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...
In this project we will build a low cost **5V booster circuit** that provides a constant regulated output voltage of **5V from a CR2032 coin cell**; we will also design a compact PCB for this boost converter so that it can be used in all our future portable projects. The maximum output current of the boost converter will be **200mA **which is good enough to power basic microcontrollers and sensors...
<h1>VM's Power Latching Circuit</h1>
<p>Simple circuit that waits for external signal (button press, sensor going ->HIGH or -> LOW) and then provides power for microcontroller. After boot up the MCU uses output signal to keep the power on. After data processing, the MCU can shut off its power, therefore saving energy.</p>

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...
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 ;)
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
ERROR IN THE SCHEMATIC... DON'T MAKE IT UNTIL I CHANGE IT IN A FEW DAYS. SORRY FOR THE INCONVENIENCE. I WILL POST WHEN THE SCHEMATIC IS REVISED.
A modern take on the original Tesla Coil using electronic circuitry; this specific type is a Dual Resonance Solid State Tesla Coil. This is based on Steve Ward's original design at http://stevehv.4hv.org/SSTC5.htm and updated for modern and easily available components.
A simple pcb to easily measure the amp/current usage of a eurorack module. Add a jumper on each rail in the middle, and take the jumper away on the rail you want to check. Connect power in on one side, and the module on the other. There is a super short video showing how to measure and how it look like when it is done here: [https://youtu.be/46zdCIhjmmg](https://youtu.be/46zdCIhjmmg)
