What did you personally accomplish this week? Give files or photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).
I worked with Callum on finalizing the circuit diagram for the sensor array. Thankfully we took another look at it, as we ended up needing Op-Amps, something we thought wouldn’t be necessary before. We also found that the hall effect sensors output a constant signal in the presence of a magnetic field (magnets) or phones in general. We previously believed that we’d only be able to detect a phone moving into range, not its position once stationary. While this will likely simplify later calculations and algorithms, it’s also a bit troubling: magnets produce a huge deflection while magnetless devices (many phones) create a very small deflection.
I also finally received the Amazon Prime 2-day shipping linear slides four weeks after placing my original order. While dimensioning them, I found an issue. One of the three cars is either incorrect or machined, manufactured so terribly that its threading is a fraction of a millimeter too small. Because of this, the M3 screws that are supposed to fit, don’t. While we could return it, and order a new one, we don’t believe that to be worth the wait. Thankfully, I was able to force in the screws with a bit of elbow grease. While this is certainly a passable solution, it’s also not a reliable one as the threads in the car or on the screw could break with repeated screwing and unscrewing.
I also had to “spend” time working on the ethics assignment, which took a few hours.
Lastly, my laptop died Thursday afternoon (the power supply to the main board suddenly stopped working). As such, I won’t be able to finalize the dimensions of the CAD and start printing until next week.
Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
I personally believe I am behind as I wanted to have all the parts printing over spring break. However, all the delays are due to things out of my control:
– Orders not being placed when they were supposed to
– Orders arriving significantly later than they should, repeatedly
– Multiple incorrect components were delivered by Amazon
– Laptop spontaneously dying on me
I’m going to do my best to try and catch up next week, but I also have all my other classes to catch up with: re laptop.
What deliverables do you hope to complete in the next week?
The deliverables that were meant for this week, as the only one I accomplished was dimensioning the linear slides. To see them, look at last week’s blog.
