    Pythagoras cap sub

    Hey, I am building a few of these and I notice of all of the smaller ones in the pF range, why is the 15pF the only one with a tiny spot to install? And the 220pF and 470pF go in a larger spot? Are we supposed to use a larger box type/film cap there? .22n and .47n? Makes sense based on the...

    D3lay aka Pythagoras finished!

    Hey, I am building a few of these and I see you used the caps I think we're supposed to swap out. Notice of all of the smaller ones in the pF range, why is the 15pF the only one with a tint spot to install? And the 220pF and 470pF go in a larget spot? Are we supposed to use a larger box...

    Pythagoras Caps...

    I wonder about the caps used in the Pythagoras PCB. I see the 15pF which I assume is one of those tiny Ceramic round caps. I see the 1uF calls for the coated MLCC types, but what about the 407pF and 220pF caps. The spots on the PCB are much bigger than the one for the 15pF, Are these values a...

    ARACHNID DIED AFTER I TOUCHED SOMETHING...

    Oh I am! I'm about to buy a pythagorum w FV1, and an arachnid or 2. Going to grab a few module 8 and builder EEPROMS for comparisons and I'll figure the cheapest way to get the few FX I need. Thanks. And... STOCK. I get it. The effect is there, but the EEPROM might be written to change what's...

    Best value for a single FV-1 effect?

    Hey, is this thing on? I too use the Arachnid for like... 1, 2 or 3 effects. I just had a question answered where someone suggested I save the money on the EEPROM chips and just use the ones pre-programmed in the FV-1 chip. IS this right? I literally want to use the multi fx pcb for flanger...

    ARACHNID DIED AFTER I TOUCHED SOMETHING...

    Wow, thanks! I do feel the notes and descriptions of these circuits are limited on the site. This issue aside... I could be saving money on each build without the EEPROM chips? I literally use this pcb for Chrous, Flanger, Pitch shifter, all of which are apparently included in the FV-1 Spin...

    Id like to omit 2 pots and can't get it right...

    I just realized that I don't need the Mix pot to be replaced by any jumpers or resistors. It seems that with only the effect circuit coming that way and past R21. Unless the circuit is happier knowing it's all connected as designed? Maybe the chip wants to get that bleed off from the MIX pot...

    Pythagoras EEPROM options???...

    ARACHNID DIED AFTER I TOUCHED SOMETHING...

    I will remove the resistors in place and put the mix pot in to do just that. Of course audio probe! How dare you? Haha And... What's this about internal programs? Like there are already programed effects in the fv-1? And then the Eeprom works off of those? That's new to me, if so. Thanks!

    Arachnid Programed chips...

    Yes thanks! 0-8 is the same as 1-7. Easy as that.

    ARACHNID DIED AFTER I TOUCHED SOMETHING...

    Everything I use is from Pedal PCB. It worked until the jumper from the 8 pt rotary switch touched one of legs 1-4 of the eeprom chip. I replaced the Eeprom with another I had on hand and still the same. Best I can do for now is to replace chips one at a time.

    Id like to omit 2 pots and can't get it right...

    Hey, I'm always reading back to see what's what when building this circuit... R20 was removed because it's in the circuit for the dry signal, no? Not that a 1 cent part is breaking the bank, but I am trying to understand the circuit as well as modify it for my needs... I am confused even though...

    FV-1 EEPROM chips - Builder vs Module8 EEPROM for Arachnid build

    I AM making a few Stupid Sexy Flanders pedals. And of course will have sexy Ned in his Ski Suit!!!

    ARACHNID DIED AFTER I TOUCHED SOMETHING...

    Yes, the eeprom builder chip. Or module 8. But yeah that's the eeprom.
