Coil Gun

⚡ This is my best guess at a practical implementation of a Coil Gun, which launches metal projectiles using the magnetic fields generated by an inductive coil, which has a diode clamp to reduce back EMF which would slow down the projectile.  The 10mF cap represents the capacitor bank, and the inductor is the coil itself.  The circuitry on the right is a one-shot timer and additional CMOS buffer to eliminate switch bounce. ⚡

⚡HOW TO OPERATE: ⚡

1. Switch SPDT to charge cap. Red LED indicates cap is charged and dangerous. 

2. Switch it back.  Green LED indicates coil is in armed position.

3. Press pushbutton to fire.

4. Enjoy!

Note: this circuit has voltage controlled voltage sources in order to get around limitations in the software, and these are not necessary.  High impedance voltage dividers can be used instead, and the RC circuits are only so EC can find solutions.

@WTFCircuit thank you! You were right, I was going off the top of my head with this design and mislabeled this.

But the transistor blew on the third firing.
