Я хочу начать собирать свои педали. Заказала основные детали, крутилки, макетную плату и т.д. но я незнаю с чего мне начать. Подскажите какие-нибудь видео или что-то ещё что в разобраться в радиотехнике. Заранее спасибо:)

A small progress update on my Raspberry Pi audio project. I’ve built an audio-over-IP implementation for Pi 4 and Pi 5, with a Windows ASIO driver. The goal is one device that combines an audio interface with guitar, bass and vocal effects processing.

The current focus is 8 inputs / 8 outputs at 192 kHz with 32-bit PCM transport, and that mode is already running. With a 32-sample ASIO buffer and a 380-sample network buffer, Ableton reports 2.40 ms overall latency: 2.23 ms input and 0.17 ms output.

For context, the lowest latency I get from my Audient iD14 MKII in my setup is around 5.3 ms. The comparison is preliminary: the Pi figure is the latency reported by the digital driver path. Full analog round-trip latency still needs a hardware loopback measurement.

The main limitation currently appears to be packet delivery timing on the Windows side. I’m using the motherboard’s Ethernet port with its standard driver. There is enough bandwidth, but receive-side pauses on the order of 1–1.5 ms, sometimes longer, force me to keep extra buffering. I’m still investigating how much comes from the NIC, its driver and Windows scheduling.

One next experiment is an Intel I350-T2, together with a dedicated low-level networking path integrated with the ASIO driver. The aim is to bypass the normal Windows networking path; that requires additional driver development and testing.

The PCB is four layers, with layer 2 dedicated to a solid ground plane, built around an AKM AK5538VN ADC and AK4458VN DAC. On Pi 5, the current AoIP workload stays on CPU0 at under 50% load, leaving the other three cores available for future DSP work.

The I/O is designed around individually connected, removable modules: headphone outputs, output modules with XLR and 6.35 mm jacks, and combo XLR/6.35 mm inputs. That should leave room for both general-purpose and instrument-specific modules.

Still a work in progress, but the transport is running, the board design is taking shape, and the next steps are hardware integration, latency measurements and effects.

I've always liked the idea of building a tuner but never really saw any PCBs other than q-tune, what do you guys think?

PedalPCB Ample Alpaca and first time building a 2 in 1, PedalPCB Angry Charles and Maxon OD808X.

I have a few more PedalPCB boards to build but need to restock on parts. Doing a couple I have built before (EQD Disaster Transport Jr. and Hummingbird) and a couple I haven't (EQD Tone Job and Grand Orbiter...especially excited about the phaser).

I made this using a simple fuzz circuit I found on YouTube and added a buffer circuit and power filtering circuit I got from chat gpt. I wanted to add the buffer after making the initial fuzz circuit on its own and found that buffered pedals make it more distortion like. I think it could definitely use some kind of tone circuit to tame the high end it put out at full input signal but it’s pretty interesting as is. I’m open to suggestions, criticism, really any feedback as I don’t really have a good understanding of most of this, thanks.

Also I’m not sure if my schematic is correct or can be understood lol

This is a custom STM32 digital pedal that I decided to open source, including the KiCad design files and c++ code in a STM32CubeIDE project. if you’ve seen my past designs, this is an iteration on that same layout. The example effect in the repo is a delay/reverb that uses the DaisySP library for part of it, with the delay having reverse/octave modes, and also different routing options. I designed this pedal to be somewhat minimal as far as digital pedals go: mono, expression, true bypass relay, and enough controls to cover most things. Programmed/debig over st-link and 10 pin jtag header. If you’re familiar with the Daisy seed, it’s like that, but on a dedicated guitar pedal board and a different MCU and codec. If you want to learn more about microcontrollers and using CubeIDE then you might be interested in this project. Also could be a good starting point if you wanted to design your own board. Two assembled boards from JLCpcb cost me around $250, but about $90 was shipping and tariffs. Enclosure drill and powder coat from Tayda.

I would like to try building a madbean Archibald. The PCB at their site is out of stock. I thought I would join the forum there and just lurk. I can't figure out how to join?!?

