Got sensor cleaning brushes from visible dust (reviewed here). got rid of most of the crap (compare top and bottom) although in some cases it just added different crap or moved existing crap around. cleaned it about 10 times instead of the recommended 2x. unfortunately one of the brushes ships in a plastic envelope which has adhesive placed such that it's hard to remove the brush without contacting it with the adhesive. I think that's what added the smear in the upper left part of the frame. Fortunately the company offers a liquid cleaning product to get rid of smears created by the brush-poorly designed envelope product.
Researcher Rachit Mohan with his sensor readout chip made in 40nm CMOS, operating with a time-based technique.
Timing signals for the new detector system for the next 3D unit (2013) with 2 external fast 6 ms shutters. I would like to calculate the optimal position as well as the direction of flight. Detector calculation need to be super fast, into less then 50us. The readout of the 128 analog pixels from the sensor + high-speed ADC 8 bits convertion may take a max of 40 us, +60 us for position-direction calculation (10.000 calculations per second). This is a start of my dream, the special components have been delivered. Given the new components, the majority are implanted in SMD. This is an additional difficulty, only single-layer PCB is available at this moment. The line-sensor is true hole 14 pins version, all others are SMD.
Discussion can also be followed on the next Dutch forum:

Now I will start the verilog code programming for the FPGA board. PLL clock at 50 MHz is running, now I have to add all the other signals. Line sensor readout and the serial ADC convertion need to be perfect synchroon as show in the diagram. Change the value of the PLL clock to a lower value may vari the readout and acquisition duration of the sensor/adc convertor. Easy to adjust this integration times.
Update 2012 Aug 06
Timing adjusted and corrected for read out to the FPGA module. The read out time is only half of the past because of the use of two ADC 7888 highspeed converters.
The NEW HOBOnet Field Monitoring System from Onset provides a cost-effective and scalable solution for web-enabled monitoring of field conditions for applications such as crop management, research, and greenhouse operations.
Onset's wireless sensors are ready to deploy and easily link to the network, and data is accessed through the new version of HOBOlink®, Onset's innovative cloud-based software platform.
Key Advantages
• Lowest cost-per-measurement point
• Wide coverage with wireless mesh technology that can communicate through vegetation
• Scalable, with up to 50 wireless sensors streaming back to a central, cloud-based weather station
• Remote access to data and current conditions with a customizable dashboard for analysis
• Alarm notifications when conditions reach user-set thresholds
All soldered together, working, and sealed up in a nice box. Now just to write software to do something interesting with it.
IR sensor voor Fischertechnik kogelbaan. De IR sensor kan werken op 5V en op 9V. Hij is niet gevoeilig voor omgevings licht. Zelfs getest in volle zon blijft hij correct werken. Het stroomverbruik door de IR diode is ongeveer 9mA en de load voor de Phototransistor is 5 mA. Burst van kogels worden mooi verwerkt. Ook getest met de TXT Controller Fischertechnik en 9V voeding.

Pacific Northwest National Laboratory scientists have developed an electronic sensor fish that is designed to record some of the environmental conditions fish may encounter while passing through hydropower turbines. The original six-inch rubbery fish (pictured) has since been revised into the form of a 3.6-inch plastic tube.

This is the same image as seen in www.flickr.com/photos/samfeinstein/476181751/ but I have applied the unsharp mask. It did not seem to work out when I applied it to both sides at the same time, so I applied it to each side in different proportions. Click on farm3.static.flickr.com/2345/1928154854_dd5dfccf21_o.jpg to evaluate the effect. After you click on the link, you will have to mouse over the image to get a magnifying glass icon. Click while holding the magnifying glass over the image and you will be able to view it full size. Toggle back and forth between the original size of both images to see how the unsharp mask improves the image. Even with sharpening, there is no comparison between the 10 MP SLR and 10 MP P&S cameras.

Image sensor as picture object to test the resolution. The fine structure is ideal for measurements in sharpness of the reverse lenses.
I found the sensor type number on the chip:
Image sensor CCD KC73129
• Number of Total Pixels: 537(H) ´ 597(V)
• Number of Effective Pixels: 500(H) ´ 582(V)
• Chip Size: 6.00mm(H) ´ 5.10mm(V)
• Unit Pixel Size: 9.80um(H) ´ 6.30um(V)
MOC: Sensor GTR. The rear end turned out well, I think, with the Ferrari-like taillights, the exhaust pipes (it's the first time I've tried that technique, but it won't be the last) and the engine cover.
SENSOR, 12. yüzyılda özbek islam aliminin ilkkez yaptığı bir aletin uyarlamasıdır. Sorulan olumlu sorulara cevap vermekte olup, yurt içi ve yurt dışından bir çok bilim adamının sensorle ilgili yaptığı görüşler neticesinde, aura ya da quantum enerjisiyle çalıştığı ve sorulan sorulara olumlu yada olumsuz olarak cevap verdiği tespit edilmiştir.
This is the new temperature sensor w/ power indicator LED, and a new connector interface (RJ45 + backup .100 headers.)

This is the ACC (Automatic Climate Control) Sensor from my car. That circuit board used to be broken, so my ACC didn't work right. Fortunately I was able to tune it up. I super-glued the circuit board back together, for structural reasons, and then I soldered a jumper onto the thermometer (Thing that looks like a resistor) and now I have ACC again!
Ordered a new genuine Bosch O2 Lambda sensor (pre cat) as these need replacing every 250.000km and my current mileage is about 313.000km.
I noticed that my long term fuel trim (ltft) was bit high on the highway (about 10%), which is way to high. During normal coasting it sits about at 6%.
Checked the ltft again today and it sits at 3% which is a lot better. Mission success :)

Connection in series
Application: AND logic.
Distribution box with 4 and 8 sockets;
with built-in signal amplifier, to connect sensors in series (AND circuit) and recover any voltage drop.
Advantages:
- Led by each M8 socket shows if the signal is on or off.
- It is possible to connect in series sensors with high voltage drop as well.
- Connection of many sensors up to the cabinet by a simple M12 connector with 3 or 4 wires.
- It is possible to connect many sensors to a single PLC input.
One of the sensors being developed by the Yoon Group using light wavelengths to target specific regions of the brain.

MOC: Sensor GTR. A variation of the theme from my previous Supercar - I wanted to see if I could build something a supercar that looked a bit more like it was meant for the road than for the track. Very happy with the result.
