along with the kit i got the 7809 chip. the holes on the board are to small for the chip to fit into. I want to make sure this is the spot for the chip.
Also i got 4 leds, on the parts list it says there 2 red led and others on the list just say led. im woundering if there all red, or does it matter where these go on the board.

Below is a picture of where the 7809 chip wont fit and where im confused on which ledgoes where

You've got the right spot circled for the 7809. If I gave you a larger one (the TO-220 package, with the big tab on it), I could either send you the right package that fits into the holes.... Or you could solder the one you have to the board, just make sure the face with the writing on it faces the left side of the board (metal tab sticking up). To double-check you've got the right orientation, follow the trace from + of the power supply connector to the leftmost pin of the 7809 (leftmost when you hold the 7809 so you can read the writing)

You also have the right spot circled for the LEDs. Most likely all of your LEDs are red unless some are labeled as being a different color. Just make sure the long lead goes in the square hole, and leave enough lead sticking up so you can bend it over to point at the CdS cell.

ive never had to deal with these CdS cells before. what do they do. and should the led be touching the CdS cell in anyway or just bent over the CdS cell/pointing to the CdS cell.

right the LED should bend over and point at the photocell. if they touch, that's great, or they can be almost touching, that's fine too.

I got the pedal completed. I plugged it in and tested it out and ran into a few problems.

Im getting power to the leds, but im getting no effects, no matter what switch i use or pot i turn. The only pot thats giving me anything is the gain, which is turning my volume up and down. Im getting no panning and no tremolo. i dont know what to expect with the board but the leds are turning on and slow dimming, then coming back on and repeating that cycle. is that correct. also when i plug in the power without any other cables going into the jacks the led will turn on, usually this wont happen unless a quarter inch jack is plugged in, right?

also im using a regulated 9v power adapter, and im not very familar with that 7809 chip, but is that regulating the power ever more with that chip soldered in?

Ill have pictures up tomorrow. im nearly 100% sure everything is installed properly, ive doubled checked my work throughout the build. seems like everything including the wires are installed right and the leds are lighting up, so im gettin power to the board, any ideas on what it could be?

Thanks,
RJ

Are the photocells shielded from all ambient light except the light of the LEDs? E.g. if it's in a metal box with the lid on, that should be enough. Also, you should see the LED casting a red spot onto the face of the photocell, adjust the two so that the red spot is centered. Send a pic, that might help

Sounds like your LFO is working (LEDs are flashing), and the gain stage is working (Gain pot changes volume), so the only thing left is the photocells...

Do the LEDs change their rate of flashing when you turn the speed pot?

As for the power, it should turn on when you plug the power jack in, it doesn't require a 1/4" jack to get power (that's a trick usually used for battery operated devices)

You might get better results if you either use an unregulated 9V supply, or use a regulated 12V, or replace the 7809 with a jumper from pin 1 to 3. But this isn't what causing your problem, it should still perform, just with less headroom.

I shielded the leds and photocells together with elec. tape and got the same result. depending on what setting i had it on the leds would very slowly dim and then come back and if i flipped the sync switched both leds would come on and dim at the same time.

The led on the right that points to the cds cell doesnt stay lit very long like the one on the left, the led on the right turns on and then slowly dims and the led next to the cds cell on the left is always lit, sound right?

Also when i plug my guitar into the R-in i then send a signal to one amp through R-out and another through L-Out, problem is no signal is leaving L-Out unless i have something going into L-in, i thought it should work with just 1 input?

Anyways, heres some photos, i had a hard time focusing on the components on the board so they might be hard to see. Plus theres alot of white wire so if you have any questions on what goes where, ask and ill try to get some better photos

It's hard to make out, but I'm pretty sure your LEDs are facing the wrong way. They should be pointed directly at the face of the photocell, and it looks like they are pointing off into space, at a right angle to the photocell. Does that make sense? The "tip" of the LED should shine onto the face of the photocell. You know you have it right when the LED casts a "spotlight" centered on the face of the photocell.

I just repositioned the leds to face the photocells and im getting the same effect. which is a very slow pann. im not getting any fast trem or pann. basically the right channel stays on for a second or two then shuts off, while the left channel stays on for a while then shuts off, both eventually come back on...

when i flip the trem/pann switch im not seeing much of a difference. The speed pot isnt doing much, actually im not seeing any difference when i change the adjustment of the pot.

Im using A voodoo lab power plus 2 to power the unit, i dont know if that makes a difference or not. ive also used other 9v power supplies.

