Any DIY pedal builders on TB? Strut your stuff!

Finished my PedalPCB Thumb compressor. Interesting to compare this with my other two versions of the Engineer's Thumb circuit as the PedalPCB BOM is a little different and they have reinterpreted the circuit a tad. It most definitely works, but doesn't easily trigger into more extreme compression like the FuzzDog and DeadEndFX versions to. So maybe that's just my build for whatever reason, but the result is a more subtle compressor that is very transparent. So that's my 125B pedalboard complete!

L-R ThumbSucker compressor, Sentient Machine modulated filter, Hydra delay, Haarp arpeggiator, 6-Band EQ, Ocelot octaver. Maybe I can squeeze one more on there?
Very nice looking board. There is a certain kind of satisfaction in knowing you built everything yourself. I applaud you.

You could definitely squeeze one more on there — if you built them all with top-jacks! :woot:

Great looking collection, and a great selection within the collection!

Very interesting your findings on the Engineer's thumb builds. I've got the JMK version and was going to leave it at that, but if I ever manage to catch up it'd be cool to do some comparisons as you have.

Speaking of comparisons — I've got the Aion HM2, definitely going to get the Dunwich one, too.
Thanks again Mr Dunwich!



This is where my head is at. I would love to build little drone synths. Still haven’t opened my kit...maybe next week...

Get on it! Do just the resistors, today! You can double-check your work on them tomorrow, and then tackle the next tallest component, a bit per day and work your way up to the big electrolytics ...


@G.Bisson Beware of false "Buffered" chips. I keep ordering from different places that each assure me they are selling me buffered 4049; All I can tell you is my collection of UNbuffered chips has grown exponentially and that I still have yet to find a source for the damned UNICORN-BUFFERed chips.

I like the 4049ube, but it's getting ridiculous — I've got a GREAT BIG list of UBE-builds if any of you are looking for ways to deplete your stockpile of 4049ube...

Please let me know if you're able to score any buffered versions. I've still gotta make that dual Great Destroyer — it uses both sides of the chip instead of just one. Waste not & what not.




@Fuzzonaut Have you checked out Music From Outer Space (MFOS)? There's the Noise Toaster PCB, and the MFOS Alien Screamer has a vero-layout kicking around the Net. It's NOT a Tube-Screamer. ;)

There's a couple of cool-but-Pricey projects from the guy that does the Tune-in-Tokyo (I'm going to get the PCB, but there's vero layout for TiT, too. Tune in Tokyo | Rare Waves
Grendel Drone Commander, but I think it was the Hydronium that caught my attention (after the TiTokyo) IIRC.


Check out 4MS Noise Swash, if you haven't already:
VERO Guitar FX Layouts: 4ms Standard Swash
Kits/PCB may still be available for the regular, but not the Deluxe.
Random Bassline Generator is another must-have for me. Seems always sold out, though.


Kastle has some bleep-bloop bitty projects I like.

A few noisemakers at Synthrotek that might be of interest.


This one is a must-get for me:
HARMONIC ENGINE - E&MM Harmony Generator clone PCB by Circuitbenders on Tindie


There's a really cool project that hopefully will let me play my bass/guitar through my Atari Punk Console project, it's an...

If you're interested, I've also got links to a project that sniffs out electromagnetic interference and converts it to an audio signal.

Then of course there's various light-to-sound and sound-to-light generators...

Yup, the "to-do" list is pretty long... I hope to some day have the skills built up and the time and money necessary to pursue some of these more esoteric endeavours.

Sorry, it only takes a little encouragement and the floodgates open...

Still haven't managed to get to my local shop. Ran out of 22k 1/8w and it's for another tight build so I don't want to use 1/4w or resort to resisters in series.

So that's given me time to rethink my DOD FX25 project (Madbean Flunkee)... I'm planning on adding a clean blend, and what I'd like to know is:

1) Does the 13700 invert phase?

2) On the clean blend, what LPF corner frequency would you shoot for ? 1600Hz, 800Hz?


I asked over at Madbean, but have only one response so far...
 
Doesn't that depend on how you use the op-amps? Each one has + and - pins...

Looking at the flunkee schematic I'd say maybe it does invert the way they've used the 13700, but I'm probably not the right person to answer :)

Right you are.
The FX25/Flunkee schematic shows all non-inverting op-amps, but I've read elsewhere on TB that the FX25 inverts. So I checked the data sheet and I'm not sure what's going on with the in/out buffers in the 13700 — verro over at Madbean said it's non-inverting and pointed out that buffers don't invert.

Well, I'll just build it w/o breadboarding, if it sucks I can snip out the few bits that make up the buffnblend.

It's already a tight squeeze, but if I'm able to include a clean blend on the Flunkee for 1590A, that'd be sweet. Not sure there's room for even one more R/C to get a LPF going, but ...

Suggestions for a corner freq on the clean blend?


BTW, I tagged you over at PPCB, somebody is looking for feedback on the Engineer's Thumb build there.
Thanks for your reply above.

Cheers,
FF

Oh my, thanks for all that info, @Feral Feline ... I'm going to stroll through all this with pleasure. I do know the MFOS stuff, I have had a Weird Sound Generator for ages now (built by DIRGE though), great box! Noise Swash seems to be right up my alley too .... and I remember having seen Moody stuff before ...
 
I have it booked marked for easy reference. Is the stand alone LPF available or will it be?

It's coming, I just have to decide on a default build spec and work up the BOM now:

Four days from ordering the boards to having a working test unit on the bench. I love it when OSHpark gives free service upgrades!
 
Just finished up my PedalPCB Mini Heterodyne Receiver. Now I get to figure out how to use the darn thing....

Not 100% set on these knobs, but it's what I have on hand. View attachment 4278821 View attachment 4278822 View attachment 4278823
Anyone else ever build one of these? It has an insane amount of output, and I'm wondering what the heck I'm going to use it (the effect itself) for. I hate to say it, but this might be one that sits and doesn't get used a lot.

On the other hand, I'm still really digging this Spirit Box Reverb.

I've built the big one ... and added 2 mods: one of them tames the madness a bit (add toggle switch). If you want to add that, let me know, although there is not much room left in there.

As for using it: Well, it's a PLL thing, ..... I had it on my board for a while, purely as a crazy noise maker ... but it ended up on a friends table top set up where it mangles a drone synth and also acts as a sound source by itself.

Cool, wheres that toggle go?

I have the full one built but not boxed up. I was planning on using it more with synths than bass. I imagine it'll be pretty fun with my Microbrute.

I watched a video on YouTube with one and thought 'that's cool'. I feel misled. It's cool in a way, it's just not what I was expecting.

I'd not heard of PLL's until I saw all of @ficelles builds not long ago and I did some research in to them then. If anyone can tell you their use here it's probably them. After looking in to the different versions I thought of it more as a weird kind of pet-project that would be more fun to build and play with than something that would actually be musically useful in a song or band setting.
 
well, not that fast ;), i just ordered the CTG and the HM-2 PCBs today.

Another TB'r is working to verify the CTG as we speak. I had launched that one discretely until its verified.
Assuming he and you are the first two to finish it, once its be built twice I will officially announce.

I have more stuff coming out.
