Could swap for a bit if you want to see the difference as it has the option of shiing in daytime, if you prefer that. Happy to pay the difference. Also DON'T SHORTEN THE WIRES!! Instead wrap the wire round your fork in a spiral to take up the slack, and pop a small tiewrap on the bottom to hold it in place. The connectors are a bit rubbish and I have had to cut the corroded ends off and take a bit off the insulation to bare clean wire when recrimping etc.... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10554#post-116156 Fri, 28 Jun 2013 09:47:59 +0000 kaputnik 116156@http://citycyclingedinburgh.info/bbpress/ <p>RE wheelbuilding I might try my hand at dynamo wheel for tourer.

Any time. Suspect by the time you get to yours I'll have built another two.

It has left/right off positions (centre is "on"), and generally only rattles when turned off in one direction and not the other. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10554#post-116122 Fri, 28 Jun 2013 00:03:49 +0000 Wilmington's Cow 116122@http://citycyclingedinburgh.info/bbpress/ <p>Connected up the lights tonight. The wires are a little... ugly, so might have to do some shortening and better routing, but all working fine (took a wee video, and the front especially is really bright!). Standlights working fine - the front light has an occasional rattle, which on inspection appears to be a little copper circle thing, but might be magnetic, because it stop every now and then and seems to stick to something - not explained that well, but the rattle disappeared as I trundled the street, so assuming it's doing whatever it's supposed to be doing.</p> <p>Also, I'm pretty sure I didn't order the front light that has the light sensor on it, so has a switch setting that means it won't come on during the day, but will automatically switch on at night. Certainly didn't pay for that, so I might have got a Brucie bonus there... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10554#post-115875 Wed, 26 Jun 2013 09:11:25 +0000 Wilmington's Cow 115875@http://citycyclingedinburgh.info/bbpress/ <p>Last night I put a picture of the 'cockpit' on Twitter, commenting that it was a little crowded. In reality there's room for it all, but there's the light mounted to the rack; the rack; the videocamera; bell; computer; and thumbie shifter. One comment was that it sort of ruined the 'chic' look of it. Which is true if that's what I was aiming for, but honestly, it's all just practicality mounted on there. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10554#post-115874 Wed, 26 Jun 2013 09:08:17 +0000 Wilmington's Cow 115874@http://citycyclingedinburgh.info/bbpress/ <p>Yeah, D90 is a little over 3 and been used and abused pretty much daily since then. Replacement planned for later in the year, but D90 will then likely remain as the bike/work/everyday cam.</p> <p>Rear brake has gone slightly 'squidgy' - sort that before riding home. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10554#post-115861 Wed, 26 Jun 2013 01:21:14 +0000 allebong 115861@http://citycyclingedinburgh.info/bbpress/ <p>I checked out this thread when it was first created with only a few replies. I come back now and we're talking about DSLR mirror vibrations and there's a picture of a bus seat. Let's keep this moving.</p> <p>Since you have a decent padded bag for the camera I'd stop worrying about it. My D90 is well traveled on both bike and foot and is none the worse for wear. In fact the thing has been downright abused at times, including plenty of drops and falls, and even an incident in which it fell into shallow water upside down and pretty much the whole upper half (viewfinder/top LCD) was flooded. Exactly how this happened and how much was my fault is a long and rambling tale best left for another time ;) That was two years ago and it's done tens of thousands of pictures since then with no ill effects. Except for some slow growing mould on the inside of the flash. Eww. </p> <p>I belong to the 'you can pry my optical viewfinder and mirror out of my cold dead DSLR-grip hands' camp with regards to mirrorless cameras. This makes me the photographic equivalent of a retro-grouch and I fully expect by the time I hit mid-age I will be reminiscing about the good old days of sensible steel frames, handbuilt wheels and phase detect autofocus sensors that weren't on the main sensor. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10554#post-115860 Wed, 26 Jun 2013 00:51:32 +0000 Wilmington's Cow 115860@http://citycyclingedinburgh.info/bbpress/ <p>Don't be daft, my saddle is 'real' leather... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10554#post-115842 Tue, 25 Jun 2013 21:10:09 +0000 kaputnik 115842@http://citycyclingedinburgh.info/bbpress/ <p><img src="http://farm7.staticflickr.com/6073/6103955017_2cbfd26e32.jpg"><br /> Just sayin'... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10554#post-115814 Tue, 25 Jun 2013 18:34:47 +0000 Wilmington's Cow 115814@http://citycyclingedinburgh.info/bbpress/ <p>Hey Stickman!

I've never quite figured out if that makes Nikons more or less susceptible to jarring/vibration damage, although in general my experience of Nikon cameras is that they are a tad heavier and more robust than Canon equilvalents, and much more bullet proof than Pentax/Fuji etc. </p> <p>Not just mirrors could be affected of course; cameras where the vibration reduction mechanism (ironically) is in-camera can come a cropper too. That said, the impact on lenses could be equally profound, but a little less easy to detect as images can degrade by degrees depending on the extent to which lens elements go out of alignment. Modern lens design is pretty good at minimising this, but not completely preventing it.</p> <p>FWIW, I've invested in a Lumix mirrorless system camera for bike expeditions. Image quality is not the same as my SLRs', but it ain't so far off and is certainly good enough for magazine and web use. And it is absurdly light, too. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10554#post-115730 Tue, 25 Jun 2013 09:51:32 +0000 DaveC 115730@http://citycyclingedinburgh.info/bbpress/ <p>DP. </p>
