Any DIY pedal builders on TB? Strut your stuff!

I've got a couple of little transformers *(salvaged) that look identical to those in Ficelles table-top comp, but mine are unmarked so I've no idea if they're even meant for audio.

Mine are also unmarked... 3 pins one side and 2 the other suggests balanced to unbalanced, not sure how you'd check though?
 
This week's entertainment - isolation transformers for my desktop Thumb compressor build's XLR i/o... and if one Thumb task wasn't enough my PedalPCB version has arrived which will make my third build of the circuit. You can probably guess I like this compressor :)

I've got the PedalPCB Engineers Thumb but haven't assembled it yet, it's probably still a ways down the pipeline. I'm looking forward to your opinions on it since you've built a few different versions.

This week’s project. Etching box now . More to come later.

Works great, and you can also export to DXF if you have access to a local CNC rig. But FPE do a stellar job in a very timely manner, love those guys.
They really do. If I REALLY like the pedal I might order a top plate with engraved/infilled text from them.

I may also see if I can have the DXF file printed to scale on a durable sticker material, like a bumper sticker.

I had a few minutes to play around with it, add some more potential switches and pots. I also flipped the CCA and spaced the pots closer, so I would use solder lug pots and wire to the board. I have some time to figure it out and play with options.

The blue outlines show the physical size of the components. Jacks are at the top corners, I'll probably only have room for 1 loop (would I really even need 2?)
 
I finished this one this morning. It's a PedalPCB Mercurial Boost. I've got to say that I have been able to pull tones out of my P bass that I've never heard before. I'd recommend checking this one out. It's based on the Catalinbread Varioboost if you want to learn more about it.

i built a varioboost a while ago by etching my own pcb and enclosure for it, and i agree, it's a great pedal:

I'm easily lured into having another gated and crushed fuzz. Low parts count and using common transistors & opamps makes them good for stripboard builds. I can get started right away so they often cut the line of DIY projects.
Raffel's bitcrusher is also release by FuzzDog as the Fuzzpup Crusher. Madbean has a past project called Horndog based on the same circuit.

@JoeDaddio that Mercury boost looks amazing!

Thanks for the above info, I might try and lay either the Fuzzdog or Madbean schemo for perf.

BTW, my Fireaxe arrived today :hyper:, but I have no plan of attack for it — not a graphic not even a name.
It came with the Flunkee I ordered, AND I found my freebie Flunkee along with some other MadBean PCBs fallen behind a bookcase (aircon went on the fritz, so was repairing that and had to shift some things around), so I guess that's one package that I didn't send to Canucka afterall... Means I could-of should've already built the Flunkee, now two what to do!?!

Actually, one Flunkee is reserved for a MFX, my Prison Rabbit build... one for stand alone — facing the same dilemma as the Fireaxe — no name, no graphic, no concept.

Such a tease...

Looks exciting and interesting. Ahh sweet mystery of life at last I've found you...
Waiting for Godot.



@AudioTaper, that new layout looks great! Really diggin' the inverted PCB.


@ficelles I'll try one of the little transformers out in a BazzFuss, that way I can't pooch too much if something goes horribly awry.

Waiting on an LTC1144 that should be here tomorrow, then I can finish. I could leave as is and run only at 9 volts but wheres the fun in that. Looks like Im going to have to build an 18 V charge pump. Vero or pcb , hmm decisions, decisions. Guess Ill see which takes up less space. Careful F Feline, you know what they say, curiosity killed the cat, lol. Honestly, its nothing spectacular but to me it sounds great. Cant wait to see if the increase in voltage is worth the price of the chip. Time will tell.
 
Here kitty kitty, lol. Finally done. Had issues with the LTC1144. Couldn’t get it to stop having a high pitch whistle so I decided to keep it 9v only. Got tired of messing with it and I’m not a very patient person. Thus the brushed look instead of polished. I buy blem boxes at a little lower price. They are meant more to paint. But again I don’t like waiting for paint to dry, lol.
