Since we last reported about The Great Internet Migratory Box of Electronic Junk, several of these boxes have begun circulating in different areas of the world. Team Hack-a-Day launched three themselves. Robots.net decided that there was a need for a specialized box just for those who hack robots, and have launched their own.
NASA just completed the first deep-space test of what could one day become the interplanetary internet. Images of Mars and its moon Phobos were sent back and forth between computers on Earth and NASA’s Epoxi spacecraft. Instead of TCP/IP a new protocol, named “Disruption/Delay Tolerant Networking” (DTN) was used. Information is only sent once with DTN, and stored at each node until another node is available to receive the information. To prevent hackers from interfering with the network, information that is transmitted over DTN is encrypted. The team at NASA is hoping to get the protocol accepted by the international community and setup a permanent node at the International Space Station next year.

Wondering what we did with our web server on a business card project from last week? It’s powering a giant LED graffiti wall. Animations can be user-submitted using the online designer. You can watch a live feed of user animations as well. The online interface runs on the Google App Engine for maximum scalability and resilience.
In today’s How-to we cover all the ins and outs of building your own networked graffiti wall. Continue reading “How-to: Networked Graffiti Wall”
