Have you ever dreamt of controlling the people around you? Family, friends, co-workers, even total strangers? Well now that power is yours thanks to the cutting edge of neuroscience and biotechnology, the Backyard Brains Human-Human Interface. With our electrophysiology setup, you will learn exciting neuroscience concepts first-hand as your brain sends an electrical impulse to your arm's muscles, telling them to move, and when your muscles move, this generates an even larger electrical signal. You'll take that electricity, then further amplify it and inject it into the nerves controlling another person's arm.
Warning: The power to control another person can be addictive. Backyard Brains is not responsible for any plans for world domination that arise as a result of our products.
Your new Human-Human Interface is ready with all of the materials you'll need to connect yourself with another person. It comes with an Arduino microcontroller (it's like a small, easily programmable computer), already programmed to facilitate your newfound dreams of power. Plugged into the Arduino is our Muscle Spikershield, which lets the Arduino understand the signals coming out of your body. With this, you can see the electricity in your muscles as they move, but more importantly, use them as a signal to turn on the stimulator.
The sensation of totally losing free will can be a little weird at first, so just relax.
You'll be hooked up to the all-important TENS stimulation device, which harmlessly delivers electricity to your arm's nerves. The other person, the Controller, will be using the electrical signals from their voluntary muscle movement as a signal to turn on the stimulator. When this happens, your nerves will interpret the electricity as a "contract" signal, and tell your arm to flex.
With all this, you're ready for fun and educational neuroscience experiments for students, kids, and adults.
