Arduino Sensor Pod - Mock up

I got all my parts in from eBay finally (well except a 3 volt regulator pack they had to reship). So I soldered up some headers on to a mock up of the layout. I think I may put in the effort and cash to get some custom pcb's for this project. Mainly because this will be a lot of wiring if I don't and a real mess to troubleshoot if there's an issue. I like having the header pins though, makes it easy to swap out parts and move things around.
