First of all, this is jst a first prototype. It works but I can't know all the results for sure and if it is reliable or not. Stay tuned for future versions with improvements, more tests and better code. In this tutorial I will explain you the parts of an MPPT controller, the charging proc... view more

The idea behind this tutorial is to make somethiong like this module here that you could buy from eBay, but make the homemade version. This is a radio controlled relay module. This tutorial will show you how to make the remote controller and the receiver with the relay. The receiver ... view more

In this tutorial I show you how I've build a homemade electronic load with Arduino, an LCD, rotary encoder for the menu and a power MSOFET for load control. It also has a good cooling system so it could handle high loads. See how to make the circuit, the case, connect everything, see the code I'v... view more

This is a very basic tutorial. I will show you how to build a constant load controller. What is that? Well, imagine you want to test the efficiency of a power supply. At a certain voltage output, you should create a current values table and get the effiency curve. For taht you need different valu... view more

Yes, I've made another radio controller. Why? well, I wanted to have a more commercial look. So, I've designed a 3D case, then I've used some high quality joysticks in order to have better analog read, It has an OLED screen so we could see the data we send and we could also digitally adjust the d... view more

In a past tutorial we have build an ESC for sensor-less brushless motors. Without sensors we had to implement a back electromotive force detection and make the switching sequence with that. The circuit got quite complicated and the code wasn't the best neither. So, in this tutorial... view more
