More HD experiments

Living with an electrical engineer is always…interesting. I’m also an engineer, but my desire to tinker is more software-oriented than hardware, whereas Damir likes to build things. After our initial experiments with the HD TV antenna that we bought for $35, he started researching on the web, and ended up building three other HD antennae.

HD antenna 2.0 - the first homebuildFirst up was actually the most expensive of the home-builds, since he bought heavy-gauge wire instead of using the coathangers suggested in the YouTube video that inspired it. It was mounted on a piece of Ikea shelving that we had lying around (if it had been the final version, we would have trimmed it back just to a single wooden stick), and consisted of the above-mentioned copper wire ($13), a TV matching transformer (needed on all the antennae to convert the signal to the coax connection to go to the TV, $1) and some screws for that shelving that we already had. With no amplification, it worked as well as the commercial one that is amplified, although we couldn’t find the sweet spot that allowed us to get all 7 HD channels — or at least the 5 that we care about — without moving it around. Also, it could have put out someone’s eye.

HD antenna 3.0 designThat night, he took his copy of the ARRL handbook to bed to brush up on his antenna theory.

The next model, a discone model, never made it past the early prototype stage. Shown here is the cone part (he was still working on the disc part), which would have been covered with aluminum foil. He later found this to not be the right type anyway, but he had fun making (and wearing) the cones.

More research ensued.

HD TV antenna 4.0The 3rd version, a.k.a. HD antenna 4.0, is what we’re sticking with for now. It’s made of two sections cut from aluminum foil (yes, the type from the kitchen) taped to an old wooden ruler. The sections are connected on one side by a 390 ohm resistor (4 for $0.25), and on the other by the TV matching transformer. You can see a close-up of the construction in an earlier phase when he was trying it out on a larger board here; he calculated the exact size of the foil pieces from his antenna theory textbook. Technically, it’s a T2FD antenna.

The antenna-on-a-ruler is attached with 2-sided sticky pads to an old wooden salad server, then mounted on an unused tripod to allow us to easily move it around to find the right spot.

With this configuration, we get the five main HD digital channels that we wanted without moving the antenna: CBC, CTV, CityTV, Global and Sun TV. We can also get Omni 1 and Omni 2 if we move it around, but we rarely watch those so aren’t concerned about it.

Keep in mind that we are less than 1km from the CN Tower, but are west of Spadina and face west, so we’re bouncing our signals off the surrounding buildings. When we tried our Philips antenna (the one that we bought) at a neighbour’s place that has a clear line of sight to the tower, it picked up 7 or 8 HD channels with no fiddling, and several VHF channels as well (since her TV used a single feed for both analog and digital tuners).

I’ve now cancelled our Rogers cable, which will take effect mid-August. The only remaining thing is to use the (currently unused) Philips antenna as a VHF antenna to pick up the lower-range analog channels and feed them to the DVR (which has no digital tuner) and then on to the TV via the HDMI connection — if we get any decent reception on VHF, that will allow us to watch and record those channels.

Blogging from the Wii

Okay, I don’t think that I’m going to do this very often, but I just have to prove that I can. Tonight, I downloaded the Internet Channel to my Wii (500 Wii points = $5), and I have a fully-functional Opera browser. So here I am in WordPress, typing a blog post on my Wii. I cheated a bit and am using a USB keyboard attached to the back — the thought of doing this one character at a time using the Wiimote was just too much for me.

It seems to enter carriage returns in this entry field okay, but links didn’t work when I entered the HTML code.

Book review: Stuck in Downward Dog

My first book to review from MiniBookExpo, and I picked a light “chick-lit” read to complement the summer weather: Stuck in Downward Dog. Chantel Simmons’ debut novel is a pleasant, humourous read about Mara Brennan, a mid-20’s woman who hits a rough patch — job, boyfriend, apartment, friends — and gets through it while learning something about herself and her friends.

There were a lot of things that I liked about this book. First of all the Toronto setting was used well, and there were great insider references, such as when Mara’s friend tried to pass off her new Mississauga location as “Port Credit” (an accurate place name, but to anyone who lives in the 416 area code, it’s all just undifferentiated suburban wilderness). I was pleasantly surprised to find out that a new boyfriend does not figure in her miraculous turnaround — in fact, Mara does it pretty much on her own, with a bit of help from her friends. There’s a nutritional epiphany about a healthy-sounding smoothie. There’s some great inner monologues of Mara’s thoughts during yoga class.

