This is the PCB from https://github.com/vhs/vhs-pcbs/tree/master/usb-isolator. No components are included, PCB only. In one of the earlier SMD workshops I’ve running at VHS I managed to temporarily kill my new MacBook pro when I plugged in a participant’s prototype. I revived it by removing the back cover and disconnecting the battery all the time chanting to […]

What can you make with fluorescent acrylic as the inspiration?  We chose to make a glow-in-the-dark baby mobile, with an accompanying toy.  This project was completed as a part of the Computing and Craft class at Olin College of Engineering. Materials: – Craft Materials: – Fluorescent acrylic (1 square foot of each of the following […]

This instructable describes how a simple but powerful webserver used for controlling of home appliances can be done. The hart of the circuit is the ATmega328 microcontroller. I have chose this because I wanted to use all available Arduino libraries compatible with them. The Ethernet chip used is ENC28J60. A lot of Arduino libraries exist […]

This is the story of how I made my first robot, and the instructions to build one yourself. It’s a simple line tracer, controlled by two op-amps. No microcontroller, no programming… simple analog circuitry. I tried to make it as small as possible, using SMD components and tiny motors. I’m very happy with the final […]

You’ve bought your first Arduino or you’re planning to get this great little device? Obi Wan would say: “That’s good. You have taken your first step into a larger world.” Same thing for me! Congratulations! You’ll see, as soon as you master the basics, you’ll have so much fun with this little device. There are […]

News: In this latest months I’ve made some important fixes and improvements to the code and to the webserver of the project. See datura_mega_v19.ino for the latest code. The most functional project over internet – Use it as a complete irrigation system for your garden, or use it to control your aquarium, or just to […]

This example shows you how to read an analog input on Pin 0, convert the values from analogRead() into voltage, and print it out to the serial monitor.  Circuit: image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect the three wires from the potentiometer to your Arduino board. The first goes to […]

The VL6180X is the latest product based on ST’s patented FlightSense™technology. This is a ground-breaking technology allowing absolute distance to be measured independent of target reflectance. Instead of estimating the distance by measuring the amount of light reflected back from the object (which is significantly influenced by color and surface), the VL6180X precisely measures the […]

Reborn is an australian digital creative agency whose mission is to design smart and innovative ideas. Among their works, a very nice one regards a hack consisting in the re-engineering of a sofisticated espresso machine, to show its peculiar features in the process of coffee making. By means of an Arduino board, the team can collect real-time information such […]

For my project I created a robot with an attached water cannon. My mentor and I built it in a budget of around $300 (not including the necessary equipment), and it functions quite well. For the motors we used drill motors, powered by the 18 volt drill batteries. To control it all we used an […]
