The AS-10 220V 10A Automatic On Off Light-Based Photocell Sensor Switch is an intelligent lighting control device designed to automate the operation of lights based on ambient light levels. This sensor switch utilizes photocell technology to detect changes in natural light and trigger the activation or deactivation of connected lighting fixtures accordingly.  The AS-10 photocell sensor switch automatically turns lights on at dusk or when ambient light levels decrease to a certain threshold, and turns them off at dawn or when light levels rise above the set threshold. This automation eliminates the need for manual operation, providing convenience and energy savings. The sensor switch is rated for 220V AC voltage and can handle a maximum current of 10A, making it suitable for a wide range of lighting applications, including residential, commercial, and outdoor lighting systems. The switch's sensitive photocell sensor allows it to precisely identify variations in the amount of ambient light. When the photocell detects a change in light intensity, it activates the switch that regulates the linked lighting fixtures. With the AS-10 sensor switch's customizable sensitivity settings, customers can alter the activation and deactivation levels to suit their own lighting needs. Its adaptability guarantees top performance in different lighting conditions.

Zeaker by David Buckley and Colne Robotics, Practical Electronics, May & June 1983. The name 'Zeaker' is a contraction of ZX-81 and Seeker, as it was designed to be controlled from a Sinclair ZX-81 fitted with an I/O expansion card. Zeaker was available as a kit from Colne Robotics of East Twickenham, UK.

"ZEAKER is a small, low cost computer controlled robot vehicle designed to have all the normal functions of a "turtle" i.e. steering, lights, pen, horn and bump sensors but it is also capable of being expanded using photosensors for eyes to seek out or avoid light or to follow white lines etc; with a complex sound generator for special noises à la R2D2, and with computer speech. It will easily interface to most popular microcomputers and can be programmed in a high level language like BASIC, although a modular language like FORTH or PASCAL would be better. Under program control Zeaker can go forward, backwards or rotate right or left on the spot; it has two navigation lamps: port and starboard (or eyes if you prefer) which can be turned on or off; a speaker which can emit a high or low tone or a combination of both; 6 tactile sensors which can detect a collision with an object in Zeaker's path and finally but not least a pen which can be lowered or raised to enable Zeaker to draw Turtle Graphics. The up or down state of the pen is indicated by a lamp on the top of Zeaker." – David Buckley, Practical Electronics.

It was confirmed that the eco-friendly quantum dot photonic sensor developed through joint research with Professor Moon-kee Choi's research team at the Department of New Materials Engineering, Ulsan National Institute of Science and Technology (UNIST) and Professor Dae-hyeong Kim's research team at the Department of Chemical and Biomolecular Engineering, Seoul National University (President Hong-lim Ryu) can stably measure light signals without any external power source, due to the photovoltaic effect. The joint research team has also produced a skin-attachable ultra-thin pulse sensor based on this photosensor, and introduced the wearable pulse sensor that can stably acquire pulse signals despite different deformations. The work is published in the journal ACS Nano.

If you poke a TV-mimic's 'screen', is it hard like glass or soft like human skin? Or is it somewhere in between, like the turgidity of an eyeball?

If it's hard, is it covered in a hard layer (like the big clear scales covering snakes' eyes) with squish underneath?

TV mimic "screens" are like skin in a way, like the rest of their body! The chromatophores that exist underneath the skin-like material is what makes their false screen change colors, express their emotions, and allows them the ability to see!

Apologies for the rushed diagram, as mimic biology is a little more complex than this simple drawing, but it is to help explain this biological aspect. The outer layer of their visors are a little hard but flexible! It almost feels like a very clear fingernail or chitin. It protects the insides from debris, injuries, and UV rays. The cell layer is where most of the magic happens! This is how their expressions, color, and visuals change! These purple spots are clumps of photosensors and chromatophores that change and alter themselves when the surrounding nerves and flesh are stimulated with certain hormones, such as cortisol (stress hormone) or endorphins (happy hormones). They can change shape in milliseconds, allowing for the mimic to express themselves fluidly, as if they had normal face expressions. This layer is usually surrounded in a type of jelly that simulates optic fluid, to both protect the nerves and to maintain the optic system. They both see and express out of the main "screen". The nerve layer is where the signals are transferred from the brain (not pictured) to the cell layer, which then reflects on the outer layer! These optical nerves are sensitive to light, chemicals, signals, and stimulus. These nerves are also extremely reactive and are very responsive to said stimuli, which encourages change in the cell layer. This innermost layer is connected to the brain of the mimic and also functions as the mimic's optic nerves deep inside of their chassis. Injury to this layer can lead to blindness, deafness, or even cognitive or abstract processing problems. This layer is deep and defended to help prevent these issues. These layers allow the mimic to have vision, expressions, and even signal communications! This is why they are very important to TV mimics!

fascinating, new dual-pixel autofocus architecture that can do cross-type focusing. This is on the new Canon R1. This has long been a weak point for dual-pixel autofocus over dedicated focus sensors.

