I've seen this idea on twitter and I wanted to make a homemade one. Is a nice product as humidifier but also as a huge smoking capacitor. You can 3D print it and make the same project with ultrasonic mist generator. Get the 3D files, the schematic and the part list from below and make your... view more

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
