2009/08/28 Trackmaster
π 2009-08-28 20:00 by Ralf in Android
At the track, I played a bit with Trackmaster on an Android phone and recorded some tracks and lap times.

Trackmaster is quite easy to use: simply create some split points using a maps overview (so make sure to do that when you have a fast network available, e.g. in advance at home over WiFi). Then you start it and it starts recording as soon as the first split point is reached.

Since I did not have a good mount for the phone, I just kept in my pocket. Worked fine.

There's a lot of data to look at and export after the fact:

2009/08/28 TEAM Racing at Thunderhill
π 2009-08-28 00:00 by Ralf in Trackday
I went back to Thunderhill with TEAM Racing this time. The event went really smooth, without an itch, and I'm already looking forward going back for the next event in October.

The list of participants was on the smaller side -- around 30 total with 15 in the novice group.

My dedicated instructor was Mike Meier, driving a black Prelude. That was nice since we had comparable cars although of course he had better mods and most important, he really knows how to drive. He was giving me plenty of feedback and tips on getting the right line. I had a great time with him and I hope to meet him again next time.

In preparation to the track day, I had changed my brake pads and brake fluid (Axxis Ultimate and ATE Typ200) with the help from http://www.xperformance.com and that worked wonder. However I can now feel when I reach the limit of the tires (the default Michelin MXM4 that came with the Civic) so next time I'll try to upgrade that -- which is good since I need new tires anyway now :-)

Here are the pictures that Dito Milian from GotBlueMilk took at the event:

This time I borrowed a Canon SX200 IS from Eugenia. I recorded a couple of sessions and extracted these 3 laps. Lap times are 2:38, 2:36 and 2:38 respectively:

Here are a few more images I took, first of the paddock:

The novice group is having a download meeting after a session:

Believe it or not, there is a playground! It doesn't seem to be used much:

2009/08/12 Reviews
π 2009-08-12 00:00 by Ralf in Rants
I've been writing some Amazon product reviews recently, so I though I'd share.

Let's be honest: I love Amazon, first because they have a web site that does not suck and that is full of useful features. Once you've used them, all other e-commerce sites look disappointing.

The next best thing is when I became a prime customer. Sure, prime is not free, but if you factor the shipping price you'd pay, it all makes sense. Sometimes an item price will be a bit more expensive than elsewhere, but the resulting price after shipping and handling might be better on Amazon. And you get it in two days. No brainer.

There's something cool also about getting a UPS truck deliver stuff to you in the middle of a forest where there is no postal service delivery. It's faster than going to the nearest town -- although the DoItBest hardware store of Dallas, PA is nothing to be ashamed of and can be quite competitive.

So anyway, I thought for the fun I'd put here a selection of my reviews. It's quite a wide range.

KeyTronic 104 Key PS2 keyboard

This is a KeyTronic full-size PC keyboard. It's one of the best things you can attach to a computer.

If you do a lot of typing, that's the kind of keyboard you need: it has a nice feeling, the spacing and the layout is just fine, and contrary to laptop-like keyboards there's some real depth to the keys.

Contrary to some modern keyboards, like the Microsoft "ergonomic" one, all the keys work the same, even the space bar. You won't have a key that feels different or gets stuck because of bad plastic. They have all a similar pressure and feedback and all make a wonderful noise when pressed. You can type lightly or literally pound on it and it will work the same.

Note that this series of KeyTronic keyboards is a quite noisy. That's part of the product. If you want a silent keyboard, move along. It's not as noisy as the old IBM pounding-metal keyboards from the 80's or 90's, though.

It's durable too. My last KeyTronic lasted 10+ years before one of the keys started acting up from time to time. There's supposedly a lifetime warranty on it, but let's face it, after 10 years or so it's cheaper to get a brand new one than get the membrane replaced. It's also trivial to open it and service it yourself, if you're so inclined.

Tool House 770002 52 Piece Metric and Fractional Bit Tip and Socket Wrench Set

That's a nice thing to keep around for a great cheap price.

The case is convenient but it doesn't qualify of "durable". One of the closing tabs of the case broke when I tried to open it the very first time. It comes with a tiny piece of foam inside, which keeps everything in place, yet still when I hold the case vertically things tend to shift and move inside. Mere details -- you're not buying this for the case, are you? The case is just here to help put it away and avoid loosing all these pieces :-)

The two ratchets are nice and feel sturdy enough. The yellow screwdriver is quite narrow and lacks grip. There's a nice number of sockets, covering a whole lot of ranges. The sockets are good fits and I have yet to break or ruin one.

Overall it's nice to have this around, handy and at that price you don't have to be too careful.

Fiskars Chopping Axe 23.5-Inch #7857

This is a rather good axe and it's nice to use. I used it as a felling axe to clear some paths in the forest.

I used it to replace a very very old steel-head axe with a hickory handle (the head kept coming off and I don't have the tools to hang it again.) Being new it was nice and sharp, didn't get stuck too much. It was a bit shorter than I expected -- my old axe was a 25- or 26-inch, so 24 seemed a tad short whereas 28-inch seemed too long. Going from a hickory handle to synthetic, the feeling is not the same when it hits, it gave a much harsher feeling in my arms. It was also a tad lighter than my old axe. Fine, I had to adjust a bit, I got over it and the result is that I cut some hard old wood faster than before and it was a lot of fun.

Motorola T9500XLR 25-Mile 2-Way Radio Pair

I got these radios to keep a safety contact when I'm nearby in the forest, with hills and of course lots of trees in between. The effective range was about 2 miles in this condition, which was good enough for me. The radios are light to carry, they come with a handy belt clip. There's a dock for easy recharging. Using it was rather easy and intuitive, although the menu key that has several functions seem a bit confusing at first -- just adjust all settings with the manual in hand and then don't touch them again :-)

I'm not sure how long the battery lasts: I've used it for whole mornings or whole afternoons mostly sitting there on standby with maybe a few minutes worth of chat and it took several days like this for the battery indicator to get down to 2/3rd. It's a NiMH battery so it *will* have aging issues after a few years but by the time they start loosing their charge it will be more economical to simply buy a new set than replace the batteries.

I do give it 4-star instead of 5 just because of the "iVox" hands-free feature: I just couldn't get it to work and the manual is not too helpful on that one. I kept setting the mode on, then later when I'd try to use it nothing would happen and I'd realize the iVox mode had gone off in between. I'm dubious of the utility of that mode anyway, so it doesn't really matter.

If there's one feature I miss: I wish the radio would also display the current time. Like that I could skip carrying a watch. But then most people probably don't care about that :-)

Sony MDR-NC40 Noise Canceling Headphone

Overall these are good headphones. I use them when I travel, mostly to cancel airplane noise. If you've never used cancellation headphones, they are great to remove constant background noise, so in a plane that means you can better listen to your music/movie without having to put the volume insanely high. Note that noise cancellation does not cancel voice chatter, so don't even try to use this in an office -- in this case you want over-the-ear cups for good isolation.

They fold easily but folding the whole thing in the accompanying case takes a bit of practice and patience at first. It's a tight squeeze but I now manage to store my iPod nano in the case too. It then stores easily and it is pretty light to carry around.

Otherwise they are OK comfort-wise, just a tiny bit tighter on the ear than my older Sony noise canceling headphones. Sound-wise, the bass is a bit too much boosted even for my taste; a bit of equalization on the iPod fixes that easily.

Panasonic BL-C131A Network Camera Wireless 802.11

Overall this is a good camera. Setting it up with my wifi was trivial. Price is a bit steep but you get a quality product with good support, for once. I found a few limitations, your mileage may vary:

  • I wish the lens was a wider angle; the field of view is 49° (according to specs), which is standard but I've been spoiled by my Logitech Notebook Pro webcam with a 70° wide angle.
  • I wish the horizontal motion also had a wider angle. The exact pan angle is described in the spec as 100°, so a tad more than a quarter of a turn. Given the protruding design, I think they could protrude it a tad more and go all the way to 180°, that would be really nice.
  • You really need Internet Explorer to use the full capabilities, audio and video. I used IE7. I prefer to use Chrome or Firefox but in this case the video works in MJPEG mode, with no sound. I also successfully used "IP Cam Viewer" on my Android phone to connect to the camera using my wifi, at least for the video (here again there is no audio).
  • MIU Connoisseur Corkscrew

    This is a really good "rabbit" like wine opener. If you've never used one, you'll be impressed the first time you use it. Not only is it faster but it is also more reliable and it's hard to break a cork with such an opener, even an old cork. That's a gift that will keep on being appreciated.

