So when [GreatScott] rebuilt his recent DIY coil gun with discrete logic, mechanism for a small coil gun, and as such he chose an Arduino to. How to Make a Coilgun. When you hear the word coilgun, you might imagine a futuristic weapon that shoots electricity or coils, but these experimental devices. A coil-gun uses a magnetic field to accelerate a bullet up to projectile speed. Jason’s uses a bank of recycled rechargeable laptop batteries to.

For more information about the project, updates, and movies of the gun in action please visit the EM Coil gun webpage at www.

The doubler cascade is sometimes also referred to as the Greinacher multiplier. Completed circuit board and control coilghn. Mount the potentiometer, indicator LEDs, and coipgun to the control panel and then fasten it to the circuit board.

Capacitor energy storage bank wiring diagram. You can use any sort of light plastic or nylon tubing material that can be obtained at most hobby shops.

I have no idea what the transistor specs are, since there is no writing. Do Arduinos have flaws?

When the capacitor bank is charged to VDC, the amount of energy that will be switched to the accelerator coil is joules. Diode D9 is required to prevent the voltage from reversing.

Use a knife or saw with a fine blade to cut the glue at the coi,gun where the core halves are in contact if the E-cores are glued together. Dear Sir, In this circuit, Which type of Capacitor? Need to brush coilhun on your electronics principles? As well as the duty cycle? Its expensive to build and takes lots of experience in electrical work. Tips If the coil doesn’t stay, try something to retain it, like steel washers, or hot glue.

Insert the barrel the empty pen case into the solenoid, and glue it securely so that about an inch protrudes out of one end, and three inches out of the other, like this: Do not touch bare wires with your hands. The EM coil gun stays well below the legal velocity limits in Canada and the US, but because of the projectile weight, it should still be considered dangerous.

The Tools Soldering iron Hot glue gun Wire cutters Exacto knife Screw drivers depending on your disposable camera and your soldering iron, you could need Phillips or Flat The Procedure Build the transformer circuit using the schematic below, or follow these instructions on how to make the circuit if following the instructable guide, replace the film capacitor used with the one from your camera circuit.

Bend the metal and make a body out of that.

Use two plastic or cardboard discs glued to each end of the barrel on both sides of the coil to add support. Before extracting the flash circuit, take the batteries out of the camera and then waste the remaining charge in the capacitor by pressing the shutter and wasting the flash.

Open up the soldering gun, and remove everything from inside except the trigger button. The feedback voltage holds transistor Q1 on as the current flows through resistor R1 and capacitor C2. The velocities listed in Table 1 were measured with a commercial chronograph. This guide is only for coklgun technically advanced!! Not Helpful 0 Helpful 0.


Continue this procedure in increments of 50 volts until you reach VDC, marking each position of the potentiometer on the panel face with a pencil or marker as you go. When you’re done, take out the battery and touch any metal endings especially those of the coilgum with a screwdriver to release any charge. Every now and then a DIY project surfaces on the Internet that’s so cool we have to share it, especially those we should probably recommend you not try at home.

How to Make a Coilgun: 7 Steps (with Pictures) – wikiHow

On the other side of the bobbin, solder the end of a piece of 34 AWG magnet wire on post number 5 and then wind the secondary coil of turns in even layers. The completed grip with fire switch is shown in Figure You will need to experiment with the initial position of the projectile to achieve the highest velocities. The only time they mention microcontroller that I notice is when they are generalizing the discussion to the overall idea of micro vs discrete logic.

I bet you could do it with a single push-button and an analog delay line. Crack open the lamp at the seam, being careful not to break the glass tube, and remove the circuit board.
