The Thought Emporium

Last week we started on the construction of a mini radio telescope with 2 main goals. The first is to design a scalable system so that later projects can be built with larger and larger antennas for imaging the sky and pulling data from far away satellites. The second is to use this prototype to take images of terrestrial frequencies, starting with WIFI.

If you missed last weeks video heres a link so you can get caught up: /youtube/video/o6WHhqDHSQ4

This will be a 3 part series as this project has been one of the more complex and is taking time to sort out all the bugs and kinks. This week we finished assembly and got everything moving and starting working on the radio capturing script. Next week we'll have some actual images and will go through the coding and programs used to run this robot.
