How To Make A Tesla Coil Gun At Home
A Manus Held Tesla Whorl Bombardment Powered 'Plasma Gun'
The design for this Tesla Coil is based on the larger bombardment powered DIY Tesla Coil projection but with the aim of getting a much smaller and portable device. A Power Pulse Modulator circuit is used to bulldoze 2 small high voltage ignition coils wired together in an 'anti-parralel' configuration. The output is rectified and used to accuse the tank capacitor of a small spark gap Tesla Coil.

The device is packed into the casing of cheapo cordless drill from a DIY store. This drill used an 18V bombardment and comes with a charger which made it ideal for the project. The ignition coil driver circuit used takes a direct 12V – 30V input which is connected using the original switch from the drill.
This video clip shows the plasma gun causing a nearby low-cal seedling to light up as if it were a plasma globe.
The high frequency, loftier voltage from the plasma gun causes the Argon gas in the light bulb to become ionized. This creates streamers that are attracted to the fingers belongings it.
The device draws about 6 amps from a well charged 12 Five battery which makes the total power consumption to around 72 watts. Unfortunately this low power ways the plasma arcs will exist limited in size, simply since it is mitt held that's probably a adept thing. The typical length of the output arcs is betwixt v and 7cm
Such a small Tesla Coil inherently has quite a high resonant frequency which in this case is about 500 kHz. This frequency is also high to feel as electric daze just when existence zapped you tin experience the low frequency component of the spark gap firing rate.

The main driving circuit is a type of pulse width modulation circuit with protection confronting high voltage spikes. Information technology is adapted to get the maximum output from the two ignition coils.
The 2 ignition coils were stripped of the casing in order to reduce the overall size and let access to the internal wiring. The inputs are wired in an anti-parallel system to aid continue the charging voltage high when under load.
The HV outputs of the spark coils are continued to a rectifier (D1) made from four HV diodes potted in epoxy resin. Connected to this is a modest smoothing capacitor (C1) which helps to reduce the ripple in the HV DC output. The tank capacitor (C2) is charged from the HV DC supply via 2 RF chokes (inductors L1 & L2) which serve to preclude the RF oscillations of the TC primary excursion from interfering with the rest of the circuit.
The previous battery powered tesla gyre design needed to be well connected to a good RF ground such as a metal rod in the globe. Without this the output would be limited and the commuter excursion would be prone to failure.
With this mini tesla coil the RF ground connection is fabricated past connecting it to a copper pad on the handle.
The body of the person holding the device is used equally the RF ground and the large area of copper ensures the energy is spread out to prevent RF burns.
In almost Tesla Coils this would non be rubber at all only this device is very low power and so in that location is little risk of electric shock. The RF its self probably isn't besides salubrious though!
The TC part (Tesla Whorl) uses the common single static spark gap and apartment primary pattern for simplicity and size. The chief coil is closely wound around the base of the secondary with several layers of insulation tape preventing flashover.
The topload sphere is made from a metallic describe handle which has been drilled to permit gas to be ejected from the end. A pipe from this sphere runs downwardly the within of the secondary and to the back of the handle where it tin exist connected to a gas supply.
Using noble gasses such as Argon or Neon volition cause the output arcs to be forced along the flow of gas. This allows the plasma to exist directed in a straight line from the tip of the plasma gun. Information technology is also possible to use butane gas which makes this thing into some kind of flamethrower – plasma gun hybrid. The electricity is conducted forth the flame from its tip. You can meet photos of this effect on our plasma page.
Autonomously from making cool arcs of plasma, this device even transmits wireless electrical ability. Information technology can lite bulbs and fluorescent lights but from being nearby.
The interference created by this wireless free energy can cause all sorts of electronic devices to switch on and off or offset behaving erratically. This is considering the energy is causing tiny currents to be induced in the tracks and wires in the devices. If a simple circuit had a matching resonant frequency to that of the plasma gun, it would be possible to collect the wireless energy from a greater altitude.
At that place are several improvements that could be made on this blueprint which could result in a greater power throughput and therefore bigger arcs.
The spark gap is just a single gap which has been seal inside a plastic example for rubber and size. This sort of switching volition have poor performance due to quenching difficulties and oxide buildup. A solid country version would be better only it would likely be larger and considerably more expensive.
A larger topload would allow for larger breakouts, but it would also need more than master capacitance. The secondary curl is also rather long relative to its width. Ideally this would exist shorter and wider.
In conclusion this was a fun projection and we hope you lot find this data useful and interesting.
