![]() | DIY Electromagnetic (HERF) Gun Project
This DIYer built his own Microwave HERF (high-energy radio frequency) gun by using parts from an old microwave oven. The electromagnetic gun works just like a normal microwave with a high energy source triggering a magnetron which produces... |
![]() | How to: Controlled Levitation using Magnets & Microcontrollers
Here are four superb examples of combining electricity and magnetism to create wirelessly powered, levitating objects. Typically using two copper coils for induction, the some methods in the tutorials below transfer electricity through thin air. ... |
![]() | Wi-Fi Enabled Coil Gun with iPhone App
We've covered loads of airsoft, nerf, and gun projects, and here's another superb pr0ject to add to our collection. It's a coil gun placed on a turret which is triggered via Wi-Fi. Additionally, it uses remote targeting and shooting through... |
![]() | Electromagnetic Firepower with a DIY Coilgun
Electromagnetism packs quite a punch. Coil guns, like the one pictured above, use electromagnetic coils to push a ferromagnetic projectile rapidly through a barrel. The electromagnetic current is usually drawn from a battery and controlled with... |
