A number of people at work cornered me at the end of October and coerced me into participating in this year’s Movember charity event. The concept: grow a moustache (no beards allowed) for the month of November, and use it as an excuse to raise money.

The Movember Foundation aims to raise awareness and money for prostate cancer research as well as general men’s health issues.

I’ve never let my facial hair grow, except for maybe not shaving for a day or two over a long weekend. I didn’t have high hopes for an attractive moustache, and I was certain I wouldn’t manage anything quite as bushy as George Parros (NHL player for Anaheim) but I really didn’t know what to expect.

So far I’d say it is going ok. Not great nor bad, just ok. Visit my MoSpace page to track the progress of the moustache, including pictures, and maybe donate to this worthy cause.

Our friend Jamie wrote about it, expecting a lack-luster moustache. Drop by her blog and let her know whether she is right or wrong.

I have been working, ever so slowly, on a larger wheeled robot. My efforts to date have mostly comprised of collecting parts: motors, wheels, gears, a GPS module, various electronics bits, a nifty digital compass, etc. I’ve finally started design and manufacture of various parts to start stitching together everything.

My first machined part is a bracket to mount the motor (a Lynxmotion model). This picture shows the four brackets I need; one is mounted on a motor, the one in the front-left is finished and the other two need only to have the “tabs” cleaned up.

I designed the part using Inkscape then exported a DXF file and did the machining on my CNC-equipped Sherline (as described in a previous post). You can see the image of the Inkscape design here. This process works quite well for me.

The problem of course is that the design requires “tabs” between the parts in order to be able to hold the whole thing together while machining. I’ve captured a couple of photos here and here to show what it looked like before I cut everything apart.

Next up is the brackets to attach to these mounts. My initial design will take longer to machine though. The idea is to allow each wheel to pivot independently; the bracket is an “L” shape that extends up and over the center of each wheel. It will make more sense when I have some pictures.

I found an interesting AVR32 development kit online that promised to be very inexpensive yet flexible enough for full prototyping. I quickly jumped at the chance to order one of the AVR32 DIL modules, and after a quick email with Rikard Strömmer (the seller) to work out the details I bought it via Paypal. It arrived in the mail last week and I spent a few hours yesterday playing with it.

Rikard sent me the full development kit, asking for some feedback. I found a few very minor documentation errors (he will fix them pretty soon I expect) but otherwise the kit went together exactly as advertised. I took several pictures during the build, you can see them here.

Anyone who already has a well-stocked prototyping workbench doesn’t really need anything more than the AVR32 DIL module, but even so it was very convienent to have just about everything required included - you have to provide your own 9v battery, some jumper wire and a solderless breadboard.

I’ve just started to play with the software side. Atmel makes a very rich software library with plenty of examples available online. They also supply a version of GCC, similar to the WinAVR package for the 8-bit AVR line. It is nice to see them taking the free software approach, makes it very accessible for hobbyists.

Rikard’s instructions have you modify one of the Atmel examples as your first program. It blinks one of the LEDs and uses the push button (left side of the board) to turn the second LED on. The reset button (right side of the board) works too. I made a little movie of it in action, watch it here.

The AVR32 is quite a bit more powerful than the 8-bit AVR processors I’ve been using in my robot projects. I’m not quite certain what I’m going to do with it yet but it would make a great upgrade for the AVRCAM project, or maybe use it for the heart of an inertial navigation unit, or maybe as the brain for a whole new robot project.

Eileen and I finally saw the fourth installment of the Indiana Jones “trilogy plus one”. To say I was disappointed doesn’t come close to accurately capturing my mood as I left the theatre. Shock, dismay, and anger would be more appropriate. Really? This is the best Indiana Jones film that can be made for $400 million dollars?

I didn’t really have high hopes even before I went to the cinema, but nobody prepared me for this. But, alas, I should have known right from the beginning when I saw the story credits included George Lucas. Somebody should really tell him that his scripts are terrible.

