Battery charging regulator
The circuit is designed to charge a 12-volt component selection at a maximum current of six amperes. Once the battery voltage reaches its fully charged level, the SCR shuts off, and a trickle charge, determined by the resistance value of...
Heavy duty battery charger
The operational amplifier A1 directly drives the VN64GA with the error signal to control the output voltage. The peak rectifier D1 and capacitor C1 supply the error amplifier A1 and the reference zener. This additional drive voltage must exceed its...
Lithium Ion Lithium Poly Charger by LM317
The circuit is designed to charge any 2-cell Li-Ion battery pack, with a maximum current output of approximately 650 milliamps. It is suitable for batteries with a capacity of 900mAh or higher. This circuit is not compatible with Li-Metal batteries...
Solar Powered Robot
Construct a low-cost and relatively simple robot that activates whenever a desk lamp is illuminated. The design does not incorporate any sensors.
This robot can be designed using basic electronic components to create a simple activation mechanism based on light detection....
Portable Solar Lantern
This portable solar lantern circuit utilizes 6 volt/5 watt solar panels, which are now widely available. With the assistance of such a photovoltaic panel, it is possible to construct...
The portable solar lantern circuit is designed to harness solar energy through...
solar panel lead acid batteries charger
This battery charger is designed for charging sealed lead-acid batteries using a solar panel in portable applications such as baby carriages. The standard diode that prevents the current from flowing back through the solar panel has been replaced with a...
Low/Zero-Carbon Office
The intention is to genuinely and measurably reduce energy consumption and/or micro-generate energy, leading to a net reduction in the energy imported to a residence each year. Since 2007/2008, all office lighting has been transitioned off-grid, achieving a zero-carbon status...
Nestbox Solar Powered Wireless CCTV Camera Circuit
The circuit is designed to power a CCTV camera, provide lighting inside a nestbox, and charge batteries using a photovoltaic (PV) solar panel. It includes a circuit diagram for a solar-powered wireless CCTV camera with battery backup. D1 is a...
Lithium Ion Charger 2 Cell
The charger operates by supplying a short current pulse through a series resistor and then monitoring the battery voltage to determine if another pulse is required. The current can be adjusted by changing the series resistor or adjusting the input...
