Wireless Auto Tachometer
Anyone performing their own automobile tune-ups knows how important it is to know your engine's speed. With this tachometer, you can measure your engine's speed without any connections or annoying timing lights.
The described tachometer is a non-invasive device designed for...
magnetic gun
When optimally tuned, it will propel a small slug about 1.5 meters high or 2.5 meters horizontally.
The described mechanism appears to be a projectile propulsion system capable of launching a small slug, likely a lightweight object, to specific heights and...
Wireless Telephone Bug
Wireless Telephone Bug. This project enables monitoring of a phone line as soon as the phone is off-hook. A regular FM broadcast band radio can be utilized for this purpose.
The Wireless Telephone Bug is a circuit designed to allow users...
Wireless-video-camera-link
This high-performance video camera link transmits signals from a video camera to a VCR or from a VCR to televisions throughout a home. The initial stage of the RF chain is a crystal-controlled oscillator, Q1, operating at a frequency range...
Homemade wireless remote control circuit diagram
The homemade wireless remote control circuit diagram illustrates a motor remote control transmitter circuit. The circuit utilizes a 555 timer along with resistors R1, R2, RP1, diodes VD1, VD2, and capacitor C1 to create a variable duty cycle astable oscillator....
Wireless alarm FM transmitter module
There are many alarm systems available, but building a custom one may be appealing. This project can be assembled using affordable components that are easily accessible. The alarm transmitter module features a delayed trigger and an automatic turn-off function, operating...
Low frequency oscillator-flasher
Electrolytic capacitors are not required to generate a 1 cps frequency. When the silicon-controlled switch (SCS) is triggered, the 0.2 µF commutating capacitor deactivates the other capacitor and charges its gate capacitor to a negative potential. The gate capacitor charges...
