that open and jumper the other two it operates in buffered bypass so you can get tails out of delay repeats. Theoretically, anyway.

Some recent layouts schmidt trigger fuzz from an 80s magazine, jen hf ring mod, and clean octave blend







ooh and these showed up from oshpark, which are just little vactrol to dip-4 boards to theoretically make socketing easier. unfortunately I have not found an easy way to solder header pins onto the outer pads

 

[vigilante398]

I'm doing an onboard bass preamp which means I'm dealing with batteries, and I've always hated the "the battery is fine until it starts sounding bad" perspective so I designed a battery status indicator that will mount in the bass.

 

[Feral Feline]

I don't see a micro tube (6111 for example) in that diagram, or is that diagram JUST for the battery status ...?
