100j Coilgun

This was my first attempt at a coilgun.  It was my first project I did with my new high capacity capacitors.  It could only punch a finishing-nail through paper, but still cool nevertheless.

Variable Freq Transformer Driver

Transformers come in all shapes and sizes, and require different frequencies to run at their highest efficiency.  This is a simple circuit that allows me to drive any transformer with a 5-50v (peak to peak) square wave, with a max current of about 10A.

1360v Cascade Multiplier

This was my trial at getting a variable powersupply for my capacitor bank.  It used a household AC line, and rectified to up to 1360v in 170v tapped increments.  While I got the voltages I wanted to, It unfortunately didn’t have a high enough current capacity to charge the capacitors.

External USB HDD Tower

While this isn’t the prettiest external harddrive, it is functional.  I needed additional storage for my computer, and I didn’t want to shell out large sums of money for external harddrives (plus it gave me something to build).  It simply takes a PC powersupply, 3 internal harddrives, IDE to USB adaptors and a usb hub, and has a max storage of 900gb (this was before they had 1tb harddrives).

Neon Sign Transformer

Early junior year of college, I had this toy given to me to play with.  I had always seen them online in videos and HV projects, but I had never actually gotten to use one.  With it, I’ve made a Jacobs ladder, fried a CD, and melted hotglue (don’t ask).  If anyone has a request for something being hit with 15,000v of electricity, let me know.

HV Transformer / Flyback

These were probably my first high voltage circuits.  Before I had the variable freq. transformer driver, I needed to make a simpler 555 circuit to drive these.  These had enough voltage to make and sustain an arc of about a half an inch.
