40kHz Voltage to Frequency Converter - This circuit was
designed to frequency modulate a 40KHz carrier, using human
voice frequencies. A common flip/flop is used at the core of
the circuit.

Air Transparency Monitor, Xenon Flash Receiver - I designed
this circuit many years ago to monitor the quality of a mile
long column of air for future optical communications
experiments. The transmitter system (circuit 72 below) uses a
powerful xenon flash in conjunction with a large 12 inch fresnel
lens at the transmitter end and a matching 12 inch lens with a
PIN photo diode at the receiver. The receiver system was
connected to a weather station and a computer to collect the
changes in intensity of the light flashes under different
weather conditions. It has the potential for a 30+ mile range. I
have also used this system to conduct cloud bounce experiments.
