Make a homemade vacuum tube tesla coil using these vintage diy plans from the 1940’s.
Other types of tesla coils, calling for a high tension transformer and spark plug gap for excitation, were undoubtedly interesting and instructive, but this vacuum tube design shown above will prove much less expensive to construct and yet will provide plenty [...]
SQUARE WOUND TESLA COIL PLANS, uses transistors and a 3 kv neon sign transformer. Highly detailed with diagrams and complete written instructions. Includes plans for rotary spark gap.
Nikola Tesla, considered by some to be the greatest inventor of the electronic age, is today best remembered for his fascinating power transmission experiments using his famous tesla [...]
This SOLID STATE TESLA COIL produces wireless transmission of radio frequency energy using a modified fly-back transformer from an old television. Detailed diagrams and complete written instructions included.
This DIY project shows how to construct a high frequency, high voltage device capable of causing a fluorescent lamp to light without wires and produce the corona effect [...]
Get out of speeding tickets the easy way with this handy radar jammer electronic shield. Be cloaked like a ghost as you whiz down the freeway past all the cops and cameras.
The dipole antennas, which reflect radar, consist of four nickle rods with 32 dipoles bound to them. Each dipole antenna should be cut to [...]
This flyback tesla coil uses a high voltage flyback transformer salvaged from an old TV, or ordered from Fair Radio Sales. Look for the biggest, most intimidating transformer you can find. Old tube TV’s are a good place to look. The transformer should not have a rectifier built in.
