If you are eager to get fit but can't find the time or motivation – hack any console in this (possibly regrettable) way for fast results!

Cykill has been said to be America's BEST CHANCE at tackling child obesity.

The only way the gaming console will power on, is if you pedal the bike. Fail to pedal fast enough and Cykill will kill the power to your console. ☢ Possibilities of hard drive corruption ☢ Which should be enough motivation to keep you pedaling. (But don't worry, if you are concerned about wrecking your console's hard drive you can do the exact same hack to the tv/monitor instead)

It is a super super super super easy hack! Anyone can do it! All the work was in the code and that is already written for you ;)

Step 1: What You Need

Cheap Exercise Bike – I got this one for only 130$.
Arduino x1
Potentiometer x2
Knobs x2
Power Switch Tail x1
Toggle Switch x2
Neo Pixel LED Ring x1
Neo Pixel LED Bar x2
Laser Cutter & Acrylic (Optional. I used this acrylic for easy etching.)
Very Very Strong Super Glue
Typical Stuff: Wires, Solder, Resistors, Etc

Step 2: Intercept Signal From Bike Wheel

With most cheap exercise bikes you will find two wires traveling from the front bike wheel into the interface. We need to intercept those wires. So cut them! Then connect them to your circuit. In the photo you will see I just used simple jumper cables.

Step 3: Remove Existing Interface

Just tear it off. We don't need it. All we need are those two wires.

Step 4: Create Your Interface

The Interface includes:

Toggle button for Arduino on/off.
Toggle button for workout start/finish.
Potentiometer knob and LED bar for intensity.
Potentiometer knob and LED bar for duration.
LED ring to monitor speed.

My laser cut files are attached.

Even cardboard will work if you want something quick and scrappy.

Step 5: Build the Circuit

Neo Pixel LED Ring:

Neo Pixel LED Ring, Data __ ARDUINO PIN 2

Neo Pixel LED Ring, Gnd __ ARDUINO GROUND

Intensity:

Neo Pixel LED Bar, Data __ ARDUINO PIN 9

Neo Pixel LED Bar, Gnd __ ARDUINO GROUND

Intensity Potentiometer Signal __ ARDUINO PIN A0

Intensity Potentiometer Power __ ARDUINO POWER +5V

Intensity Potentiometer Gnd __ ARDUINO POWER GROUND

Duration:

Neo Pixel LED Bar, Data __ ARDUINO PIN 10

Neo Pixel LED Bar, Gnd __ ARDUINO GROUND

Duration Potentiometer Signal __ ARDUINO PIN A1

Duration Potentiometer Power __ ARDUINO POWER +5V

Duration Potentiometer Gnd __ ARDUINO POWER GROUND

Power Switch Tail:

Power Switch Tail Pin 3 __ ARDUINO PIN 13

Power Switch Tail Pin 2 __ ARDUINO GROUND

Toggle Switch Start/Finish Workout:

Toggle Lead A __ ARDUINO PIN 8

Toggle Lead B __ ARDUINO GROUND

Bike Pins:

Bike Pin 1 __ ARDUINO POWER +5V

Bike Pin 2 __ ARDUINO PIN A2 (add resistor shown in diagram)

Toggle Switch On/Off Arduino:

Splice the ground connection of the Arduino power adapter, and connect ground to both leads on this toggle switch. (Alternatively, you can just always leave the Aduino powered on if you want to skip this)
