#RaspberryPi parking camera with distance sensor / @Raspberry_Pi

by  •  • 1 Comment

Jeremy Blythe has been busy building a parking sensor/camera with distance warning out of a Raspberry Pi, Sharp distance sensor, 2.2″ LCD screen and a Microsoft Lifecam Cinema camera. He has blogged about it and included all the code necessary to replicate the project. Extra kudos is awarded for using Meccano as the mounting structure! Read all about it here

Dave Akerman creates new lightweight #RaspberryPi balloon payload

by  •  • 5 Comments

Dave, who also has a pre-release camera module, has been busy building the next payload for his Raspberry Pi balloon flights. His previous Pi was given as a gift to Eben Upton of the Foundation just recently and Dave is now using a model A, together with the camera module, to create the payload. The model A has been stripped of the majority of it’s ports (such as the USB, composite video and HDMI) to lower the weight. Read more about it here.

First encoded video from my #RaspberryPi camera module / @Raspberry_Pi

After much messing around with both ffmpeg and avconv, I’ve finally found a combination that works to convert a raw H264 recording from the camera module to something usable. I converted it to an Ogg-format video. That means that it should display below. I haven’t figured out how to convert to MP4 yet, but if you’re using Chrome you shouldn’t have any problems.

You may be wondering why I chose such a dull thing to point the camera at – well, you don’t get trees blowing in the breeze anywhere, ya know!

The call to avconv I used was as follows:

avconv -i sample-video.h264 -b 1500k -vcodec libtheora -acodec libvorbis -ab 160000 -g 30 -s 800×600 out.ogv
