Drive A Plasma Ball With An ATV Ignition Coil And A 555

[Discrete Electronics Guy] sends in his short tutorial on building a high voltage power supply from simple things.

The circuit is a classic, but we love the resourcefulness shown. The ignition coil comes from a three wheeler, the primary power supply is a ATX supply from a computer and the oscillator is powered by a 9V battery. We do wonder whose vehicle stopped working though.

He gives a great explanation of how the circuit works and was constructed and then moves on to build his own Plasma bulb. Despite expecting something more complicated the end result was achieved by putting a lightbulb on a stick. Fantastic. The circuitry was nearly packaged into a takeaway food container and the entire construction was called complete.

All in all it shows what someone can accomplish if they’re resourceful and understand the basics. However, it’s probably that you don’t electroBoom yourself to death if you can avoid it.

High Voltage Plasma Lamp Is Also Tasteful Steampunk

Instructables user [Admiral Aaron Ravensdale] just finished a high voltage plasma bulb build that makes creative use of off-the-shelf parts. As a self-described steampunk, [Adm. Ravensdale] also earned some cred by included working gears in his build.

The heart of the build is a “flicker flame” candle light bulb. These light bulbs have two flame-shaped plates inside the bulb to act as electrodes. Instead of the Argon that normally fills an incandescent light bulb, the candle bulb is filled with Neon. When excited, Argon gives off a rather unnatural purple glow – not very convincing for a simulated candle and certainly not steampunk. The Neon in the flickering candle bulb gives off a brilliant orange, perfect for simulating a flame and will surely impress the duchess during afternoon tea.

After the right plasma bulb was found, [The Admiral] scavenged the rest of the high voltage electronics from disposable cameras. Attaching three electrodes to a brass gear, the entire mechanism was made to spin using parts from an old clock and a CD drive motor. We’re always impressed with the scavenging abilities of steampunkers – we’d still be waiting for our gears to arrive if we attempted this. Check out the video of this really cool and very inexpensive plasma bulb after the break.
