Battery-powered fence charger
The circuit is fundamentally an auto ignition coil paired with a set of points that perform a similar function. It employs a pulsing circuit constructed from a single CMOS NOR integrated circuit (U1) to open and close relay contacts, thereby...
Portable Nicad Charger
The portable charger is designed primarily for model enthusiasts to charge their NiCad batteries using a car battery outdoors. The circuit's supply voltage is regulated by IC1. When connected to the car battery, LED D2 illuminates only if the NiCad...
project key
This battery-powered monitor is designed to provide an audible indication of keying for transceivers that lack a CW sidetone. Its sensor wire is wrapped around the transceiver's coax, eliminating the need for a direct connection. While primarily intended for Morse...
Low-Power Amplifier with digital volume control
An amplifier with digital volume control can be designed predictably due to the simplicity of the circuit, which utilizes a single chip, the TDA8551. This series of mini amplifiers with digital volume control operates as a BTL (Bridge-Tied Load) amplifier...
connect 4000
The objective of this project was to investigate the wireless linkage of objects, locations, and individuals. Initial discussions revolved around the intended use of the project—whether for private or public purposes—and the number of participants involved. Considerations included the choice...
Battery Powered Night Lamp circuit
This circuit functions as a night lamp when a wall mains socket is unavailable for plugging in a continuously operating small neon lamp device. To minimize battery consumption, it utilizes a single 1.5V cell, and a simple voltage doubler drives...
Battery-powered-ground-noise-probe
Oscilloscope measurements of ground noise can be unreliable because noise can enter your circuit via the scope's three-pronged power plug. This issue can be mitigated by utilizing the ground-noise tester described. The circuit operates on two 9-V batteries and only...
Light control delay circuit 4
A battery-powered light control circuit is designed to delay the lighting of a small lamp during sudden power outages or nighttime situations when a blown fuse leaves a room in darkness. This circuit addresses the difficulty of locating matches or...
Battery-powered fluorescent lamp circuit 1
The circuit described is a battery-powered fluorescent lamp system designed for temporary emergency lighting during power outages. It utilizes a transistor (V7) and a boosting transformer (T) along with an inductive feedback oscillator to generate a high-voltage output. When the...
