Just thought i'd show you what I did when I had a spare A4 Fly, DM12 board & some eyes doing nothing when boredom kicked-in.
Little bit of trimming to the top & bottom edges of the board so it fits;
small piece of plastic glued to the frames edge and to the board;
Trimmed down one of the clear frame buttons to use as the on/off
Extended the eye wires and bored out the bodies eye holes a little
Drilled hole into battery chamber to route the eye wires
Video of eyes working
Finished item
Happy Days
