Download and cut the acrylic template files using a laser cutter
Put together part A, B,C, D, E, F as shown in the picture using acrylic glue
Glue part F(wheel), G(blue), H(transparent) together in the sequence as shown in the picture using acrylic glue.
make sure part G and H are aligned and being placed in the middle of each circle on part F.
repeat this step 4 times to all five circles of part F.
glue the magnets inside the hole on the wheel, repeat this step 4 times to all five holes on part F.
Using alligator clips, build and test the circuit as show in the diagram.
transfer the circuit on the finished container using conductive tape. It might be helpful to draw out the traces on using marker before placing the tape.
insert the wood dowel through the holes to put the container part and wheel part together as shown in the picture, and then use the part I (4 white acrylic rings) to hold things in place.
place a layer of paper inside the box to prevent the coin from touching the circuit.
