I am trying my sensor in my arm for the first time. It hurts a little but I suspect that will go away soon.
My circuit is almost complete, so measuring where my RGB LED strips need to come off the circuit, the stripboard will be cut down and where/how the barometric sensor will be attached on outside of skirt via a small piece of stripboard attached by flywires.
Picture taken at 50mm f:22, over a white roof. PP whit Camera Raw to show dust spot more crearly.
The picture was flipped to show the sensor as seen from the lens bayonet in a way to make easier the clean up.
Some very big spot on the right center side.
Featuring a new glass lens design in a hearty IP67 housing, Balluff introduces the new BOS 50K series family of photoelectric sensors. With an impressive 2m sensing range, this background suppression sensor and its highly-visible red light emitter is simple to set up and adjust, and it can detect objects regardless of color. It is a superior choice for installations where laser sensors may cause safety concerns or perform poorly due to contaminants in the air.
This is the smallest aperture that my camera can go. It looks pretty OK but to be pedantic, yes the dust kinda shows up. I don't think I'll be working with this aperture anyway becoz of the diffraction issue
31 Aug 2023, 05:22 UTC, Stuart Florida USA. Celestron CPC1100 HD telescope at f/14 (no Barlow). ZWO ASI224MC camera, 8 bit, bin 2, exposure 1s, gain 46, best 30 of 118 frames, no calibration frames, no filter, no guiding, no ADC, sensor 33.6°C/92.5°F. Good focus. Sky was not steady, scope appeared at least roughly collimated.
Note: Image was deliberately blurred in post-processing to show residual color (vice oversaturated white) on the disc of Uranus.
from Stellarium:
Altitude: 38°
Magnitude: 5.8
Apparent diameter: 3.6 arcsec
Processing notes: AS!3 and Photoshop.
Clouds: partly cloudy
Seeing: average

From Sky & Telescope magazine:
Uranus, magnitude 5.7 in Aries, is nice and high by midnight, 7° or 8° east of Jupiter.
from Wikipedia
Uranus is the seventh planet from the Sun and is a gaseous cyan ice giant . Most of the planet is made out of water, ammonia, and methane in a supercritical phase of matter which in astronomy is called 'ice' or volatiles . The planet's atmosphere has a complex layered cloud structure and has the lowest minimum temperature of 49 K (−224 °C; −371 °F) of all Solar System planets. It has a marked axial tilt of 97.8° with a retrograde rotation rate of 17 hours. In an 84 Earth-years orbital period around the Sun, its poles get around 42 years of continuous sunlight followed by 42 years of continuous darkness.
Uranus has the third-largest diameter and fourth-largest mass among Solar System planets. Based on current models, inside its volatile mantle layer is a rocky core surrounded by a thick hydrogen and helium atmosphere. Trace amounts of hydrocarbons (thought to be produced via hydrolysis) and carbon monoxide along with carbon dioxide (thought to have been from comets ) have been detected in the upper atmosphere. There are many unexplained climate phenomena in its atmosphere, such as peak wind speed of 900 km/h (560 mph), polar cap variations, and erratic cloud formation. It also has a very low internal heat compared to other giant planets, which is still unexplained.
Like the other giant planets Uranus has a ring system, orbiting natural satellites, and a magnetosphere. Its ring system is extremely dark refelecting only about 2% of the incident light and contains the known 13 inner moons. Further out are the five larger major moons: Miranda, Ariel, Umbriel, Titania, and Oberon. Orbiting at much greater distance from Uranus are the nine known irregular moons . The planet's magnetosphere is asymmetric and contains many charged particles which may cause the darkening of its rings and moons.
Uranus is visible to the naked eye. It is very dim and was not classified as a planet until 1781, when it was first observed by William Herschel . About seven decades after its discovery, consensus was reached that the planet be named from the Greek god Uranus (Ouranos), one of the Greek primordial deities. As of 2023, it was visited up close only once -- in 1986 the Voyager 2 probe flew by the planet. Though it can be resolved and observed by current telescopes, there is much desire to revisit the planet, as shown by Planetary Science Decadal Survey 's decision to make the proposed Uranus Orbiter and Probe mission a top priority in the 2023-2032 survey.
This project explores the “secret” life of hotels through different people from different nationalities and play with the mystical atmosphere of an “abandoned” building . Each hotel room sees many users going through its doors. Although taking place in the same room, the individual experiences and feeling of these temporary residents can be extremely varied and colourful.
I created a sound, olfactive and visual piece of artwork for the show.
I used recordings of interviews of people, from various background and nationalities. I asked each person a simple question: “Can you tell me the story of an experience you had in an hotel room”.
I chose one of the empty hotel rooms and played the people stories in there.
I projected cut outs shadows of a room furnitures and hanged a glass bottom for each story, in there was a smeel related to the story beeing told.
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 ¡¡¡
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.

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.
