E textile and wearables I

First experiment

I create a simple circuit to be familiar with the position of the LED, the resistor and the battery.

The led needs te be on the correct orientation. Anode (+) to cathode (-) from VCC to GRD (Ground).

D i g i t a l

Only two possibilities. ON/OFF

Contact sensor –> make the connection between two part to close the loop and create a circuit.

The circuit is placed on a breadboard to have an overview of the fonctionality.

Project

I used the mold made during the assignment Bioplastic and Natural dying.

With the mold, I traced the lines on a copper foil and cut with scissors (the vinyl machine would have been more appropriate for this)

I add 3 LEDs and try to put them in series.

I cut the copper to separate in 3 parts for each led to not create a gap or a short circuit.

I had to solder some part because of the glue on the copper paper.

Because the LEDs are in series and each need 3V I have to find a way to connect a 9V battery.

NB :The LEDs placed in parallel would have dispatched the Volt and it would have been possible to connect a smaller battery.

Connecting the 9V battery to the stripes respecting the + and – the LEDs turn on.

- 3ml Glycerin

- 12G gelatin

- 60ml water

- 3 drops of acrylic gold.

I let it dry few minute and removed the mold.

before to connect the battery to the circuit, the bioplastic need to dry to not create a short circuit because of the water in it.

after 3 days, I tested the circuit :
