If you have a Raspberry Pi mini PC handy and enjoying making electronic projects you might be interested in creating your very own Raspberry Pi HDTV transmitter.
Aexandru Csete from the OZ9AEC website has published details and full instructions this month on how you can create your very own HDTV transmitter using a Raspberry Pi equipped with a RaspiCam camera module.
Once setup as instructed the system effectively transforms the Raspberry Pi into a live HDTV transmitter that can be made small enough to be carried by a medium sized drone if required or in this case the HEAT 2X rocket. Csete explains :
“The first thing to do is to ensure that you have your Raspberry Pi up and running with an up to date Raspbian image and the RaspiCam. You can use this tutorial on the Raspberry Pi website. You should definitely get acquiantened with the raspivid application that is used to capture H.264 encoded video with the camera module. It is a great tool and you will also find it useful for other tasks.
The setup can be made small enough to be carried by a medium size drone and the range can be increased using power amplifiers. If you do that be sure to comply with the radio regulations applicable in your country. In particular, transmitting with significant power in the UHF TV bands will most likely get you into trouble. Your best bet is to get a ham radio license and use the 23 cm band.”
