These are the two nylon-bristled brushes I bought for cleaning the sensor of my Canon EOS1D digital SLR. I think they only cost a couple of quid each from a local art shop. The key feature is the nylon bristles - the idea is to get them to pick up the muck by giving them a small static charge, then as you wipe the brush across the sensor, the muck is attracted to the brush instead. Give the brush a good blast of air again afterwards to blow the muck back off. View the full-size image to read the text on the handles.

Se observa que la apertura del obturador (procedente de una cámara full-frame, la R9... de película) deja ver la circuitería que rodea la matriz de fotodetectores, lo que causa a veces curiosos fenómenos...
The Bottom Bracket Torque Sensor outputs a voltage signal. The signal and the pedal force is linear proportional. Pedal force increases every 10kg, 0.15V voltage changed. The detectable maximum pedal force is 60kg. The input signals into sine wave with the crank angle. The outputs in 0° and 180° are zero. Maximum output is in 90° and 270°. Each rotation of 11.25°, the Bottom Bracket Torque Sensor outputs a speed signal. The shaft rotates a circle with 32 speed signal output.
Product advantages
The advantages include faster start and quicker response. No more temperature drift issue with high reliability in low temperature. Compatibility with standard bottom brackets, more easy to install and flexible length options, custom dimension and compatible with mid-drive motor.

Picture taken as a teenager at Zandvoort: the start of the last GP at Zandvoort, as seen from the Esso VIP box in F1's ultimate turbo year.
Digitisation was done by projecting the original slide directly onto a Nikon D200's image sensor, before the overexposed picture was further processed using Adobe Lightroom. The photo was originally taken by a Konica FS-1 analogue SLR camera.
Congratulations to Me :D

Pressure Sensor is used for measuring pressure of gases and liquids by generating a signal as a function of the pressure imposed. That is high accuracy and is built in over current protection circuit and reverse power polarity protection circuit. Pressure Sensor has zero point adjustment function and Peak and Bottom hold display and can be used to measure other variables such as fluid/ gas flow, speed, water level, and altitude and for controlling and monitoring in thousands of everyday applications. - www.atcomaart.com/pd/70525452705370495152/pressure-transd...
This was created for Flaghead Photographic at a recent Triggersmart seminar. The PIR sensor picks up on moving heat signatures so we dropped warmed up vegetables into a nice Thai bowl to demonstrate this function as we couldn't get a wild animal into the studio!
There's a blog about the seminar here - www.dephotographic.com/blog/triggersmart-workshop-decembe...
An MCA Cat III Workboat, owned by Aspect Land & Hydrographic Surveys Ltd, of Ayrshire.
The 'Marine Sensor' is road towable, and with a small forward cabin, can deploy from a slipway or boat hoist / crane and able to operate a wide variety of sensors.
Her hulls and catamaran configuration lend a fast transit speed and give good directional stability resulting in high quality survey data.

The sensor wand from BARS (Benthic and Resistivity Sensors) in the vent. A temperature of ~325 Celsius was recorded.
Look what I got in the mail today. An Analog Devices ADXL320 accelerometer (+/- 5grams). I also got 5 big green leds (10mm) that are extra bright. These will go underneath the monome. Now all that is left is a sheet of teak veneer.
After a replacement Heath/Zenith 5411-A motion sensor failed the same way (bad design) the first one did in a porch light (would only turn on in test mode), I decided to use a Regent motion sensor instead. This involved making an adapter between the Regent box and the Heath ball-and-socket swivel, which fits in a standard hole in an exterior electrical box (good design).
I needed to use the putty knife to get past all the plastic snap-tabs on the Regent unit (bad design).
These guys from the University of Louisville make water sensors (http://makerfaire.com/pub/e/4015). I thought about telling them to try the Bernoulli effect, but why? I noted they were using TI MSP430 microcontrollers.
Salvaged from a broken olympus E510. The image sensor is mounted on a frame that can move on both X and Y axis to compensate the common camera shaking.
The cleaned sensor after about 60 Eclipse E2 fluid and Mesoft lint texture swappings.

Ahh! What's this thing on my head!!! Oh, a sensor to calculate body core temp and circadian rhythm. Phew. Credit: Chris Hadfield Twitter account
Sensor dust before cleaning, only the two very obvious spots (dot lower right and hair lower left) showed up at other apetures in blue skies and such. To make the sensor dust more clear I upped contrast a lot.
After years of putting up with dust spots, which show up as ugly grey smudges on photos of nice blue skies, I cleaned the sensor on my Nikon D70. It took quite a few goes as you can see. Each of the photos here is an out-of-focus picture of a blank white computer screen which has then had its contrast increased hugely (by doing "auto contrast" on it) to make the dust spots show up better. The little round spots are dust. The other variations and the larger, slightly dark areas are tiny variations in intensity of the LCD computer monitor which have been exaggerated by the 'auto contrast" step.
I noticed several spots on my pictures I took during my vacation, especially the ones with blue sky. Here's what the sensor looked like before I cleaned it.
Taken at F 32, 1 sec close-up exposure of my computer monitor on a full white screen, then adjusted level in photoshop to reveal the dust marks.
