While researching solid state Tesla coils we stumbled across this old project. As you have probably guessed from the pictures, this coil is meant to actually play music. Knowing how to add eye catching flare, the coiler uses a Plexiglas frame turned light pipe; only to be complimented by an audio amplifier complete with graphic equalizer. There is a video of the coil in action on YouTube. We have covered singing tesla coils in the past. Other twists on the classics include the tesla coil guitar amp and a hand held plasm gun.

Automated Paintball Sentry
Reader, [Ben Godding], sends in the video for his senior design team’s automated paintball sentry. The frame is made of plasma cut aluminum. The paintball gun uses a custom hopper mounted remotely from the gun body.

VR Game Gun
Many of you have probably experimented with alternative gaming interfaces. Here’s a well done little hack where they created a gun with a display mounted on it, for video gaming. At a glance you can probably figure out exactly what they’ve done. They’ve attached a gyration mouse to the gun for tracking and gutted a keyboard for the buttons. We have to give them some credit, they seem to have packaged it all nicely. Since it’s a standard mouse and keyboard, it just plugs in and works with any game. As you can see in their version, the screen…

Repair a Malfunctioning LCD

Bolt-action coil gun
TechEBlog has posted a few pictures of a student constructed coil gun. It’s bolt-action and includes a six round magazine. The gun only has a single stage to accelerate the projectile. While not as impressive as the portable coil pistol, it’s still more fun than most shop projects we’ve seen. You can find a video of the device below.

Portable coil pistol
[Daniel] had to have runaway in his mind when he built this coil gun. It’s hand held, holds 14 42 gram rounds and can propel them at speeds of 110km/h. Of course when it is battery powered, you have a 90 second warm up time between shots. It can also be used while plugged into a wall socket, which reduces the charge time to roughly 3 seconds. Great job [Daniel].
