Introduzione LilyPad Arduino is one of the many Arduino microcontrollers, but unlike the more well-known Arduino UNO, MEGA and Yun, this little board has very specific characteristics that make it unique. In fact, the LilyPad can be sewn on fabric. In fact, with only 19 € you can add technology to our garments, but also […]

About this project Are you a maker?  Have you got a nice idea but could not verify it with a limited budget? Do you have a headache to design Wi-Fi products but cannot find a good support? Have you built a nice prototype ready for manufacturing but could not find the resources for mass production? […]

There are different types of DC-DC regulators. The most common are linear and switch mode regulators. Everyone that has tinkered with electronics has probably used a 78xx series linear regulator. They are easy to use since they don’t need any special components. With most linear regulators you just put a capacitor on the input and […]

This is a project that was inspired by Marc de Vinck’s Kitty Twitty Cat Toy http://makezine.com/22/kittytwitty/ . It incorporates an RFID reader and the BlinkM, a programable RGB LED. The lamp tweets random colored poems when it detects one of the three RFID cards which each represent one of the primary colors of light. These […]

First of all You won’t find here any information on high speed BLDC motor driving. For that purpose You need to know rotor’s position, so You have to measure back-EMF or use Hall sensors (not needed here). For basic info about driving BLDC motors here is best “classic” articles on internets: Driving a three-phase brushless […]

If you have ever wanted to control high voltages/currents with an Arduino, setup up a complicated light timer, or even have Siri turn on a Lamp. Then this is an instructable for you! In this instructable in a few simple steps we will build a self-powered smart relay (Arduino style) power box. This box will allow […]

Introduction Disclaimer: I am not an expert in any of this. There is lots of information online regarding such designs. Although this setup worked for me, do not trust any of my calculations. Please work all this out for yourself and consult many other sources, or it may spontaneously burst into flames. The contraption is […]

What it is… Type: Graphical (128×64) monochrome LCD with LED backlight Interface: Serial / SPI This is a good time to read the datasheet Available from: Adafruit, of course! Introduction: This mini-tutorial will go through the process of setting up a ST7565 LCD. These LCDs are   graphical which means they can display pixels, not just […]

Have you come out of a store and said to yourself, where did I park my car? Well, I have. Now, there are a lot of smartphone applications that can help you locate your car but smartphones are expensive. So this Lazy Old Geek (L.O.G.) decided to make my own. How It Works: When you […]

The use of low-dropout regulators, popularly known as LDOs, is common in many applications today because they provide a simple and inexpensive way to regulate an output voltage that is stepped-down from a higher input voltage. In addition, linear LDO voltage regulators contribute very-low noise as compared to switching regulators. Nonetheless, to keep system power […]
