Raspberry Pi z3r0!

Prototyping
08/12/2014 at 02:40 • 0 commentsWhile I wait for my sample orders to arrive. I am going to get a patchwork system running on my RasPi. I need to get rotating mac addresses, as well as some sort of smart traffic monitor that will only start an exit node if there is a certain threshold of traffic already passing by. This requires promiscuous mode to be enabled, and I don't know how much that is going to effect power requirements.
Also, I need to start looking at passive ways of collecting power that are super cheap. My hope was to be able to run a node with a watch battery, but I see now that this is infeasible, especially to be a useful exit node. The power requirements are going to be much higher. The more battery though, the higher the cost. Arrrggghhh.
Here is a good article I found comparing power requirements for different wireless standards.

It's a bit dated, but It really put things into perspective.
