We are going to buil a nice and fun radio controlled airplane. To make this project even better we are going to 3D print a real replica of the war Spitfire plane. If you don't have a 3D printer, there will be other tutorials on how to build a plane out of wood, foam or cardboard. The rest of the ... view more

COVID-19 can seem like a paper tiger, when looking at bare mortality rates. The far greater problem is the increase in fatalities as health systems are stretched to the limit. With thousands of patients presenting all at once, hospitals quickly run out of beds and resources and suddenly, normally... view more

In this tutorial we will see how to make a Magic 8 ball with the Arduino. This is based on the real magic ball which is based on liquid and floating principle with a plastic dice with 20 answers inside. Once you shake the ball, a random side of the dice will get on top of the black liquid and a r... view more

This is a very simple project that uses the Adafruid library to control a RGB adressable LED strip that will eb inside of a Daft punk Helmet. In this tutorial you will find the STL files to 3D print the plastic helmet, the schematic for the LED control with Bluetooth and the Android App that I've... view more

In this tutorial we will merge all the parts seen in these past tutorials here. In those tutorials we have seen how to measure resistance, current, indcutnace and capacitance. Measure voltage is very easy. In this tutorial we make a 5 in 1 multimeter based on an Arduino, an ADC module and an... view more

A few weeks ago I've made this radio controller based on Arduino and the NRF24 radio module. Now we can see how to use it. We start with something easy. Servos are controlled with PWM signal. What we do is receive the radio signal, crewte PWM signals and control the servo turret. We als... view more
