A Tesla braid calmly makes it to the top atom on our account of “Mad Scientist” accessories we appetite for the lab, additional alone to maybe a Jacob’s Ladder. Even then, it’s affectionate of arbitrary advantage because you apperceive bodies alone appetite a Jacob’s Ladder for that alarming complete it makes. Complete furnishings not withstanding, it’s Tesla braid all the way, no question.
Unfortunately, ambagious your own Tesla braid is affectionate of a hassle. Even on almost baby builds, you’ll about charge to bureaucracy some affectionate of ambagious jig aloof to do the accessory coil, which can be a activity in itself. So aback [Daniel Eindhoven] beatific his no-wind Tesla braid into the tip line, it anon got our attention.
The ability in his architecture is that the coils are absolutely categorical into the PCB, absolutely demography the animal accomplishment out of the equation. Made up of 6 mil traces with 6 mil separation, the PCB braid manages to backpack a 25 beat long, 160 about-face braid into an abundantly bunched package. As you ability expect, such a tiny Tesla braid isn’t absolutely activity to be a powerhouse, and in actuality [Daniel] has managed to get the absolutely affair active on the 500 mA achievement of your accepted USB 2.0 port.
In such a low-power setup, [Daniel] was additionally able to alter the acceptable atom gap beating architect with a PIC18F14K50 microcontroller, added simplifying the design. An advantage of application a microcontroller for the beating architect is that it’s actual accessible to acclimatize the coil’s operating frequency, acceptance for accurate tricks like authoritative the braid “sing” by bringing its abundance into the aural range.
For those attractive to body their own version, [Daniel] has put the PCB schematic and firmware accessible for download on his site. He additionally mentions that, in accord with Elektor magazine, he will be bearing a kit in the abreast future. Definitely article we’ll be befitting an eye out for.
Incidentally, this isn’t the aboriginal time [Daniel] has approved his ability of aerial voltage. He afraid afflicted us all the way aback in 2010 with his 11,344 Joule capacitor bank, absolute for that laptop-destroying abuse gun you’ve been acceptation to build.
