These steps apply only to the talking computer prop. For the total conversion beam, you can go back.
Install Handle
Place the half of the melon over the top of the handle.
Insert the various cables through the large hole in the half of the blaster.
The trigger button on the handle and the speaker grille in the melon-half should point the same way — this is the front of the prop.
Install PCB Mount
Place the PCB mount over the mounting holes of the melon and handle. Feather’s USB port should point away from the speaker grille.
While holding in place, insert and fasten 3x M3x12mm long screws to secure the PCB mount.
The screws secure the PCB mount, melon and handle together.
Note: there is a fourth mounting hole, but it’s obscured by the Feather PCB so we’ll just skip it. Three screws should suffice, or you can use a few small dabs of glue to help reinforce the body-to-handle connection.
Install Speaker
Peel the adhesive tab and press the speaker face-down into the cavity inside this half of the melon.
Secure Slide Switch Holder
Place the slide switch holder into the melon half. Line up the mounting holes. Insert and fasten 2x M3 x 6mm screws. Use matching hex nuts to secure the slide switch holder to the melon half.
Install LED
Insert the 10mm LED through the hole in the top half of the melon part. It might not press-fit firmly, but the next part will help hold it in place…
Secure Key Plate
Place the key plate over the top half of the melon. Line up the mounting holes. Use 4x M3 x 6mm long screws to secure the key plate to the top melon half.
Test Circuit
Use the slide switch to power on the circuit. Use the push button and key switches to test the circuit.
