Arduino controlled rover with FPV live video

Posted on by Leave a comment

Tamas is a 17 years old electronics enthusiast from Hungary. His latest creation, which he shared on Instructables, is an Arduino-powered rover that can be controlled with brainwaves or a joystick. The best part of it is, while it’s being operated, you will also have access to a live video stream from the mounted camera via your pair of virtual reality glasses. This is an all terrain vehicle, that means that you can control it on snow, sand, any kind of ground, wet surface and of course indoors. It is powered by two 18650 lithium-ion batteries with a capacity of 2600

Analog thermometer

Posted on by Leave a comment

A new project tutorial from educ8s.tv is about making an Arduino based analog thermometer that uses an analog voltage panel meter for displaying temperature. Today we are going to learn how to use this analog voltmeter with Arduino and make it show the temperature instead of the voltage. As you can see, in this modified voltmeter, we can see the temperature in degrees Celsius. The temperature is measured by this digital sensor, a DS18B20 and it is then displayed on the voltmeter. I really like analog dials like this one, because they give a vintage look to the projects. Let’s

Arduino powered vending machine

Posted on by Leave a comment

An Arduino-powered soda locker project posted by Mistablik on Instructables can easily fit into his locker and can supply two different kinds of pop. It features a coin acceptor that allows you to use nickels, dimes, and quarters for purchasing the soda. Lockers just aren’t what they used to be. With so many schools moving to electronic devices for books, lockers become less of a space for your books, and more of a question of: “What am I going to do with this?” What if you could use that space for your own vending machine? In this Instructable, I’ll tell

Making a high-current bench-power supply utilizing ARTESYN NXA66 regulator module

Posted on by Leave a comment

Andy Brown explored reverse engineering the ARTESYN NXA66 regulator module to build a cost-effective bench-power supply with high current supply capability. NXA66 is a non-isolated dc-dc converter targeted at computing applications that require precise voltage and fast transient requirements of today’s high performance applications such as workstations, file servers, desktop computers, telecommunications equipment, adapter cards, DSP and data processing. He designed an Atmega328 driven controller board that would host the NXA66 and expose its functionality via a front panel consisting of seven segment display modules. I’ve included a relay between the 12V input and the NXA66 because I don’t want the
