Plantronics Blackwire C610

I occasionally have to work from home, and most of that work ends up involving long conference calls. I’ve taken to using VOIP for these calls, but until now I didn’t have a quality headset to use during such calls. I’d tried everything from speakerphone via my iMac‘s built-in audio to an iMic and old analog gaming headset, but nothing sounded good and was comfortable to wear for more than a few minutes.

Having used Plantronics headsets for years at work I decided to see what they offered for portable / computer use and came across the Blackwire C610, one of their enterprise products and purchased it from PROVANTAGE for just under $70 shipped.

Without loading any drivers or software this headset shows up as a standard mono USB audio device, and its inline volume and mute switch works independently of the computer. The mute button also beeps through the earpiece to indicate mute status, and illuminates a dim red when the mic is muted. The headset weights a bit less than the handset alternative headset that I’d used at work for the last nine years and comes with the typical cord clip. There is also a two ear version (the Blackwire C620) for those who don’t like one-ear headsets.

The headset comes with both foam and leatherette ear piece covers, and the sound quality is outstanding. In tests calling friends and on conference calls I’ve received no complaints about quality, and when specifically asked I’ve been told that it sounds better than any mobile phone I’ve used recently. (This probably also has a fair bit to do with the PCM codec used by my VOIP provider.)

Special Mud

This evening I met up with a coworker (Doug) and a friend (Jon) to ride the Lake Orion High School (LOHS) mountain bike trails. After running into the trail builder, M. C. Escher himself, in the parking lot and talking for a few we headed out. While brutal compared to most other local XC trails, the LOHS trails are in great shape and after a slow ride around there took connector trails into to Bald Mountain South Unit where we were able to ride the flowing, fast two track for a while before heading back to the parking lot.

Since we we weren’t in super-thick fog the new headlight worked wonderfully, and using both elements (spot and wide) it throws light far enough that I could comfortable ride at full speed. A bar light still would be nice to create some shadows, but I think this setup will serve me really well.

Back at the parking lot I noticed a bit more mud on my bike, which surprised me since the LOHS trail was dry and packed hard, and I didn’t recall any mud in Bald Mountain. Not thinking right I grabbed a pinch of the mud to see if it was actually just a different colored piece that landed on my bike last night I realized my mistake: it was not mud. This is not the first time I’ve ended up with trail feces on my bike, but normally I notice it before I touch it and can then wash it off later.

Thankfully the school was open for a band concert and I had some Dr. Bronner’s Peppermint Soap in the car, so I was able to visit the bathroom and wash the soiled hand (and a key) before changing. At least I managed to only contaminate one hand and a small metal object, and the doors to the school were propped open. The clump shown above in my fork crown is only the little bit that remained after the 1″ clump I’d originally removed with my fingers. That bit of filth ended up in the grass just before I tried to wipe my hands (somewhat) clean on the damp blades of green.

Riding with just a headlight generally eliminates shadows, as having the light nearly on-axis with your eyes keeps one from seeing shadows. Adding another light located elsewhere, such as down on the handlebars, creates just enough shadow on objects that it’s almost as easy as riding in daytime.

Pea Soup

A night ride in tonight’s pea soup fog was an interesting and challenging time to try out my new bike headlight. With two 700 lumen elements, one wide and one spot, and default settings of high power for one, the other, or both, the light was almost a bit too bright. I would like to have the headlight run a bit dimmer for the foggy conditions, but I’m quite confidant that the light will do what I want of it.

While the fog was often dense enough to obscure single track 30′ away and the humidity caused ones glasses to fog up at every stop, it was really pleasant to be out in it. I’ve been wanting to do a ride in fog for years and it did not disappoint. The entire ride was like swimming in a cool, damp blanket and every stop (once everyone in the group had turned off their lights) found us in a quieter than normal darkness without the normally visible distant lights. It was almost like riding in a snow storm but darker due to the lack of bright snow and without the cold. It was wonderful.

(The photo above shows the new headlight in spotlight-only mode with only one 700 lumen element running shining at a tree near my condo on a long exposure.)

NiteRider Pro 1400 Cable Keying Indicator Inconsistancies

Today I received a NiteRider Pro 1400 (more on this later), a new bike light for trail riding. NiteRider lights typically have a textured indicator on the connectors to make blind connections easier, such as when plugging in the light behind one’s head or while in the dark. When setting up this unit I noticed that the cables on the light and battery pack have this textured piece opposite the flat side of the connector, but the extension cable (so that the light can be helmet mounted) has it on the flat side of the connector.

This inconsistency means that when using the extension cable one has to be sure that one cable has the texture on one side and the other is the opposite. I’ve contacted NiteRider via their contact form and hopefully I’ll hear back from them soon.

