supply AC6 - 12V to this and the circuit will convert the input to DC 5V (YOU CAN CONNECT A TRANSFORMER TO THIS).IT USES A RECTIFIER BRIDGE TO CONVERT FROM AC TO DC. theres not much to explain about this circuit so.. if you have any questions, plz ask in the comment section an ill repla ASAP.
hope you like my project ;)
Arduino Mega ADK based project to allow remote control of computer's power state (IPMI style working with any computer).

Using the EasyEDA pwrmeas and resmeas probe spice symbols to make instantaneous power and resistance measurements.
The pwrmeas probe calculates power from the instantaneous voltage across the device multiplied by the instantaneous current through it and is represented as a voltage scaled as 1V/Watt. The output of the pwrmeas probe therefore needs to have a voltage probe attached to it in order t...

Este circuito se basa en el popular regulador de tension 7805. Dispone de un diodo a la entrada para protegerlo en el caso que se aplicara tensiones con la polaridad invertida. El condensador C4 reduce considerablemente el rizado de la tension de entrada que finalmente el regulador 7805 se encarga de estabilizar a los 5 voltios de alimentacion de todo el modulo. Por ultimo dispone de un diodo LED...
Still in progress.... need to doublecheck schematic
THIS IS NOT MY DESIGN, its very old from a magazine 20 years ago, and its modified elektor schematic from 1982 i think
Description soon
These are transformerless power supplies that can feed 5V circuits with current consumption ranges from 20-30 mA to 80-100 mA. Check the C or R values and the configurations.
You can simulate to measure supplied voltage and current. The model for Zener diode is on schematics for it.
Change values and get your needed output current.
The bridged capacitive version worked fine for a 50mA circuit...
Печатная плата для светомузыки (проект AlexGyver). В плате предусмотрено:кнопка управления (v1.0), микрофон, потенциометр (регулятор шумов), IR приемник для пульта управления, транзитный JACK 3.5, питание с PWR JACK, клеммника и просто 2PIN разьема, выбор питания (5V & 12V), выбор источника аудио (микрофон & JACK). Кстати: размер платы 30мм*48мм, а следовательно можно заказать аж 30 штук за 2$)) Е...
В проекте представлена простая конструкция ШИМ-регулятора, с помощью которой можно легко переделать компьютерный блок питания, собранный на контроллере, отличном от популярного **TL494**, в частности, DR-B2002, DR-B2003, SG6105 и прочих, в блок питания с регулируемым выходным напряжением и ограничением тока в нагрузке.
A smart power saving in line power switch designed to remove mains power from a TV or other device in standby to reduce electric cost.
This design uses any infra-red controller with a 36 - 38kHz carrier. A long press of any IR button on the users remote controll will cut the mains power, a short press on any button will restore the mains power.
An override button is also on the power switch to s...
