Energizer Trailfinder headlamp

I’ve been experimenting with using Energizer’s “Trailfinder” headlamps. I generally haven’t had much luck attaching hiking headlamps to my bike helmet — the sloped helmets I use makes the elastic strap just slip up and off — but I’ve managed to figure out a couple of tricks.

The first trick is to secure the strap by running a small piece of tape or a zip tie through a vent hole to hold the strap in place. That’s what my son used during our bike trip last May to Sacramento.

Because the Energizer Trailfinder light can flip up, I was also able to run the strap around the back of the helmet and put the light flat on top, like so:

Inexpensive light

At the rear of the helmet, the strap runs near the back retention straps and doesn’t seem to interfere with the helmet fit.

Another helpful feature of the Energizer Trailfinder: It has a pair of red LEDs in addition to the white LEDs!

Something like this is handy if you’re caught out later than expected without bike lights and all of the local bike shops are closed. These kinds of lights are available at any outdoor retailer and many drugstores and mass market retailers.

This is mostly a hiking / camping light. The Trailfinder will leave this weekend for a 10 day backpacking trip through the Sangre de Cristo Range so we’ll see how it holds up under harsher conditions. For urban bicycling, the light stays on and the white and red lights are both reasonably bright. Unlike most bike lights, the Trailfinder only has “steady on” modes — there are no flash or blink modes for this light.

If you use hiking headlights for your night time bicycling, I’d love to learn your tips and tricks.

Odds and ends

I’ve been biking to work since the 80s, and I have bike parts laying around all over the place. Sitting on my desk at work I have a 1986 Shimano 105 brake lever waiting to be put to use somewhere.

Likewise, I have an inbox of bikey links to share, some older than others. Enjoy!

Mission Bicycle in San Francisco started as a side venture in 2008 selling fixed gear bicycles online. They decided to open a retail presence on Valencia in SF. Read more.

California Highway Patrol incident feed for bicycles

I’ve whipped up a script that takes the California Highway Patrol live traffic incident data feed from the 20 CHP dispatch centers around the state and filters for anything mentioning bikes or bicycles. You can see the results here.

At the time I’m writing this post, there’s a single incident between Woodland and Davis, CA: a bicyclist riding in the number 1 lane on State Route 113 just south of County Road 25A is reported to be a traffic hazard. “1097 in the CD” means the responding officer is parked in the center divider. I have no idea if bikes are permitted on this state highway or not.

Location: SB SR113 JSO CR25A, Woodland – 7/30/2009 9:46:53 AM
1125 – Traffic Hazard
  &nbsp — 9:56AM 1097 IN THE CD
  &nbsp — 9:47AM BICYCLIST RIDING IN THE NBR 1 LN

Right now, this is a rough proof of concept, which means:

  • I grab the incidents as they’re available on the CHP server.
  • No caching of incidents, by me or anybody else.
  • No permanent links of incident reports.
  • When the incident ages out on the CHP dispatch center it is gone forever.
  • Good probability of false positives. You’ll see reports of motorcycles and anything mentioning “bike lane.” I doubt I’ll change this heuristic much.
  • You need to decode the terse radio codes and abbreviations yourself. I may work this decoding into the application.

To make this truly useful, I need to:

  • Poll the CHP server automatically every 10 minutes or so and spit the results out to Twitter, an XML feed, or to email.
  • Cache the incidents and;
  • Provide permanent links to the incident information.

I can do all of these things; I just need to be sufficiently motivated and make time to do these things. Please let me know if this would be interesting / useful for you, and feel free also to leave any kind of suggestion and opportunity for improvement.

Update: I’ve modified the script so it can take a query string so you can input your own search criteria. Examples:

Santa Cruz: Yes to Tour of California

The Santa Cruz city council voted yesterday in favor of signing a “host city agreement” for the Tour of California 2010.

Last week, the city manager added Tour of California host city preparations to a list of items to cut because of budget issues. Cycling enthusiasts sent letters and showed up to the council meeting showing their support for the event.
