Accelerometers will be placed in the in the indent in the top half, with the vibration motors in the bottom half, as close to the fingers as possible to provide the strongest feedback possible.
The circuitboards will be glued in place and a sheet of neoprene will be placed in between the two halves to separate the two circuitboards to prevent any short circuiting, and the two halves glued together using some sort of adhesive.
