Brian Kaminski and his company Advanced Technologies have launched a Kickstarter campaign to raise funds to bring the fourth generation of his MyoWare biosensor to market. To help promote the campaign, Kaminski teamed up with Make Zine and published a tutorial to 3D print your own set of working Wolverine claws that will pop and retract based on the electrical signals from your brain.