There were parts of the storyline that could have been improved. First, Mara spends 25 years getting herself into a complete disaster of a life, including the worst two months of it chronicled in the first part of the book, then manages to turn the entire thing around in 3 weeks. A bit unrealistic, considering that she comes off as a bit of a naive pushover. The two girlfriends were painted as cruel caricatures; if they were really such bitches, I can’t believe that Mara, pushover that she is, would have been best buds with them all this time. She refers to her size 10 body as if it were bordering on obese, which is not a great message to be sending to her target audience, even if they are pigging out on those calorie-laden smoothie.

In spite of its flaws, I found Stuck in Downward Dog to be a fun read with lots of laughs, and may even be inspirational to young women who are looking for the courage to find the right job, the right apartment and the right relationship with their friends.

HD OTA experiments

An online conversation with a few friends last week got me thinking harder about something that’s been on my mind lately: is it possible to get rid of my Rogers cable subscription, and get TV signals the old-fashioned way: with an antenna? This is now referred to as “OTA” (over the air) for those in the know, and there’s a whole range of digital HD channels that you can pick up in addition to the old familiar analog ones.

We already had pared back to the most basic analog cable plan, with no desire for several hundred channels of additional crap that we wouldn’t watch at additional cost, and when we got the Wii a few weeks ago, our TV watching dropped to less than an hour per day on average. We rent movies a couple times a month, read a lot of books, and, of course, there’s the internet: a vast library of fascinating material in a variety of formats. Although the US networks and Hulu block viewing of full TV episodes from Canada, some of our networks do show full episodes online of a few programs, such as Mad Men on CTV.

So, for the cost of one month of our basic cable, we picked up a Philips indoor DTV/HDTV antenna to see how OTA would work for us. We live near Richmond and Spadina, in a west-facing apartment on a low floor: that means that we face away from the CN Tower, source of most OTA signals in the Toronto area (although within 1km of it) and have a lot of taller buildings in the way.

We plugged in the antenna to the DTV port on our TV, scanned for channels, and wham! There was CBC in beautiful HD, completely without distortion. A few hours of playing around, and we found 6 additional channels, including CTV and Global, which syndicate many of the popular US shows during evening prime time. Here’s the rundown of what we can receive:

Station DTV channel Zap2It channel
CBC (CBLT) 5 5
CTV (CFTO) 9 9
Omni 2 (CJMT) 44 69
City TV 57 57
Omni 1 (CFMT) 64 47
Global (CIII) 65 6
Sun TV (CKXT) 66 45

The Zap2It channel is the corresponding channel if you use Zap2It for TV listings, and select Toronto - Local Broadcast as the source: I set my preferences on that site so that I see a grid of only these stations, in this order, as my TV guide.

Unfortunately, we haven’t found a single position that brings in all channels: CBC, Global and CTV seem to be best when bounced off the top of a taller building to the southwest of us, while SunTV is best reflected from the building directly across the road. CityTV and the two OMNI stations are picked up when the antenna is pointed directly towards the tower, that is, through our building. We’re still experimenting, and need a longer cable so that we can try some other locations within our apartment. If we lived in a higher or south-facing unit, I’m sure that the results would be radically different, and we might even pick up some Buffalo stations across the lake if we were high enough, but this is good enough for our TV-watching habits.

Argentine Malbecs in Ontario

I don’t blog for the Australian Wine Society any more, but I still like to lift a glass, and I subscribe to the excellent winecurrent.com newsletter that provides reviews of wines just before their release at the LCBO. On July 5th, a number of Malbecs from Argentina were released, and here’s the ones reviewed by winecurrent.com, with an excerpt from their review:

Finca El Origen Reserva Malbec 2006, Uco Valley, Mendoza $14.95 (065664): “Easy-drinking red that provides good value.”

Finca Flichman ‘Gestos’ Malbec 2007, Mendoza $15.95 (068999): “Complex and alluring…enough tannin for structure and interest plus generous acidity for impeccable balance; the 8 months of French oak has been seamlessly integrated. Give thought to a multiple purchase.”

