Build Your Own Clone Message Board

Here it is, folks.

Please read the damn notes. It will save you a lot of time. More importantly, it will save ME a lot of time if YOU read the notes. RTFM, folks.

I'm also posting a straight list of parts values because people seem to not be able to extract that from either the schematic or the build document.



UPDATED on 8 Aug 2012 - Note the suggested value change for R9, which sets max feedback.

Awesome, i'll make sure to post some noob questions!

Thanks alot!

_________________

Shit, that's a lot of parts for a very small board!

_________________

Also what i tought.........., must be double faced......need components on both side.....

_________________

It's not *that* small: 2.25" x 2"

I don't think anyone will be putting this in a 1590A.

Oh yeah, I ordered this too
Thanks for the reminder Forrest drunk!

Help the Fez
If anyone find a sealed optocoupler that fits on Tayda, plz let me know

_________________

fyi, R20 on the build guide shows 10J. I know it's 10K thanks to the parts list posted above, but thought you should know in case it leads to confusion for others.

yeah, that's cause it's supposed to be a 10 JILLION ohm resistor

_________________

No one find anything for me, the tayda junkie?

I'm not sure what you are asking.

Tayda doesn't sell optocouplers, as far as I know. But their LDRs are perfect for this, along with a 3mm LED.

Then I shall roll my own sensai effsan
Frank lo!

_________________

So for the LED-LDR combo, I assume it doesnt need to be taped since its in an enclosure, but how far away from the LDR should the LED be? Would a clear ultra bright be too much if used?

never seen the datasheet for the Tayda LDR's, but folks often have the best luck with 3mm yellow or red LED's. Distance shouldn't matter too much, maybe a mm or two?

I've got the Tayda LDR's, so I'll try and report back when I build this thing.

_________________

I used Tayda LDRs when I was breadboarding this, and that's what's inside of the prototype pedal. I used 3mm diffused (not water-clear) LEDs. I don't think color matters on those. It shouldn't.

And no, there is no need to tape them up or use shrink tubing. Once the pedal lid is on and the jacks have plugs in them, it's dark in there.

Tape or shrinking tube is more Mojo though

_________________

Especially if you paint the tubing like PPG's "none more mojo" pedal

I know you said you didnt use a water clear LED...I have my board populated and am awaiting the momentary switch...but I DID use a water clear LED...should I swap it out now? Or will it be ok?

thanks

It's not going to hurt anything doc. I can tell you I recently built a delay and had a water clear in there. Couldn't really get things going. Put a diffused in there and bam all is well. Sort of worked counterintuitive, in my mind anyway, as I figured the water clear is so bright it will work.

Any sort of LED will work.

sweet, thanks guys.

i got this thing fired up and it sounds good...gets outta control kinda easy (repeats go forever and start sounding insane). I have a trimpot for r17, just havent swapped out the resister yet, so maybe that will help it.

whats the momentary switch do? Mine seems to do nothing? Might have ordered the wrong one (https://www.mammothelectronics.com/Prod ... e=800-1003)

thanks for the help!

the momentary switch is the 'freak the F out' button....basically


CJ/somebody else will have to explain what (technically) it does and how, but I will say I got the same switch, also from Mammoth, and mine works like the one CJ did in his video.....find his thread in the show-off section, I think his video is in there



And yes, the repeats are crazy cool

_________________

watched the demo...mine definitely doesnt do that...will take a look. thanks

When the switch is depressed, the delay time drops to very short, and then slowly returns to the longer time designated by the Time pot. The Decay pot controls how slow the return to the longer time is.

My momentary switch doesn't seem to do much of anything. I checked the switch and it's not faulty...anything in particular I should check first? Can post pics if needed.

thanks for your help!
