Introduction: ElectroFried Electronic Shock Game

About: I'm Toon, I see myself as a maker/hacker. I'm founder of AppSaloon a small web company. I also founded the arduino-jam. I like: electronics, programming, woodworking, 3d printing, science, technology, metalwor…
The ElectroFried is a game with a shocking fun level.
ElectroFried is developed for the Global Game Jam 2011 in Antwerp in design center the winkelhaak.

The Team Jekkos/ Cinezaster decided to make a simple game based on colliding electrons.
With a nasty side effect, a electro shock.

As a input devised I hacked a old computer mouse to control the electron and bring it to the proton without colliding with the other free spinning electrons.

A transformator of a disposable  camera is used to generate high voltages on the input mouse.

5 leds are used to show witch level you are and show animations in between.

A arduino controls everything.

Step 1: The Controller

The controller is a old mouse. I removed almost everything inside and soldered my wires on the switches of the buttons.

On the arduino side there are pull-down resistors to keep the input level LOW when no switch is triggered.

Step 2: The Shocking Device

For the shocks I gutted a disposable camera and sourced the transformer out of it.
The transformer is a step up transformer.
I used a power NPN BD139 to generate some kind of alternating current through the transformer. After messing around with the components that came from the camera. I switched to a more software generated alternation.

I used the tone function of arduino to generate a 50000 Hrz signal, this delivers about 1000 Volts.

I used batteries to power because the frequencies could interfere with the arduino.

Step 3: 5 Leds

5 leds to animate, I used 5 digital outs to interface.

Step 4: Arduino Code

This is the arduino Code. It's serial connected over USB and talks to our JAVA game.
The zip file contains the java game.
