555 AM radio

I have earlier written about 555 timer design contest. The contest is over and winning circuits have been found. Here is one very interesting contest entry (got second place in Minimalist category): AM radio receiver built around 555 timer IC.

Look at the following video that presents the circuit.

    to talk. Plus the water serves as a “cough button” if needed.
