Simple Lithium-ion / Lipo Battery Charger

This is a Lithium-ion charger for lipo batteries. Circuit schematic shows configuration for charging single 3.7V lipo battery but voltage can be set to charge several batteries in series. Lipo charger sets a current limit with the LM317, and 1 resistor, and the voltage limit with the TL431, and 2 resistors. 1K resistor is needed to let the TL431 decrease the LM317 current, and to provide the necessary current to the TL431. The optional Schottky diode at the output will prevent current flowing ba.......

How to build Fully Automatic Emergency Light - circuit diagram

The circuit can be divided into inverter and charger sections. The inverter section is built around timer NE555, while the charger section is built around 3-terminal adjustable regulator LM317. In the inverter section, NE555 is wired as an astable multivibrator that produces a 15kHz squarewave. Output pin 3 of IC 555 is connected to the Darlington pair formed by transistors SL100 (T1) and 2N3055 (T2) via resistor R4........