The only way i can get this slow 'panning' is to run my guitar through my dd20 and run the output stereo out of the dd-20. this way i can have an input going into both channels of the unit therefore both outputs of the units will be heard. before that if i had an input going into the right channel and an output going out the right output and the left output then only the right output would be heard, no matter what i did.

Ill try to take better pictures or make a video but other then that im out of ideas. everything seems to be in place and the wires seem to go in the right place. i appreciate you taking the time to help me out, thank dan

Oh! I see it now on the PCB: you have to jump the two places where it says "SYM"! That would explain the speed pot having no effect.


As for using it as a mono-in, stereo-out effect, you need to plug the mono input into the Left input. The signal should come out both output jacks if you used the 5-pin switched jack for the right channel. What this special jack does, is that it connects to the left channel input when nothing is plugged into the right input jack. There also needs to be a wire between the left input and right input jacks, as shown on the panneur wiring diagram:
http://commonsound.org/panneur/pcb2.4.1/wiring.pdf

I can't make out any of your jack wiring in the photos, so if you think you have it wired correctly, send some good closeups of the jack wiring

How do i go about 'jumping' the two places that say sym. Do i jump them as shown below in blue or take a wire (as shown below in red) Also, do i just take wire to jump them together or clippings from other components..

index.php?t=getfile&id=62&private=0

Now im nearly 100% sure i got the wiring correct. i double check it once again.

Thanks again for looking over everything.

I got it figured out. i used a wire to jump the 2 eyelets where it said sym and sure enough everything works, sounds great. very please with the unit and the support here on the forum. thanks dann

Im wondering how i go about switching out the spdt switch that controls the sync function and adding a stomp switch instead, im guessing id need a dpdt stomp switch? I'd like to keep the spdt switch where its at and add the stomp switch, allowing both switchs to work.

Also im very intrested in adding a jack to control the speed of the pan via an expression pedal. Ive read that its possible but cant find any wiring diagrams.
Is it possible that i can control the speed with the exp pedal for one channel, then flip a switch and allow the exp pedal to control both channels simultaneously. If thats possible then id like to rewire the spdt that controls the sync switch to allow for this mod to happen

This isnt anything i wanna do tonight but in a few weeks or so, whenever you get a chance, i know your busy. i'd greatly appreciate this

btw im loving this pedal, ive searched for this for a few years now and i know alot of people who want one so hopefully you'll have some new customers ordering them soon.

Thanks,
RJ

You can just replace the sync switch with a SPDT stomp (or a DPDT, but just use half of the switch). Just wire the pins in the same order as if you were mounting it to the pcb. It would be complicated to wire it so both switches work, it would have to be like the residential wiring pattern for hallway switches (turn on/off a light from either end of the hall).

Expression pedal:
http://commonsound.com/other/genmods.pdf

Wire the jack to lugs 2 and 3 of the left speed pot

The sync switch allows you to use the left LFO to drive both channels, so you can use the exp pedal to control the speed of both channels. or flip the sync switch and the exp pedal will just control the left channel...

So i installed the exp jack and when i went to install everything into the enclosure the left speed pot wouldn't work, nor was the exp pedal. basically once the exp jack touches metal it grounds out the left channel, or at least the speed pot. i wired the jack to the lugs of the speed pot like i was told to.
I know everything works fine when the exp jack isn't touching metal. I'm also using the same jacks that came with the kit.

Should i wire the two wires coming from the exp jack to eyelets 2 and 3 on the pcb where the left speed pot is or is wiring it to the lugs of the pot correct. Is there a certain jack i should use?

It looks like the Neutrik 1/4 jacks look all plastic, ive never used that brand so i dont know if its metal and just painted black. Im assuming i need something thats like the dc power jacks and but for a 1/4" cable. If you know of anything a direct link would to a mouser part number or small bear would be great.

I found these links:

Thanks for all the help,
RJ

hmmm.. some neutrik jacks are all plastic except for a little metal tab that presses into the box when you mount it. This tab grounds out one of the lugs, which would explain your symptoms.

The neutrik jack I use for exp pedals is 550-10284

Awesome, works great. Im curious about if its possible to ground out the right channel when the effect is disabled. meaning, when im not using the right channel and the effect is off then no signal comes out of the jack, but when enabled the effect works... any ideas?

check your stomp switch wiring. Follow the signal down the wire from the jack to the stomp, across the jumper on the stomp, and back down the wire to the output jack.
