I’m Twittering

August 12th, 2009

Or it is “Tweeting?” I’m not sure. Whatever it’s called, I’m doing it. I resisted Twitter for the longest, just like I did with Facebook, but I finally gave it a try a few weeks ago.

It gives me a nice outlet for things that I find interesting, but not quite interesting enough for a blog post. It’s certainly not for everyone, but if you enjoy my blog posts, you might enjoy following me on Twitter.

I’m using TweetDeck as my desktop client, though I haven’t been able to get it installed under Linux just yet, even though it’s supposedly compatible. I also use TwitterFon on my iPhone.

Our Wiggles Experience

August 11th, 2009

As I mentioned last week, we went to see The Wiggles in Memphis at the Cannon Center. I’ve finally gotten around to processing the pictures I took, and you can see them all here. The front row is a very picture friendly spot, though maybe not the best place for small kids.

When got to the Cannon Center, Liam had been cooped up in the car most of the day, and he decided that he was not going to be happy unless we let him crawl around. Luke was enjoying himself until he tripped and fell pretty hard. I think that threw him off the rest of the night.

Neither of the boys were as enthusiastic as we had hoped. They never took their eyes off the stage, but the big smiles we were expecting just weren’t there. Cassie and I have speculated as to the problem, but we really have no idea. Luke was dancing and singing to one of his Wiggles DVDs before we got out of the parking garage. It’s just one of those things I suppose.

All that said, we’d go back in a heartbeat. In fact, Cassie has already been trying to talk me into catching another stop on this tour. It’s probably not going to happen, but we’ll definitely see them if they come back to the US in a year or two.

We were under the impression that they would do mostly songs from their newest DVD. That had me a bit concerned, because they boys haven’t seen that one yet. As it turns out, they did maybe one song from their new DVD. the rest were old favorites.

Ole Miss ranked 10th in preseason poll

August 11th, 2009

The preseason USA TODAY Coaches’ Poll was released last week and Ole Miss is ranked 10th behind SEC teams Florida(1), Alabama(5), and LSU(9). We could certainly be that good, but I want to see a little football played before I get too excited.

After our 9-4 season last year (with the bowl win), it’s going to take at least nine regular season wins to keep the fan base happy. We have a reasonably soft schedule, so If we’re anything like as good as they say we are, 8-4 in the regular season should be no problem. Alabama, Auburn, Tennessee, and LSU will be a little tougher, but are all beatable.

We’ll know a lot more after the Memphis game. I’m hoping for a blowout. Anything other than a solid win and we start dropping in the rankings.

The Wiggles

August 3rd, 2009

Both Luke and Liam enjoy TV, for better or for worse. When Luke was about seven or eight months old, he decided he didn’t like riding in the car unless someone was sitting back there playing with him. That wouldn’t work so we bought him a portable DVD player for the car. At first he only got to watch age-appropriate Baby Einstein DVDs. At some point after he turned one he got bored with those and Cassie and I went to Toys ‘R Us to get him something a little more exciting. After a brief discussion we decided on a Wiggles DVD. If we had only known.

Luke and Liam now have four or five Wiggles DVDs. We have around a dozen Wiggles TV shows “TiVoed.” Wiggles was all Luke watched for a long time. His interest has now branched out into Handy Manny, Mickey Mouse Clubhouse, and Imagination Movers, all Disney shows. Until recently he only had Wiggles DVDs, we just recorded the other shows. Before our trip to the coast we bought him a DVD of each of the other shows. Liam loves the Wiggles too. It’s definitely his favorite, but he enjoys Mickey Mouse Clubhouse too.

The Rockstar

Several months ago we got Luke a Wiggles guitar. For a long time he took it everywhere: the grocery store, restaurants, and one time, even church. Now he’s content to leave it in the car when we get out, but he still has to make sure it’s in the car before we leave. He plays along with the Wiggles, the Imagination Movers, or any other show with a guitar.

