01/20/09	Elphel line of cameras will not be influenced by the future discontinuation of Axis ETRAX FS processors. Recently Axis Communications announced that their ETRAX line of processors is going to be discontinued in 2010. That fact will not influence the line of Elphel cameras - we are already working on the next camera system board design that will be mechanically and electrically compatible with the current 10353 boards, use most of the same software and FPGA code but have different CPU. Current 10369 boards are already designed in anticipation of that future CPU upgrade and incorporate USB 2.0 hub not supported by the Axis ETRAX FS. Of course that new system board will also use the next generation of the Xilinx Spartan FPGA, have more and faster memory, faster network connection. And there will be significant overlap in the manufacturing and support of the current model 353 cameras and the next generation ones.
01/18/09	Elphel is now offering Asus EEE Box computer with preinstalled development environment for Elphel model 353 series cameras. Installation is based on Kubuntu 8.10 and includes all the needed packages and applications, you'll be able to start customizing your camera code even if you are new to GNU/Linux. The project code is managed with KDevelop IDE (see screenshot), we also include FPGA development software Xilinx WebPack (requires registration with Xilinx) that allows you to run your code in the camera FPGA Icarus Verilog Simulator and GTKWave waveform viewer And of course there are viewers that have all the needed patches applied so the can handle high resolution video recorded with Elphel cameras.
07/26/08	All software and FPGA code code developed at Elphel is relicensed under GNU GPL Version 3 that better suits application of Free software to the hardware products.

07/11/08	Meet Elphel team members at LinuxTag 2006 (May 3-6, 2006) in Wiesbaden, Germany. We will show you our cameras in booth 117 update: Elphel booth at LinuxTag 2006 - view from the model 333 cameras
07/11/08	Elphel has moved to a new office. Here is a live view of Salt Lake City from one of the model 333 cameras on the roof above the office. Another camera looks North-West from the same point.
07/11/08	Preliminary documentation for the Elphel models 353/353 cameras hardware is now available 353/363 cameras use software based on Linux kernel 2.6 (currently - 2.6.15). There will be more changes in software as we used different web server (lighttpd) and included PHP (as fastCGI application). More information and software will follow, you may find code here: * elphel353 software package @ Sourceforge * CVS @ Sourceforge
07/11/08	Elphel Model 353 is FCC part 15 compliant - testing of the Elphel model 353 camera performed by Communication Certification Laboratory (CCL) has found that it does meet FCC part 15 requirements for class A Verification. Tests were performed to measure radiated and conducted electromagnetic interference generated by the cameras when operated with specified settings.
