Create One For Yourself
How to Recreate our Product
Cylindrical Door Handle (Amazon)
Golf Cart Umbrella Holder (Amazon)
1" Diameter PVC Pipe (optional, dependent on wheelchair size and desired camera height)
#4-40 Machine Screws
Arduino Super Starter Kit (Amazon)
Bluetooth Module (Amazon)
Pine wood board (size dependent on wheelchair)
4 - 2"x4"x8" pieces of wood
Butcher block oil or wood stain
4 - 2" x 1.5" x 2.75" angle brackets (Home Depot)
16 - wood screws, size dependent on wood board thickness
Linear Slide Leg
Old, large pant made from strong fabric
Linear slide (size dependent on wheelchair)
2 adjustable buckle straps
T shirt or button down
Glue or sewing machine
Lap Desk (option 1)
Cut down pine wood board to be the length and width you desire for your lap and your wheelchair. Ensure you can place the board over your legs.
Sand and treat your wood, utilizing butcher block oil or stain as necessary. Ensure to follow the directions of whatever product you use.
Use the angle brackets and wood screws to attach the 2"x4"x8"pieces of wood to the corners on the bottom of the pine wood board.
The lap desk should now look like a small table with four legs. Ensure the lap desk still fits on the person in the wheelchair.
Linear Slide Leg (option 2)
Find some old, large pants made from a strong fabric.
Cut out pieces of cardboard that can fit around your legs with a 2-3" opening
Cover the cardboard with fabric using glue and/or sewing.
Attach buckles to the leg holders such that you can loosen and tighten the leg holders.
Attach a piece of the hook side of Velcro to the top of both cardboard-fabric pieces
Attach a piece of the loop side of Velcro to each of the slides on the linear slide.
Place the linear slide on top of the cardboard-fabric pieces such that the Velcro sticks together.
Mount the door handle. Depending on what door handle you use, mount based on the instructions provided by the door handle. Ensure to mount the door handle in the center of the pine wood board or linear slide.
Once the door handle is mounted and secured, attach the golf cart umbrella holder using the screws.
If additional height is desired, cut the PVC pipe to size and place it in the umbrella holder.
To ensure that your mount does not move or fall, you can add two supports.
Use an old t shirt with a cut down the center or a button down. Place it on the wheelchair like you would a person, with the wheelchair arms going through the arms of the shirt.
Use scraps from the t shirt or button down to create straps. These can be made with a sewing machine or glue. The robustness of your straps is up to you. You can just use the raw cut fabric, or create a tube with it for a more finished look.
Attach velcro to the shirt on the wheelchair's shoulders and the straps.
Wrap the straps around the mounting area and attach the straps to the back of the wheelchair for more stability.
The straps can also be fastened to the wheelchair arms, depending on personal preference.
3D Printed Parts
Motor Housing (x3): A tall cylinder which houses one of the three motors. A motor is screwed into the elevated platform, with the motor head aligning with the center of the cylinder. The chord is fed through the holes and out of the housing. There are grooves within the upper portion of the cylinder that serve as a track to ensure smooth and stable movement of the motor caps.
Motor Cap (x3): A shorter cylinder filled with large holes. The cap is screwed onto the motor adapter such that it aligns with the motor housing. The two ridges on the sides of the cap align with those of the motor cylinder such that the cap can run along the housing's track.
Gimbal base (x1): A piece that holds the bottom motor housing using screws along both flat edges of the design. Used to connect the gimbal body to the gimbal attachment/adapter piece.
Primary gimbal arm (x1): Piece that screws into the bottom motor cap such that it and all attached pieces can turn. A second motor housing is added to the designated location.
Secondary gimbal arm (x1): Piece that screws into the second motor cap such that it and all attached pieces can turn. A third motor housing is added to the designated location.
Tertiary gimbal arm (x1): Piece that screws into the third motor cap such that it and all attached pieces can turn. Instead of a motor cap-attachment piece, a flat edge is used to mount to mount the chosen camera.
Gimbal Adapter (x1): Piece that uses screws to connect the bottom motor housing to the PVC pipe.
Putting Together the Arduino
First, you need to connect the Bluetooth HM-10 module to the Arduino.
Connect the VCC to the 3.3 V port.
Connect the GND to one of the GND ports of the Arduino.
Connect the TX to port 2.
Connect the RX to port 3.
Next, you need to connect one of the motors to the Arduino. (Later this year we will add on to how you connect the other motors using a breadboard.)
Connect the brown cable to GND on the Arduino.
Connect the red cable to the 5V port.
Connect the orange cable to port 10.
Then, connect the Arduino to a battery so that it stays powered, and you will see the Bluetooth module flashing. This means the module is looking for a connection. Go to "How to Use the App" to see how to connect to this module.
