It’s alive, It’s moving, it’s alive, it’s alive, IT’S ALIVE!

Hit off Halloween with a classic, inspired by Mary Shelly’s creature, Frank_One is a fun and interactive project for this occasion. Much like the game Operation, the creature is lying on an operating table where a few of its organs and some elements in the table enable interactions that might surprise you! The more you tweak with the creature, it’s life starts depleting, until there is no more light left in his life bar.

Step 1: Draw or Download Frank_one´s Parts

You can find the drawing of this model in the following dwg. file. It has been arranged to be cut in 3 a4 MMA boards.

Step 2: Laser Cut Frank_one

For this project he have used A4 3mm (MMA) boards in the following colors :

Black, white and green. To achieve the red and metal color in the heart and bone without utilizing more boards, we have used spray paint.

Step 3: Frank_one Assemble

Utilizing MMA glue, build the bead and individual parts of the body. Such as : The abdomen, pants, feet, and head. This will make the assembly easier with the components.

Step 4: Weldging the Circuit Board Following the Circuit Diagram

Utilizing the circuit diagram we have provided, weld the components into the board. It should look like the image.

Step 5: Assemble Frank_one Fully

Time to assemble ! now you have become the creatures creator! Be very vigilant, bringing Frank_one to life is no easy process. We recommend starting from the bottom-up. Starting with the 10 segment led bar, potentiometer and photoresistor. The heart buttons is where it gets tricky, be sure to stabilize the columns that will connect the buttons with the red heart before blueing the abdomen to the bed. For the servo we have glued an axis that will be later blued to the back of Frank's head (as shown in the photograph).
