Pedalpcb.com demos ?
« on: January 24, 2018, 02:46:14 PM »
I cant seem to find any pedalpcb.com fv-1 Demos on the web :/
As anyone build one on this forum ? Do they sound any good ?

Yes, it sounded awesome. Plus, Rob is a great guy when you are stuck or get any issue with the build. I will try to make a quick demo this weekend for my finished Glimmer. It's a definitely a go-to pedal for the post-rock style/worship music.

Cool :) i just ordered a fv1 chip, Organ donor pcb and a phaser 2  pcb just to get the free shipping :D
Really curious how diy digital pedals sound ^^ hope that he makes more. Weird how some of the layouts of fv1 chip pcb are identical... all that must be different is the program on the rom chip. NEED a digital synth pedal !!

Just noticed he is coming out with a multi effect. Curious about this one. http://www.pedalpcb.com/product/octagon/

The Organ Donor does sound awesome, very comparable to the EQD organizer

Wow, tempted to build one actually

I'd kinda like to build the Organ Donor, but I've noticed that the schematic/build notes still haven't been released. So, I dunno.
I own madbeanpedals (duh). I am part owner of Function F(X).

Wha, somehow Ive never watched a demo of the organizer?! It sounds fantastic. Id like to see the documentation as well. This one might stave off my need to finally pick an EHX 9 series pedal up.

Interesting. Wouldn't be difficult to turn that 8 effect pedal into a 15 effect pedal, would just need to wire a switch onto the ground side of that 10k resistor under the EEPROM.

I also just realized how many of their PCBs are identical save for the EEPROM they come with. Fascinating. Makes sense I suppose, why bother designing a new board if its the same architecture.

Just emailed Rob and he said it uses the 100k linear pot to change between the presets. I asked him whether there is a way to trick switching nicely between the presets. Perhaps, 8 poles rotary switch.

Yeah he has a little microprocessor on the board that will play the role of the 3 toggles the FV-1 is designed around (the ATINY85 chip). So like, 0-12.5k = (0-0-0), 12.5-25k = (1-0-0), 25-37.5k = (0-1-0), etc etc etc. (I mean the resulting voltage from those resistances, but same diff)

In theory you could set up the same deal with a rotary and resistors in series. It would be a bit of a pain to fit in the box though, not a lot of room in a 125 to spare.

What I meant about the 15 effect thing was, the way he has it set up is it will use 8 effects from the outboard EEPROM chip. BUT, the FV-1 also has 7 (plus one blank) effects built into it. If pin 13 sees a 3.3V signal, it uses the stuff on the chip. No 3.3V, it uses the onboard stuff. To do this, you wire a switch on that 10k resistor under the eeprom, flipped up the juice flows to the FV-1, flipped down it goes to ground.

This would give you all 8 effects on the EEPROM, plus the 7 defaults. Super simple.

Also, because he was nice enough to use a through-hole design for the EEPROM, all you need is to socket it and you could swap out effects for the price of a new chip. All manner of fun patches out there to play with, or design your own.

(Ah screw it, I just bought the octagon and a chip. Ramen for a week it shall be!)

Pentadecagon, here I come!

Wow, that was escalated quickly.
