There are many charge controllers available, but ordinary cheap ones are not efficient enough to use with maximum power from solar panels.
This is a model circuit that can control the speed and the direction of a dc motor without the h-bridge ( it's an alternative to h-bridge ).
CAN bus hack for reading the battery diagnostics form an electric car.
Get your essential appliances off the grid with just one solar panel
Embellish, protect and reduce the sheet metal look of your modified HP server power supply with this 3D-printed enclosure.
This hack is a proof of concept that shuts off power only to the level of the house that has been flooded, allowing for normal use elsewhere
This project is a "from scratch" DC regulated benchtop power supply intended to be used by an electronics hobbyist.
In this post we are going to construct a three-phase inverter circuit using Arduino and MOSFET. We will have a brief look at the three phase
In this project I tried to overcome a very common issue while working on a portable electronics project. That is how to power my circuits
A compact, feature-rich smart UPS for Raspberry Pi boards.
A symmetric power source for audio amplifiers controlled by the Arduino's PWM with max output +-30v 10A.
12v Solar Generator using a Victron BlueSolar MPPT 75/15 Solar Charge Regulator & Arduino-based GUI for Info Display.
Allows quick evaluation of Power Supply Plant parameters for TI Buck_VMC_F2837xS project.
With a code size of 1KB on an ATtiny13A MCU, this tiny module measures voltages up to 22 volts and current up to 5 amps.
How to make a variable step-down DC to DC converter using TPS54331.
Power up your Raspberry Pi and use the RS-485 without unreliable USB connectors and additional adapters.
Open source DC boost converter module designed around a single cell lithium battery: 3.7 V in, 5 - 24 V out.
What should you do to safe battery.
Make a dummy load for a lower voltage DC power supply. Very good if to test a power supply you got or if you are trying to make one.
Make your own adjustable voltage solar charger.
Ethernet Development Board for Raspberry Pi RP2040 with POE Capability,
Every engineer needs at least one bench power supply in his house. I agree one can get the power supply directly from the store. How else?
How to build a professional 30V 4A adjustable bench supply using the ZK-4KX Buck-Boost Converter and a old laptop power brick.
A tiny DC to DC buck converter board is useful for many applications, especially if it could deliver currents up to 3A.
