Leap Motion Lets You Control Your Computer With Finger Gestures

Leap Motion is a tiny USB device, about the size of a thumb drive, that let’s you control your computer with hands and fingers (and even pencils) gestures in three dimensions using motion sensing and motion control technology. The company claims that Leap technology is 200 times more accurate than existing solutions with an accuracy up to 0.01 millimeter (which seems over the top). To use the LEAP, simply plug it into a USB port, install Leap Motion software, calibrate the device and you’re ready to control your PC a la minority report. This technology will probably not displace the mouse and keyboard, as your arms would get very tired after a while, but there are some good use cases: Stylus emulation and 3D images creation. Gaming. 3D modeling software interaction. Sign a document digitally with a pen. User interaction in Windows 7/8 or Mac OS X: Clicking, grabbing, scrolling, […]

Droid Stick KVD-13 Another Low Cost Android mini-PC

Following the steps of the $74 Android 4.0 mini PC (MK802), a couple more ARM based mini PCs have shown up, including Shenzhen Kimdecent Technology Droid Stick KVD-13 powered by a Renesas processor based on Cortex A9 with a PowerVR SGX530 GPU (possibly Renesas NEC EV2 processor), featuring 512 MB RAM, 4GB Flash and running Android 2.3. The good thing with this mini PC is that the HDMI connector is of the right gender: male. No offense to HDMI female connectors ;), but for this type of device, it’s just neat to plug it directly into the TV/monitor HDMI connector. Here are the device specifications: CPU Renesas Cortex-A9 Dual Core Processor @ 1GHz with PowerVG SGX530 GPU System Memory 512MB DDR3 Storage 4GB NAND Flash microSD card Connectivity WiFi 802.11b/g/n USB Ports 1x USB 2.0 Host 1x mini USB (for power) Video Output 1x HDMI 1.4 (Up to 1080p) Video Codecs […]

IAR Systems I-jet Hardware Debugging Probe Is Now Available

IAR Systems has announced the availability of I-jet, a new in-circuit debugging probe that can be used in conjunction with Embedded Workbench for ARM, IAR C/C++ compiler and debugger tool suite. I-jet provides download speeds of up to 1 MB per second, JTAG and Serial Wire Debug (SWD) clocking at up to 32 MHz (no limit on the MCU clock speed), and Serial Wire Output (SWO) frequencies of up to 60 MHz. I-jet probe is powered by USB and can also power the target board (Up to 400mA) and measure the power consumption accuratly (200 uA @ 200khz). The probe is plug-and-play, and supports automatic core recognition, and direct download into the flash memory. I-Jet supports ARM7, ARM9, ARM11, ARM Cortex-M, ARM Cortex-R4, and ARM Cortex-A5/A8/A9 cores. Serial Wire Viewer (SWV), Embedded Trace Buffer (ETB) and JTAG adaptive clocking are supported and all JTAG signals can be monitored. The probe […]

Linux 3.4 Release

Linus Torvalds has just announced the release of Linux Kernel 3.4 on the 20th of May: I just pushed out the 3.4 release. Nothing really exciting happened since -rc7, although the workaround for a linker bug on x86 is larger than I’d have liked at this stage, and sticks out like a sore thumb in the diffstat. That said, it’s not like even that patch was really all that scary. In fact, I think the 3.4 release cycle as a whole has been fairly calm. Sure, I always wish for the -rc’s to calm down more quickly than they ever seem to do, but I think on the whole we didn’t have any big disruptive events, which is just how I like it. Let’s hope the 3.5 merge window is a calm one too. Linus Linux 3.3 merged Android drivers to mainline, added further improvements to btrfs and ext-4 file […]

25 USD Hacker Friendly Electric Imp “WiFi-ises” Your Coffee Machine

Electric Imp is a device in an SD card form factor that aims at providing Wi-Fi connectivity to household appliances at low cost and bringing the Internet of Things (IoT) closer to reality. The Imp will also connect to a Cloud service handled by the company (which is also called Electric Imp). The device Wi-Fi connection can easily be configured using an iOS or Android smartphone thanks to BlinkUp, a patent-pending scheme supporting WEP, WPA and WPA2 encryption schemes as well as WPS setup. Electric Imp developers expect this device to save resources (e.g. electricity) by taking into account environmental conditions (e.g. occupancy, temperature..), improve security & safety and overall provide better monitoring and control of devices. For example, this could enable support services to remotely diagnose a device, and provide timely customer support. Here are the Electric Imp hardware specifications: ST Micro STM32 Cortex M3 MCU 802.11b/g/n WiFi 6 […]

Raspberry Pi Camera Module Up and Running. Retail Version Coming Soon

The Raspberry Pi foundation is working on a camera module for the Raspberry Pi board and today they showed the very first picture taken with the “PiCam” module. The picture below has been taken with a camera module connected via the MIPI CSI-2 interface of the Raspberry Pi. On another subject, if you look closely at the top left of the picture, you can see the Raspberry Pi foundation (and probably Broadcom) uses Synopsys MetaWare Debugger (and Compiler?) to work on the software and fix bugs. Maybe more on that later… The camera module used supports up to 14 Mpixel resolution, but the final module will most probably have a 5MP resolution in order to make it cheaper. The mechanical design is not complete and the foundation does not have a price for the camera module yet. You can see what the 14MP camera module looks like (it’s basically a […]

Getting Ubuntu armel/armhf Rootfs in Ubuntu 12.04

I’ve recently upgraded to Ubuntu 12.04 and this is a great operating system. However, if you do some arm development and expect to be able to install cross libraries (armel/armhf) or easily generate an arm rootfs using the tools you’ve been used to, you’ll be disappointed. In Ubuntu 11.10 (Oneiric), I used xapt and dpkg-cross to retrieve armel libraries, but it’s broken for Ubuntu 12.04, at least on my system. I’ve been told to switch to multiarch because this will be how it’s done from now on. But I soon discovered this is work in progress as quite a few packages are not multiarched yet including python. Ubuntu developers also decided to remove rootstock (which makes sense since xapt/dpkg-cross will be deprecated), so if you want to generate a rootfs the “gool ol’” way (which won’t be supported much longer), you’d have to install an Oneric chroot to run rootstock, […]
