    Organ Donor Internal Level Trimpot

    Ok, so you used C16 + side to get to Vref. So if you did exactly as per the schematics, maybe you can try to add a piece of cardboard or plastic under your jumpers and resistor, to prevent them from shorting with a trace on the pcb. If it still doesn't work i would check for shorts in this...

    Organ Donor Internal Level Trimpot

    https://docs.pedalpcb.com/project/OrganDonor.pdf You mean these schematics i guess ? Why C16 ? it looks like it's in the power section. Unless C16 on your version is C14 here above ? Not sure what are the differences between your version and this one, but i would try replacing R15 by a...

    Oxide Distortion

    Oh yes, my bad ! I checked your pictures before posting, but i couldn't see It at first glance. It's only noticeable on the 3PDT top side, hidden by wires, like a shameful disease or something, but It's there, thank the diy goddess, glory to the Plastic Ring. So it's +250 pts, no penalties, of...

    Oxide Distortion

    -2500pts I know it's a lot, but that's how we learn, isn't it ? Your 3PDT was certainly supplied with a plastic washer, it's the golden rule. Can you tell us what you really do with it ? did you throw it away ? That would be -1000pts on top of the -2500...

    Lectric-FX Flintlock

    And i'd go even further : It's mega-fantastic. I know it can be a matter of taste, and it can depend on the rest of the equipment involved, but i really wonder if there is a better sounding flanger anywhere in this world. According to my humble experience, this circuit is number one, and by...

    Oxide Distortion

    Nice looking build ! I built it too and i really enjoy this one. i tried a diode mod, but the standard configuration is better than anything i could try. EQ section is great, it's perfect ! Edit : Can't see any plastic washer on your build... May i ask where is it ?

    How to load effects into EEPROM ?

    Off- topic quick question : Something a little scary just happened to me. I was soldering a socket pad on a pcb, as usual, and something blew up suddenly right in front of me while i was doing a solder joint. Like a tiny micro-firecracker. No harm done, no visible signs on the pcb, the...

    SOLVED Aion Xenotron : Manual control issue

    If i had to do it all over again, i would be more cautious with the rotary switches, and i would use wires instead of jumpers to connect them to the main board. I wish you good luck !

    How to load effects into EEPROM ?

    Hello, I am building DeadAstronaut's F-24 Multi-fx project. It's almost done, and i suspect the two EEPROM sent with the kit are empty. But the project includes a 6 pin header to access the EEPROMs...

    SOLVED Aion Xenotron : Manual control issue

    Wait ! I still have a big expensive ring modulator with an issue with the sawtooth VCO waveform : https://forum.pedalpcb.com/threads/neurotron-ring-stinger-sawtooth-waveshape-low-volume-no-modulation.20472/

    SOLVED Aion Xenotron : Manual control issue

    Thank you so much ! A small sheet of paper greatly improves the Manual range, you are right ! I could have done more damage to the circuit by looking for the issue, so i'm very grateful to you ! I also could have wasted lots of hours before finding this led problem. I am so relieved.... this...

    SOLVED Aion Xenotron : Manual control issue

    Hello, this is my second troubleshooting post on this circuit : i thought it was ok, but it's not compared to other builds. https://aionfx.com/app/files/docs/xenotron_documentation.pdf The obvious issue is that on my build it is much harder to dial some good modulation settings, compared to...

    Aion FX Xenotron (Lovetone ? Flanger) Build: Weird behavior of ring lift, stereo/mono, and bypass switches.

    i think i wasn't clear, sry. The Input Gain control does its job, no issue there. I have distortion appearing during the Manual pot's rotation (1rst half). I noticed it when using only the Time output. On the Mono output, it's there too, but less noticeable because of the wet/clean ratio. I...

    Aion FX Xenotron (Lovetone ? Flanger) Build: Weird behavior of ring lift, stereo/mono, and bypass switches.

    Thanks a lot for taking the time to record these samples ! I think my build is able to produce some similar sounds. It's probably quite close to total completion. Now that puntygrapes mentioned it, i guess i can hear something like a delay being modified when i turn the Manual pot within the...

    Aion FX Xenotron (Lovetone ? Flanger) Build: Weird behavior of ring lift, stereo/mono, and bypass switches.

    Is there a point in the Manual rotation where your modulation fades away ? Or is it supposed to work through the whole rotation ?

    Aion FX Xenotron (Lovetone ? Flanger) Build: Weird behavior of ring lift, stereo/mono, and bypass switches.

    Thanks for the demo ! You have modulation with Manual at noon, which tells me something is really wrong on my build.... Your circuit sounds much better than mine. Congratulations for this difficult build !

    Median Compressor PCB - Available Now!

    "Median compressor" ? I really thought PPCB was releasing a clone of Guyatone PS-21 like Aion's Meridian compressor !

    Aion FX Xenotron (Lovetone ? Flanger) Build: Weird behavior of ring lift, stereo/mono, and bypass switches.

    Using only the Space/Mono main output, i don't notice any change with stereo/mono switch. No volume drop with the Ring switch, but when set upward, the Time modulation is cut off the mix, i only have the clean signal, and the space/tremolo modulation working. However, using only the Time output...

    Aion Meridian guitar to bass switch

    Understood, thanks ! Longue vie à Feral Feline ! Edit : just did this mod. I first used a 470k resistor across the outter lugs of the B1M Sustain control, and 27k at R8. I had a little statics and scratching noises at the end of the pot's rotation. I added another 27k to the 470k and now it's...

    Aion Meridian guitar to bass switch

    I count 7 values that change between both version. https://aionfx.com/app/files/docs/meridian_documentation.pdf I would look for a big 8PDT toggle, or 2 x 4PDT to add these parts to the circuits. This way way you will have the two versions in a single box. If you are looking to modify a...