Pictured on the left above is the extension cable, which has the textured keying indicator on the same side as the flat part of the keyed connector. The battery pack’s cable (on the right) and the light’s cable (not shown) has it on the left. It only seems logical to me that the keying indicator would be on the flat side which is opposite how the Pro 1400’s light and battery pack are set up. It’ll be interesting to see what NiteRider’s response is. Maybe this first run of Pro 1400s (it is a newer product, after all) have their keying indicators inadvertently backwards?

UPDATE: NiteRider has sent me the proper, and much better fitting cable as a replacement. Per Davilynn over at NiteRider:

Some of the systems were packaged with our older extension cords by mistake.

Not Yet A Bridge

Tonight’s ride showed me that the bridge being placed in Heritage Park, which will connect downtown Utica with some nice asphalt trails and allow for a safer crossing of VanDyke, isn’t in place yet. The pilings and approaches for it are nearly done and a crane is sitting and waiting, but the bridge itself apparently still needs to be delivered and set in place.

Per reports I’ve read online it’s slated for some time in November, so hopefully it’ll happen before the snow flies. This bridge allows for a very nice foot or bicycle route route from River Bends through Utica, then over to everything on the east side along Metro Parkway, including the new single track in Clinton River Park. While neither this nor River Bends are particularly challenging trails, they make for very nice, fun rides and a great place to go in evenings; particularly after dark.

The trails are in absolutely perfect shape right now, with the leaves gently breaking down over hard pack and leaving the trail route quite nicely visible. I was worried that River Bends would repeatedly become completely obscured by leaves, but it appears that a bit of raking right after the heaviest leaf falls has done the trick. Now I just need to wait for some vacation time (next week!) so that I can get out there and finish the seasonal loop. It’s almost ready, only needing some general clearing, line trimming, one segment reopened, and (maybe) a small bridge built over a creek down in the flood plane. Or the bridge could just not be built and I can recommend that people get better at bunny hops and/or cyclocross-style dismounts.

Home, to River Bends via some neighborhoods, one lap of the single track (including the seasonal loop), pavement after the single track, over to downtown Utica via Shelby/Cass, tunnel under M-59, to the unfinished bridge, back into the neighborhoods, into Heritage Park, tunnel under VanDyke, asphalt path through Clinton River Park, CRP single track, Schoenherr, 19 Mile, Hayes, 21 Mile, Milonas Drive, a bit of Heritage Place North, a lap around Heritage Place West, then back home. 25.55 miles, 1:55:17 moving time, 13.30 MPH moving average, 25.9 MPH max.

2010 Iceman Cometh Challenge

This weekend was the Iceman Cometh Challenge, an annual race that runs from downtown Kalkaska to Timber Ridge in Traverse City, and the first one in which I participated. I’m content with my time of 2:36:01, which included one intentional stop to use the forest as my urinal, and a few unintentional stops due to the trail being too congested to ride.

Just as I was told, the route is mostly fast two track with some good sized hills with a bit of single track sprinkled in. Due to the sheer number of people racing (3700 or so), their varying ability levels, and the flow of traffic there were a number of places where the route bottlenecked bad enough that one had to stop and wait for a few moments. With most of these places being on narrow uphills I found myself walking a handful of times, and even waiting for 15-20 seconds while one blockage cleared. The tight bits of single track were also ridden at a slow group ride pace. All of this made my time slower than I would have liked, but it also provided some forced resting and really is just part of the Iceman experience. I was told it would happen, so I wasn’t particularly frustrated by it.

With my start time of 10:28am (wave 28) being just below freezing (22°F – 28°F depending on the temperature device), the trail started becoming muddy about half-way through the course, right around the time that the hills started. Thankfully much of this was gritty northern Michigan sand mud that wasn’t too slimy, although the newly cut (so new it seemed to be just for the race) pieces of single track were nearly as bad as the Tree Farm Relay. However, due to the congestion there was no fast riding in them.

If you’d like to see some film of the trail check out this video shot using a GoPro camera mounted on the fork of Jeremiah Bishop‘s bike. It shows more of the fast two track sections and few of the climbs, but it does give a feel for the trail. (Hopefully the complete footage will make its way online eventually.)

Due to the size of the race riders are asked to park at one of the local schools, to which school buses and box trucks (for carrying bikes) make regular shuttle runs. While it’s possible to park along the road leading to the finish venue it’s absurdly crowded and difficult. As we’d planned Danielle parked at one of the schools, so after catching my breath post-race and eating some fruit leather I rode the ~3.5 miles from Timber Ridge to the car. It was then easy to change in the parking lot, store my bike in the car, and catch a bus back to the finish line for some food, beer, and meeting up with friends. After the day was done we then hopped on a return bus to the elementary school to get the car.

