New energy efficiency rules will change motor control design

Motor control is becoming the power industry’s fastest changing technology area. The reason for this is the requirement to improve energy efficiency from the millions of motors which are used in our homes, factories and cars. New developments in motor controller design, current sensing and control algorithms will be needed if new and more stringent efficiency targets are to be achieved. The main design elem ...

Window Painting Robot using Arduino

The idea for this project came from one of my favorite 'ibles: the polargraph. I loved the drawing style and thought how cool would it be to do this on the side of a building? Unfortunately the challenges to setting up such a large polargraph on a student budget pushed me to find an alternate solution, and thus started the window painting robot! This is a fairly simple robot that uses two neodymium magnets ...

ButtonHero using Arduino

ButtonHero is a game made on an Arduino that involves the use of buttons, LEDs, wires, and resistors. In this game, you have to hit the corresponding button to the light that is randomly selected before the light changes. You start with 5 lives and missing or being too slow subtracts one life. The high score is 56. Good luck! ideo of the Serial Monitor of the same game: http://screencast.com/t/PTaS3JwUu ...

Educational colorimeter kit

This instructable is a step-by-step assembly guide for the educational colorimeter kit we launched in April 2012 on Kickstarter. Assembly takes from 20-40 minutes. Once assembled the colorimeter can be used in a wide variety of science experiments to measure the absorbance and concentration of a colored solution. The colorimeter kit is an open source hardware project: KiCad files for the electronics, enclos ...

Designing and Building a 2m Low Pass Filter

I've been playing with the DRA818V modules that have been making quite a stir in the amateur radio world at the moment. I haven't gotten one on a spectrum analyzer yet, but I have reason to believe that it will require a low pass filter to be RF legal. I'll write more about that once I get a look at it, but figured I'd first built myself a low pass filter in case I need it (if not for these modules, but som ...

Blinky Lights using Arduino and LumiGeek

I used the Arduino UNO combined with three LumiGeek shields to run lighting. LumiGeek has dedicated shields to support 1 Watt RGB LEDs that require constant current, Addressable RGB LED Strip, and Non-Addressable RGB LED Strip. Step 1: 1 Watt RGB LEDs (2x) I wired these in series and powered them with the 12 Volt source on the Power Supply. The LumiGeek shield that powers these is the 3XCC - it provides con ...

Remote sensing with Arduino and XBee

Several years ago when I started messing around with Arduino and building my own weather station, I bought a few XBee radio chips with the idea of setting up some more remote sites without having to run wires out to the sensor stations. I spend several frustrating hours trying to get the radios to talk to each other, but couldn’t get them to work (I think this was because they were in API mode instead of AT ...

Control an Arduino With a Wristwatch

The watch The Texas Instruments eZ430 Chronos is a cool gadget. It has bidirectional radio communication, and a whole bunch of sensors: temperature, pressure, acceleration. In fact, it is a development kit for the MSP 430 (a low-power microcontroller), that TI packaged as a watch (pure genius!), and delivered with plenty of tools. Its firmware can be modified to implement new features into the watch. Even w ...

Servo 360 rotation mod (Parallax)

In this instructurable I will expalin and show you how to make a Parallax servo rotate 360º. And againI have search the internet to see tutorials clear enough to make this posible with no luck. Don't get me wrong they are some how good but not clear. This mod will help you to use the mod servo for robots that need a fully 360º rotation servo. Also some of the pictures were taken from other instructurables a ...

Wireless Power Outlets RF from Raspberry Pi

Thanks LifeHacker and HackADay for featuring my post. If anyone has questions please leave a comment below and I’ll be happy to help! Have you ever wanted to wirelessly control power outlets from your phone? You could buy a Belkin WeMo Switch for over $40 for 1 outlet or build your own with 5 outlets for under $35 if you already own a Raspberry Pi. Hopefully this post will guide you in the right direction. ...

Wu-Tang Can: Interactive Tipping

Cash rules everything around me. C.R.E.A.M. Get the money. Arduinos are showing up everywhere. Even in space. But what about the lowly tip jar? No. Are Arduino projects giving the Wu-Tang Clan the proper respect they deserve? Not even close! Rectification. That's what this is about. Interactive tipping. Dolla dolla bill y'all. Step 1: Materials Here's what you need. Materials: Can - My can used to hold bean ...
