The 2M2 should at least be 'preferred' (C22938). There are a bunch of TVS diodes that are basic/preferred also (C2990493 for example), they're under "Circuit Protection" and not "Diodes" of course. There are also a bunch of zener diodes that are 'preferred' and skip the loader fees (e.g...

This is an interesting discussion! I had a couple of comments: - In terms of footprint, using castellated pads is pretty interesting, but it does take a lot of real estate. It might be interesting to try some different layouts - I was thinking of doing something like this with pin headers...

I can't read the schematics, they're too downscaled to make out any words. My guess is layout problems - IIUC, ethernet requires pretty careful layout (matching differential pairs, impedance matching). Do you have a datasheet for your ethernet controller? Did you follow the layout advice...

I haven't built one of these, but I doubt it. 800mA is a lot for a pedal. As mentioned above, audio probe tells you lots of things - go through the audio path of the schematic and find where the music goes to die. If that doesn't help narrow it down, it might be better to post a new thread, or...

re: if KiCad is better or not - hard to say for sure, I haven't used DipTrace. Some things that I like about KiCad: * Free (unlimited pads/layers) * Open Source (so if you're stuck trying to figure something out you can investigate the code or just fix it yo'self) * Pretty big plugin ecosystem...

Good idea on the front/back printing thing! I have a bunch of faceplate layouts that use the same drill pattern so if I match those up I could combine them this way. I'd rather have 10 faceplates that I could use for either design than 5 faceplates of each. (Although I guess there are benefits...

Also, the update for 10.0.1 is out now -- there are some bugs in 10.0.0, especially related to plugin management, that were pretty annoying. (They're turning off the SWIG API in KiCad 11 so I've been trying to get plugins working using their new IPC model - but the IPC plugins don't show up in...

I’ve spent the last month or so hacking away at some personal projects to make building stuff go faster. They’re probably a little rough around the edges since only I’ve tested them, so I’m happy for any feedback (PMs here or issues on GitHub, either way!). I hope that some of the builders...

I'm just giving you a hard time - I'm sure this is fine. I figured it was paper towel / kimwipe lint. Looks a lot better than the crusty flux on mine. There looked like another tiny cut lead nestled up against a solder joint east of the bottom silkscreen of the pot. It's hard to tell for sure...

Maybe a small stray clipped lead that got pinned between the pot backs and the board? (I've definitely had a lead escape into the enclosure before when clipping the LED leads at the end of the build, since those usually have to be soldered in-situ)

Okay - github repo updated w/ templates. I re-installed KiCad 9 and did the edits there so that the templates would be KiCad 9 compatible in case yall haven't upgraded yet! To use the templates, copy them into your ($wherever)/Kicad/<version>/templates/ directory. LMK how these work for you...

Aliexpress's search functionality sucks. The same store does have these in XH as well (for the princely sum of 65 cents for a 4p connector) https://www.aliexpress.us/item/3256807910270391.html?

Yeah, if the floor is $1 that's pretty expensive. These are what I ordered, 50 cents/ea. https://www.aliexpress.us/item/3256809225459051.html? You have to pay shipping but the shipping charge was still $3.37 even after adding 10 to my cart. IMO 50mm is kind of the floor for the length of these...

Oh I'd never thought of this, I like this idea. Just bend into a Z shape or a U shape and solder that way instead of dealing with ribbon cables. This might even be an acceptable replacement for the JST cables between the footswitch and the PCB.

I'll update my github repo with this layout as the template, since it seems to be the best-fitting one so far. The jack selection is kind of a pain. If I leave the footprint holes large like this, it fits the Rean/Neutrik NYS215 (Tayda A-7115) really well (and the A-3575 might fit, too) but...

oh, and for the knobs thing - I guess you could use the D shaft pots, or splined shaft pots, and use push-on knobs rather than fiddle with the set screws. Has anyone here tried that with any success? (I think the Tayda selection is much less for those types of knobs and pots, but maybe it's...

Nice soldering, clean board. Do you have an audio probe to see where the music goes to die?

gawd I haaatee soldering wires to things. I use JST connectors wherever I can. You can get pre-wired cables from Aliexpress in 50mm size (good from daughterboard to main PCB) and 100mm (good from IO board to daughterboard). Are they the *exact* size you need to have the super-finished look...

Eyeballing those footprints, I'd say all of the passives are 0805. Here is an 0805 cap against the SOT-23 transistor - you can see that the middle of the pads are pretty close to the same. The diode is a SOD-123 (or 123F or 123FL, they're pretty equivalent in my experience)