I intend to register for the race again next year, and hopefully the conditions will be either the same, or perhaps a bit warmer and without as much mud (or any rain). I love riding in freezing temperatures with a light bit of snow on the ground, so this didn’t disappoint, but I sure wouldn’t mind being able to wear shorts. The event itself is also quite well put on, with a nice expo at registration packet pickup the night before, well organized starting, a well marked course, and an outstanding finish venue with lots of reasonably priced local food, $4 pints of Michigan beer (Bell’s, Kuhnhenn, Shorts, and Right Brain), a changing area, free cookies / HEED / water, and plenty of good viewing of riders approaching the finish line.

The only difference next year might be that we’ll stay some place other than the Motel 6. It was cheap, reasonably comfortable, very well located, and the rooms were clean, but it could have used to have been a bit quieter and with Michigan-type humidity in the rooms. We both would wake up periodically from noises in the hall and other rooms, feeling a bit dehydrated from the furnace that just heated air and pumped it through a slightly rattle-y vent into the room.

Avid MatchMaker and SRAM X-9

After getting a good deal on a SRAM X-9 rear derailleur and shifter set I moved its X-7 parts to the Specialized while building the 69er. As part of fitting the X-9 stuff I also picked up a replacement set of brake/shift lever clamps known as Avid MatchMaker, which allow the brake and shift levers to share one mount. I think this makes for a cleaner looking bar, but due to its L shape it doesn’t save as much space as I thought and other items (such as a bell) can’t really be placed snugly against it.

When fitting the new rear derailleur I ran into a slight problem where the derailleur would sit slightly too far inboard, preventing the chain from sitting cleanly on the smallest cog. Even when the shift cable was removed and the appropriate set screw was backed all the way out the chain would rattle and jump up one cog. After using a DAG-2 confirming that the derailleur was straight the only solution was to move the derailleur slightly outboard with a washer. Conveniently my friend Jon gave me a 1.38mm thick 3/8″ zinc chromate-coated washer which did the job nicely and allows the bike to shift just as it should.

All of this work was coupled with some much-needed overall washing and drive train cleaning (and plastics replacement), so after getting everything back together I went out for a ride at Stony Creek. While this week was busy enough to keep me from being able to ride, I did manage to get out to Stony Creek this afternoon. A bit of tweaking of the shift cable was needed to get everything proper, but the bike otherwise seems to be working great. I had one possible moment of skipping during a hard climb, but in general the whole bike worked wonderfully. Coupling that with some wonderfully cool weather, absolutely wonderful trail conditions, and meeting a few nice folks while riding, it turned out to be a really great day.

Now I just need to give the bike another shakedown ride or three before Iceman Cometh Challenge next weekend.

SRAM Flak Jacket is UV Sensitive

Back when setting up my Titus Racer X 29er I fitted SRAM Flak Jacket cable housings, which include hollow red plastic tubes and nipples to cover the portions of cable which are normally exposed along the frame. Unfortunately this plastic tubing is quite UV sensitive and within a few months I began to notice it fading. During the summer my bike is frequently on the back of my car while at work, so it probably got a fair amount of direct sun exposure. Today when finishing the installation of some drivetrain components I touched the piece on the seat stay and felt it crack.

Pictured above is an original red piece of tubing and the broken one that I removed. The broken piece shows the light-colored top which was up on the bike and more exposed to the sun and the slightly redder bottom that sat against the frame. The the break shown occured when I simply wrapped my hand around the cable and seat stay and flipped the bike upside down to remove a wheel.

With such a bright color to the plastic I suspected this would happen, but thankfully the kit came with a fair bit more tubing than needed so I was able to replace the broken piece. I wish SRAM would have chosen a UV-resistant plastic instead of the bright red that they went with, perhaps the black nylon used in UV-resistant cable ties. I may try to find somewhere to buy other plastic that could be used in place of the red stuff, perhaps some PTFE or nylon…

Ceiling Fan Light Working Again

The ceiling fan in the bedroom has a remote control to turn it on and off. Over the past few weeks it’s become increasingly hard to turn it on and off, with the switch inside the remote feeling like its failing. Taking apart the remote tonight I found that instead of small tactile switches (like I thought it had from the feel) it instead has cheap, printed contact switches actuated by conductive rubber on the back-side of the buttons. As common with switches like this some of the rubber had worn off on to the PCB, fouling the copper and causing the buttons to not work well. A bit of quick work with a pencil eraser and alcohol-soaked paper towel cleaned the contacts up nicely and everything is working great again.

Click here to see a high-res version of the photo above, clearly showing the bits of rubber stuck on the PCB.
