Jason Huang
Accomplishments:
- Started integrating Emily’s 3D data into my code
- Still hoping to fine-tune some of the other parts of my code; can partially detect 3D faces, not 100% successful
Upcoming Work
Will continue working with 3D data, and hopefully making the 3D facial detection a lot better at detecting fake faces.
Schedule
Made decent progress, but hope to move forward more as we are headed towards the end of the semester. In the next few weeks, our team will come together and figure out how to integrate our three parts together.

Things were going ok but then they were not! I managed to get a bit of facial data over to Jason, but then for some unknown reason either the RPi or the camera/camera firmware stopped working (some uvcvideo error) and the Pi can no longer detect the camera when running the picture taking script even though it’s technically there when I run “usb-devices” 🙁 Have been struggling with this for a while, but nothing yet. Might have to re-install everything on the Pi and hope for the best 🙁
In happier news, the servos turn a deadbolt now! I’ve also been working on designing the outer enclosure so that all the buttons are accessible and the camera gets enough field of view.

This week I was able to build the switching circuit. Theoretically I should be getting good power, but in reality I’m getting around 1/10th of our required amount of power. The coils are also coupling very strangely, as they seem to couple more intensely when further apart (around 2 door widths is where they are optimally coupled). Getting 30V, 10ma at that point with a 9k Ohm load. Short circuit current is 300mA. Theoretically the optimal power should be 1/2 open circuit voltage * short circuit current, so should be getting enough power, but that is not the case! Unsure what is going on at this point, so will need lots of help next week!
