Here’s a rather fascinating hack that involves using large capacitors in series to power the tesla coil. The result? Indeed rather amazing, watch video below to enjoy sparks!
I need a 3 Turn coil (110mm) with resonant freq fo=235,6kHz, calculations tell me I need a 240nf capacitor bank. Usually a capacitor bank consist of a series/parallel circuit combination and requires extra wire length and space. This will change the inductance of the circuit and thus change its res
For those of you fascinated with electronics and big sparks, you might want to consider making yourself (or your friends) one of these vacuum tube tesla coils. Not only are they great conversation-starters, they can be great for parties at your home, just make sure to put some protection around it so people don’t get zapped!
Can’t find a neon sign transformer? Don’t want to face the complexity of building a Solid State Tesla Coil just yet but want big sparks? If so, then a Vacuum Tube Tesla Coil might just be the right thing for you. You can build this rel
I’ve always been fascinated with tesla coils and the amount of physically-viewable electricity jolt they can send across the thin air. We’ve had a post before on how to make your own tesla coil but here’s another great tutorial showing you how to build one yourself, all in the safety (arr…perhaps the opposite) of your home without endangering others.
The author mentioned that all this can be conjured up for rather cheap
Here’s a rather interesting DIY motion-activated mini tesla coil. It seems to work pretty well, this could be one of the best Halloween tricks you could implement to your trick-or-treaters. (via make)

Holy crap, this is some tight tesla coil action!
The 6 inch coil has performed better than expected with sparks reaching 8 feet (0.5 million volts). The photo above shows 7 foot sparks to the closest point of the ladder. This is with a large topload and a tank capacitance of 92 nF (0.092 uF) at a power in excess of 5 kVA. A lot of smoke comes from my spark gap at runs of over 5-10 seconds at the highest powers. I suspect it is
