I quickly put together a few small Marx generators and a few small slayer exciter coils which were easy to build and worked amazingly well. This kit which I put together in an evening gave me a fascinating glimpse into the world of HV electronics. Soon after this encounter I bought my first tesla coil kit from Easternvoltageresearch. My interest in HV was rekindled several years ago when I encountered a plasma globe at the Pink Palace Musem in Memphis Tennessee. This marked the end of my HV experimentation for about 20+ years as I dealt with other of life’s challenges. I could never get the thing working again and didn’t have the means to go buy a new transistor. I could never pinpoint what happened and suspect it was either a short in the secondary which was rather randomly wound, or the transistor had failed.

Then something happened and the transistor or the coil failed and the neon light went out as quickly as it came on. I didn’t even own a soldering iron and used twisted connections for all the electrical joins! I powered the contraption from a 12V car battery that was lying around in the house and to my amazement it actually worked and wirelessly lit up a small neon bulb at some distance away. I got interested in High voltage projects when I was a kid after putting together a small home made Flyback coil with a melted candle wax core, a primary, feedback and secondary coils with wire that I obtained from an old transformer, and using one transistor and one resistor.
