Tutorial - HOMEMADE ULTRASONIC DISTANCE SENSOR

We will make a homemade ultrasonic distance sensor and see how these modules work. The working principle is quite simple but the circuit could get a bit tricky. We send a ultrasonic wave with the transmitter speaker, the wave hits an obstacle and bounce back to the receiver speaker. We calculate ... view more

Tutorial - 6S & BMS BATTERY PACK

This is a very basic tutorial and there are already a lot of guides on how make something like this. But, since this is part of a future project (electric longbaord), well I'm doing this first step and show you how to connect the batteries, add charging protection. I'll use some Samsung INR18650 ... view more
