« on: January 05, 2009, 09:12:36 AM »
Hi Guys

I'm workn' on the looper pedal Dirty Sam but i couldnt recognize the wire connections of his circuit. (like where the sw connections go ?, what's p1, 2, 3 ???)

Need Help (esp. experinced guys)

Thanx

Merhaba!     :icon_biggrin:

You need to provide a link to the project in question.
Sincerely

Ok. I've looked into the project and I liked the sound of it.
Basically the project is unbelievably cool but it's presented in french on a french homepage refering to a latin american homepage
in spanish. I suck on both french and spanish...    :(  as well as turkish.

1.
On the french link is a mod for frequency control. I'm not going to adress this at all.

2.
...i couldnt recognize the wire connections of his circuit.
The board has: input, output, fx send, fx return, 3 potentiometers wired as variable resistors ( 2 connections ) and finally two mode switches of sorts.

In/out
Connects to dpdt switch as this link top right.
http://humano.ya.com/guruzeta/Guitarra/dirtysam/analog.html
InFX/ OutFx are solder pads on the PCB. That switch also has a lug named in MBP, which is where the millenium bypass connects if you're going to use it. (search the forum or google)

Fx send/rtn
http://www.muzique.com/lab/truebypass.htm
top drawing
connects to pads on the PCB marked Fxli/Fxlo. (connects to the middle lugs on the dpdt switch. the two outer lugs on one side is bridged the two outer lugs on the other side goes to fx send/return jacks respective (fx send has a cap! ).

SW1 - "Safe" switch. A dpdt on the digital part of the circuit. 1st pole toggles an LED on/off, center lug to R/LED, this is not a part of the pcb.
2nd pole goes to pcb marked sw10(center lug) and sw12, one lug free.

SW2 - "Record/Play" switch. This has two suggested ways to wire it up. I'm going to explain the spdt way.
On the digital part of the drawing. Middle lug connects to sw20 on pcb. The outer lugs go to ground and +5V respective.
On the analogue part top/right... solder pads connected to C5 and R8... Bridge! ( marked sw20b and sw22b )

Potentiometers
P1. Don't know. I don't do 386's. Period. But it connects to wiper and either of cw/ccw. try one option and if it works in reverse just change lug keeping wiper connected and bridge the leftover to the wiper lug.
P2. Connects to wiper and clockwise. Bridge wiper and counter clockwise. Volume will be at it's maximum with pot fully clockwise ( as usual, feedback resistance at it's maximum.
P3. Connects to wiper and counter clockwise. Bridge wiper and clockwise. Cutoff will be at it's highest with pot turned fully clockwise.
...that's about it...    ???    :)  -lycka till!


This is actually a project I could imagine building myself one day but...
that goes for a lot of the stuff around here!     8)

Hello
I'm a french native speaker, don't hesitate and ask me if you do not understand something on this project, i'll try to translate !

I suggest Google Translate for translateing pages. It has good results...

By the way now I understand the connections was so easy. I plan to build it short time. I'll show the results

And thanx Oskar very much...

Men! Give me anyone a nominals of resistors and capacitors, please! The page with this doesn`t work...
