The antenna (which is a little too big for a balloon), the router and some laptops for testing.
Work on the first stage in getting a site to the space have already started.
¿The objective? Run the site for a full month in a highly populated area from a balloon.
For those interested in the tech, we have an oversized antenna and a router with openWRT running olsrd. Also two laptops running olsrd create a small mesh.
