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 […]

This is How the BeagleBone Black is Manufactured

CircuitCo has recently uploaded an interesting “Make of the BeagleBone Black” video showing how the BeagleBone Black is manufactured in their facilities in Richardson, Texas, USA. The main steps are as follows: A machine applies solder paste to the PCB Pick and place components Reflow soldering for SMT components Hand placement of through hole components such as the Ethernet connector Selective soldering PCB washing Optical inspection via an automatic optical inspection (AOI) machine Manual inspection Burn-in tests after flashing the board with factory firmware Functional testing Packing and shipping Beside the overall process, one interesting point is that human hands are only involved with through-hole components placement, functional testing and packing & shipping. Even those steps may eventually be automatized in the future with robots such as Baxter. Watch the video, it’s worth a look. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his […]

Linaro 13.05 Release With Linux Kernel 3.10, Android 4.2.2, and Ubuntu Raring Ringtail

Linaro 13.05 has just been released with Linux Kernel 3.10-rc2 and Android 4.2.2. This is the first release with Ubuntu 13.04 (Raring Ringtail) images. There’s also Linux Linaro Stable (LSK) preview based on kernel 3.9.4. BeagleBone Black support has been added and preliminary hwpack and images are available, an Android Arndale image with virtual framebuffer is also available. You can now get a desktop environment (XFCE) on Aarch64 / ARMv8. Hardware packs with Real-time Linux kernel (PREEMPT_RT) can be downloaded for Pandaboard and Arndale. More work has gone into Aarch64, big.LITTLE HMP, and ARM virtualization (KVM). Finally an UEFI is available not only for Vexpress boards, but also Samsung Origen and Arndale boards, as well as Texas Instruments Pandabord and Beagleboard. Here are the highlights of this release: LAVA First prototype production run of LAVA Lmp completed, tested functional. Beaglebone Black is now running in LAVA. TC2s is now running […]

BeagleBone Black vs Raspberry Pi – Features and Price Comparison

The Beagleboard community officially announced the BeagleBone Black and its $45 price tag on the 22nd of April. Many blogs and news sites touted it as a Raspberry Pi killer, and R-Pi vs BBB fanboys fights ensued, and many articles with incorrect information or heavily biased were published. There’s however one decent BeagleBone Black vs Raspberry Pi comparison from a robotic point of view, so I’ll build from there with some corrections and additions. I’ll compare both the features and the price differential between the Raspberry Pi Model B and BeagleBone Black boards depending on use cases. BeagleBone Black vs Raspberry Pi – The Features BeagleBone Black Raspberry Pi Model B Comment Processor TI Sitara AM3359AZCZ100 Cortex A8 @ 1GHz(will be changed to AM3358BZCZ100 in future versions) Broadcom BCM2835 ARM11 @ 700 MHz (Overclockable to 1GHz) Even thoughboth processors can run at the same frequency (after overclocking the R-Pi), but […]
