    I have purchased a LOL Rollover Toy and wanted to modify it so that it doesn't shut off after the 10-15 seconds of laughing. I have disconnected the electric motors from the board but am not sure how to change it to stay on laughing as long as the power switch is on?

    Probably a software timer - not alot you can do with that. Youd be better retriggering it - maybe stuck a relay on the power connection and a circuit to detect power off

    Just guessing at things...

    I have been doing some research trying to figure out what these things do and how they might relate to a timer/switch. Am I guessing in the right ballpark about the 100uF 10v Capacitor might be what is doing the timing and cutoff of the power?
