I'm doing a video about my elab experience /tour of Kingston. So spent the week filming Jamaica. Instead of getting the typical resorts, sports bars and obviously ganja farms, I opted to show the local side of Jamaica. The side that tourists don't see, and even most Jamaicans don't see.

The video is on google drive until I can find a fast connection to upload it to youtube, so voila:

We took a lux level survey throughout the tennis courts. Then I made a color-scaled visual representation of the data using Google Sheets and their color IF function. Bill also introduced us to databases using MySQL. Then he described the mechanism by which hard drives 'delete' data.

Today Bill showed us the MySQL server. But the juicy part was when he described the physics of deleting files. A hard drive saves data as binary - ones and zeros. There are tiny magnetic objects that are either charged positively, 1 or negatively, 0. When you delete a file, it's not actually deleted. The original charge remains, and the computer just allows new data to be written over it. Even via a 7 pass secure erase, where there are seven passes of recharging, the original charge can still be accessed at the bottom of the object. I don't understand it fully, but it's interesting.

Today we used a lux meter? to survey the strength of light throughout the tennis center

Didn't do much this week. Got sick for a day and recovered. But, the battle with senioritis is a hard one.
Talked to Bill about starting a welding project. We're discussing materials next week.

Refreshed my memory on some Xcode today. Glad to be back in the game.

Mostly caught up on spring break happenings today. Also redirected my focus for my final quarter. I'll finish HPA by focusing on Xcode and welding.

Bill is installing a kiosk above the shelves outside the cafeteria. We headed down there to measure the space to see how the monitor would fit. I'm a visual guy, so I drew a sketch:

This week I shifted wireless media. I took a break from heat mapping. I helped set up a wireless receiver and transmitter on the golf carts. It receives a wifi signal from an access point nearby, then transmits it so passengers in and around the golf cart can use it. Now that's wireless. Then, Yerden and I drove around campus testing the strength at different areas around campus.

Yerden and I reinstalled the antennae on the two seat golf cart. Instead of having them side by side, which would cause their signals to somewhat cancel each other, we positioned the receiver on the roof and the transmitter right beside our heads. So we had to redo the signal tests we ran the day before.

When Bill sends the picture he took, I'll post it.

Erin hooked up two wifi antennae on the golf carts. One acts as a receiver, which takes the signal from the closest access point. The signal is transferred to the transmitter antennae, which re-broadcasts the signal. Yerden and I drove around campus to test which areas gave the strongest and weakest signals.

This week the wifi survey was officially started. I finished GPAC and the music room in only a session. 2 down, the entire campus to go.
Bill's physics crash course blew all of Braithwaite's students' minds. He taught them about how a body moving closer to the speed of light than another experiences time slower in comparison to an external body, the fact that our eyes experience light stimulus slowly and so what we see appears to be still, but is actually dynamic and in the form of particles. He talked about optics and how they're used in telescopes, then told them how future telescopes will be synonymous to camera pixels, collecting terabytes of data per second and how it can be used to see back in time and find the first particles created from the big bang.
All wonderful stuff. The world is beautiful place once explained.

I thought I was continuing my survey today, but I forgot that being Bill's student means knowing anything can happen. Jeff and Yerden were MIA, so Tung and I went with Bill to Braithwaite's class. They were reading Faulkner's 'As I Lay Dying' and Bill gave them a physics crash course to help them achieve a sense of comprehension of the phenomena occuring in Faulkner's mind.

Today I planned on continuing the wifi survey, but the Netspot app didn't seem like the one I was using before. I checked the version and it was dated 2008 or something. Someone must have accidentally deleted it, tried to redownload it, but got the wrong version. So I updated it and asked Bill to reactivate the pro package.

We set up the wide screen as a home theater and tried it out with The Martian.

I worked on Xcode lessons. I learned about a variable returning a nil value, arrays and loops

We upgraded the golf cart batteries, gave it a new tire and broke the gear box.

Did more work on the golf carts. Replaced all the dead batteries with new, heavy ones.

Then we waited on Charlie to bring a spare tire, pumped it up and were ready to go.

But a wire connected to the gear box was corroded, so it broke off when we tried to switch on. We'll figure it out next week.
