Intro: Mind Control Finger

The problem being presented is that the body often lacks the grip and strength to grapple and attach to stuff as easily, and animals that are more developed often have an extra thumb or finger in order to utilize things to maximum capacity

question: how can I create a extra finger that retracts and moves on its own

STEP 1: Variables

Controlled variables: the wave length frequency and

the level of change between the frequencies of focusing with the frequencies of being unfocused or “zoned out”

Independent variables: headset connected to Arduino that measures the output of neuron waves that are produced.

Dependent variables: the wavelength and volume of waves.

STEP 2: Background Research

Open EEG offers a wealth of hardware schematics,

notes, and free software for building your own EEG system. It’s a great project, but the trouble is that the hardware costs add up quickly, and there isn’t a plug-and-play implementation comparable to the EEG toys.

The Nerosky MindSet is a reasonable deal as well — it’s wireless, supported, and plays nicely with the company’s free developer tools.

I decided to work it out and make a replacement for a mind control project by using one of the old toys that are found in star wars “control the force” toys.

STEP 3: Materials

1- eeg Arduino (found in the mind control “force trainer”

from starwars)

2- control application

3-Small Electric Motor 1.5v to 3v

4-String ( 10 inches +)

5-Custom 3d modelled joints and attachments

7- c sharp

STEP 4: Procedure

1- print out the custom joints and attachments for the

finger

2- connect and assemble the attatchments

3-Put the string through the joints to act as a pulling mechanism

4-Connect and glue the end of the string to the motor

5-Connect the motor to the Arduino and use it as an output for the connection and signal

6- connect the Arduino to the other eeg card, and another to the Bluetooth connected Arduino found on the output hand

7-code the Arduino to be connected to the computer, and for it to display the level of energy and wavelength that is produced.

8-program it to detect large spikes, and if any spike is detected, it sends a signal to the Arduino to activate the code and start the pulling system, and if it notices another spike, it should retract the string and turn off the motor.

STEP 5: Data

The signal is sent from one part and received to be used and create a movement or action

STEP 6: Result

I was able to model and create a concept for a mechanical finger

STEP 7: Conclusion

If I would chance something from this project, I would

add a button that acts as a switch to be able to manually change it using my feet or other hands rather than the brain in order to correct any mistakes done by the program

STEP 8: Application

This research is important because it helps people who are unable to express and use a finger if they needed an extra one, or if they did not have one in the beginning due to unfortunate events.
