1Build attachment of paddle to motor
First, saw off the handle of the cereal dispenser so that there is a flat base.
Laser cut a circle out of wood (I did 80mm, but this was slightly too larger) and mark the centre of the circle.
Drill two holes into the servo attachment to fit two bolts.
Mark the two drilled hole position on the circular wood and drill two holes the same place so that a bolt can be attached through the servo attachment and the circular wooden piece.
Bolt the servo attachment and piece of wood together.
Using a hot glue gun, glue the paddle wheel axis on the opposite side of the servo attachment in the centre.

3Make base supports for feeder
One of the more simple parts of the build.
Cut to longer lengths of wood and shorter lengths of wood and mark the middle of the longer wood sections.
Using the four shorter lengths of wood, create a slot for the back on the feeder to slot into. This can be achieved by measuring the diameter of the back piece and securing the pieces of wood with a gap of the measured diameter between. The gap should lie at the marked middle of the longer piece of wood.
Secure the smaller pieces of wood to the longer piece with screws.

4Build 'weighing scale' (load cell attachment)
Cut two identical piece of wood and cut out a rectangle out of one pieces. Using a laser cutter would be ideal here.
Attach three pieces of wood to cover the perimeter ,expect the far end (other side to the strain gauge) of the base with screws.
In line with the cut out, attach the strain gauge to the base with a pacer with a bolt.
Attach the small cut out piece of wood to the top side of the strain gauge to create the weighing platform.
Finally, before attaching the 'lid', ensure that the wires of strain gauge reach the back of the base. If they do not, you will want to extend the wires or change them for longer wires. I used crimped spade connections to lengthen mine.
Now screw the lid on top so that the weighing platform is not caught on the lid and can move freely to allow a weight to be measured.
