What toy megaphones are really made of





I’ve heard of people turning these into effect boxes and for the longest time I wanted to see what those things had inside. My newest aquisition was promptly undressed and inappropriate pictures were taken. Oh My!!! Somewhere in that blob of cheap chinese goodness must be an A/D converter for the Mic and D/A that runs into a standard 386 amp. The effects must be some sort of a redementary DSP. However the board shows alot more interesting marks. OSC1 and OSC2 pins would suggest that an external oscillator can be connected. It would be interesting to hook this thing up to an oscilloscope and determine what wave alterations are being done to the signal. My current bending project is going well, so possibly Saturday this megaphone will get explored further.
