Assistive Technology Project Update - 8/9/22


 This is an AbleNet Jelly Bean switch. This switch costs around $75. It contains:

- 3.5mm mono audio jack and cable—about 6 feet total (measured). ($1.59)

- 1 3/8 inch activation surface. Note that this surface has a piece of rubber padding on the back surface. (Est. few cents to $1)

- 3.5-ounce activating microswitch. (19¢ per piece [pack of 10 is $1.88])

- Misc. category: Spring, casing, and two screws. (In total cost up to (being generous) $3)

This switch should cost no more than $10 to produce one—not to mention partial-mass production. 

------------------------------------------------------------------

The requirements for designing a switch (✓ indicates that the item/requirement has been attained) :

- An activation surface of no less than 1.72 inches squared

- A cord length of 6ft. ✓

- A activation weight of around 3-4 ounces. ✓

- Low-cost yet high-quality and reliable. 

- Auditory and tactile feedback.

- Easy to produce

Assistive Technology Project Update - 7/21/22

 After considering the options, here are the "feasibility scores" of the following projects: Each project will start with 10 points and 0-5 points will be deducted for every major difficulty regarding the making of the project.   1) An eye-track software to paper drawing tool that would take eye movement input and translate that to coordinates for a writing untensil on paper. Requires:  - Knowledge of eye-tracking software and how to grab information from software. -5 - Coding knowledge (of which I have some) -0.5 - Building/assembly and electronics -0 Total: 4.5 2) A toy car with a gas pedal that would be adaptable to more accessible (AT) inputs. Requires:  - Circuitry knowledge/electrical engineering (I have moderate to advanced knowledge)  - Specifically variable resistance (for variable speed and adaptability will be a minor difficulty) -2 Total: 8 3) A block stacker that is adaptable to common AT inputs. Requires: - Designing a mechanism to (what I wou...

Assistive Technology Project Update - 1/8/23

 Big news: The first working prototype has been made. This was achieved before the new year, but due to workload, updates had not been posted.  What happens next? I am still working on sourcing the best-fit microswitches and wires. There will be some more prototypes before more are produced.  [Attached: video of mechanism and switch].

Assistive Technology Project Update - 11/24/22

The first round of designs is finished and has been queued for production.  The 3D printing slicer (a program that makes the 3D printer path) estimates the total cost of one switch to be around $1.50.  Prototype printing is expected to take place in December. Electronic testing and prototyping are expected from Dec. to early 2023. (PrusaSlicer program. Less than 50 cents for the intermediate spring body.)
