I recently bought an e-paper display with a 2.7" screen size distributed by Embedded Artists. Since it does not consume any power between updates it is perfect to display status information for any kind of embedded technology. Since I am quite the Arduino fan my plan was to hook it up to one of them and simply use an existing software library to interface it. (Update available)(second Update)
for my first post that actually contains content, I would like to show you what I use as a cheap and small GPS device.
GPS devices can be found in a lot of different devices, like mobile phones, cars and security devices. One class of such security devices are GPS -Tracker. GPS-Tracker constantly register their position and send the information to a previously specified user via eMail or SMS. I bought this tracker (for ~60€) that sends a SMS with the current position as a reply to a request SMS coming from me. The initial idea was to get the position of a RC plane in case its lost or to track the position of my cat 🙂
