“In addition to those items mentioned above, it would be a good idea to have some sort of screwdriver set that includes: #0 – #3 phillips bit, 1/16″ – 5/16 flat blade wire cutters, and wire strippers. A good substitute for cutter/strippers is…”

LucidScience – Gallery Project : ROCK DISAGGREGATOR – Page 1 of 18


This experimental rock disaggregator is powered by a pole pig transformer connected in reverse to charge a bank of five 50KV capacitors up to 500KV. The resulting high energy discharge is sent into an explosion containment vessel.

spy transmitter made from radio parts

Radio frequency projects can seem more difficult than most electronics projects because most of the time you cannot build them on a solderless breadboard and there may be parts used that are not easy to source such as coils and adjustable capacitors. This project is focused towards those who have not yet attempted to build any kind of RF project, and it is laid out in such a way as to make it easy to explore the basic principles of RF circuitry and ensure a successful final product.

This simple 2 transistor audio transmitter will send the sounds picked up in a room to any FM radio tuned to the same frequency as the transmitter, somewhere between 80 and 100 Megahertz. The expected range will be at least 100 feet and could be substantially longer depending on the parts used and the quality of your final product.

This circuit is based on one that has been around since the 1960s and published thousands of times, so it is tried, tested and guaranteed to work if you follow the instructions. Performance is “OK”, but since this is the one of the most basic transmitter circuits possible, don’t expect high quality or rock solid performance.

You can salvage most of the parts needed from an old radio.
