Here is a bit of background story: It was 1982 and Fred was studying for his junior year finals at Northeastern. He lived in an old apartment building on the Fens...so close to Fenway Park he could open the window and hear Red Sox games. It was roasting hot outside and he had no air conditioner. The kitchen window opened onto a central courtyard, and that's where he liked to sit and study.
Right during finals week, a neighbor started playing her stereo at mind-blowing volume...and it stayed on. And stayed on. All night, all the next morning. He finally yelled out the window and she turned it down long enough to screech a few choice words back at him before turning the volume back up to explosion levels.
He headed to campus to get some peace and was struck with a wonderfully devious idea. Off to the engineering lab...where he built the circuit described below and put it to work until, in a fit of rage, the woman threw open her window and catapulted the whole stereo out to smash into smithereens in the courtyard!
Make a simple 9V battery powered transistor, capacitor, adjustable
resistor and inductor oscillator circuit.
The simple circuit is made with parts selected for FM-Band (88-107 MHz) tuning
capability and a one meter length of wire as an antenna for the RF trans-
mission. Sit in the kitchen and dangle the antenna out of the window.
Finally, a small screwdriver allows the "tuning" of the FM-Band Oscillator's
adjustable resistor, tune until there is silence as the "victim" attempts to tune in another station. Then turn the screwdriver again and knock out her new station. Eventually, stereo destruction....Coup De Gras !!!
