Comprised of seven servo actuated felt markers controlled by an Android handset via an IOIO board, the Cellular Wall Printer allows you to manually […]
“follower” wrote in with yet another cool project for the Android Open Accessory SDK. This time, you don’t even need to do any Android programming; your Arduino Sketch tells follower’s Android app what to do and what to display on the screen: Handbag makes it possible to create Arduino-based accessories for Android devices without creating […]
Not long after the Open Accessory Kit was announced, romfont posted a great set of instructions on getting this work with a standard Arduino.
Walking, rolling, floating, and swimming among the packed crowd at the Google I/O afterparty were numerous robots autonomous and otherwise under the influence. If you were to drop by the Maker Faire booth you would have gotten the chance to try your luck at navigating the slalom course with Brian Jepson’s 3D printed Slalombot using an Android smartphone’s accelerometer.
I made a sample app using the normal Android development process, put it on my Nexus S (running normal OTA Android 2.3.4), and plugged it in to my FEZ Domino. Now I can turn on LEDs and push buttons and everyone has a good time.
Yesterday, Google announced their open accessory kit based on Arduino. Although they aren’t immediately available for sale in the US, they (or something like what you see in this post) will be soon.
OK, so, maybe the fact that, under vacuum, Scotch tape will emit enough hard x-rays to image the bones in your finger is slightly more impressive, but this is still a pretty cool trick.
