6: First test!
Insert the batteryholder. The side with the spring should go in the AAA- hole.
Don't solder yet!
Now insert the battery.
Test the synth by holding both ends of the pcb with your fingers.
You should hear a BEEP sound!
If not, recheck your soldering and the steps above. Is the battery holder orientated correctly?
If it works, you are ready to solder the battery holder in place. Do so.
Snip off the pins. This might be hard as the are thick, so be careful!
8: Pencil
Use the small tiewrap to attach the pencil synth to the pencil .
Slip it in between the transistor and the large capacitor:
9: Copper tape
Take one piece of the copper tape. Peel off the start of the paper (but not entirely!)
Be careful with this tape, as it is quite fragile.
Stick one end on the silver end near the speaker. Slowly wrap it towards the thumb-tac.
Carefully roll it around the metal of the thumb-tac.
Use a tweezer to clamp it down and make it stick.
Solder the tape into place to secure the tape.