    Price is really good and quality is on par. I generally use it once a week and I have no problem with the corkscrew. The screw itself is replaceable and I have yet to use the replacement after several years of use. The foil cutter broke after several months, but that can be easily replaced -- or just use a knife to remove the foil, as it is customary to do.

    Sleep Better 3-Inch Visco Elastic Memory Foam Mattress

    We have this on our queen bed, which mattress was good but now feels a bit too hard to our aging backs and has saggy spots. This foam topper fixes both issues, as is to be expected. The 3-inch is a good size and it's a pleasure to sleep -- or more appropriately "to sink" -- in it every night. At 2.5 lb/ft^3, the density is medium, which is good enough.

    The foam arrived rolled in a big box. It was not as compressed as I thought -- some reviews make you think it's compressed in a dark hole and then will expand to fill your whole house... it's not that dramatic!

    However the smell of new foam toppers is a known issue -- all foams I've seen do that anyway, it's not just that one. The original smell is not only nauseating, it gives me immediate headaches. I can't stress that enough: you must let the mattress air and expand in a *ventilated* non-living area for at least 2 or 3 days before using it. Don't rush it -- in case of doubt, let it air one more day rather than be deceived by the chemical smell, as it will be nauseating at first. Put it somewhere out of sight in a ventilated area, such as in the basement or the garage. If after 3 days you can stick your nose on it and not feel the urge to run away fast, then you can consider moving it in the bedroom.

    After a month or so of use, there's still a slight curious smell the first time I'd get in bed, but nothing dramatic. It's such a pleasure to fall asleep and wake up on that thing, it's totally worth it.

    2009/08/06 I know what I did last summer
    π 2009-08-06 00:00 by Ralf in Rants
    Outside. Nice green forest. The beaver was gone. Everything was as I left it last year.

    So instead I found an old axe and used it to clear the old trees fallen on the paths. By old axe I mean in good condition yet 2 generations behind; and although the head was of really good quality it kept coming off the handle. A practical ax expert would just tell you you have to know how to hang your own handle to the ax head.

    Although that sounded attractive for about a microsecond or two, I just got myself a brand new Fiskars Chopping Axe which was really so much more efficient yet shorter and lighter. I got the 23.5-inch one, which is the closest to the old 25-inch one I had been using. It's a tad short, but the only other choice is a 28-inch, which is really too long.

    I also had some fun with the Craftsman Lawn Mower 917.288700 and did some maintenance on it, simple stuff like changing the oil and all the oil/gas/air filters.

    The older Craftsman Tractor 917.256544 was out of commission but after removing the mower and adding a new battery that now makes a working tractor and I can attach it to my dumping cart.

    The other thing I did was explore the 250 or so acres of forest, trying to match the deed description (in perch and rod units, no less) and I ended up with some nice tracks on Google Earth.

    My main tool was mostly MyTracks, to record the tracks and upload them to Google Earth but eventually I also ended up writing my own Android Bearing app to compute the compass bearing between two marked points.

    It's the first time I actually play with a GPS. On one hand it was nice as it actually worked fairly well it the medium-dense forest; on the other hand the precision wasn't that impressive -- the GPS generally indicated 8 or 16 meters for accuracy but it did not update fast enough when walking. Also the integrated compass on the phone was incredibly noisy with the reading typically fluctuating -/+ 10 degrees.

    Finally I got quite a lot more done, including many many hours spent reading the vast content of TV Tropes, working on my Android apps ([Bearing|] obviously, but Timeriffic, Brighteriffic and Flashlight got translated to French too and had many other improvements, without even mentionning Nerdkill) and much more.

    Overall what made the biggest difference was having a real 24-hour almost-instant internet connection instead of a 33K modem line. In that regard, I must say the ARC booster antenna was incredibly good when combined with the aging Kyocera KPC650. Bandwidth ranged from 70/40 KB/s (down/up) down to 3 KB/s (in rain at night, it's really that weather sensitive) with a typical average speed of 15 KB/s when I was generally getting no signal at all without the booster antenna. I guess being in the middle of a forest, behind a hill and out of the official zone coverage doesn't help :-) The signal strength indicator was around -100 dBm without the antenna and up to -80 dBm with it.
