I'm trying a new method to mount the MQ-1 circuit board. I think this will be pretty similar to how the original was done.
I started by using CA glue to secure two thin styrene tubes into the back of the helmet, one on either side of the keyslots. Then I measured and cut a rectangle of black styrene, adding a couple of bends to leave a gap so the circuit board will fit in.
In these pics, the black styrene isn't attached yet. It's held in place by the two thin tubes. Once I paint the outer face red, I'll attach the circuit board, glue the styrene in, and then use some Milliput to cover the tubes.
