2006 Honda Civic Navigation System GPS Data Viewing

Back in late 2005 when I purchased my current car, a 2006 Honda Civic EX, I found that the built-in navigation unit could record log files to a PC Card. Knowing nearly nothing about reverse engineering data files I gave up on the idea of using them for anything. Fast forward to a few months ago, and while poking around with GPSBabel for converting some mountain bike trail mapping data I noticed that it supports Honda/Acura Navigation System VP Log File Format (vpl), the format that I’d hoped to interpret all those years ago. The most basic, latitude/longitude parts of the format are documented here in vpl.cc.

This morning I dug out a 512MB compact flash card and PC Card adapter, fitted it in the navigation unit, and used the hidden menu to enable logging. After grabbing the log file and running it through GPSBabel the end result is just what I’d hoped for: easy logging of wherever my car happens to go.

While it’s not terribly interesting to see the routine, boring local trips that I make, I am interested in recording a month’s worth of data and making a heat map, or perhaps visualizing a long trip I may take. This’ll be fun to play with, I only wish I’d noticed the converter sooner.

Cutting Coroplast on a Table Saw

Some of the local mountain bike trails that I work on are in need of more signage, so a few months back I picked up a few sheets of Coroplast and a fellow CRAMBA-IMBA board member printed up some vinyl bicycle decals and directional arrows. This evening I finally got around to cutting the Coroplast, and after trying a few different methods I settled on using a table saw. While I only had a wood cutting blade I found that by using a fence and feeding at just the right speed I was able to make quick cuts and short work of producing 6″ x 4.5″ signs.

Now that this part is done I just have to get the decals applied distribute them as appropriate.

Footbeds and Shims for Specialized Pro MTB Shoes

After a couple rounds of toe numbness and pain on longer rides with my new Specialized Pro MTB shoes (3+ hours, and on 4+ hour hard rides with my older shoes) I stopped by Fraser Bicycle and Fitness intending to pick up a set of higher arch support footbeds. Chris Goddard happened to be there and he checked me over, gave me a bunch of great advise about things to try, and set me up with 2x 1.5mm varus shims for each foot,  blue/moderate support footbeds, and the suggestion that I move my cleats back. While I only had my old shoes with me, these were enough to get a good feel for what I should try.

Upon arriving home I immediately put the footbeds and shims in my new shoes, moved the cleats back a bit (maybe 7mm) and hopped on the trainer to try it out. While I only got in ~10 minutes of spinning, the shoes felt like they fit much better to my feet than they had before. I’m looking forward to a longer ride, but I now feel more like my feet are solidly planted in the shoes when I begin applying force, not that they press into place as I pedal. I hope this translates into even more comfort while riding.

I’m pretty happy on all of my bikes, but these new shoes had me a bit worried. Then with a bit of foot pain during a six-hour endurance race on Saturday using my old shoes, I got a bit more concerned… This seems like a good way forward.

In The Nick of Time

It’s a good thing that I decided to give the El Mariachi Ti a quick wash and a once-over before this Saturday’s race. I’d noticed some quirky shifting on the last couple of rides, and apparently this was the cause. I hadn’t planned on replacing the cable and housing this evening, but I was glad to do it now than angrily after dealing with a cable failure (and emergency single speed conversion) mid-race.

I’m really glad it didn’t let go on any of the other rides I’d done recently. I’d been noticing some issues with shifting near the top end of the cassette recently, but after recabling things those quirks seem gone and the bike is ready to ride.

Garmin Edge 510 ANT+ Recording Stopped at Lap

Here’s something odd that happened during a long ride with my Garmin Edge 510 (firmware 2.90). While stopped in River Bends Park to climb over a tree I pressed the Lap button to mark the location so the tree could be removed, but then after that point the unit stopped recording data from either of the ANT+ sensors. Both the HR and Cadence values seemed to be stuck at whatever they were when the Lap button was pressed.

Firmware update 3.00 is out and I’ll try updating to that and see if it comes back, but as the change history simply states “Changes for manufacturing.” I wouldn’t be surprised if it happens again.

UPDATE: A bit of research has shown that it wasn’t actually when the lap button was pressed. It just happens to be right after that.

Here is the first record of the consistent/wrong 142 BPM, 24 RPM data:

<trkpt lat="42.64555980" lon="-83.04996448">
    <ele>160.6</ele>
    <time>2014-05-04T21:32:47Z</time>
    <extensions>
        <gpxdata:hr>142</gpxdata:hr>
        <gpxdata:cadence>24</gpxdata:cadence>
    </extensions>
</trkpt>

Here’s the lap marker, which shows it was earlier:

<gpxdata:lap xmlns="http://www.cluetrust.com/XML/GPXDATA/1/0">
    <index>0</index>
    <startTime>2014-05-04T21:32:09Z</startTime>
</gpxdata:lap>

Close, but definitely earlier.

Carbon Fiber Shoes, Squishy Fork, Lubed Cassette

A rainy, quiet Saturday while Danielle is working gave me a nice opportunity to get some bike stuff done. In preparation for what I hope to be a long ride tomorrow and the Fun Promotions Stoney Creek 6 & 12 Hour Mountain Bike Endurance Race I removed the rigid fork from the El Mariachi Ti and put the original Fox and Arch EX-based wheel back on. While I like the high volume tire and rigid fork, it’s still a bit much for long rides. Thankfully the swap between forks and wheels is easy, taking only about 15 minutes. I imagine I’ll be switching this around a few times this year.

I also had to re-remedy a long-standing problem with the cassette on the El Mariachi Ti: it’s noisy. Last year I was dealing with some odd under-load ticking sounds that were worst mid-cassette and in the little chainring up front, especially when really mashing on the pedals. After a lot of experimentation I was eventually able to reproduce it and found it could be alleviated by lightly greasing the plastic spacers between the cogs. This seems to last for a few months, then it needs to be done again. This should go away once the cassette is replaced, unless the next one has a similar problem…

Finally, I got a pair of Specialized Pro MTB shoes set up and ready to use. At the end of last year I was able to pick them up on clearance at Cycletherapy, since they are the discontinued model with a strap closure, as reviewed here. These are very similar to the Comp model that I purchased in early 2011, except with more venting and a carbon fiber sole. Three years the Comp shoes were starting to get near the end of their usefulness, with holes appearing in the sides of the toes, the sole becoming more flexible than normal, and the insole seriously breaking down.

I appear to have the cleats positioned appropriately, although the pedal body on Eggbeaters seems to hit the lugs a bit. I’m not yet sure if this’ll cause a problem or is a good thing, but if it ends up not working I’ll have to shave a millimeter or two of rubber off of the lugs. Clipping in is a little stiffer than I’m accustomed to, but the solid shoe-against-pedal feeling makes for a very rigid interface. It should also move energy transfer to a larger area, cutting down on the pedal wing / shoe sole transfer that eats through Shoe Shields.

Trying the shoes out on the trainer and in the rain around the parking lot, they are definitely stiffer than the non-carbon fiber composite Comp shoes that I normally wear. They improve on the Comp shoes stiffness to the same degree that the Comp shoes (and my previous Sidis) improved on the Shimano SH-MT40 commuter shoes I’d first started out with. Fit is almost identical to the previous shoes, but with a new, stiff, less slipper-like feel. These should be good.

Ideas… Ideas…

Today is one of those days where I find myself with lots of ideas for things to do swirling around in my head. I just have to parse through them and figure out which ones are feasible, and when I can do them…

So, what am I thinking would be good to do? Here…

  • Take a half-day on Thursday and go ride Poto on a single speed before the Waterloo public meeting with the DNR.
  • Take a half-day on Friday to hike PLRA and gather more GIS data for mapping.
  • Order some wide, hookless carbon fiber rims from Light-Bicycle to build a new set for the El Mariachi Ti. Then sell the existing Arch EX wheels…
  • Hike River Bends and clean up any lingering deadfall. Maybe Saturday?
  • Attend the Stony Creek Trail Day.
  • Write up a new description for Massive Fallout.
  • Write up a document trying to convince more people involved in volunteering to work on MTB trail stuff.

