WEEK #6 ETCHING

During the class we made step for step a 555 led blinker circuit in Eagle.
Then we printed the circuit on copper and started etching.

WEEK #7 ETCHING

Soldering our own 555 led blinker circuit.
Step 1 is to connect all the elements to the circuit to get noise out of the speakers when you touch the touch-plates:
