MyCroft, henc why I'm not opening ours. I'm looking at doing this as part of a college project in which case the lucky unit would be removed from service or a spefic unit purchased for that reason. I also don't need more than the general space available until I'm well down the development cycle.
I'm not talking about "modding" it to the extent of interfering with its electrical or mechanical components, just using the extra space available if any. If there is none and i need to get onto medtronic and ask for a specialty unit to be produced. But i want to see how feasible the concept is before I go down that route.
If anyone is interested I'll chat via PM but until i can decide on the idea and set up a patient if applicable I don't want to broadcast it.
