We want to prepare few things to community:

1. Full meteo station with extra CO2 sensors.
2. LED RGB display to present CO2 level @ 37c3
3. Challenges connected to LED display - maybe some hacks
4. DIY device that is used on sailboats as AIS (Maritime ship identification system) and GPS. Also if w arrange that we want to present other GDMSS equipment like SART transponders or EPIRB.,
