Back to School: Round 3, Week 6

Week 6 already!

I had two tests this week:
Electrical Theory (87.06%)
Code (84.21%)

This week we've finally gotten out of the electronics lab and into the electrical shop, where we've started to learn some programming of a Variable Frequency Drive (VFD). I've installed a few of these, but have never programmed them, it was often up to the HVAC mechanic who had the specs for what was required for the motor.

It allows motors to run at varying speeds, instead of only be turned on or off as needed. This is proven to be a more efficient method of heating and cooling control.

There also seems to be more overlap between the classes. We might cover the same topics in Electronics, Code and Theory, but all from a slightly different perspective. It certainly helps with making the information stick.

There are a couple assignments coming up, but no more tests until the final week, which is all testing.  I get the sense everyone is feeling a bit drained with the additional classroom hours. But, as we're broaching the last of the topics to be learned, there is a light at the end of the tunnel.

The "Social Impacts" of a Female Working with "Mostly Male Construction Workers"

The first time I'd heard anything about comments made by Prime Minister Justin Trudeau was on Newstalk 1010' s The Night Side with Barb DiGiulio .  For reference, here is a section of the comments from Mr. Trudeau at the recent G20 summit as posted in an article from the National Post : " Even big infrastructure projects, you know, might now say, well, what does a gender lens have to do with building this new highway or this new pipeline or something? Well, you know, there are gender impacts when you bring construction workers into a rural area. There are social impacts because they’re mostly male construction workers. How are you adjusting and adapting to those?"    A lot of people are focusing specifically on the "social impacts... ...of mostly male construction workers" part in a negative light. I'd agree, it certainly doesn't sound good, does it? The resulting public interpretation of what that comment meant spinned the narrative to that of t

The Weasley Family Clock Project

I came across this project stumbling around the internet for interesting things, as I tend to do from time to time. I thought it was a great example of a practical use for some of the electronics stuff I have been learning in school. It also serves to feed my Harry Potter hunger. (Long live Dumbledore's Army!) I might not be at this stage of the game yet, but it would certainly be cool to work towards.  It makes use of LED's, and a micro-controller connected via wi-fi. It connects to each family member's smartphones via an app (If This, Then That) to geo-locate the family member and communicate that location to the clock. This lights up the corresponding family member with their pre-set locations.  That app has many more uses. It can be used to connect to your HUB wi-fi connected light bulbs; NEST home thermostat; Belkin's WeMo, a plug adapter that you plug your corded device (like a coffee maker, or your Christmas lights). The WeMo is a wifi enabled device tha

Three Seconds

He's going to hit me. If I try to maneuver maybe- Bang! One One-Thousand. The sound of a scream came from somewhere. I realized it was me. I shrink in my seat, recoiling from the impact. The side airbag deployed, grazing the left of my face and shoulder. I barely registered it. Somehow my right hand wasn't on the steering wheel. "I need two hands, two hands on the steering wheel. Steer!" Things were freewheeling now. I'm not in control. What's next? Two One-Thousand. Look left, the airbag was there. Look forward, but my focus was blurred. I could only see on what was happening inside the car. "Pump the brake, pump the brake, pump the brake!" I hit the curb that bounced me up and over the island. Three One-Thousand. "Pump the brake!" I came off the island into the right turn lane, no one was there. The car stopped. I braced for another possible hit. Nothing. I waz vibrating at a higher frequency. Trembling. I
