In this post I have explained how a single LM324 IC can be used to create an adjustable voltage regulator circuit with overload and over current protections. Basic Working A basic IC LM324 quad operational amplifier regulates an unregulated 28-volt input source to approximately ±0.02%, resulting in a 1 amp 0 to -20 V supply. The […]

4 Simple Li-Ion Battery Charger Circuits – Using LM317, NE555, LM324
In this post I have explained a four simple yet a safe way of charging a Li-ion battery using ordinary ICs like LM317 and NE555 which can be easily constructed at home by any new hobbyist. Although Li-Ion batteries are vulnerable devices, these can be charged through simpler circuits if the charging rate does not […]
3 Tested 220V High and Low Voltage Cut OFF Circuits Using IC LM324 and Transistors
An AC mains high/low cut-off device will cut off or disconnect the mains supply from home electrical whenever a high voltage or low voltage situation is detected. In this way it ensures total safety to the home wiring and appliances from fire hazards, due to abnormal over voltages, brown outs or low voltages. In this […]
