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...
wireless FM bug
This project is a miniature, VHF FM (wideband) Wireless Microphone transmitter of the type that are commonly referred to as BUG's. Note that "BUGS" are illegal but "Wide-Band Frequency Modulation Wireless Microphones" (WBFMWMs) are not, as so many people have...
Video/Audio Wireless Transmitter
In this fast-paced world, there is little time for inconveniences and a greater need for portability and adaptability. The idea for an Audio/Video transmitter stems from this need. There may have been times when you’ve wanted to hook up your...
A Low Power Wireless Audio Power Amplifier circuit
This low-cost project enables audio reproduction from a television without disturbing others. It eliminates the need for wired connections between the TV and loudspeakers. Instead, it utilizes invisible infrared light to transmit audio signals from the TV to the loudspeakers....
Wireless remote control switch circuit 5
The wireless remote control transmitter circuit consists of control buttons S1 to S16, resistors R1 to R3, a capacitor C1, a regulator diode VS, a crystal oscillator BC1, and DTMF encoder integrated circuits IC1 and IC2. The circuit components are...
Wireless Coupler Terminal Interface
The purpose of the terminal interface is to allow my computer to communicate with Minimum Mass Wireless Coupler equipped devices using a terminal emulator program. Consequently, the Base Unit is basically an RS-232 interface and Minimum Mass Wireless Coupler. The...
Battery state of charge indicator circuit
During the charging process, the green light-emitting diode (LED) VLi indicates that the battery is sufficiently charged, while the red light-emitting diode (LED) VLz illuminates when the battery is low.
The circuit involves two light-emitting diodes (LEDs) serving as indicators for...
the design of the intellectual wireless signal transducer of ARM
The intellectual wireless signal transducer is designed for major transducer applications and typical sensor output signal designs. It is essential to first analyze the outgoing signals from the transducer. Typically, the output of the transducer is a standard electric current...
Wireless two-tone electronic doorbell circuit diagram
The transmitter circuit is activated by pressing the SB button. Components D1, D2, R2, R3, and C4 form a low-frequency oscillator that controls an audio oscillator made up of D3, D4, D5, and D6, allowing them to operate alternately. The...
