As you know, I like overkill for the sake of overkill. But sadly, in this case, the thickness is almost entirely from the insulation. The pre-soldered wires with JST connectors were advertised as 22 gauge, but there's no way that's true. The actual conductor is pretty small, I'd say it's...

I had some requests for the Gerber files. So attached here is: Schematic Drilling template / potentiometer offsets (not the same as PedalPCB!) Annotated BOM Gerber files I submitted to JLCPCB Grim reaper enclosure art (with bass and treble labels fixed) Note: all files are either PDF or...

Yes, it's extra optimization where none is needed. But I like to say: anything worth building is worth overbuilding.

Here's my build of the Aion Procyon, based on the BJFe Honey Bee. Kevin has a great writeup on the Honey Bee circuit, based on his extensive research and tracing this circuit. The short version is, there are several variants of the circuit, loosely based on which brand was selling it (BJFe...

Finally joining the party! Full Build Report Here. Great circuit!

Here's my take on @Chuck D. Bones's Hybrid Fuzz Driver Deluxe. A long time ago, I built the Skreddy "Holy Trinity" using PedalPCB's Aldrin Fuzz PCB: The Lunar Module (Aldrin Fuzz stock), Hybrid Fuzz Driver, and Screwdriver. I've done a lot of builds using this core topology. One of my...

I use 2n7000 for this application because it's current-production, cheap, available from many sources, and is still readily available in a TO-92 through-hole package (2n7000), as well as a SOT-23 SMD package (2n7002). In my experience, it tends to be cheaper than BS170, though I would expect...

The build and pics are so clean they look like renders!

Referencing the first two schematics shown in post #1: the first is the original Diamond Peak, and the second is Chuck's first-pass modified version. Specifically, I'm curious about what I think is the bias network for Q1 (R3, R6, R7; and C2 in Chuck's version). My naive take is that Skreddy's...

I see what you're saying. I suspect that happened as a result of the bending. But either way, even if they are bad solder joints, those are the bass and treble controls, I don't see how bad solder joints on them would cause a short (I would expect no signal or unresponsive tone controls)...

What about them looks sus? @z2amiller - "actual fuzz pedal", that's hilarious! All those little bits are fibers from the cloth or Kimwipes I used to clean the flux residue off the back. I wouldn't expect them to be conductive. Though now I suppose I should add a compressed air cleaning step...

That's definitely plausible! Sorry, I originally posted from work. Original post has been updated with schematic and pics.

I had an interesting experience this weekend. I went to add my CDB-mod Animals Diamond Peak to my board, and when I plugged in the power adapter, a digital pedal on my board (Boss GT-1000CORE) rebooted. I thought that was weird, and then I went on to notice that the Diamond Peak wouldn't turn...

I didn't vote, because I like 'em both. Slight preference for Slurpee... But I can only print black waterslide decals, and I expect those would show better on the lighter Lilac. So call it a draw for me. Although it's not too different from you standard Tango Green (which is one of my...

Gutshot please :)

So I continued to research on this topic of ideal bias resistors for this electronic switching scheme, and I actually landed on 100k as pretty-good-for-the-generic-case value. Details in this post, but the gist is: Noise: 1M bias resistor has about 18uV or -95dBV of noise (not hifi, but...

I haven't studied ceramic cap datasheets exhaustively, but from what I've gathered, it's generally pretty rare for the manufacturer to actually publish the voltage de-rating specs. That's definitely an option, but not one I really considered for my SMD designs. The main reason is cost: I'm...

Ahh, so good ol' fc = 1/(2piRC). So really anything with a cutoff frequency below 20 Hz ought to be good, right? I'm actually using 1uF coupling caps when I do this with through-hole components, because 1uF film is readily available (and not terribly expensive). But I use 4.7uF in the SMD...

Does that imply something around 100k for 1uF caps? How did you derive these resistor values? Also: what is the effect of making the resistor values too high (as I have previously done)? I've been using the bypass with the "wrong" 1M resistors for quite a while now, and I don't perceive any...

For capacitors, you can go up in voltage rating. The 25v on the PPCB silkscreen can be interpreted as the minimum value. The only issues with going higher are cost and physical size. 1.5x to 2x is a common rule of thumb safety margin for capacitor voltage ratings. You can often get away with...
