What did you personally accomplish this week on the project? Give files or photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).
I met with Iqui multiple times this week for assistance on designing the mold for the case as well as learning the fabrication process. We made 3 different versions of the case using 3 different materials and fabrication methods.
- Hard Case: 3D printed TPU
- This version was the most rigid out of the three, so it absorbed a lot of the vibration when testing different vibration sequences
- It is the most sturdiest and most reusable material
- Hard flex case: 3D printed soft resin
- Semi hard/semi flexible case
- Also still absorbed a decent amount of the vibrations, making it harder to perceive
- Soft case: liquid silicone that was cured/casted in a separate mold
- The most user friendly/comfortable out of all the cases due to the squishy material
- Also the most fragile since it is so soft, which means it could end up tearing/ripping even during one session
After meeting with Dr. Halilaj with the group, she suggested that we focus the most on the soft case since it is the most wearable out of the three options.
Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
My progress is on schedule since I planned on finishing the case fabrication for the LRA+haptic drivers by the end of this week.
What deliverables do you hope to complete in the next week?
- Resolder the MCU/multiplexer and attach the battery with the switch so that I can take the MCU off the breadboard
- Print a case for the MCU+mux+battery component to make it fully wearable
- Print different versions of the soft case with varying thicknesses
- Make enough cases for both the left and right LRAs
