“eh where is the rest of your group?”
Starting school and finishing up MnT project is quite a challenge. Jing Rui and Zheng Xun were busy settling online codes and the front end of the webpage, leaving Anita and I to figure out the hardware. One pressing concern was how the batteries were going to power the entire system in time for the pool test, ideally on Thursday.
Having pulled out at the last minute twice due to code failures and lack of preparedness, sticking to this booking of the swimming pool was something that we intend to keep, functional code or not…
Unfortunately, Anita was busy, and so that left me to fend for myself at the lab… Thankfully wifi connectivity has allowed communication to be so efficient, I could access my team mates any time!
And so with a new group dynamic, the first thing we completed was the placement of our components:
<b-roll>
this was the inital layout, where I placed the router together with the NVR, thinking that due to the LAN cable required to be connected for the 2, this would prevent a lot of sprawling cables.
But Tony mentioned that masking taping over the vents was a poor idea, and that cables can be arranged anyway, and since the router antenne needs to be out of the boat — it was a better idea of attach them individually.
this is the set up getting ready to test the pumps for the battery!
the next thing i was able to complete was creating an insulator for the cables. Without the appropriate size of heat shrink cable protector, the next alternative was using the glue gun…
so after removing the temporary masking tape, it was time to exercise some workmanship!

and finally, the batteries, which Tony was kind enough to guide me through the entire way. And also, point out the problem.
The problem with the battery is the input of 14V results into a 14V output as well. But the problem is that our NVR can only take 12V maximum.
Or at least, we were trying to verify that — Limsy used a microscope to try and read the chip, and alas, Google for the first time, didn’t have any search results.
^ the microscope!
So that meant we didnt have a power source… Tony suggested using a buck booster (or, bulk booster?)
which hopes to limit the output to a fixed 12V. The problem now is how soon we can get our hands on this, since it is not something commonly found in hardware shops…
Tomorrow, its Anita’s turn to take over as my day is packed, and another story to unfold!
