Measure and cut a piece of balsa wood to
reach from the end of the embroidery hoop
to the wall of your pachinko machine.
Sand the edges down. You want the
ramp to be as smooth as possible!
Glue the ramp in place.
Make a mark where you want to attach
your launcher. Ours is about two inches
from the bottom edge of the game board.
Drill a hole where you made the mark
using the 1/4″ bit.
Glue the bottom, left, and right sides of
your tray to the board.
Glue the front of your tray on. Make sure
your hand can fit in! This is where you will
be storing your pachinko balls.
Now grab the launcher that you made in
part one of this project. Place the dowel into
the top launcher hole and mark where the
bottom hole lines up
Drill a 1/4″ hole into the launcher where
you made the mark in step 4.
Use the nut and washers to secure
the launcher to your game board. It doesn’t
have to be super tight!
Use the hack saw to cut off any part of
the launcher that hangs below the bottom of
the game and sand it down.
Measure and cut four pieces of wood
that are the same size as your magnets.
Mark three inches from the top and
bottom of your playing field on the left and
right side of your game.
Glue magnets to four of the pieces of
Glue the four pieces of wood to the four
spots that you marked in step 7.
Carefully drill a hole near the bottom
right of your plexiglass. This is where you
will insert the Pachinko balls to launch
Place the other four magnets on top of
the four that are glued to the game board.
Now add hot glue to the back of the four
magnets that you just placed.
Quickly lay the plexiglass on top of the
hot glue that you just dispensed. This will
attach the four magnets to the plexiglass.
Glue a small, wooden divider to your
tray so that you have a space to store your
pachinko balls and a space that is large
enough for your electronic components.
Use the 5/8″ drill bit at an angle to
“tune” the five ball holes on the back of the
board. Make them slant downwards so that
the pachinko balls can easily roll out.
Drill some holes through the back of
the electronic components side of your tray.
This is where the wires will go.
Now drill a hole through the back of
the pachinko ball section of your tray.
Draw paths from the five ball holes
to the pachinko ball hole that you made in
Glue a small piece of wood at an angle
so that the pachinko balls will roll towards
the pachinko ball hole.
Make channels with the plastic
canvas from each and every ball hole to the
ramp. Glue them down. Make sure to make
the arcs large enough for the pachinko balls
to freely fall!
Use one more piece plastic canvas to
cover the ramp. Now it’s time to add
This is the part of the project where you can really let your creativity shine! We
will provide the circuit diagram and code for our game design, but there are
countless possibilties when it comes to enhancing your pachinko machine.
For the circuit, wire up your breadboard and Arduino according to the diagram on
the following page. You will most likely have to extend the pins on certain
components (like the button and the LED) using solder and hookup wire. For more
details on each component and on the diagram, watch the video for this project
For the Arduino code, please visit makercamp.com where you can copy it and then
paste it into the Arduino IDE:
