Hi Henk, CAPE-2 is the second satellite from the Cajun Advanced Picosatellite Experiment. We are planning to fly a digipeater, text to speech module, voice repeater and VHF and UHF radios. I am currently developing software to distribute to you guys later this year that will copy our telemetry and have it automatically sent back to us.
We have already implemented the ability to send APRS emails, but would now like to do the same with twitter.
