ill suggest the other 47k for v ref, so the 1st one won't be lonely... :icon_frown:
nothing says forever like a solid block of liquid nails!!!

Richon, I like your idea!

From the 9V (where the trimer is) a cable to an IC (TL072) for a future LFO!!!  :icon_evil:

please enter somewere on the schematic, on my behalf, one resistor 47k ( I like its colors  :D) as a starting point of Vref, needed for the above)


Is this right?



Also, is the 1N4147 cathode supposed to go to the BJT's base?

EDIT: Added my page 2 contribution  :icon_twisted:

Hides-His-Eyes

He wanted the two 47ks to GENERATE Vref at the op-amp (needs to have no cap on it)

Convention creates following, following creates convention.

With my contribution:


Is that how you guys wanted the Vref?

phector2004

I think the "47" values are very popular because the resistor band colours are complementary...

I don't know much about wahs, but it looks like you guys are making a filter of some sort... seems like this is going to be an auto-fuzz-wah   :)

darron

Great idea. The potential to desIgn the worlds best distortion is here. Don't know if it's a shame or brilliant whatever the circuit is is becoming something crazy!

Keep it up guys! I'll watch this one. Hopefully something cool to build or contribute to!



Here's an easy one. Please add a 22uF cap between the 47k's vref to ground for me for smoothIng...

Thanks, Darron!

I figure 1000 minds are better than one. Hopefully we'll all be able to learn something new from this.

JKowalski

Wow, this is interesting.

Yeah, but 1000 minds on totally different tracks?   :icon_lol:

And a transformer... Ohh, I'll wait till the next page...

2N7000 drain to tl072 pin 1, gate and source to vref
I forgot what I was gonna say here.

I'm actually REALLY hoping it works whenever it's done... if ever   ;D

I don't think I should start a new thread....

but I think we should start, on a long term base  ;), also to think about a name for it... or you guys think it's too early ??  :D

This is already starting to look like it could become a really cool frequency-dependant tremolo, if the TL072 becomes an LFO and ends up connected t the 100K pot.

let's add a reverse polarity protection so the first step, 1n4001 with the banded side to the positive and the other side negative :D

How's this looking? Hope someone ends up doing something with the 1044! +/- 9V, maybe? Voltage doubler? Tripler?  :icon_twisted:



Armando, what do you mean exactly? More focused designs?

arma61



No I mean the name for when, if ever, it will be completed  ;D

and I would like to suggest... if this will ever become something real (may be with some corrections) we all do it in the same box with the same design layout knobs etc..  and the "diystompboxes.com" logo too!!  :D

Sounds like a plan, but only if a certain forum member etches the enclosures... So they come out all nice and uniform  :icon_lol:

I don't know what the end-point will be, maybe when someone gets it working with tweaks? We can argue over the name then.

vendettav

I agree with the logo idea. I wouldn't mind a DIY/tranny logo on it ;)

as for the name, we better see what's the final effect we are getting

cool idea but already f****d i think