New research explores durability of 2D hybrid materials

New research has unveiled the fatigue resistance of 2D hybrid materials. These materials, known for their low cost and high performance, have long-held promise across semiconductor fields. However, their durability under cyclic loading conditions remained a mystery—until now. Led by Dr. Qing Tu, professor in the Department of Materials Science and Engineering at Texas A&M University, this is the first study of fatigue behavior on the semiconductor material called 2D hybrid organic-inorganic perovskites (HOIPs) in practical applications. Researchers recently published their findings in Advanced Science. This new generation of semiconductors holds great potential in nearly the whole spectra of semiconductor applications, including photovoltaics, light-emitting diodes and photosensors, among others. The application of repeated or fluctuating stresses below the material's strength, known as fatigue loading, often leads to failure in 2D hybrid materials. However, the fatigue properties of these materials have remained elusive despite their widespread use in various applications.

The last week, my brain has decided to respond to my "please for the love of God stop my brain and knock me the fuck out" medicine by going into manic work mode instead.

I've gone to sleep 2 hours later than I'm supposed to all week, but I have made excellent progress on designing a specific use-case photosensor for a project I'm planning. It has also caused the part of my brain that wrote an operating system back in college to come out of hibernation, so that's cool.

The thing neurotypicals tend not to understand about the ADHD brain is that it really only has two gears

I turn to the chalkboard and carefully write out

lumogarnets my beloved

heres a few lumogarnets and facts about them:

chromium doped YAG gems, sometimes called 'Christmas garnet'

some green LuAG gems

and my personal favorite. GAGG

All of these are called lumogarnets because of their strong flourescence. When under UV, blue, or sometimes even indoor lighting, they will flourece a ton.

Christmas garnet is a type of YAG (Yttrium Aluminum Garnet) doped with chromium. this causes it itself to be green but flouresces red under most lighting conditions. giving a strange festive play of color.

LuAG (Lutetium Aluminum Garnet) is yet another lumogarnet. this one flouresces a neon green, and in fact, is one of the brighter lumogarnets.

And finally, my favorite lumogarnet GAGG (Gadolinium Aluminum Gallium Garnet) is a very interesting lumogarnet, as it has many strange properties. It is paramagnetic, strongly florescent, phosphorescent, and is one of the brightest lumogarnets.

Lumogarnets main use is in radiology. They convert incoming X-ray radiation into visible light that can then be captured using film or photosensors.

They are also used in lasers, but I don't quite know how they work in them.

sorry about rambling on about these cool rocks. I'm just very passionate about them

Man made crystals are so cool it’s so sad everyone who likes rocks is out for blood if you post man made crystals. I love you opalite I love you lab created opal I love you bismuth I love you HTA citrine I love you goldstone

Scorpion (1983) by Harprit Sandhu, Bob Syeszycki and Foad Rekabi, University of Illinois, for Rhino Robots Inc., Champaign, Il. The Scorpion is a robotic terminal, designed to follow instructions and return data sent over an RS-232 link. It’s based on the 6502 microprocessor with two software controllable 6522 Versatile Interface Adapters. Sensors include a pair of downward facing photo-reflectors enabling it to follow a tape on the ground, and it has bump sensors on each of its four sides. The most unusual feature is a two-axis optical dish, with a single photocell at its focal point. This dish can be scanned vertically and horizontally with a resolution of 1.5 degrees per step. "Conventional vision systems are too expensive. What if we could build an optical scanner that scanned the environment, collected the information, and displayed the information on the video screen? A display of 40 characters by 25 lines would produce 1000 pixels of varying brightness. This should be sufficient for recognizing many simple objects. We could experiment with pattern recognition, perform calculations to enhance contrast, and find edges. To gather this information, a cadmium/sulfide (CdS) photosensor is mounted at the focal point of a solar cigarette lighter." – The Scorpion Software Overview, by Harprit Sandhu, Robotics Age, January, February, March 1984.
