This is the working prototype minus the shroud. The four buttons are off the back of a 1000D I use for parts. Other than locating the buttons on the base of the battery grip the bottom corner is the only unobstructed and convenient location. Not by design, two are flush, while the runtime buttons are protruding - easier to find in the dark.
The OLED is happily printing out all kinds of useful data to convince me everything is working just fine. Can't be seen in the image, its located at the battery grip opening.
There are few things that will need redesign. I will never use pico-ezmate connectors for this type of work again, and will revert to surface mounting molex pin connectors top and bottom to save space. The board needs to be 2oz and not the 1oz OHS Park proto board.
The logic board needs to be more accessible, a USB cable will do for now until the board is given a layout overhaul.
Aside from all that, it works very well. Now to rewrite the TEC control code and make it a little smarter. If anything, the new code is the most satifying outcome.
As you can see the camera didn't get a clean before its photo debut
The grip cover got in the way and has been removed.
