I was doing my project the whole day, I really feel like giving up. Only one week left, and I am coming to terms that I may never finish my project. I'll never really see the fully functional watch that I've so optimistically and ambitiously envisioned. But I am still trying to do my best and produce some boards so that I am not entirely empty handed when I go for the review.
Then it rained cats and dogs throughout the week and people left early. Ok so for my CT I scored best for one paper at 94, my other two papers barely scraping past 76. No one else even crossed the 90 mark, but considering how poorly I did for the other two papers, I didn't feel the usual elation.
After all in BME, if you get too high, it's a taboo and everyone looks at you differently and you always try to defend yourself by saying that the marks you got isn't that great after all and you bring out all the bad points that you have so that you "lower" your image to their level and become "normal".
It's all screwed up. I don't know why there's this pathetic mentality in poly that students are proud when their results suck. Students compare how low each one got for each of their papers. You don't see this happening in JC! Where students are actually worried on how low they get and are actually shameful of a poor grade. Anyway, CT aside; I haven't been updating because I have been busy with my project, I know many people have asked me on the progress of my project, so I took some pictures. The final review is coming up.
To all those who have supported me mentally, psychologically, this is what we have all achieved together. Basically my project is to design a watch as a health-monitor with alarm functions.
It has a Bloodpulse sensor, a Motion-sensor, a temperature-sensor, a 8-bit microprocessor running at 26kHz, Bluetooth module and Panic alert.
These are the individual boards, From top left clockwise, the first bloodpulse sensor, the accelerometer/temperature hybrid board, the current bloodpulse sensor with improved IRphototransistor sensitivity, the Op-amps used and the largest board is the motion-sensor filter-processing board. I won't be showing the processor and bluetooth here, they're on separate boards.
Soon there'll be a project exhibition and you'll see everything that I've done then.
All the components are to be integrated into a WATCH. it's about 4x4x1.5cm. I think it's already an achievement to reach this level of integration and miniturization. I wanted to tear my hair out as I designed this board. It was like designing a mother board for ABIT.
So you can see the watch chassis, and the boards that are to be integrated into it. Soldiering of the components have not be completed.
The top layer is the processor, you can see the processor chip, it's about the size of a 10-cent coin. Several SMD alert buttons.
The improved Bloodpulse sensor module.
See all the components on the right? I have to find a way to squeeze it into the chassis on the left.
1 more week left. See what I can do. Been working 20 hours a day trying to complete this project. Another update soon.
Back to work
