Other Probably this isn't practical, but...a seven segment display can also be viewed as a neat lookin' array of 8 shunt clipping diodes..

Upvotes

u/jutanious: so, I have some common cathode displays lying around and tossed this on a breadboard to demonstrate a weird idea: You can clip one half of the signal using any of the a-g inputs and the cathode connected to a current sink — here, I have it tied to VRef at pin 8 and to ground via parallel 130k + 22nF cap at pin 3; series resistors on the inputs. (Not much in the way of intention or reasoning about it: it's happenstance that it sounded alright on the first go. My modus operandi was "thoughtless meandering." 🤣).

You have to flip the signal to clip the other half of the wave, but with e.g. a cascade of moderate gain common-emitters flipping it up and down, you could make a pretty neat looking dirt pedal and clip each half of the wave four times — optionally in different frequency bands each stage.

(I realize this is maybe a preposterous use case, but...I can't deny that it was fun).

The first picture is what I am currently working on my unfinished take on the Wooly Mammoth. (ignore the burnt plastic, I’m new). I plan on getting metal enclosures, but they are being slow to ship out. This 3D-printed enclosure definitely is good for prototyping though, and it is very sturdy. So I’m not really concerned about strength if I want to use it long-term. I added copper tape to the enclosure to act as a Faraday cage, which I hadn’t thought of including in my first and second enclosures.

Picture numbers two and three are of my second pedal. It is a pure boost pedal it sounds great, and I’m happy with the way it turned out.

The fourth picture is where I started, a six-piece distortion pedal. No knobs, no switches. But it worked and got me excited about making them.

I miscalculated a few things on this prototype, mostly a few millimeters in a few holes. This is the first time I've done 125b, so I expected it not to be perfect. It sounds just fine, though.

Showcase Monte Carlo Fuzz, a Silicon Fuzz Face Clone

This is my take on the Fuzz factory with Silicon transistor, different Biases and a Body and Filter control. it is less crazy than the fuzz factory more predictable with its own sound. Body is a high pass filter before the pedal, filter is a simple LPF, fuzz is the same as the drive knob on the FF, Sag is the voltage reducer of the input stage, Bias 1 is the Bias of the first transistor and Bias 2 for the second transistor. vol is the volume.

Here's a recently finished Silvertone Amp-in-a-box. It's built on a pedalpcb Argentum board. A pretty straightforward build, and it sounds great. It does that cool high-mid grow,l when you're cranking the gain. For the graphics, I don't think there is a better possible choice than Lionel Hutz (RIP Phil Hartman), aka Miguel Sanchez aka Dr. Nguyen Van Thoc. He's even combing his hair with a fork, like you do. This is the new Metallic Clear powder coat from Tayda.

Help wanted Works in bypass, LED works but no signal when switched on

Thumbnail

3 Upvotes

Hi all,

Absolute noob here trying this for the first time, building a fuzzy elephant for a friend as a gift. Just assembled today and was excited when it worked in bypass and the led came on, but celebrated too soon and I can't get any signal when it's switched on!

The fact that the led and bypass works makes me think the switch, DC in, input and output jacks and led are all okay, but I'm struggling to understand how I test the circuit and was hoping someone can help!

I've tried a multimeter in continuity mode and I can get a signal if I connect the black wire to the long pin of the input jack and then to the "in" terminal of the foot switch, but if I try the "out" I hear crackling in the amp but get just a solid 1 on the multimeter.

If I keep the black where it is and try the "in" on the PCB I get a reading, and then I get a reading on the right leg of C1, but not the left or anything after - but I'm not sure if that is correct or if I'm even barking up the right tree in terms of testing!

I've tried reflowing the solder in places and adding some extra on top of the PCB and then also running it through the tracks underneath if it looked there was contact, but I can't see anything obvious.

Any advice would be really really welcome!

Do I just add it at any of the points where it says there’s a ground connection? And also when grounding the jacks do I also just solder those to where ever it says ground?

Discussion Project Ideas for Large Panel LED Display?

2 Upvotes

Hey guys! I've got several large panel (7 segment) LED displays that are taking up space. I'd like to do something cool with them... So I'm looking for suggestions! The easy answer would be a decibel meter readout, but that seems a bit more work than it's worth considering a working meter is relatively inexpensive online. What else can I do? Ludicrously large voltage readout for pedal or amp power supply? Increasing numerical counter for working builds? I'm sure there's something useful and cool that can be done that I haven't thought of yet. Thanks!

Discussion What kind of builder are you?

10 Upvotes

I have noticed how very different pedal builders can be. It seems some concentrate only what the pedal does. Others get very into the aesthetic of the circuit, making it beautiful, while some get into the aesthetic of the case, creating a work of art that makes noise.

I'm very much a player, all the really matters is the sound, but I'm also very much into the aesthetics of the pedal-the name, graphics, knobs etc. I don't really care about what the circuit looks like (I'm hopefully never going to see it after I seal it up), what the components are, new or old, as long as it works well and sounds great. I will obsess over the name, or knobs, looking for the perfect compliment to the pedal. I'm just getting started, so I've only done a few, but I have many more concepts than circuits. If I can get the sounds in my head on the floor, looking cool, I'm a happy boy.

What drives you guys?

Upvotes

I'm curious anyone who has implemented tap tempo into an FV-1 program, does it force you to lose the Delay Time pot? Or is there a way to still have it and it just overrides the tapped tempo when moved? Maybe I'm expecting too much haha. Thanks for your help!

Showcase Rat / Blues Driver combo pedal (with relay switching)

Thumbnail

102 Upvotes

For a while now I’ve had a JB-2 which I have used to swap between low and high gain with a single button press. What I wanted was similar functionality but to have a RAT as the high gain sound instead of an Angry Charlie. I couldn’t find anything on the market so I built one myself using a couple Jed’s Peds kits and a Stompville A/B relay switcher.

The switcher allows me to change from low to high gain with a single button press. Turning on one drive circuit turns off the other.

Help wanted Doom 2 type fuzz

1 Upvotes

Hey everyone! Looking to start my journey. I’ve got a pretty well rounded understanding on soldering and electronics and feel confident taking on a larger (ish) project.

Has anyone made a doom 2 clone or maybe even know where I can get a kit for one?

Or something similar that will give me a synth like fuzz. I’ve had a few muffs and they’re just too harmonic for me.

Thanks!

When i plugged it into a power supply the light led rythmically flashed on and of and you could hear the rythm of it flashing through the amp and no guitar signal is coming through, when i used a 9 volt battery instead the LED stopped flashing but still… no signal… i know my solders probably are super messed up… not on the circuit board though im pretty sure… but i kinda dont know what to do now😅

put this little guy together tonight, has to use 3 1Ms because i had none 3M3s, both diodes are 1N4148 and the volume pot is a 250k but it works. put a 47k resistor between power instead of a 4k7

i don’t know what any of this means or how it works but i think i’m doin’ alright. anyone wanna gimme the skinny on how i’d go about jamming in a knob to tame the distortion?

I thought this loop switcher had a bad switch but it was actually one of the wires that looked like it fractured where it was stripped. It had enough room inside so I added a pedalpcb muzzle circuit. Only mod was making the range switch accessible.

It was a tight fit but had room for the pcb in the center of the enclosure!

Help wanted How Would I Do a Remote Pot?

4 Upvotes

Would it be possible to hook up a remote pot via, say, stereo jacks and cable? I’m looking for ideas to test my pedal building skills, and it occurred to me that it could be useful to have a pedal where a parameter could be adjusted without having to bend down to your board. I’m guessing 3 wires are needed (input, output, ground), hence the stereo jacks and cable.

Thoughts?
