James Grebey (known online as The Hacksmith) has built a real-life Captain America Shield and it’s too awesome!
What would you do for a fully functional Captain America shield replica that is able to automatically return to the wearer’s arm? Pretty much anything, I’m sure. Grebey has created this awesome weapon/device/toy/shield using electromagnets. The electromagnets are capable of lifting over 3,000 pounds, allowing him to toss really heavy objects, and break through concrete bricks. Now all you need is a super serum to give you super strength.
We made this awesome electromagnet arm bracer for the Replica Captain America shield, just in time for Captain America: Civil War. It uses a set of lithium-polymer batteries from Hobby King (http://fave.co/1VycT2u) running in series at 72V. This produces 720kg of magnetic force at each electromagnet. That’s over 3000lbs of magnetic lifting force together!
The electromagnets are available on Amazon (http://fave.co/1qinRvO), and are rated for 12V, which produces ~120kg (1200N) of lifting force. We’re running them at a much higher voltage for short periods of time to create awesome power. They will overheat if you use them for over a minute at this power level!