Now, to find the time…

Defective REI Venturi Shorts (2014)

A few days back I picked up a pair of the REI Venturi shorts, as I needed more shorts and these were quite comfortable when tried on. I wore them for much of the day today and they were comfortable, but poorly engineered pockets is causing me to return them.

Upon arriving home from my parents’ Easter dinner, when reaching into my left pocket with my right hand to get my keys, I heard a tearing sound. It turns out that the thread used to stitch along the pockets is not as stretchy as the short material itself, and stretching the edge of the pocket causes the stitching to burst, as seen above. At $69.50/pair I expected better, and I’ll be returning these tomorrow. I’m disappointed in this because they are comfortable and met a need.

A Wish Fulfilled

Ever since beginning to do mountain bike trail work and seeing the effect of a heavy storm on trails I’d wanted to see this first hand. Today I saw this, and no longer wish to. JD Harvey and I were part-way through the more remote parts of some single track at Stony Creek when a hail storm arrived. Trees fell around us, an inch or two of 1-2cm hail fell in minutes, and we had to ride rough single track near-blinded to get out. This makes for a good story, but something that I do not wish to repeat.

Today’s weather was quite excellent, and after plans with Joy and Mark there was a bit of time, so I decided to go for a first-ride-of-the-season at Stony Creek on the El Mariachi Ti with the CroMoto Grande rigid fork. Not long after beginning the 6/12 Hour route I ran into JD riding his new fatbike, so he and I began riding together. After completing one lap we decided to start another, planning to part ways at the Swamp Cutout of the Roller Coaster so he could ride home to Rochester and me to the car. Not long after starting it seemed to be getting dark quickly, but we pressed on as we normally would have been out of the trails within fifteen minutes. Just before reaching the end of the Saturday/Sunday Reroute, within the span of 30 seconds a bit of rain spat, then the wind kicked up and hail began.

Unlike my usual experiences with hail and thunderstorms — where it lasts for a few moments before changing to torrential rain — this didn’t let up.

As we made our way to the climb to the Rest Area I called for us to stop and walk up the hill to save time, something which seemed to be over in a flash. Descending from the Rest Area to the Swamp Cutout was a haze as riding instinct took over. Whenever I’d look up from the trail I’d see branches and whole trees falling in what appeared to be a fog of painful ice. I fell briefly when rounding a small drop/corner (same places as here, five years earlier) due to my wheels rolling out from under me on the ball bearing-like ice, but save for interrupting our escape this was uneventful. Once getting down to the Swamp Cutout we found that the entire forest was covered in 1-2″ deep balls of quickly melting hail.

The usual route back to the parking lot, straight from marker 29 to 2 was blocked with an immense tree, so we turned back, detoured along the single track by marker 3. Between that point and the parking lot we had to climb over at least three more trees, and make a last-minute duck to avoid the neck-height wire which had fallen across the trail. I’m very fortunate this wasn’t a live power line, as I saw it just in time to duck, glancing my helmet off of it.

Once back at the car I quickly packed my bike inside, put JD’s on the rack, then got us both in the car with the heat turned on high. The photo above (and this one) were taken near the exit of the West Branch parking, as the hail began to melt. The river-like washes through the hail were exactly that: places where water was flowing down the pavement channeled through the ice. While packing the car this was flowing over my feet, something which I paid no mind as I was just happy to be out of the woods.

While this was quite an adventure, the worst storm I’ve been caught in, a good experience, a fulfilled wish, and something for good stories, I do not want to repeat it. We both were very fortunate that we didn’t get caught up in any of the falling trees, didn’t crash in a serious way, nor encounter any other catastrophe. Simply having wet/dirty bikes, some welts (I’ve got a large one on each forearm and a sore finger), and a story to tell show just how fortunate nature was with us. This shouldn’t be pushed a second time.
