Hi yes the whole idea of this is that we will substitue the real egg for the monitor one.
I have attached some pictures. The small egg is the smallest egg the I think we might be able to squeeze everything in to and the larger is a Vulture egg. Loads of room for batteries 
The small stack is the Microduino modules all stacked together. The uno is for scale.
1 x Microduino-Core+
1 x Microduino-FT232R
1 x Microduino-nRF24
1 x Microduino-SD
1 x Microduino-10DOF
1 x Microduino-BM
