Opps. I knew the pots and the UNO was on the underside, but I didn't think about just stacking it over the tracks.dazq wrote:I know its single sided but can you not put the uno on the back of the board to reduce its size? Else thats a lot of wasted copper board to etch...
I also forgot about soldering it on the under. It would take some tricky soldering but I think it is possible, either that or flip the UNO and put it on top with a pot in each corner on the underside for legs.
I'll have a play with it, and I might be able to get it to a 100 x 100 broad now.
The 555 is the other board I'm looking at, but I don't have an actual Speedy to check if it's going to be ok.
I'm not that keen on the oscillator on the other one because of the problems I had with it so I'm looking into alternatives. You can buy a $1.20 ready made square wave with adj duty and freq osc, but you need a multimeter to set it up before you turn it on, and that doesn't make it PnP.
