Uff, that was a busy week. My regular work, handling the orders at PCBWay, having long Skype discussions with Ermanno about the best test scheme and polishing up the project site for the contest. In particular, I realized that my video was 6:30 min and only 5:00 min were allowed. I's 4:58 now. Forgive me the somewhat strange cuts in some places. 

Let me go through the checklist:

i. Build a working prototype of your project.

• Working prototype of STAGE1 (made from breakout boards)
• Working prototype of V1 board that still required external breakout boards for the chip level sensors which were just not hand solderable. Please see the test documentation in the project logs.
• Prototypes of V2.0f board are ordered but obiously we couldn't test them yet.

 ii. Create a video, between two (2) minutes and five (5) minutes in length:

• It's 4:58 

iii. Project Profile: On the Project Profile: 

 a. Link to the video 

• Done and tested.

b. Post high-resolution photos of the project inside and out 

• For STAGE1 refer to 2021_08_14_Full_description.pdf
• For STAGE2 refer to the logs and the renderings in v2_0f_board_for_solar_tracking_and_robotics.pdf

c. Update and add detail to info entered at the previous stage(s) 

• Done

d. Show at least ten (10) Project Log updates or at least ten (10) Build Instructions updates 

• This is project log No 24 and I asked Ermanno to say hello in Log No 25 and prove that I didn't just invent him to simulate teamwork. We should be fine.

e. Post a components list that is complete with a bill of materials for one unit 

• For STAGE1 refer to 2021_08_14_Full_description.pdf
• For STAGE2 look at the Excel file in here Magnetic_CPV_Tracker_v2_0f_Eagle_CAD_CAM_BOM_documentation.zip

 f. Post reproducible build instructions 

• I put a lot of effort into the build instructions for STAGE1 2021_08_14_Full_description.pdf
• For STAGE2 we don't recommend trying to solder this board yourselves. Have it assembled professionally or apply for one of  our prototypes at a cost share of $40. 
• I describe our plans of how to mount and encapsulate the board here. v2_0f_board_for_solar_tracking_and_robotics.pdf

 g. Post complete schematics and documented input and output requirements and specifications for your module/design h. Publish all design files Including Gerber files (req – RS274 / RS274X), STL files (opt), netlist (opt), nc drill files (req – human readable), ODB++ (opt), STEP (opt), PCB files (opt), or any other design files

• STAGE1 uses a clever assembly of breakout boards with a minimum amount of wiring and without any extra PCBs 2021_08_14_Full_description.pdf
• For STAGE2 all the required files are in here Magnetic_CPV_Tracker_v2_0f_Eagle_CAD_CAM_BOM_documentation.zip

I's all there and I feel good about it. I guess we reached a fair level of openness. All publications are under MIT license and we promise to add the test board design and operating instructions for the V2.0f board once everything is working. I may also invest time into the adaptation of this board to robotics (I2C slave) but I cannot promise that yet. It would be great if a 3rd team member (or more) could take over that job. And then it all depends on finding a community and a company that will use the board for solar tracking on large scale.
