I have been working with the GPs and EEG sensor. I have also been experimenting with the Solar Panels and judging how many Volts etc it needs during each moment. Working on sleeping the arduino has been difficult but I have successfully hacked together the EEG and GPS shield. It is not working indoors but as my project is outdoors this should not matter!
Above are photographs documenting my GPS test with Solar Panel. The Tests prove that the Solar Panel can successfully provide enough electricity to the gPS without a lithium battery. Hacking out the EEG has proved more difficult but I am working on removing them form their casing!
Above is proof of GPs data gathering into CSV. I have also successfully gathered EEG data into CSV and am working on passing these both simultaneously through python into Rhino!
