Lernstift Digital Pen Hits Kickstarter for $150

Lernstift is a digital pen running Linux that aims at helping children learning how to write by vibrating when they’ve made calligraphy or orthography errors. I’ve covered the overall concept in an earlier post, which you can read for details. The company has made some progress, and they have just launched a kickstarter campaign where you can pledge 99 GBP (about $150) to receive the pen later this year or in early 2014. We do know a little more technical details. The first prototype was based on Gumstix Overo (TI OMAP3 or Sitara), but they are now working to design a custom board based on the platform for the final design. The pen comes with 128 MB RAM and runs embedded Linux. In order to gather handwriting data, Lernstift leverages a motion sensor that combines gyroscope with accelerometer, and adds a magnetometer. They’ve got a drawing with Freescale MMA9950L, but it’s not quite sure whether they’re using this chip or …

Lollybot is a $10 Robot Made with a USB Gamepad and Chupa Chups

I attended Barcamp Chiang Mai 6 yesterday, and sessions dealt with a wide range of subjects ranging from SEO and web development to things like nuclear energy, VMAT2 God gene, or Edward Snowden. There were just four talks somewhat related to the subjects I usually write about in this blog: Project Manhattan – An interactive TV infrastructure project for TV operators based on open source libraries (but not open source itself). They provide both back-end software and a mobile app (Android or iOS) for smartphones and set-top boxes. They had an Android set-top box, but unfortunately there was no time for demo. There’s no project website, but the solution is said to be used by horizon-tv.tv (in Russian). A Raspberry Pi session which I could not attend Firefox OS – Keng is the owner of a mobile and web development company called opendream, but he’s also one of the 4 Mozilla core developers in Thailand who mainly work on Thai …

Lernstift – Linux Based Learning Digital Pen

Lernstift UG, a German startup, is working on a digital pen, called Lernstift as well, that can help children learning how to write by vibrating in case of errors. The Lernstift can be used in 2 modes: Calligraphy Mode – Pointing out flaws of form and legibility. Orthography Mode – Detecting orthographic (1 vibration) and grammatical (2 vibration) mistakes. Since it features a ballpoint, it can be used as a real pen, you know to write on paper…, but you can also write in the air, so I suppose they’ll also make a version without ballpoint, so that kids can enjoy one of their favorite pastimes: writing on the walls! The pen features a CPU module (2) that’s used to handle handwriting recognition, gather data from the motion (1) and pressure (3) sensors, and manage the Wi-Fi module (4). A battery, a power switch, and a pen refill complete Lernstift design. The pressure sensor won’t be included in the first …
