In order to recreate our project you need the following things:
For the mitten:
- 2 plastic gloves
- 2 regular cotton (or similar) gloves
- Solid foam
- Wide ribbon (~30mm)
- Thin ribbon (~5-10mm)
- Thread and needle
- A wrist band/arm wallet (for storing the electronics)
Electronics:
- 2 Arduino Nano
- 2 nRF24L01+ (RF-module)
- 2 DC Motors
- 2 DC Motor Controllers MC33887
- 2 Lithium-ion Batteries
Making the mitten:
Cut some foam into smaller pieces. Fill the plastic gloves with your pieces of foam until satisfied. Seal the opening with some tape. Make a soft button (two L-formed pieces of conductive fabric with thin, pierced foam in between). Cover the plastic glove together with the soft button inside of a regular glove. Pull out the wires from the button. Sew one ribbon on each finger of the glove. Find a spot where the ribbons should meet and sew them together Attach the thinner ribbon to the larger ribbons (we used a safety pin)
The wrist band:
If the wrist band is meant for the upper arm - shorten it to fit the wrist. Make a container for the motor out of a hard material - for example circuit board. The container should be as long as the lid of the wrist band so that the motor is kept straight. Make an attachment for the motor container in the lid of the pocket. We used velcro. Make a hole where the thinner ribbon will run from the glove to the motor. Make sure that the hole is placed so that the motor container does not slip out of it.
Technology:
Upload the codes to the Arduinos. Solder the Arduino, RF module, MC33887 and battery input to a circuit board. Connect all the pins to the correct pins. Solder the DC motor to the MC33887. Use some hot glue to cover some possible gaps.
Assemblage:
Put all of the electronics inside of the wrist band. Solder the wires from the soft button to the circuit board. Hot glue the string from the hand onto the DC motor. Connect the battery. Enjoy!
