Variable voltage source controlled by a dial. Proteus Adjustable Current limiting Linear Power Supply Proteus Adjustable Power Supply Library Requirements for the model to work: The model’s .dll file…
Battery balancer circuit is designed to control the charge thresholds of LifePO4 and Li-ion batteries. You can use it on Li-ion and LifePO4 batteries by changing 2 resistor values on the balancer. By adding transistor T1 and resistor R5 to the circuit, it was possible to convert TL431 into a Schmitt trigger. The divider R3,…
Classic analog ESR meter is a circuit based on SN74HC14N integrated circuit, it mainly consists of 150Khz oscillator, buffer, comparator and rectifier amplifier. The maximum range is approximately 75 Ohms and values below 1 ohm will cause some difficulty in reading the position of the galvanometer pointer due to the area used on the scale…
The circuit is a two-stage amplifier with the output transistor operating in linear A mode with a quiescent current of approximately 180 mA. The entire amplifier consists of OOS circuit (elements C5, R5, R6). The resistances of resistors R5 and R6 determine the gain of the node. The output transistor must be mounted on a…

Allows you to program ATMEL AVR microcontrollers in a DIP package. ATtiny, ATmega etc. There are 3 different projects for the AVR DIP adapter card. All of them have…
The purpose of the Charger is to overcome some of the limitations of the basic charger and offer users more flexibility. The advanced charger is based on similar hardware to the basic charger. The main differences are in the management of charge/discharge profiles, which can now be entered “locally” and without computer support. Differences from…
