'LIGHTWAH'

[ppaappoo]

Great!! 
then at the end you used a sine LFO?

[deadastronaut]

yep!!

[askwho69]

hi all one question. . how do differentiate this wah and wah that has inductor?

for me.. wah with inductor has stronger and so WAAAAAAAAAA"YISH! rob bout you how will you differentiate your wah with th wah that has inductor?

yeah i agree, much stronger wah...but hey, you can just use that wah with an lfo too...i think this will be a great accompaniment to a 'fasel/inductor/ wah....
which most people may have already....or a great pedal board friendly wahl if you havent...(tiny amount of pedalboard real estate ..)

you could just buy a wah and a tremolo of course......but wheres the fun in that?.....i get my kicks out of throwing stuff together and getting a good sound
not by merely 'replicating'...but a little innovating....or just simple @#$%ing around....if it sounds cool...thats good enough for me..
it also annoys the hell out of my missus...

Will there be a final layout and pcb for this project,

Thanks,
Ronnie

[deadastronaut]

no!...

yes in time...

[deadastronaut]

heres the latest schematc, with the modded wah...and arnouds sine lfo....bit of a mess but you get the idea!..

ignore the depth pot....i thought id try a depth by dimming the leds...the pot should be on the positive side if anything..

[ppaappoo]

Excellent, may by the depth pot must be 10k and R12 1k

[deadastronaut]

Excellent, may by the depth pot must be 10k and R12 1k

so the 10k pot on the positive side of the leds, and the 1k on the neg to ground yes?...

i'm knockng up a vero of the wah...and a seperate lfo vero too...just to get it going for now and see how it behaves when wired up...should be ok...

theres definately no ticking issues with arnouds sine lfo...great!..  

[ppaappoo]

so the 10k pot on the positive side of the leds, and the 1k on the neg to ground yes?...

It's the same!

[deadastronaut]

ok...sorry being a dumbass again!..

i was jamming over some satriani backing tracks earlier with it...sounds very authentic on summer song...lead!... very nice.

[deadastronaut]

ok heres the vero of the wah section...anyone see any problems with it, ive checked it over, but you know how it is!...
sine lfo section coming next...(i'm trying it all out on vero before going down the pcb route!..test test test!!!!!....



and heres the lfo section.

[deadastronaut]

to anyone thats remotely interested...
right i thought sod it...i'm doing a pcb now...ive done the wah side and its very compact.(to me)..so the lfo should make it still quite small...not 1590a for sure..
but very 1590'able...this is my first go at a proper pcb though .i usually mess with vero..but its @#$%ing me off....so dont laugh ok!..

in o----o-----oo-----o  out. thats it!.. .....to be continued..........

[deadastronaut]

ok heres my first pcb .........messy i know...and r8 needs to join with c3...but its late and i'm knackered.. and it took hours to do...

i like the wah section.... the lfo section could do with some tidying up a bit...(talking to myself)..again....

god knows how you guys can do pcb's without lots of jumpers.....i still had to do 2...hmmmm....

other than that, what do you guys think?...anyone?..

:O




NOT VERIFIED!....DO AT YOUR OWN PERIL!... .....off to bed!..yawn!..

[ppaappoo]

very nice, as is the response of the LFO? I mean the speed range is similar to a chorus or phaser?

[Hides-His-Eyes]

rejig a bit and use R4 to jump that trace


the other jumper looks a bit more inevitable

[deadastronaut]

@pappoo, the speed range is pretty good...slow-fast...

heres a clip of the slow fast ok...

@HHH. hmmm...its a pain to do coz i'm using version 1, and it wont highlight the selected trace,(and there are lots) even though it highlights the solder pads when selected...the @#$%er

might have to copy/redo it into version 2 so i can easily jiggle stuff...

cheers.

edit:

ok ive sorted those little bugs out...i also added a protection diode, and a 100uf  for power filtering...just for the hell of it...(i always have one on my breadboard too)

what do you think guys?... 1 jumper aint too bad considering its my first go at a large pcb..

here we go!..

[deadastronaut]

whoops double post...

oh well while im here , heres a distortion clip slow-fast....

[ppaappoo]

if you want I can help by making a PCB with Eagle

[deadastronaut]

cheers pappoo.

yes that would be cool., ive got my missus to print this one for me, i;ll try it and see how it goes....thanks.