Finca Flichman Reserva Malbec 2007, Mendoza $12.95 (746727): “rich and ready to drink…serve with all manner of backyard BBQ fare.”

Finca Sophenia Reserve Malbec 2006, Tupungato, Mendoza $16.95 (066837): “chunky mouthful of ripe fruit flavours—cherry, currant and cranberry—oodles of moderating acidity and still perceptible tannin. Temper this with a two-hour aeration/decant then serve alongside a rare to medium-rare grilled strip loin.”

Navarro Correas Gran Reserva Malbec 2005, Mendoza $18.95 (028928): “one of those Wow! wines that immediately grabs your attention with its great balance, delectable fruit-forward flavours and lengthy finish.”

Weinert Malbec 2003, Mendoza $18.95 (556795): “round n’ ready to go, but is certainly not without class or complexity.”

You can also see the LCBO’s reviews of the Argentine Malbecs here.

Wii Workout: Day 7

Whoever said that you can’t get fit on a Wii Fit never tried the Expert level of Rhythm Boxing, or even Super Hula Hoops: 2 minutes into the 10-minute boxing session, the sweat is running down my back. You can get fit with this, and I’m on a mission to drop some weight and get fit over the summer while my travel schedule is light.

The Wii Fit journey started in late May, when we scored one for my mom for her 85th birthday and had a fun weekend at their place trying it out; a week ago when we returned from holidays, we picked up one for ourselves. After having to reset the first few days of results due to an error in setting the original date (the Wii does not shift the date of your results when you change the date on the device, making for some weirdnesses: get it right the first time), we’re now on day 7 of using the Wii Fit.

One big benefit is the daily body test: each day, you can check your weight and balance — the Wii uses balance as a measure of your fitness — and track your weight and BMI on a graph. That lets me see, for example, that I’ve dropped 2 pounds in the 7 days that I’ve been using it, which is very encouraging. My BMI indicates that I’m over the line from “normal” into “overweight”, and my goal is to get that back into the normal range, which is only 6 pounds away at this point, and further into the range to be close to the ideal BMI of 22.

The Wii Fit gradually unlocks the full range of exercises available as you accumulate time, and I have most activities unlocked (except for some of the strength exercises, which I’m not using yet); some activities also have basic, advanced and expert levels within them, so there’s even more variation that you might guess from the initial menus.

Although I do want to work on strength eventually, my morning workout current consists of about 30 minutes of aerobics — a combination of the advanced step class and rhythm boxing to get both the upper and lower body working — and 30 minutes of yoga once the muscles are warm from the aerobics. The yoga positions are really good, since most of them are done on the Wii balance board, and correct your position by noting when you’re off balance. It has a demo for each yoga position, telling you what muscles to contract and how to do the move, and an on-screen instructor does the pose with you. I’ve had pain in my left shoulder for several months now, and the yoga is helping it a lot.

There’s also balance games, which are fun and do help improve your balance and therefore build up some of your core muscles, but not really a workout: I use these mostly when I want to take a break from my desk.

The real advantage for me is the ability to do all this in my living room: although there’s a gym in our condo building, I rarely use it since even the minimal hassle of going down there seems too much, and takes me away from my phone in case of a client call if I’m working out during business hours. Also, the Wii is just a lot more fun.

MiniBookExpo for Bloggers

Wow, it’s been over 3 months since I posted here: work and travel have taken up most of my time. I have a ton of billable work to do over the summer, but there’s always time for reading. A couple of years ago, I rediscovered the Toronto Public Library, which was a godsend for me when I was young, providing me with an endless source of books to feed my voracious reading habit. Now, they have their catalogue online, and I can order a book from anywhere in this huge system and have it appear at my local branch.

This week, I saw a link to MiniBookExpo for Bloggers, which promises to be another source of interesting books. They list books that are available for review from the publishers, you add a comment to the post about the book in order to claim it, they send you the book, and you review it. Shipping is free, and there’s nothing about having to return the books, so I can pass them along to the book collection in my condo, or even donate them to the public library if I can figure out how to do that. Looking forward to receiving my first book for review!
