Can anyone tell what the green line means between the two 1/4 jacks. I've bilt this thing twice and can't seem to get it to work. I am pretty sure I am screwing up on the wiring of the jacks

Re: Wah pedal
That is the wire connection for Bypass mode when you toggle that DPDT (Double-pole-Double Throw) foot switch. They should have shown the switch connections and the Phone jack connections so you will wire them up correctly.
The jack will have Tip, Ring, and Sleeve if the stereo phone jack, the Ring is used for switching the battery in the battery when you plug in the Mono phone plug. The Tip of the pone jack is connected to the Common terminal of the DPDT switch.Last edited by budm; 08-16-2013, 02:08 PM.Never stop learning

Re: Wah pedal
All they show is what I posted. I can get a signal through it using a signal generator, but I can't seem to get the wah effect. Well back to the benchComment

Re: Wah pedal
Seems to be working just fine in LTspice. Are you sure all your parts have the proper values, etc?
Edit: And then there's budm's thought about (im)proper jack wiring, perhaps...Khron's Cave - Electronics - Audio - Teardowns - Mods - Repairs - Projects - Music - Rants - ShenanigansComment

Re: Wah pedal
I used a 47k in place of the 48k but I didn't think that would make a big difference. I still think I either wired the jacks wrong or the pot. I've looked at it so long I wouldn't see it if it jumped up and bit me. I'll try again in the AM. If any one has any ideas please let me know. Hey Khron666 when you did on spice did you use the jacks and pot. If you did is there a way to send me or post a copy of it.
Thanks everyoneComment

Re: Wah pedal
Pot yes (as in, two resistors), but "of course", no jack

I have two TCL A30 phones.
Old Phone: This phone worked fine for years, then stopped charging If you plugged a charger into it, the phone would make the charging sound, the phone would tell you it is charging, but the battery icon would not have the charging symbol in it and the battery would not charge.I tried new battery, same behavior.
New Phone: Works fine, bought as a donor board to try and repair Old Phone
My interest here is to repair Old Phone, using components parts off New Phone if needed. I am not interested in replacing Old Phone with New Phone.... -
To you programmers out there I want to know if it is possible to put a new OS on the Sonim XP5s phone? I only need this phone to make calls, receive calls, have a list of contacts and be able to call voice mail.
I bought this phone new Sep.2021 as an unlock phone from a third-party seller. The phone worked fine until Jan 2022. I then had intermittent problems with the sound setting resetting itself. One of the settings, outdoor, would go to silent all by itself. When in silent mode it does not indicate a call has come in. I missed very important phone calls. All the other setting in sound... -
OK, this is a long shot. I got this sewing machine cheap because it's end of line, ex-display, and had no pedal. The genuine pedal costs £60, while Ebay knock-offs go for around £15. So I went for the knock-off, it doesn't work, and I'm not sure whether it's the pedal or the sewing machine that has the problem.
Now this is an electronic machine, unlike the old fashioned sort where the pedal was a big resistor in series with the power to the motor. Here, the pedal is just (I think) a variable resistor fed with a 5 volt supply, and limited to a current of 5 milliamps. Assuming that... -
Hi all,
Got this smart phone free from a guy who dropped it hard until the lcd display cracked with no seen display.
Opened it and found the display ribbon cable partly damaged. I charged the phone full in 2 hours time, the led red light turns to green indicate full charge.
Then i use a usb cable connect the phone to laptop but it only showed as media player with firmware version. Too bad there is no option to check folder.
Does anyone know any method to check if the phone is working good? Looking forward for any advice and help possible.
If tested the... -
Good day folks. I had a little f-up over at my new shop today and it made me pretty angry, but at the same time it determined me to try and figure out what could've happened there. This is only going to be a speculative discussion since I don't know the exact layout of our network, hence I don't know what's going on past our room. So:
The repair shop where I sit is situated in a remote building down the street from the main building. There's a Cisco IP phone in this room, a 7911, like the rest of the company uses. There's obviously some sort of networking going on between the two...
