Insert screw in standoff, place on mount hole, using small force, wiggle it while he not place. Remove the screw and press it all the way in with something flat. Place all standoffs.
Cut off small keys from square side of sockets. Place all sockets, square half (where we cut keys) must be on right side. Press them in all the way in with something flat.
Bend top parts of the sockets left contacts to the borders of hole. Place diodes, cathode (black) is point to up side. Cut off the excess part, solder to the two resulting points on the socket. Form rows from other side of diode wires. Cut off the excess parts. Solder them.
Lift up the right half of the sockets. Bend contacts, using wires make the columns. Common length of wire, between sockets is 15mm. Thumb keys are shifted, length of the wires are higher, measure it. Strip 2 mm of insulation from each side.
Bottom right pin unused in 36 key version.
Using scheme, measure wires, cut them and solder on controller.
Place controller. Route wires under rows/columns where it possible.
Place power slider and reset switch, solder. Place battery, solder and isolate contacts.
Place the magnets. Tighten the screws. Stick on the bumpons.
