Video recordings from the 2nd Open Source Cubesat Workshop are now available on YouTube, thanks to Libre Space Foundation. This includes my presentation about the Copenhagen Suborbitals Nexø II rocket cameras and video transmitter, which you can see below.
Avionics in the Copenhagen Suborbitals Nexø II rocket
Peter Scott (OZ2ABA) and myself gave a presentation at the 2018 AMSAT UK colloquium about the avionics in the Copenhagen Suborbitals Nexø II rocket. This included the radios and the DVB-S2 video transmitter used on the rocket. A video recording of the presentation is now available on the AMSAT UK YouTube channel, thanks to BATC.
Nexø II debriefing: Onboard cameras & the video transmitter
Here is a video recording of my presentation of the onboard cameras and the video transmitter, given at the Copenhagen Suborbitals Nexø II debriefing event.

In my previous post, you could watch an edited video from the Nexø II onboard cameras. I have now also made the raw footage available on my YouTube channel.
