Learned this test from a friend of mine Mr. Wail A. T. Tarabzouni. Here is how you can test your sensor.
use a lens that can give you f22.
here are the steps.
1. put lens to f22
2. aperature mode for normal expsoure
3. defocus the focus in manual focus mode.
4. any wall with uniform color. wave your camera around it during exposure.
as you can see i have lot of spots on the sensor. next step ill be learning how to get that cleaned.
.RAF conversion results (July 2012)
The Fuji sensor arrangement makes the conversion RAF to JPG challenging for everybody. I tested 3 applications but still have not found the “Holy Grail” of Fujifilm sensors.
Silkypix (provided): the images are soft, have a “blue” tone and can not solve the greens very well. The results are so mediocre that I thought it was a problem with the camera. Anyway colors are uniform and noise is undetectable so can be useful in some cases.
Lightroom 4: is a good compromise, not so sharp but not so noisy and plenty of controls. But you need to pay for it, learn to use it, and it is not the “official” converter. If you have it, use it.
Therapee 4: gives the sharper and noisier results, it is free and can give good results. The photo size is the same than in .RAF, which is smaller than 4000x3000. It is a good complement for Silkypix users.
JPG from the camera: results are the best and are not time consuming, but you have few controls over it and need to be preset. M size (6mp) is sharper than L size (12mp), Astia film and highlights in low are advisable too.
I wish some company develop a better product to convert these .RAF files easily and better, meanwhile I shoot JPG and for important events RAF + JPG, a big SD card is mandatory.
Good shoots and better conversions ;)

Saarloq es una localidad en la municipalidad de Kujalleq, al sur de Groenlandia, ubicado exactamente a 60°32′N 46°03′O, a unos 20 km de Qaqortoq. Tiene una población de 50 habitantes. (Wikipedia)
En el mar de Labrador, al sur de Groenlandia, se forman estas revueltas corrientes que parecen formar borrascas. Pero estas corrientes (de color azul intenso en la imagen) se hallan en la superficie del mar. Las nubes se ven en color blanco, como las que aparecen a la izquierda en la imagen. Este color azul representa zonas nevadas sobre tierra firme, como en las islas que se ven arriba y a la derecha en la imagen, donde se encuentra la citada localidad de Saarloq. Supongo que en el mar se trata de aguas muy frías, con temperaturas cercanas a la congelación.
Saarloq is a settlement in the Kujalleq municipality in southern Greenland. Its population was 21 in 2020. It is located on a small island with the same name off the Labrador Sea coast, at the mouth of the Qaqortoq Fjord, west of Alluitsup Paa and 20 km south of Qaqortoq.
The settlement is the southernmost of the three settlements—along Eqalugaarsuit and Qassimiut—that made up the former Qaqortoq municipality. The settlements are presently governed by a joint settlement council. (en.wikipedia.org/wiki/Saarloq)

A unos 320 km de su desembocadura se inicia el delta, que abarca una extensa zona de 14 100 km² entre las provincias argentinas de Buenos Aires y Entre Ríos. Tiene un ancho que varía entre los 18 y los 61 km y se caracteriza por el avance frontal debido a la extraordinaria cantidad de sedimentos que transporta. El delta está constituido por numerosas islas cruzadas por un sinnúmero de brazos, riachos y canales por los que se descarga al Río de la Plata el espectacular derrame de la cuenca del Paraná.

This is a very simple digital sound sensor (Arduino Sound Sensor Module for Sensor Shield, SKU 74446) from Goodluckbuy. It’s either triggered because there’s a sound loud enough or not. The sound level threshold can be set by adjusting the pot on the PCB and the red surface mounted LED can visually show you when the device is being triggered. Much like the light sensor an op-amp is used (LM393).
The only down side is I would have liked the choice of either a digital or an analogue value much like the light sensor and it’s switch.
Disused "Sensor Test Stand" decaying away in a military equipment junkyard in San Antonio, Texas.
The words "SENSOR TEST STAND" had been stenciled in the top left corner of this unit, and there was a word in front of it, but it had weathered to the point where I couldn't read it for certain, but I think it said "GASKET", which might make sense with the pressure gauges and what not on the unit.
Terrible composition, I know...but I was in a hurry, and this was a one-shot deal.
See an aerial view of this junkyard to get an idea of the size.

View large for the full horror.
I decided to clean my sensor last night.
I'd gotten a bit tired of cloning out the same dust spots from my photos taken over the last few months.
I use the Arctic Butterfly from Visible Dust to clean, I'd only used it once before but I was very impressed with it.
So, I took the lens off and set the camera to Sensor Cleaning mode.
After the first clean most of the dust had gone, but a few small smears had appeared.
I decided I'd better clean it again as smears would be a lot harder to clone out than the odd spot.
I did it again, put the lens back on, took a test shot and nearly died - I'd somehow managed to seriously gunge up my sensor.
I cleaned it about 3 times more and it still wouldn't go away.
I then decided to do some googling around to see what online advice I could find.
Micheal Reichmann's site is actually the number one hit for "Arctic Butterfly" on Google, and it contains this gem:
"7: If there is a stubborn particle, note where in the frame it is, and then with the shutter open in cleaning mode, shine a flashlight into the mirror housing at an oblique angle. You should be able to see it. Just remember that the location will be upside down from where you saw it on the monitor.
8: Try using the Butterfly again, this time concentrating on the spot. If this doesn't work, you'll need more sophisticated cleaning tools, such as the swabs and fluids available from VisibleDust."
Following the advice I brushed the sensor back and forth on the problem spots, which were easily visible.
I then re-attached the lens, took the test shot and hey presto, clean!
Not sure what I did wrong to get all that gunk on there, I just hope I can go another 6 months or so without having to clean it again.
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.
