First contact with the Cubieboard

I got myself a Cubieboard some months ago, not because I needed one by because I had the opportunity to join a group purchase organized by some friends back then. I wasn’t looking for a new board, however, the Cubieboard looked interesting because of the onboard SATA connector. Plus the analog audio input / output on the board may also prove useful for SDR and digital voice experiments.

The Funcube Dongle Pro and Pro+ on the Raspberry Pi

Although I have had a Raspberry Pi rev B for several weeks now, it wasn’t until last night that I got a chance to try it out. Since several people have reported failed attempts at getting the Funcube Dongle Pro and Pro+ play nicely with the Raspberry Pi, I decided to take it as far as I could in those few hours. The result is this very brief tech note about how to make the Funcube Dongle Pro and Pro+ work on the Raspberry Pi.

Turning the Beaglebone into a high definition IP camera

Few weeks ago I posted some notes about using the Logitech HD Pro Webcam C920 with Gstreamer. I have since ported the setup to the Beaglebone, effectively turning my Beaglebone into a streaming IP camera that can deliver constant bitrate H.264 video at full 1920x1080p30 resolution without breaking a sweat.

Gumstix Overo Water + eCAM32 camera demo

3.2 mega pixel cameraAs promised in my last post, here is a quick demo of the eCAM32 3.2 megapixel camera connected to the Gumstix Overo Water. I am presenting two videos, one showing the setup where the eCAM32 camera board is mounted on top of the Gumstix Overo Water, the other one being a screen cast demonstrating some of the most common settings of the camera. I am using the Tobi expansion board because it has Ethernet interface allowing me to stream H.264 encoded video to a host PC running linux.

The e-CAM32 and e-CAM50 cameras

As I mentioned in my previous post, I had only had limited success with the Caspa VL and Logitech UVC cameras. While both cameras work with the Gumstix, the Caspa seems to take poor images while the Logitech USB camera performance is limited by low USB bandwidth. Therefore, I have decided to try my luck with cameras from e-Con Systems.

Successful flight and a crash landing

Oct 3, 2010 – Danish Space Challenge (DSC) held a Rocket Festival at Borris Sønderland, Denmark, where five rockets built by German and Danish students were launched together with one of DSC’s own rockets. For the first time, the DSC rocket was flying an Arduino Duemilanove based flight computer which was responsible for releasing the parachute. This worked well. The payload in the rocket consisted of the digital video recorder built by yours truly, based on the Gumstix Overo Fire embedded Linux computer that I have been blogging about during the last few weeks, see here.
