Wysips Transparent solar charger built into displays

Wysips, a company based in the south of France, developed a thin transparent photovoltaic film that can be used to charge smartphones, e-book, tablet and even laptop. They were at CTIA 2011 and were interview by laptopmag. Their transparent photovoltaic strip is 100 micrometer thick and can be used with touchscreen and 3D displays. It can provide 250mW for smartphone by continuously charging the device (6 hours of outdoor light) and possibly removing the need for charger. The cost for smartphones would be 1 USD, which could potentially be offset by a smaller battery. They are currently working with handset manufacturer and expect products using their technology to hit the market within 12 months. The next version due in 2012 should provide enough power for 30 minutes of talk time after one hour of charging.

Texas Instruments eZ430-Chronos Wireless Watch Unboxing

I’ve just received the eZ430-Chronos development tool I ordered last week (after 2 working days) by Fedex. Today, I’ll just post some pictures of the kit and provide some descriptions. There is a woman jogging on the box because you can actually buy a chest strap to monitor your speed, heart beat and calories consumption. If you would like to purchase one (49 Euros), it is available at http://www.bm-innovations.com/index.php/shop_products.html. Apparently there are only 868MHz (EU) and 915MHz (USA) versions, and they do not sell the strap for the 433MHz (international) version as I have. The watch is normally turned off the first time you open the box, it’s just turned on on the picture because I used it before taking the pictures. The content of the box includes: eZ430-Chronos wireless watch eZ430 USB programming and debugging interface (Bottom left) CC1111 USB RF access point (Bottom right on top of the […]

Cross compiling Berkeley DB for ARM and MIPS

Following my blog entry about Databases for Linux Embedded Systems, here are the instructions to cross-compile Oracle Berkeley DB. First download the source code of the latest version of Berkeley DB (version 11gR2 – 11.2.5.1.25). You’ll need to register on Oracle website first on the download page http://www.oracle.com/technetwork/database/berkeleydb/downloads/index.html to download http://download.oracle.com/otn/berkeley-db/db-5.1.25.tar.gz (with AES encryption) or http://download.oracle.com/otn/berkeley-db/db-5.1.25.NC.tar.gz (if you don’t need encryption). Extract the source code: tar xzvf ../Downloads/db-5.1.25.tar.gz Configure and build the source code. I’ll use mipsel-linux-gcc, but any other cross-compiler could be used. cd db-5.1.25/build_unix ../dist/configure –host=mipsel-linux CC=mipsel-linux-gcc RANLIB=mipsel-linux-ranlib STRIP=mipsel-linux-strip AR=mipsel-linux-ar –prefix=/home/jaufranc/edev/lib/db-11g make make install The full berkeley DB package is 79MB: jaufranc@CNX-TOWER:~/edev/lib/db-11g$ du –max-depth=1 -h 6.6M ./lib 308K ./bin 72M ./docs 176K ./include 79M . However, you won’t need the include and docs directory in your embedded target. So you do not need to copy those. You may or may need the utilities in the bin file. The […]

Netgem’s IPTV 2.0 Home Cloud SDK

Netgem announced the release of its “Home Cloud” SDK based on IPTV 2.0 open architecture. Here’s an excerpt from the press release: Paris, France March 15 , 2011 Netgem, an IPTV technology leader, has announced it has made its Home Cloud software development kit (SDK) available to application developers, Internet service providers and operator partners.

Qemu Linaro Versatile Express Image on Ubuntu 10.10

I’ve installed qemu-linaro and run an ARM image based on the instructions on https://wiki.linaro.org/PeterMaydell/QemuVersatileExpress. I used Ubuntu 10.10 desktop edition. First, install the Linaro images tools: sudo apt-get install linaro-image-tools Download the Linaro release and versatile hardware pack: wget http://releases.linaro.org/platform/linaro-n/nano/alpha-3/linaro-natty-nano-tar-20110302-0.tar.gz wget http://releases.linaro.org/platform/linaro-n/hwpacks/alpha-3/hwpack_linaro-vexpress_20110302-0_armel_supported.tar.gz You can download another hwpack for omap3, i.mx51, pandaboard, beagleboard, ST U8500, etc.. if needed at http://releases.linaro.org/platform/linaro-n/hwpacks/alpha-3/ Download the source, extract it, then configure, build and install qemu linaro: wget http://launchpad.net/qemu-linaro/trunk/2011.03-1/+download/qemu-linaro-0.14.50-2011.03-1.tar.gz tar xzvf qemu-linaro-0.14.50-2011.03-1.tar.gz cd qemu-linaro-0.14.50-2011.03-1 ./configure –prefix=/usr make sudo make install Make sure the prefix is set to /usr in order to overwrite any previous version of Qemu (It installed qemu linaro in /usr/local/ instead in my case). Failure to do so may generate the following error during linaro-media-create: qemu: fatal: cp15 insn ee1d6f70 Instead of compiling qemu, you can install qemu-linaro with apt-get (this will avoid possible version issues between linaro-media-create and qemu): sudo add-apt-repository ppa:linaro-maintainers/tools […]
