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

In this instructable / video I will show you how you can make your own variable lab bench power supply which can deliver 30V 6A 180W (10A MAX under the power limit). Minimal current limit 250-300mA. Also you will see accuracy, load, protection... view more
