Musical Table

Step 4 Making a soft swtich with conductive tape(one half of the swtich)

Make seven different combinations of switches that play a musical phrase when connected to a base. Each switch has four bars made of conductive tape. The first bar connects to the power and the rest connect to three pins on a base.

 

1. Cut seven 1 3/4” x  3” trapezoids from foam board.

2. Cut seven  1 1/2” x 1 3/4 squares from foam board.

3. Make combinations.

            With 3 pins, you can create 8 different combinations of switches through differing shapes of conductive tape. On/Off indicates when pins are connected to power.

Combination1-On, Off, Off (Power, Pin 13, Pin12, Pin11)

Combination2-On, On, Off

Combination3-On, Off, On

Combination4-On, On, On

Combination5-Off, Off, On

Combination6-Off, On, Off

Combination7-Off, On, On

Combination8 –Off, Off, Off (this means nothing is connected to power. We will skip this one)

4. Here’s an illustration of the switches and the base pattern. You can use this as a template and cut  conductive tape in this shape.

5. Leave 1/4” on each side and attach conductive tape shape on one of the foam squares.

6. After the conductive shape is attached, glue the square switch to a foam trapezoid.

7. Apply hot glue a toy on a trapezoid.
