Audio player powered with Siemens SDI TAPAS, a 48V GaN (Gallium Nitride) based three phase community inverter board with onboard filters.
In this project, I will share some of the techniques used by my low-cost robot car projects.
A single cell power bank which is used to power up battery operated devices. It can supply a constant power to the load.
A pocket, rechargeable battery PSU for powering small Cosplay-related projects (and not only)
Easily repeatable 120W bench power supply circuit. Cheap, fast project.
Lots of makers find themselves running out of space quite quickly, this mini power supply helps solve this issue.
I made this transistor based stereo preamplifier board to control the volume, bass and treble of my previous build TDA2030 amplifier.
Have you ever wanted to spice up your party environment with lights? This project uses two Particle Photons, a photoresistor and LED lights.
A core IoT system powered by Solar and Wind power.
Protect your circuits with a powerful and resettable E-Fuse when handling circuits with high current batteries.
A transportable and stackable 12V PowerBox with laboratory clamps and Arduino powered voltmeter. Useful to tinker everywhere you want.
This is a very simple way to make a pretty decent, but cheap benchtop power supply out of mostly old PC parts.
This is an Arduino compatible shield which is able to measure the real time current, voltage and power ratings accurately.
Learn how to power your Raspberry Pi Pico W projects easily and flexibly with the MB102 Power Supply Module for a clean, reliable setup!
How to make sure your software runs on your hardware for years on a tiny battery
The device utilizes the Pyroelectric Infrared Sensor to automatically power down the electric power to the tools at the work bench if idle.
A battery charging module to charge 1s/2s cells, based on buck phenomenon.
A 200w HiFi mono amplifier with signal gain boosting options. This is TDA7294 class AB ic. Let's boost the power with TDA
A small and easy to made project with Arduino. This project tell about voltage, current and power measuring.
A compact voltage convertor board that can generate a dual rail power supply from a single battery source.
Showcase on how to go around building your SMPS
SCADA for load shifting with my 21 KW hour battery. Featuring Google charts script generated by the ESP32.
In this entry, you'll find how to add a USB power port to a network switch for powering devices like Arduino to connect it to the cloud.
Now it is time to get start with my own designs of class D amplifiers. This is the base article to getting started with 2.1 Audio amplifier
