Planet Arduino

While [Ilias Giechaskiel] was waiting for his SIM900 shield to arrive, he decided to see what he could do with an old Nokia 6310i and an Arduino. He was researching how to send automated SMS text messages for a home security project, and found it was possible to send AT commands via the headphone jack of Motorola phones. But unfortunately Nokia did not support this, as they use a protocol known as FBus. With little information to go on, [Ilias] was able to break down the complicated protocol and take control with his Arduino.

With the connections in place, [Ilias] was able to communicate with the Nokia phone using a program called Gnokii — a utility written specifically for controlling the phone with a computer. Using the Arduino as an intermediary, he was eventually able tap into the FBus and send SMS messages.

Be sure to check out his blog as [Ilias] goes into great detail on how Nokia’s FBus protocol works, and provides all source code needed to replicate his hack. There is also a video demonstration at the end showing the hack in action.

The buzzer on a washer or dryer may be OK for most people, but what if you would like something a little more versatile to tell you when your laundry is done? Here’s an interesting solution involving an Arduino Yún that sends a text message when the washer or dryer […]

At work, I often use a Post-it note stating my whereabouts on my office door for those who stop by looking for me when I am out. Some notes are one-time use like “On vacation. Back on 11/20.”, and some can be reused like “Up in the 3113 lab.” Sometimes, […]

We remember several years back, when text messaging was first becoming popular, we went to a bar which had a huge television that would display text messages sent to a particular number. This sounds like a novelty, but in a large group of folks who know one another it’s the sandbox of social games. Wanting to tap in on that fun for his New Year’s Eve party, [James] built this countdown timer that includes an element of SMS interactivity.

The rig is projector based. A computer using Processing does the majority of the work but [James] needed a way to accepts text messages (the locale of the party had no Internet connection so this was the best bet). He grabbed a GSM shield and his Arduino Leonardo. The bulk of the evening the display showed the last few messages received, with a small countdown timer in the lower corner. As the countdown approached zero the time was given prominence as in the image above. We guess he was lucky to find a prepaid SIM card that allowed free incoming text messages. Our cell provider charges us 20¢ for each.

You might give this one a whirl next year. If it’s not quite your thing take a look around. We’ve seen a lot of fun setups like this mini ball drop.