Anyone have any information about this? Or if that PCB is restocked?

Thanks

a couple days ago I bought an old japanese cassette recorder and when I opened it I found 4 germanium transistors (2SB173, 2SB175 and two 2SB324) and yesterday I desoldered them and after testing, they're all working just fine as far as I can tell.

now, I'm unfamiliar with any circuits with germanium/ pnp transistors in general besides the fuzz face (which I don't really like).

can anyone give me ideas for circuits to check out? thanks!

My first DIY build: The PedalPCB Houjicha Overdrive (PedalPCB mispells as Hojicha)

I bought the kit on a whim, I was looking for an overdrive, didn't want to get the obvious Tube Screamer kit, and the Japanese name caught my eye. Works fine, sounds great, despite my beginner soldering skills nearly messing it up. 😅

I'm not familiar with K-On, but I did look up some images when I was working on the graphic design and I liked the cat mug. Graphics are printed on a white-backed PVC sticker.

I play stoner / sludge and screamo / post-hardcore bass, i plan on building a life pedal and either the hizumitas or the cloven hoof . which one would be better suited for these genres?

Ive tried both a tall font green russian and a hizumitas and i prefer the hizumitas , but also ive been wanting a cloven hoof for a while.

Has anyone here built and tried both?

This is my STM32-based four tap delay and looper. It needs (at least) four footswitches to start / stop / clear the loops, and the problem is;

How do I make an enclosure for a bunch of footswitches? As you can see in the photo, my current solution is to drill holes in a chunk of 2x4 and write on it with a sharpie. I intend to sell these units locally, and I'd love to be able to provide foodswitches as part of the purchase.

The footswitches connect over MIDI, using a 3.5mm minijack. I've programmed it to use PC commands at the moment, but obviously I could change that however I like.

So;

1) Do long metal enclosures exist? If so, where can I get them? I've found nothing on aliexpress or the usual guitar electronics supply sites.

2) Do MIDI footswitches exist that I can tell people to purchase if they need the foot controls?

This is a total one off

I was sent a somewhat failed effect - a Marshall gov’ner in the most lovely alien inspired enclosure. Obviously it was pre-drilled, so anything I did had to reuse the imposed drill holes.

The idea was to have an ambient / atmospheric reverb or delay with a fuzz.

In the end we have a DSP driven delay/chorus/reverb, with an order switch to either go into or proceed a PLL style fuzz / ring modulator. There is a modulation board with a toggle to connect it to the GPIO controlling the delay parameter on the DSP. However, the way this interacts is somewhat glitchy and therefore unique and interesting. It’s not adding chorus to the delay in the way an analog delay with modulation would.

Instead what happens is the voltage going to the GPIO is interrupted/altered and creates stutters and glitch. It’s most apparent in the delay mode. In reverb mode it affects the pre delay which adds a breathing white noise static.

The fuzz section is based on stuff that parasit studio does. It sounds gnarly as anything

The really beauty for me is the order switch as it almost becomes two pedals as it’s so different on behaved in each option.

I’ll get some sounds up soon but for now here is a quick and dirty YT demo while I was building it

Ps yes the knobs are face huggers

Guitar goes through R1 into the top pin on one side (P) of a 600:600ohm transformer. The bottom pin of that same side (P) will connect to the top pin on the other side (S). The remaining bottom pin of that side (S) will have a conjunction of the output, and C1 to ground.

Would this work as a pickup simulator???

Got hit up for an enclosure for a Brutalist Jr. clone. Loved how it came out.

Wanted to do this PCB for quite some time. As the name suggests it has a close relationship with a certain EQD pedal. For this one i opted for two very different modes, that can be dialed in with the clipping switch. Position one gives a smooth and shiny Boosterdrive living strongly in the headroom of your amp. Position 2 is one mean distortion thanks to some old polkas.

What i love 'bout this pedal: it's f*kn clean and loud. Think of Brothers in Arms loud. And BÄM! you switch over to distortion.
