First results of the new line sensor TSL1401CL 128 pixels at 400 dpi resolution. This signal show the piek level of the green laser on a white surface reflection. The signal is here is saturated due to the white surface.The intergration time is 47.5 us and the scan time is 70 usec. Even on a black surface the signal is about 1V. The readout of the analog signals are done by 2 ADC convertors type ADS7885 here at 32 MHz clock. The line sensor is more sensive compared to the previous version TSL202R at 200 dpi.
For the optic see:
All soldered together, working, and sealed up in a nice box. Now just to write software to do something interesting with it.
A map of the pentax autofocus sensors. Contrary to what the indications in the viewfinder, these sensors are not points but are T and L shaped on the sides and a cross in the middle. Only the 9 points in the middle are cross sensors.
Une carte des zone d'autofocus. Contrairement à ce que le viseur laisse supposer les "points" d'autofocus ne sont pas des points mais des L et T sur les bords et une croix au milieux. Seuls les 9 points du milieu sont de type "croisé" (ils détectent un contraste aussi bien vertical qu'horizontal).
Researchers at Pacific Northwest National Laboratory are conducting photo-induced gas-sensing studies to learn about the detection of gases. Shown, a small size vacuum sensor.

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.
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.

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.
what you should know that is not in the picture:
- object distance @ X10 is appx. +50% @ D70
- perspective is not equal
- sensor ISO is max'd out at full resolution (3200 @ X10, 1600 @ D70)
please consider this just another comparison, for what it's worth

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!

The 12-bit FlexSmart Analog Input Module for use with the H22-001 Energy Logger handles two single-ended input channels with user-configurable ranges of 0 to 20mA DC or 0 to 20 V DC which is suitable for 2.5-, 5-, and 10-volt sensors. Field wiring is 2- or 3-wire via screw terminals.
this was an unplanned attack. i was ordering up my 3rd pomegranate mojito of the evening (a triple play, if you will), and you-know-who-you-are meddled with my self-timer on my camera (which, p.s. i had just learned how to operate myself), and voila! candid selfie, in mid-order. the reason i'm inside with my sunnies, is because we had just been chased indoors from the patio by sudden wind gust and torrential rain. or perhaps you were able to discern that by the condition of my hair? :-)
i have no idea what's going on with the grainy lines (my brother tells me "it's the sensor"... don't know if he meant the camera, or me). but regardless, it does seem obvious something is amiss. neither here nor there. i used some type of sepia-like processing (honestly, i lost track... i was trying to salvage this somehow... and fiddled like nero to get rid of the lines... to no avail. but somehow, suddenly, this is what i got instead. i'm going with it.

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 :)

A close-up view of the light sensor employed by the phase detection autofocus system in the DSLR camera I took apart after its shutter failed. The horizontal and vertical rows of dark rectangles are the light-sensitive elements. Horizontal rows detect vertical edges in the scene, and vertical rows detect horizontal edges.
The 5 mm scale bar drawn at the bottom of the frame shows the size of the sensor chip. The resolution of the 4k version of this photo is about 3 µm per pixel.
