Toorcamp: The Tesla Gun

We discussed [Rob]‘s Tesla Gun in the past. At that time, the build looked very impressive, but had not been fired yet. Fortunately, [Rob] got the device working and brought it to Toorcamp. He took the gun out every night and demoed the handheld Tesla Coil by having volunteers catch the streamers with a knife.

The gun uses a cordless drill battery for power, and a flyback transformer to generate the ~20,000 volts needed to drive the coil. The power electronics module was designed to be easy to replace, and [Rob] had extras at Toorcamp in case he burnt one up. [Rob]‘s build log is very detailed, and definitely worth reading through. It explains how he cast the enclosure out of aluminium, built a custom porcelain high voltage switch, and designed the power electronics.

While this build should probably get a “do not try this at home” label, he definitely created something unique. We’re looking forward to when [Rob] shows the gun off next.

    Came here hoping to see a working version of a Warehouse Agent weapon by the same name. Not disappointed. :)
    It is a little larger than the version on the show, but still awesome.

    isn’t a terroid an awful top load to choose when directing the energy? i’ve seen one person who used a full size Tesla coil that directed it’s arcs through an acrylic tube with argon flowing through it.

    Walk down the street with this and NOBODY will mess with you. Except the cops – and they’ll shoot first and ask questions later.

    And now makes for the possibility of developing a portable light-saber prototype.
