The new Balluff MICROmote® optical precision tube sensors are designed to detect free-floating air bubbles in transparent liquids. These free-floating air bubbles have dimensions smaller than their tube's inner diameter.
Entry for the preliminary round of Bio-Cup 2024
Theme: Space
With this build being my first Bio-Cup entry, I challenged myself to use as few traditional system elements as possible while still aiming to cover gaps smooth out harsh transitions using Technic and Bionicle elements (there are only 10 system elements in the whole model, can you spot them all?). This was a great opportunity to dig into my Bionicle part inventory and experiment with parts from the original run of the series as well as the CCBS parts used in the Bionicle revival and other constraction themes. CCBS and the older Bionicle elements have very distinct design languages from one another, so I tried to balance my use of both kinds of elements to get a mix of the smooth, sleek shapes and curves of the more modern CCBS while retaining the iconic mechanical and organic textures of the older Bionicle elements.
The final model has the right amount of bulk to appear substantial while still leaving lots of room for articulation and posing, and I’m very happy with how the CCBS armoring fills in the gaps left by the Bionicle limbs while still revealing their texture and mechanical detail.

The Perseus cluster (Abell 426) is a cluster of galaxies in the constellation Perseus. It has a recession speed of 5,366 km/s and a diameter of 863′. It is one of the most massive objects in the known universe, containing thousands of galaxies immersed in a vast cloud of multimillion-degree gas.
The Perseus galaxy cluster is the brightest cluster in the sky when observed in the X-ray band.
The cluster contains the radio source 3C 84 that is currently blowing bubbles of relativistic plasma into the core of the cluster. These are seen as holes in an X-ray image of the cluster, as they push away the X-ray emitting gas. They are known as radio bubbles, because they appear as emitters of radio waves due to the relativistic particles in the bubble. The galaxy NGC 1275 is located at the centre of the cluster, where the X-ray emission is brightest.
The first detection of X-ray emission from the Perseus cluster (astronomical designation Per XR-1) occurred during an Aerobee rocket flight on March 1, 1970. The X-ray source may be associated with NGC 1275 (Per A, 3C 84), and was reported in 1971. If the source is NGC 1275, then Lx is about 4 x 1045 ergs/s. More detailed observations from Uhuru confirmed the earlier detection and its source within the Perseus cluster.
In 2003, a team of astronomers led by Andrew Fabian at Cambridge University discovered one of the deepest notes ever detected, after 53 hours of Chandra observations. No human will actually hear the note, because its time period between oscillations is 9.6 million years, which is 57 octaves below the keys in the middle of a piano. The sound waves appear to be generated by the inflation of bubbles of relativistic plasma by the central active galactic nucleus in NGC 1275. The bubbles are visible as ripples in the X-ray band since the X-ray brightness of the intracluster medium that fills the cluster is strongly dependent on the density of the plasma. In May 2022, NASA reported the sonification (converting astronomical data associated with pressure waves into sound) of the black hole at the center of the Perseus galaxy cluster.
A similar case also happens in the nearby Virgo Cluster, generated by an even larger supermassive black hole in the galaxy Messier 87, also detected by Chandra. Like the former, no human will hear the note. The tone is variable, and even lower than those generated by NGC 1275, from 56 octaves below middle C on minor eruptions, to as low as 59 octaves below middle C on major eruptions.
So I had a sleep study that I was involved in. Had to use a C-PAP machine. Let me tell you, this night SUCKED!! Since I couldn't sleep, this was the picture I snapped with my blackberry. It's just my index finger in a sensor I had. Never again I tell you. NEVER AGAIN!!!

I picked up a second time my old Konica-Minolta Dynax 5D (an APS-C DSLR see details below) for an extra tour of the warm-humid tropical green houses at the Botanical Garden of Lyon, France.
This time I fitted to the camera its dedicated macro lens Sigma 1:2.8 DG f=50mm (equivalent to 75mm full-frame 24X36 format) . For this tour, I used a CF card 16GB giving almost unlimited number of possible RAW files (1694 !) .
I also used a fix 200 ISO sensor sensitivity. I had in mind to limit the session to 36 images as a regular 35mm film cartridge, but I finally did about 60 … The lens was equipped with a generic Anti-UV protective 55mm filter and its original Sigma shade hood.
Whenever necessary in low-light conditions, I used the build-in small flashlight (NG 12 at 100 ISO) to complement the ambient light and to restore vivid colors. The camera was used either in the manual « M » mode or the aperture-priority « A » automated mode.

After the session, the RAW files were transferred to the computer using a USB multi-memory cards reader and processed in the latest version of Adode Lightroom Classic (LrC version 14.1.1) that uses the external module Adobe Camera Raw version 17.0.1 for the RAW files development. The files were then processed as usual using the regular functions of Lightroom. They are presented either as printed files with frame or the full-size JPEG's.
About the camera :
I bought my Konica-Minolta Dynax 5D (an APS-C DSLR see details below) brand-new in the winter 2005-2006 after using intensively a Minolta Dimage 7 that was a futuristic early mirrorless digital camera. I got the camera as a bundle kit including a AF DT Zoom 18-70 mm / f3.5-5.6 (D) lens, a tele zoom lens AF 75-300 mm / f4.5-5.6 (D) lens, and a very nice macro lens Sigma 1:2.8 f=50mm DG that I used principally for documenting small horological objects.
The Konica Minolta Dynax 5D is a Digital SLR camera announced by Konica Minolta on July 15, 2005. It is also known as Maxxum 5D in the USA and (Alpha) αSweet Digital in Japan. It became available from September 2005 and was bundled with the AF DT Zoom 18-70 mm / f4.5-5.6 (D) lens.
The camera features a 6 megapixel CCD sensor. Image files are created at a maximum resolution of 3008 x 2000 pixels and recorded in JPEG (STD, Fine, EX-fine), RAW and RAW+JPEG formats. It uses CompactFlash for storage. The back has a 115,000 2.5" TFT color display.
Main differences between the 7D and the 5D are:
* Less buttons and dials
* Fibre plastic body, as opposed to a magnesium alloy on the 7D, camera is almost 200 g lighter (970g in workin order with the AF DT Zoom 18-70 mm)
* White balance bracketing
* Newly added colour modes, including black and white
The Konica-Minolta was the last DSLR camera engineering before the cession to Sony of the whole photo camera activities of the company.
I believe this is just a placebo, this button does not effect the traffic lights in any perceivable way.

Here I'm disconnecting the sensor plug (near my left hand). I'm not actually sure if you need to unplug it to remove the sensor, but it sounded good at the time.