Several months ago we found out the Wiggles would be doing a tour in the US. We didn’t know when or where, but Cassie and I agreed that if it came anywhere close, we’d have to take the boys. Then, one day, after months of anxious waiting, the email announcing the tour came. Unfortunately, the closest concert wasn’t very close; Atlanta or somewhere if I recall.

Cassie ended up on the Ticketmaster web site somehow, and happened to notice that they had a Memphis date listed for the Wiggles tour. For whatever reason, the Memphis date wasn’t originally listed on the Wiggles site. Maybe the details were worked out at the last minute or something. In any case, because no one else knew about the Memphis concert, we managed to get front row seats.

The concert is tomorrow, and I think Cassie is more excited than anyone. :) We’ve been telling Luke about it for the past day or so, but I’m not sure he understands the “in person” concept. The Wiggles show up inside his TV at least once a day, after all. I think they’ll both get it when the concert starts though. It should be fun. I know video cameras aren’t allowed in the concert, but I’m hoping to be able to take pictures. We’ll see.

Luke and Liam update

August 2nd, 2009

Since my last update, Liam is crawling all over the place and pulling up on everything. He’ll play in the living room for a while, then move to the “dining room” (aka their third play room), make a loop through the kitchen, and then maybe go play is his room for a while. He doesn’t particularly care if anyone is playing with him or not. In that respect, he’s more independent than Luke was at his age (11.5 months).

Liam loves to play “chase.” He loves for Luke, or for that matter, Cassie or I, to crawl after him. He thinks it’s great fun. He and Luke are getting to be pretty big buddies. Most of the time Luke remembers that he’s still quite a bit bigger than Liam, but occasionally he gets too rough for our liking. Sometimes you’d think he’s been watching wrestling. :)

Liam’s spitting up has gotten much better. Good enough, in fact, that we’ve tried mixing whole milk into his bottles. Unfortunately, it seems to make him spit up quite a bit more. We’ve stopped for the moment, but will probably try again soon. Hopefully it was a fluke. I’m anxious to get him off his ~$50/week formula habit.

Luke’s learning new words at a pretty rapid pace. He’s still not saying a lot of phrases, but that seems to have improved in the past week or so. At least to me, it’s obvious he’s a pretty smart little kid, we just need his verbal skills to catch up to what’s going on in his head. I have no doubt that’ll happen in time.

Going back to school

July 29th, 2009

I got my Master’s degree in Computer Science in May of 2007. Luke was born about three weeks after graduation. Liam was born fourteen and a half months after that. Liam is nearly a year old now, and it’s time to go back to school and get my PhD.

I had planned on taking it easy the first semester and just taking one class. However, I was asked to teach a class, which comes with a partial tuition waiver, so I’m going to take advantage of that. I’ll be taking Dr. Rice’s Computer Audio course, ENGR596, as well as an independent study course. I’m not sure what the independent study course will be just yet, but hopefully it’ll help me decide on a topic for my dissertation.

The class I’m teaching is CSci103, which I have always described as the “this is a mouse” course. In the past I’ve always taught courses for sophomore or higher Computer Science majors with a few MIS majors thrown in (CSci223 twice and CSci323 once). They tend to take the class somewhat seriously. This time I’ll be teaching mostly freshmen, most with “non-demanding” majors. It will certainly be different.

In addition to teaching a class and taking two classes, I’ll be studying for comprehensive exams (to be taken in a year or so) as well as researching and trying to get published so I can get hired as a professor when I’m finished. It’s fair to say my hobbies and my family will be neglected to some degree.

When will I be finished? I’m going to say four years, which will have me graduating in the Spring of 2013. I could finish a little sooner (or a lot later), but I think that’s a realistic timeframe if I keep on task.

The Godfather

July 28th, 2009

I watched The Godfather for the first time ever a few nights ago. I’m often disappointed at movies that are supposed to be great, but The Godfather really is great. Watch it if you haven’t. It’s #2 on the American Film Institute’s list of best movies.

