On the 1st of March we met with some hobbyists from Happylab Wien to present our project CAPTOR and to discuss the technology of our measuring instruments. The interest in the project and our Raptors and Captors was great. There was a lively discussion on the project, the measuring devices and possible suggestions for improvement. The event gave us important input for the CAPTOR construction workshop on April 20. We are looking forward to the CAPTOR building workshop, see you there.
