I was at Fablab Amsterdam where a milling machine for PCB's was:

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:

Step 2 is to add a resistor and a light sensor to change the sound:
