Diary
- Created and made sure the BOM and PIP files matched and worked for JLC PCB.
- Made a budget sheet to request funding from Gummi and the school.
- Took a look at the 3D files and tried printing the most important parts to see if it would be smarter to order them from JLCpcb aswell.
- All parts except the lilygo microcontroller have arrived. Everything looks good and almost ready for assembly. We need some small items such as, VHB tape, small wires for the display, screws, finish the 3D print.
- All parts arrived and assembly of the first knob started.
- Ran into a few assembly problems such as order of assembly, rare to find 1.6mm screws, screen ribbon cable hits the inner side of the encoder housing when turning.
- Got the first knob up and running, however, the functionality of the haptic feedback did not work as expected.
- Started writing the paper on this project.
- The assembly of the second knob was started.
- Continued on with the paper as well as the assembly of the second knob.
- When the second knob's firmware was flashed and the knob tested, we noticed the haptics were working as expected. At this point we figured that there must have been some issue with the motor in the first assebly. However, the screen on the second assembly smoked due to a short circuit in the soldering of the flat-cable for the screen.
- Assembly of the third knob was started and also finished. When flashed with the firmware we found that the screen on that assembly was defective and did not work.
- Repairs started on all knobs.
- Disassembling the motor on the first knob revealed that the windings on the motors were damaged due to the mounting screws being too long and damaging the coils.
- Repairs on the third knob were finished and it was tuned to the correct functionality.
- Repairs on the first knob were finished .....
