So while at the shop this saturday Krux got the ShopBot moving and doing at last! It seems like the frame is square and all the parts are in their correct orientation because the logo turned out great. Good job!
Two minutes of the most annoying sound I’ve ever made. =P I may stick with this circuit, however if possible I’d like to find another schematic that produces a different tone… in a deeper pitch. It would also be very nice if when my hands weren’t near the photo resistors the sound would just stop. Even I have a threshold for irritating.
