Interesting projects of the past

I've done a variety of interesting things over the years. The following list is but a small number of them (i.e. the ones for which I had easily html'd descriptions or neat photos):

• Radar signal analyzer EC105. (photo)200 MHz instantaneous bandwidth with 25 kHz resolution using multi channel compressive receiver for 100% intercept. Receiver front end tunes to 18 Ghz using a phase locked YIG oscillator. Each compressive receiver channel (photo) processed a 50 Mhz wide section using a SAW dispersive delay line (SAC) with a common digitally synthesized chirped LO adjusted to current temperature.
• Roger, an autonomous robot (photo) with sonar obstacle detection and dead reckoning position keeping.
• A 40 foot high man made tornado with 70+ mph winds. More info at Reel EFX's home page.
• Artificial Lightning, created by exploding wires with high voltage, high current pulses.
• A picture of some sparks from my 500 kV Van de Graaf generator
• Photos from a small Tesla Coil in operation.
• Experimental Web based photo portfolio (uses frames)
• The pneumatic potato cannon
