I sent out a couple of press releases today, hopefully we can get some more publicity and bring in more bids.

I took a quick look and it looks like the circuit is good, but a few values are off:

R5 should be 100k

R23 and R24 should be swapped: R23=22k and R24=10k

I picked this fund out of several options, but if anyone has a suggestion otherwise please feel free to enlighten.

I've been posting these links to charities around, just thought I'd post them here:

Yeah, it's a DS-1:

This may (or may not ) answer some questions. Take a look at 3:29 and 5:23 and 7:05:

Maaaaaan, that looks sharp. How do you like it?

It's pretty awesome Jimi. Devo is probably the most famous user. It was taped to the guitar to use it and change settings.

Nice build!

And here's Mark with his FA:

Very nice!

I like how the tree goes over onto the sides.

What type of goo did you use to hold the LED in place?

Very nice!

And bonus points for the resistor teepee!

Guess that was my question....In the ORIGINAL schematic provided, I am assuming that is the view from below....how do you know for sure? OR is the assumption that all pots shown are 'in' the enclosure and therefore can only be viewed one way, IE from below....

I am guessing the view is from below based on the way it is drawn(that is why I numbered it the way I did) AND this reference from Beavis Audio seems to suggest the same, to my little mind. Am I wrong?

Appreciate it! This has always confused the hell out of me...pretty sure I have driven myself nuts before with this!

I don't know if this will help or not, but manufactures actually specify which pin is which in the datasheets:

Sorry for a hijack here - Dan, did you replace the single turn trimmers on your Glasshole with multi-turn trimmers? Those kind of look like Bourns 3266w? Did you need more precision, or?

Thanks!

Hi!
I used the 10 turn trimmers because that's what I had on hand. This project is pretty easy to dial in. Set the brightness trimmer (1k) about halfway. The offset is the important one... Set the depth pot all the way CW, Feedback CCW and rate fairly slow so you can see the full "sweep" of the LED by the LDRs. Of course this has to be done in close to complete darkness so it helps to have a light on your multimeter. Set the "offset" trimmer (10k) so the LED gets very dim (almost off) but not all the way off. Then you can tweak the two trimmers to taste. I found that adjusting the offset so the LED doesn't turn all the way off is very important.

Thank you!

So far, it looks like there are some traces overlapping in the lower left. The 5088 has its emitter and base connected, and the 1k and the 10k shouldn't be connected. Again, it's because the traces are crossed.

Also the 22R should be a 220R.

Maybe this will help:

I actually designed a board for this last year, but I haven't tried it yet. I'm pretty sure it'll work with roll your own vactrols, so the board is set up for LEDs and LDRs.

Maybe I can give it a go soon. I haven't been able to do any builds for a while but that should change soon.

If it works, I can see if I can get a batch of boards made for you guys. No guarantees, I've got a few kinda difficult things going on right now, but I'll give it a try.

There are a bunch of organizations that take instrument donations:

The Maryland Symphony Orchestra also takes donations, including guitar, although I didn't see on the site if they take electrics. The instruments are "for use in general music classrooms" so they might take electrics.
