Alternative cables for GPS?

08 October 2021 - 06:19 PM

I picked up a Columbus nGPS receiver on eBay a few days ago. So far as I can tell it's very similar to the official Nikon version, and seems to work well. The only problem I've noticed is presumably a problem with the Nikon version too - I'm using it on a D7000 where it plugs into a socket on the left side of the camera, which is covered by a little rubber door (there's an alternative cable for cameras that have the round multi-pin socket on the front). The plug that goes into the camera is about 1.5cm long, and the cable itself is fairly thick and inflexible. This means that when the GPS is fitted I have the socket cover and the cable sticking out quite a bit. It feels a bit odd and obstructive at the moment, but I suppose I'll get used to it once I've used it more. I'm just a little worried that it'll catch on things or break the socket on the camera if I catch it on something.


What I was wondering is if anyone makes a more flexible version of this cable - ideally one that sticks out a lot less and is a bit more flexible so that there's less chance of damaging things. The socket on the GPS is a standard USB Mini-B type, not entirely sure what the socket on the camera is - I think it's non-standard.


I've attached some small photos to make the situation a little clearer.


Any ideas?

Partial Eclipse 10th June 21

10 June 2021 - 01:04 PM

London got glimpses of this through fairly heavy clouds - I managed to take a few pictures from a little before noon onward, using my D7000 and 100-500mm Vivitar zoom with a piece of reflective mylar to filter out enough light to keep things safe-ish.


Pictures are here




Here's the first one, reduced in size a bit, to give you an idea of what they're mostly like.



28-100mm flange repair

27 May 2021 - 11:23 AM

Is it at all possible to get replacement flanges for older Nikon AF lenses that still have the worm drive (AF rather than AF-s)? I picked up a job lot of lenses that includes a 28-100mm G in nice condition except that the flanges are mostly broken - there's a small bit of one and a really tiny bit of another, the rest are gone. It still works if you hold it in place so I'd really like to get it fixed.


The problem is that all of the replacement flanges on offer on eBay are for AF-s lenses - they don't have the hole for the worm drive and presumably there are other differences. I'm very tempted to try to make the flanges from epoxy glue, but I'd really hate to rely on that sort of bodge holding together forever.


Anyone know if there's a way to get hold of them - do Nikon still do spares for lenses that old?

Thermal Imaging

12 March 2021 - 07:54 PM

For my birthday I treated myself to a basic thermal imaging camera, the FLIR One, a little module which plugs into an iPhone. It takes a lowish-resolution thermal image (60x80) and superimposes the colour onto a 480x600 visible light image. It finally turned up earlier this week and I've been amusing myself with some fairly simple photography. A couple of examples:


View from the back of my flat (the white blob in the sky is the sun)




Heat plume above a candle flame




Plant on a window sill with cold glass




I'm still learning its capabilities, eventually I want to try stitching images etc. At the moment I don't think I'll eventually be going for higher resolution gear, but it's interested me enough that I'll be keeping it. An album here, I will probably be adding more in due course:




Anyone else using this technology?

More problems with classifieds

25 February 2021 - 01:59 PM

I'm probably the person who posts more to classifieds than anyone else. And I'll be honest, it's so difficult to use this part of the site - starting with the insistence that dollars are the only form of currency that exists, which is not helpful for a seller in the UK - that I'm thinking about giving up on it.


The latest thing is the need to add an image to every ad, which will soon get through the space made available for uploads. I assume that this has been done to deter spammers, and that there's some way to delete images from it. but if so it doesn't seem to be obvious. For example, a couple of weeks ago I tried to sell a couple of F55 bodies and uploaded an image. They didn't sell on eBay, so I want to rewrite the listing. But will it let me re-edit the listing after two weeks, or reuse that image (accessed via "my media") as the compulsory image in another ad? Of course not. So the only way to do it will be to copy the thing and upload it again, eating another 350k of storage space. Except that I'm going to start making images much smaller to eke out the remaining space, which probably wasn't the intention.


So my immediate question - is there a way to delete images from "my media"? And in the longer haul, can something be done to make classifieds little less complicated and fix some of the problems?
