this might be a really stupid question , but where do I connect negative?

Ground is the bottom left pin on the chip.

thanks!

It's working but it doesn't really sound like I expected it to. it just makes one constant tone, and you can change the pitch, am I correct? or did I make a mistake somewhere? I doesn't sound very much like that sound clip from the kaustic machines site. I was expecting random stuff

On the clip on the machines website i'm weaving my hand above the ldr like a lunatic... 
You can do fun stuff with this thing... add an ldr in series or parallel to one or both of the pots, make them switchable, have an ldr controlled by a lfo (tremulus lune?)... etc...

does anybody want to attempt to make this project a guitar effects pedal, kinda like how an envelope filter controlls a wah, you could convert the signal from the guitar to similar toned atari beeps? I think it'd be kinda cool to experiment with playing some atari game theme songs using a pedal like that and i reckon it'd be a popular novelty pedal, i mean it's a pedal you woudln't be able to buy so surely many would build it.

I still think I did something wrong, I can't get double tones like you have in your clip,  at 26 secs you get a low tone and a tone an octave higher, with tremelo(ofcourse that could be done with a tremelo pedal). I just get a very tiny variety of 1 straight tone. More like a normal tone than an atari tone. Also one of the other pots only does veery slight pitch shifting or none at all, unless I turn it completely full then it goes up a tone in pitch.

[Brett Sinclair]

There could indeed be something wrong with your circuit... it should be able to give you a range of "shifting" sounds and both pots should be quite interactive.

I built one today from Choklitlove's Layout, it is now Verified. Uses a 556. and other than the pot values, it is right on the Mims Schematic.

can someone make a layout for the version with 2 555's?

[MikeH]

Has anyone messed around with the idea of putting this in a box with another effect and using some sort of "blend" control to mix it with a fuzzed out guitar signal or something to the effect?

[$uperpuma]

you could probably mutate the single oscillator in the Uglyface to a dual oscillator. IT would be a little tougher to manipulate playing guitar and turning two knobs would be hard... even a little more ridiculous, you could use an expression pedal for each osc. controller... ORRRRR you could use an LDR for one and an expression pedal for another.... too many possibilities...

[Bernardduur]

I used two LDR's and it works great!

this was posted earlier in the thread:

Heres a layout for the thing using two 555s based off the schematic on the previous page

[Psych0F0x]

I still can't get mine to work right. Looking at the 2x555 layout: Pot B doesn't do much, the other pot changes pitch. Level acts a bit weird. Help??

[Gila_Crisis]

i built one (with the LM556) and tried now. it work! pretty cool noise maker 
i like it, now i must only find a little box to put it in a solder the last few things.

[Meanderthal]

 Just built the dual 555 version... Lotsa fun! One thing to mention though, on the layout posted by seljier pin 8 of Ic2 should go to +9v! Check against the schematic, you'll see what I mean.

[Snuffy]

I've built two and they both sound pretty good execpt for the second pot on the 556 layout does most of its stuff in the first 1/4 of the rotation, the rest of the way it just farts out.
I'm going to experiment with different pot values to get a better range

[Meanderthal]

 I used 1m for those. They do stuff over most of their range.

[Gila_Crisis]

this is the one a build!!!!

today i runed it thru my pedalboard, and messed a bit with all the effects (delay, lfanger phaser, ring mod and wah) preatty sick noise maker

[$uperpuma]

i built the etched apc and etched uglyface for a circuit bending buddy of mine and he says hes gotten somegreat tones using the two together into a delay
