1stprototype

We decided to give a try to use AGIC Silver Ink Master as a conductor to make a pressure sensor. So we paint the square papers with using silver ink for the conductivity. We use sponge as nonconductive material to give the sense of pressure. What we realize is that once we start to press the sponge, led lights up. The only thing changes the led’s brightness is that how we squeeze the battery.

Ps: AGIC Silver Ink works perfectly!!!

2nd prototype

After realizing the brightness is changing depending on how we squeeze the battery.

We decided the use this pcb battery holder(which I found on Maker Faire) and i stick the battery really tight. In that, this time we don’t have to squeeze the battery to have a more bright LED.