Next up? Number 1 on the AFI list, Citizen Kane from 1941.

Small Wonder Labs SW-40+

July 27th, 2009

As most of you know, I’m currently afflicted with the ham radio bug. I have a VHF radio I can use to talk locally, but nothing I can talk around the world on. For Christmas last year, Cassie got me (at my request) a Small Wonder Labs SW-40+ 40m QRP CW transceiver kit.

The 40m ham band is a good all-purpose band. It’s open to somewhere pretty much any time, day or night, even at this point in the solar cycle. QRP means it’s low-power. In this case, around 2.5 watts. Most commerical radios put out around 100W. CW means it only does Morse code, no voice, which means I’ll finally have to learn Morse code.

The SW+ series is well-regarded in the QRP community. There are models available for the 20m, 30m, 40m, and 80m bands. The kits are put together by a guy in New Hampshire. There’s a waiting list of around two months to get a SW+ kit.

Partially assembled SW-40+ board

The SW-40+ board with 8 of the 16 sections installed. I've added a couple of sections since this photo was taken.

A few weeks ago I finally got a chance to start putting mine together. The instructions that come with it basically say to build the whole thing, then test it. I’ve built some smaller kits before, but this is definitely my largest undertaking thus far, so I wanted some assurance things were going right as I built it. So, I’ve been using Chuck Adams’s, K7QO, guide to building the SW-40+. By following his guide, you build a section, then test it. He has it broken down into 16 sections, more or less. Some of the previous kits that I’ve built are used for testing.

You can see all the pictures from the construction process here. I’ll continue to add photos as I go along. I’ll post an update here occasionally too. So far I’ve installed the power supply, audio amplifier, keying, muting, audio preamplifier, receiver mixer/detector, IF crystal filter, receiver mixer, VFO, and transmitter mixer sections. That’s 10 of the 16 sections.

Testing the transmitter mixer section

Testing the transmitter mixer section by feeding the output of the transmitter mixer into the receiver.

A few months ago I bought a VE3DNL Marker Generator kit, but had never put it together. Chuck suggested using it to test the receiver mixer/detector section. It was a quick build, and the receiver mixer/detector section passed the test.

Testing Receiver w/ VE3DNL Marker Generator

VE3DNL Marker Generator board is on left of SW-40+ board. The VE3DNL transmits tones every 5kHz that can be picked up in the SW-40+ receiver.

After building the VFO section I wanted to have a look at the waveform. Chuck’s guide shows a nice sine wave. A friend had loaned me an oscilloscope for another project a few months ago, so I drug it out and set it up. To make a long story short, I was never able to view the VFO’s waveform on the oscilloscope. Something is wrong with either the probe or the oscilloscope itself. However, I was able to confirm that the VFO is running at around the correct frequency with the FCC-1 frequency counter I built a while back.

I have also built a K1EL K12 keyer to put in the SW-40+. As designed, the SW-40+ can only use a straight key. I wanted to be able to use iambic paddles, so I found the K12 keyer. It handles the input from the key and outputs perfectly spaced Morse Code. It sounds beautiful. It’s a pretty cool little device in its own right. I may do a post on it at some point.

More on the SW-40+ when I get a chance to work on it.

Weekend update

July 20th, 2009

Liam woke up Saturday morning with a fever. In addition, you could tell he felt horrible. We thought it was just teething-related issues. Turns out it’s thrush. He’s not quite as bad as he was Saturday, but he’s still not feeling good at all. Poor little guy. That’s two weekends in a row of not feeling well.

Obviously, Liam being sick distracted from Luke’s potty training. I still think it was a worthwhile venture though. By Saturday afternoon he was having very few accidents. Of course, we had his potty in the living room and Cassie was asking him if he needed to go every five minutes. The biggest “problem” is that he doesn’t realize on his own that he needs to go. I guess that will come with time. For now, at least until Liam gets better, it’s back to pullups and diapers.
