I knew the sensor on my 40D was dirty but damn I had no idea it was that bad! Good thing I have a new set of dust-aid cleaners on the way.

Creo que tengo el sensor lleno de polvo, ah no son pajaros ¡¡¡
I think that i have the sensor full of dust, oh no they are birds ¡¡¡

One thing I found with the nikon D300 and now with my D700 is that the built in sensor cleaning function is pretty useless.
First of all, the camera comes out of the box with the cleaning option set to off by default... c'mon Nikon! ... I now have it set to clean the sensor when I switch on and off.
Well, it's taken about 1800 shutter activations and several outdoor lens changes... I finally got a spot showing on moderate apertures.
I've cleaned my other camera sensors plenty of times but I always get nervous with a new camera. I used Eclipse E2 solution and pec pads taped to a spatula - a used digipad swab [see note below]. But now I have a full frame sensor I thought I'd try 'Just - 24mm Sensor Cleaning Swabs' from warehouseexpress.co.uk. I'm impressed with them, they are individually sealed and have about the right amount of bendiness for want of a better word.
The top frame shows the spot before cleaning. The second frame the spot is gone but some dust has been distributed elsewhere on the frame - this is pretty standard. Finally, most dust is gone, a few spots near the edge but nothing that will affect my shoots this weekend. Ignore the blotchy look, that's the white paper and digital noise I guess. I have increased the black level a lot to enhance the spots - this enhances blotchiness.
I think I might change my process next time, I might use a narrow spatula with a pec pad taped to it for the edge and a 24mm spatula for a final sweep... or the other way around... hmm. Either way, the 24mm spatula only just fits through the shutter. Maybe the next size down will work better.
Incidentally, anyone reading this thinking of cleaning their sensor for the first time should read about it online. Read about the Copperhill Method, sensor brushes [I don't bother with them] and others before you try it :D The forums are a bit mixed, there are a lot of people who make recommendations and actually have no idea themselves so it's hard to get good advice there - but trawl through them anyway.
*about digipads - I used a spatula from a digipad with a pec pad taped around it for my D300 cleaning process. The digipads - as they came out of the bag - were rubbish. They come with material attached like most cleaning pads, but they left more dust on the sensor then they removed. Maybe I had a bad batch, I dunno.
Simple LED circuit, driven by 9V battery. My next goal is to replace the power supply with a USB cable, and build a mounting system.
Trying to reverse engineer how toy sword circuits detect a swing motion and do not trigger for a tilt motion, using only two cheap tilt switches installed perpendicular to each other. Am going to place some tilt sensors on a board in various orientations, wire them to LEDs, and swing the board while watching the blinking LEDs for a pattern.
Before I do this experiment, my hypothesis follows: Software loop detects state change on tilt_sensor1 and starts a timer. Timer will count down to zero then stop, setting a flag. If tilt_sensor1 state changes again, the timer is restarted.
If software loop detects a state change on tilt_sensor2 AND the timer flag is cleared (timer is running), then swing is detected.
Timer length will be adjusted for sensitivity.

PBOT moved that little signal sensor character over just a bit so that oncoming bike traffic didn't clash with people waiting at its old location.
The Sensor Tag - the protective tab that prevents the battery from being connected to the tag is not removed yet.
Sensor Dust of DEATH. Seriously, this is just shameful.
I just got the Giotto Hurricane Blower - it did absolutely NOTHING (ok, it got rid of two out of 500 spots, and really cleaned a lot of dust out of my computer, but other than that, nothing).
Excuse me while I go cry.
Tips, hints, and calming words are welcome.

At the end of most photo shoots (when I remember) I take a picture of the blue sky at f/22 or f/32. In this case there was quite of bit of dust that had collected on the sensor - it's much more noticeable on larger sizes of this image. Time to clean it. :) I should note that these dust spots are not that noticeable because 1) I usually shoot at f/2.8 or so which makes them much less noticeable, and 2) I usually shoot images with complex backgrounds rather than a blue sky or other flat color.

It is just for show, if you look closely the connector is not connected to anything. The sensor glove has ten sensors (5x bend, 5x touch).
