The left side of the shell, has the safety switch, and 2x hall effect sensors for magazine size detection. There is an 8pin connector to disconnect it from the other side, makes it easier to work on.
The right side of the shell. You can see all the various bits and pieces. In hindsight i'd have used a nano extension board and put it in the battery bay, would have made hooking everything up easier. The joystick isnt visible as its under the magazine release mechanism, and the voltage/current sensor is mounted flat on the bottom of the battery bay so cant really be seen.
The magazine insertion switch, and jam door switch are the existing switches in the blaster, just re-purposed.
The paint needs finishing and detailing (and stripping in the case of the trigger), but here you can see the screen and joystick. The joystick can be reached by the trigger finger.
