Although products are becoming more and more available for monitoring your home power usage, I’m one of those idiots who can’t leave well enough alone and who would rather shell out $100 and hours of my time in order to save $20 and learn something in the process.  Building on the fine work of Trystan […]

A while back, we constructed a pair of LED skateboard truck-risers. That project was intentionally created without the aid of advanced tools and techniques. We decided to try the concept again but without limiting ourselves. This time around we used custom designed PCBs and 3D printed parts. There was no limiting ourselves to hand tools and […]

Ever wanted to have a Phone Book, controlled using a microcontroller, which is very easy to use, and you can use it while talking on phone, and is saving data on SD Card? then this instructable is for you. In this instructable you will learn how to make an arduino controlled Phone Book, and you […]

So we haven been working on the new soundgraffiti board. This is an installation wich creates sounds using sprayed water. The connection is made with water. We used copper plates as our sensor. the plates had a cutout line in the middle of 0,1 mm. Once water hit this line it would connect both sides […]

In this week’s arduino tutorial, we take a bit of a detour and focus on some key elements of electrical engineering design that we’ll be using in future episodes. Included amongst these topics is Ohm’s Law, current-limiting resistors, pull-down and pull-up resistors, voltage dividers, potentiometers, analog inputs, and voltage regulators. If you’re yearning to learn […]

Many years back when I was still quite heavily involved in the day-to-day company IT matters, we need to subscribe to a service called “Smart Finger” when we put our servers in a datacenter. Basically what this service is all about is to allow datacenter technician to help us to press the power or reset […]

With this device you diminish the use of water in your house or work. Instead of waiting to see vapor in the shower to get in, this device help you to know when the water its at the temperature you want and you can instantly enter to the shower. In this way you don’t waste the water […]

The objective is to construct a programmable hobby bot that is affordable and simple to make. The parts will be purchased from places such as Wal-Mart, Radio-Shack, any Hobby Store, or online store that is accessible to the public. The price range is 50 dollars or lower for the entirety of the robot. Step 1: […]

Recently I’ve been learning about Ultrasonic waves and how to harness their power. It’s simple enough to make some type of sonar device, but I wanted to take at a step cooler and see if I could use Ultrasonic waves to not only detect movement, but also the direction of that movement. So let’s take […]

Interrupts are an extremely useful, yet often feared element of microprocessors. Interrupts allow you to run a program, while still being able to react to asynchronous input from the outside world. On many platforms they can be confusing to implement, but the arduino makes it easy! In this week’s episode, I’ll show you how to use […]
