This Week
This week was mainly spent coming up with measurements for and modeling the 3D case for our product, see Figure 1. Part of this involved modeling the Adafruit 412 solenoids, see Figure 2, in solidworks, since models could not be found online. The length of travel of the solenoid was initially a concern, since it is only 4mm and a keyboard’s keys have a travel length of 10mm. However, by positioning the solenoids on the keyboard such that the keys are always depressed by 5mm, the solenoids are able to activate the piano keys with only 4mm of travel. In short, the ability of the Adafruit 412 solenoids to depress the piano keys enough to activate the keys is not a concern.

Next Week
Next week, if the rest of the materials arrive, I will test our solenoid circuitry with Shravya. Otherwise, I will be solely focused on working on implementing the eye tracking software.
