Supplies

3D Printer (some sort of Box)

Speaker

CPB (Circuit Python Bluefruit)

Battery Pack for CPB

4 Alligator Clips

Super Glue

Drill

Wood Panel

Print Letter-Box

First, we have to find a Box, that fits our CPB and the speaker.

You could also connect the Speaker outside the Box, but inside looks cooler.

Step 1: Drill Holes for Speaker and Cables

I drilled 2 holes for the speaker. The one to get access to the on/off switch of the speaker and the other hole to get access to the speaker charging outlet.

In addition, I drilled holes so, that the sound of the speaker finds a way to get out of the box.

Step 2: Write Code, Connect, Set Parts

I'll put the Python code to the end of the instructable

I glued in all parts, but you could use any other method

2 alligator clips are connected to the box (AUDIO & GND)

2 alligator clips at A1 and A2, the other end will be connected to the aluminum fields

Step 3: Create Capacitive Touch Fields and Connect

I glued aluminum foil to the lid of the box. Then I connected alligator clips to the backside of the lid.

I made two touch fields. Every field plays an individual sound.

Step 4: Finish

Glue on the Lid, make sure all parts are in the right place.

Screw/glue the box to a wood panel.

Place the battery pack somewhere. (I used zipper so that changing batteries is made as simple as possible)
