Hey, we all LOVE the Arduino, and for my projects I make extra sure that I used the Arduino platform, so that everyone in the artist and hacker community could springboard off it for their own projects, and so that I can springboard off them. Its so universal and easy to learn! But, there are a few things THEY don’t want you to know about the Arduino…

Libelium has introduced their 3G/GPRS shield for Arduino (3G + GPS). It enables connectivity to high speed WCDMA and HSPA cellular networks, and includes GPS. [via]
The GPS module also makes it possible to perform geolocation services even in indoors as it can work in A-GPS and S-GPS modes, so the location given by the GPS through NMEA sentences is completed with the cell information provided by both the 3G module and external Internet Geoposition Servers which helps you to get the most accurate location in each case.

This project explains how to use thermistors to measure temperature, using the Arduino platform. The method shown executes quickly, using a lookup table with interpolation for greater precision. The thermistor used in this example is a
3950 NTC, 10K @ 25 Deg Celsius. [via]

An Arduino based burglar alarm that sends an SMS when motion is detected. It will send an SMS to you every 30 minutes while motion is detected (configurable).

ZPUino is a system-on-chip 32bit microprocessor FPGA core, that functions with a modified Arduino IDE. All the files regarding the core are open-source and downloadable from their site, and so is the modified Arduino IDE. [via]
Yes, that is true.
ZPUino 1.0 is now available for you to use and enjoy. Expect some updates on next few days – release cycles are about to change, we’re switching to release early, release often. As always, direct any questions to zpuino @ alvie.com.

Mint-Sized Success Meter (quit smoking!) with Arduino – [via]
There comes a time in life to put childish things behind and give up nasty habits. Some, like smoking, can be damn hard without constant encouragement. It was time for me to combine my favorite hobby with my driving goal and make this: The Quit Success Meter!

Measuring Battery Capacity with an Arduino. Dennis writes- – [via]
I needed a couple of AA batteries and found the display at the supermarket where they were all arrayed. Normally when I’m shopping in the supermarket, I tend to look at the price/kg or price/l when comparing similar products. In the case of the batteries, there was no such indicator. Fine, I thought, I’ll work it out myself. I grabbed a few different makes and scanned the packaging for some measure of their capacity. Nothing. Not a single one of the batteries had any indicator of how much energy they would provide. Instead, they all had terms like ‘PLUS’, ‘SUPER’, ‘ULTRA’ and of course had wildly differing prices. So, I decided that it was time for an experiment and bought one pack of every type I could find.

This how-to takes you through all the steps of making your own arduino on a perfboard or perfduino! Arduino microcontrollers are great for learning about physical computing and are very useful for rapid prototyping. Arduino’s simple programming language makes it a favorite of hobbyists and diy-ers around the world. Because arduino boards range in price from 30 to 70 dollars, it can be very cost effective to make your own. This lets you customize the layout of the board and brings down the cost so you can embed your perfduino in a final iteration project without losing your precious professionally made arduino board you had to wait so long for by the mailbox. The perfduino in this tutorial is designed to closely mimic the original arduino functionality without any specific project layout in mind.

The Ard-Vark is a basic electronics box that can be remotely controlled by an app on your iPhone, iPad or Android phone. It is Arduino compatible. Have you ever wanted to build a project that needed electronics but you didn’t know how to start? Would you like to add motion to one of your creations, and be able to control it with your phone or tablet and not have to learn electronics, soldering, programming and a few hundred other things? Then the Ard-Vark is for you.

swim with a triathlete group in an outdoor pool at 6AM three days a week. For half the year I can see stars when I start swimming. What I can’t see in the dark is the analog clock to check my pace on 100 meter laps.
To solve this problem I designed and built a portable digital timer with LED display. The 4-digit 7-segment display is large enough to see from 10 feet away so I can read it without stopping. The timer is encased in a transparent and waterproof polycarbonate tube so that I don’t have to worry about it getting wet or falling in the pool. In fact you can take it to the bottom of the pool and it won’t leak. Normally it just sits on the edge of the pool where I can see it.
There are a variety of LCD swim timers available that are fine for day swimmers. This timer is for night swimmers.
