Cheap Accessories for Raspberry Pi – Camera, microSD adapter, Debug Board, Heatsink and Enclosure

The Raspberry Pi just a great low cost ARM Linux board that costs $25 (Model A) to $35 (Model B), but once you start to add accessories the total cost of ownership may creep up quickly, and in some cases accessories may be more expensive than the board itself. I’ll list some alternative accessories that can be purchased online for a fraction of the cost of the more famous one. $18 Raspberry Pi Camera The official Raspberry Pi camera costs $25 + shipping and tax, but you can get a similar 5MP CSI camera for just $18.13 including shipping on Banggood.com. This camera clone should be software compatible with the original one according to the listed features: Plugs directly into the CSI connector on the Raspberry Pi 5MP resolution image (2592 x 1944), or 1080p HD video recording at 30fps 5MP (2592 x 1944 pixels) Omnivision 5647 sensor in a […]

Embedded Linux Conference Europe 2013 Schedule – Build Systems, Security, Device Tree, Debugging & Profiling Techniques, and More

Embedded Linux Conference Europe 2013 will conveniently start right after LinuxCon 2013, last 2 days (October 23-24), and take place at the same location: the Edinburgh International Conference Center, Edinburgh, United Kingdom. The Linux Foundation has published the schedule for the conference, so I’ll make my own virtual schedule with sessions that I find particularly interesting. Thursday – 24th of October 9:30 – 10:10 – Timeline For Embedded Linux by Chris Simmonds, Consultant, 2net Limited Today, Linux is woven into the fabric of our technology. Things such as printers, routers, TVs and phones all have their own “Inner Penguin”. Yet it was never originally intended to be used beyond desktop and server PCs. A lot of things had to happen before Linux could break out of the PC environment and make its way in the world as a jobbing jack-of-all-trades. Since the early beginnings of embedded Linux in the late 1990’s many people have contributed […]
