Cool man, that's a good one. My first was a merman.

General Questions / Re: How do you read Alpha rotory pot markings?
« on: July 03, 2020, 01:11:52 PM »
Thanks, that sounds right. It all measures out like you said. I think I confused myself into thinking the printed code actually meant something. I got a bag of random rotary values and the other code values didn't match up to what I thought but all the 3P4T ones are marked 4J3 which seemed reversed.
I'm all straight now thanks!

How do you read the poles and positions from the code on the back of Alpha rotary pots?
I have a 4J3 pot as seen in pic. Does that tell me its 4P3T or 3P4T? Thanks!

Hmm, not sure... I'd reflow the switch and all the silicon clipping diodes and possible the 220p cap next to pins 1&2 of the dip socket. What diodes are those and where'd you get'em?

Looks pretty clean to me and LEDs look like they are in correctly. If you have another dual opamp, you might try that.
Also, does the Fat control work? Does the drive pot produce a volume increase when turned up?

From the VFE website: "There is an internal DIP switch that sets whether 12:00 is clean or crunchy (via LED clipping),"
How is your internal dip switch set on the LED side? If it is in OFF(down) position, then it will be a clean boost when the SLA(clipping) knob is set to noon.

General Questions / Re: Pepper Spray build docs mistake?
« on: June 28, 2020, 01:28:37 PM »I'm sorry, I thought I had corrected that. I will do so today.
The transistor is 2n3565.
1n695 is the OG diode. Subs are 1n34a OR BAT41.
update: docs fixed
Awesome, Thanks!

Open Discussion / Re: Pedalpcb.com demos ?
« on: June 28, 2020, 08:40:36 AM »
Sorry to dredge up an old thread.
It would be great to have demos for some of the fv1 stuff. I still haven't been able to find many if any. Im hoping to pull the trigger on getting an Arachnid and using the eeprom builder for the patches but it's hard to choose which ones since I can't hear them. I also noticed that the bitcrusher patch is not available in the eeprom builder list.
Btw, The fact that any of this is available at all is super fantastic

Actually... Looking at the GGG schematic. Both statements are correct.
It's a 10 stage phaser with 2 fixed notches and 3 variable notches.

Sorry, I guess I'm thinking of something else with fixed stages.
The elecrosmash phase 90 analysis says the following:
"The effect is more dramatic by placing more than one notch. MXR Phase45 has 1 notch, Phase90 and Univibe have 2 notches and Phase100 uses 3 variable notches"
https://www.electrosmash.com/mxr-phase90
It also goes on to say:
"The LDR Light Dependent Resistor used on MXR Phase-100 and Univibe is linear and easy to use."

Any chance of getting the V2 switching board as an Oshpark share?

General Questions / Pepper Spray build docs mistake?
« on: June 27, 2020, 06:19:59 PM »
The build docs for both the Pepper Spray projects have this:
"1n695 or, 1n34a"
"2n3965 or, BAT41"
"You can use BAT41 diodes as subs for the 1n695"
And then it goes on to talk about the 2n3565 rather than 2n3965, but 3965 is what appears in all the diagrams.
So...
- I can see from the pic in the doc that the appropriate sub for the 1n695 is indeed the BAT41.
- I think I remember reading that the 3965 was a mistake and it should be 3565, but just want to make sure.
- Is the 1n34a just a mistake or is it actually a sub for something?