And he should listen up, and learn that CG of nuclear blast out in the desert, Communists chopping down the Amazon rain forests, aliens from somewhere other than Earth, and a big-name director are not suitable replacements for a well-written script. There was almost no redeeming value in this script, which I can only suggest is likely better to wrap up dead fish than to use in a high-talent action film.

Had it not been for the nostalgia of the original Indiana Jones movies, I would say this is the worst movie I’ve seen in a very long time; The Scorpion King, maybe, is still leading by a little bit. The most recent Star Wars movies are certainly in the running as well (and guess who was also involved in those scripts!) I think I see a pattern… It makes me wonder who really wrote the original Star Wars script.

In addition to George Lucas there is another name credited with the story. If I were Jeff Nathanson I would have asked to have my paycheck delivered to my house but my name dropped from the credits. David Koepp, the poor fellow credited with the screenplay, should have asked for similar treatment. Apparently the production went through eight writers, probably they just kept firing and hiring until they found someone who could tolerate working with the story as set out by Mr. Lucas.

This film was so cliche, so predictable, and so sloppy that it is possible that even Steven Spielberg must look back and think to himself “oh crap how did I get roped into this one.” Fire ants the size of grapefruits? The character Mutt swinging from trees like Tarzan? Mutt is the son of Henry Jones? Area 51 aliens? Shudder. Even a great director can’t fix a terrible script.

As you might have guessed, I won’t be picking up the Indiana Jones boxed DVD set for Christmas.

After ten or so days of serious investigation and debate, Eileen and I bought a new 2008 Nissan Altima today to replace the blue Saturn. We originally bought the Saturn off the showroom floor ten years ago and it had been a really good car, but we expected to replace it later this year. Having to buy a car on short notice made it much more difficult though. After careful consideration, the Altima was the right combination of features vs. price. We got the 2.5 litre SL package in a dark metallic grey exterior with a black leather interior.

The first car we drove was a 2009 Acura TSX and we found it to be a feature-rich car with excellent “sports sedan” appeal. A bit expensive though, for the features we really value.

The second car was a 2008 Infinity G35X. Wow. That car is amazing to drive. Fantastic handling, great engine (300+ hp) and sounds like a lion roaring when accelerating. The Bluetooth and iPod integration is the best I’ve ever seen in a car. Three things against it though: my head rubs against the ceiling, and it is thirsty for fuel, and it was well above our pain tolerance for price. Certainly the last one closed the deal there. I have no doubt that it is a great car, perhaps the best one we looked at, but we do have a budget to mind. Maybe in the future…

We also looked at pre-owned cars. I have nothing against a recent model pre-owned car but I never like buying privately (can’t be sure of what I’m getting) and dealer inventory is hit-or-miss. Since we didn’t have a lot of time our options were limited. We looked at a 2007 Lexus ES 350 and very seriously considered that car, right up until we realized that we aren’t (yet) Lexus people. Maybe our next car will be a Lexus: very plush, outstanding reputation and great finish. Hopefully people will think that of us if we are driving one!

We also looked at Volvo but discounted them due to lack of features at similar price points. Nice people, silly cars. I’m always reminded of that old movie line “They’re boxy but good!”

Another visit to the Infinity/Nissan dealer brought us to look at the Altima. I was initially skeptical but after a drive and a look at available options I changed my mind quickly. The 2.5 litre engine with the CVT transmission makes it quite responsive and we could get a huge list of features for a quite moderate price.

Another strong contender was the 2008 Volkswagen Passat. Eileen is driving a 2003 Volkswagen Beetle convertible and loves it, and our experience with the car and dealer has been excellent. However for the price was higher than the Altima for the similar features, so we just couldn’t bring ourselves to spend the extra money when it wasn’t necessary (e.g. the dealer isn’t that nice).

We spent a while driving around in the Altima today and we are thrilled to own one. I think we are off to a great relationship with that car, not the least because the Bluetooth phone integration with voice command is so much fun to play with!

I don’t think Eileen enjoyed the car shopping experience. I wouldn’t say I enjoyed it but it was moderately entertaining and we met some really nice people along the way.
