Uglyface Question

[thumposaurus]

I built an uglyface useing Dan N's PCB layout, and despite the fact that I somehow managed to etch it backwards, it works fine except for the threshold knob. When it is turned all the way down the whole thing will cut out and the only way I've found to get it to come back on is to dis-conect the battery and then re-connect it.
So my question is will putting a small resistor across lugs 1 and 3(?) solve this by preventing the pot from reading 0 ohms?
Other than that small problem Uglyface is very cool.

Uh, sorry about that! I still look at PCB's the old fashioned way. Of course, I have etched a few PnP ready pcb's backwards myself. raddehC taerG? Damn!

Can't help with your pot problem. Looking at the schem you see there is never 0 ohms going to ground or to the power supply. If you found the spot where the pot has rotated too far, you could measure it and change the value of the resistor on the board (1K or 220K)? Still, that does not explain why the problem in the first place...

It was no big deal with the PCB I've etched pleanty of them backwards, the only big issues I ran into was I had to bend the legs on the chips so that they went into the sockets upside down.
As for the other thing I think it took care of itself, I was adjusting the height on the pots, and after I got everything tightend back down it went away so I guess maybe I had a wire shorting to ground at one point.
