it's about the size of a pda with a2 inch lcd screen has 3 or 4 tune and the A B C's........now it's a monster.put a osc in it to make it loop. pitch up,down speed up,down found 2 different distortions pulled the lcd andflipped it 180 on it's contacts now it's bonkers,  mod to the osc with a 6 way switch to select fromdifferent caps to change the timing on my 555 around when needed only acouple more thing left #1 is to build a ring modulator and  to get that damn photo res to work as a pot for the osc . IDEAS? had to find a box for my new friend i figured the all this crap would not fit into that little case
