Monday: Today I finished the height calculations for the standoffs so that they sit at the appropriate height for the picking mechanism. I also made the drawings for them.
Tuesday: Today I finally received the last of the solenoids for the project and I assembled those onto the crossbars and placed the TPU caps on all of them.
Wednesday: Short perioids so I didn't accomplish anything noteworthy.
Thursday: Today I labeled the solenoids based off the notes that they will be playing and we stayed after school in order to begin to test the program. The program worked but we need a better power solution.
Friday: I had originally labeled the notes wrong so I went through and redid those to be correct for a left-handed guitar.
Monday: I was on an orchestra field trip to EHS. Began manufacturing aluminum parts for the guitar picking mechanism. I taught James how to use a manual mill to make the parts accurately.
Tuesday: No school.
Wednesday: Made some small changes to the website. Answered questions from Frederick. Made a plan for testing. Gave files to James to be 3D printed.
Thursday: Tested fretting mechanism with the new rubber caps. When pressed my hand, the solenoids where able to change the note well. I then energized the solenoid and it was able to change the note but produced a buzzing sound. I believe this is because I need to move the point where it presses on the string closer to the fret. I will also remake the caps to be more squishy to experiment.
Friday: Another orchestra field trip to NIU.
Manual actuation testing (Bass is out of tune)
Energized solenoid testing
Monday: Soldered new IC sockets onto the PCB, but the headers are still on until I get desoldering wick. I also started soldering together the PCB for the Organ
Tuesday: I started wrapping up the hole drilling for the top of the Organ, it should be done by the end of the week since there are only 4 more holes to drill.
Wednesday: Finished drilling the 4 holes with the short period, and tested the Teensy with the Pi to test with the PCB, but there was a delay.
Thursday: Finished soldering together the Organ PCB Getting all of the connectors and ICs.
After Thursday: Mr. Rojas hosted an out-of-school project-work-time. With this time, we discussed the project, and did some PCB testing. After Luke and James left, I worked on finishing cutting the sides of the wind chest so I can stain it over break.
Friday: I tested the PCB and found a mistake: I didn't connect the 12V for the 2nd IC. I will use a jumper to complete the Schematic.
After Friday: We tested controlling the solenoid using the PCB and Teensy connected to the PI.
