LM2576-ADJ Adjustable Power Supply Circuit

| 2017/10/01

LM2576T-ADJ Power supply DC DC through long cables is associated with the voltage that is the greater, the longer the cable length and the current drawn by the receiver. Sometimes this fall is so big that the receiver is not working properly. The presented regulator compensates for this by measuring the voltage at the receiver…

ATMEGA48 Timer triggered by current flow ASM-010

| 2017/10/01

ATMEGA48 Many devices may be in standby mode during downtime. They do not perform any work, they are apparently disabled, but the control circuits are powered. To extract useful information from the point of view of working time, you should download it from the inside of the device, which may end up with a loss…

MCP73833 USB powered Li-Po charger Circuit

| 2017/10/01

LiPo batteries are increasingly becoming a primary source of power, replacing other chemical sources of energy. The upgraded device, powered by a USB port or a mobile phone charger, allows you to charge medium capacity LiPo cells with critical operating life and operational safety. Compared to the previous one, it offers higher current charging (up…

230V Fan Regulator Circuit Mosfet MC33152 ATtiny25

| 2017/10/01

Brushless asynchronous motors, with compact rotor windings, called short cages, are used to drive different fans. Their advantages are durability and simple construction. The presented layout uses a certain characteristic of such a fan to regulate its rotational speed. The operation is based on a group control method – the motor is powered by a…
