This is one of the 6 boxes with a speaker playind its part of a sound montage, leds that light up to the sound intensity, a light sensitive resistor (in the light bulb) that when covered reveals music, and an infrared range sensor (the eyes) that detects people and mangles the sound appropriately. The (sharp) infrared sensors are read by ladyadas wonderful ADIO board and the light sensors are read by an arduino and the information is thansmitted via MIDI to a computer that sits in the central brain and sends the audio back to the the respective modules.
These modules are a big as my travel trailer! These were dropped off in an open lot across from the cotton gin, probably because the gin was busy and there were already trucks lined up waiting to unload.

Pyroelectric sensor is a kind of sensor, also known as human body infrared sensor, used for life burglar alarm, visitor notification, etc., the principle is to release the charge through the amplifier into a voltage output.
The piezoelectric ceramic dielectric can maintain a polarization state after being polarized, which is called spontaneous polarization. Spontaneous polarization decreases with increasing temperature and the temperature drops to zero at the Curie point. Therefore, when the material is exposed to infrared radiation and the temperature rises, the surface charge will decrease, which is equivalent to releasing a part of the charge, so it is called pyroelectric. The discharged charge is converted to a voltage output by an amplifier. This is how the pyroelectric sensor works.
When the radiation continues to act on the pyroelectric element and its surface charge is balanced, the charge is no longer released. Therefore, the pyroelectric sensor cannot detect constant infrared radiation.
Working principle: The human body has a constant body temperature, generally at 37 degrees, so it will emit infrared rays with a specific wavelength of about 10UM. Passive infrared probes work by detecting infrared rays of about 10UM emitted by the human body. The 10 UM infrared rays emitted by the human body are enhanced by the Philippine filter and collected on the infrared sensing source. The infrared sensing source usually adopts a pyroelectric element, which loses the charge balance when receiving the temperature change of the infrared radiation of the human body, and discharges the charge outward, and the subsequent circuit can generate an alarm signal after being detected and processed.
Pyroelectric effect: When some crystals are heated, an equal number of oppositely charged charges will be produced across the crystal. This phenomenon of polarization due to thermal changes is called pyroelectric effect.
Fresnel lens: According to the Fresnel principle, the Fresnel lens is divided into two types: refractive and reflective. Its role is to focus and refract (reflect) the pyroelectric infrared signal on the PIR. Second, the detection area is divided into a number of bright areas and dark areas, so that moving objects entering the detection area can produce a modified pyroelectric infrared signal on the PIR in the form of temperature changes, so that the PIR can generate a change electrical signal. The sensitivity of the pyroelectric human body infrared sensor (PIR) is greatly increased.
The Lunar Module in the National Air and Space Museum in Washington D.C.
It´s one of the 16 Lunare Modules which where built during the Apollo program.
Fish Module design by Francis Ow. Diagram provided in Nick Robinson's ebook "One Dozen Folds". Folded from six squares of 11.8cm kami.
This is my first module and was built in the spring of 1977. I based its theme on a Southern Railway Locomotive #722 Steam Train Excursion I rode between Richmond and Keysville VA some time earlier. It features a town with train station on the right and a lumber facility on the left served by a siding. This module made its first appearance at a NMRA-MER meet in Baltimore MD in the fall of 1977 and appeared again in a layout in Raleigh NC in November of 1977. It also made appearances in Princeton NJ in 1979, the NMRA 1982 National Convention in Washington DC and several appearances with the NMRA-MER conventions that the Tidewater Division hosted. It does not have a mountain division track, so in order to use it in layouts that use the mountain division, two more modules were built to swing the mountain division behind and back out again so that this module could be used in those layouts.

While this photograph was very different than the others I had presented in this course, I found that this was my favorite combination of pictures I had ever taken and edited together. In this photograph I intended to show the dream of a young woman being with her soulmate trapped and stopped by her current relationship and societal standards. I used some of my friends from school and my dorm bathroom to create the first image. I tired to make the lighting in the bathroom extremely yellow and dirty feeling. I wanted my two subjects to feel bigger than what the space was allowing them to be, almost as if the room was enclosing around the female subject. The photograph I laid over the base photo was one I took of the female subject, with another female subject, at a beach. They were playing in the water and running back on a cement path that was covered in water. I wanted to capture the dream that was the moment, the way they were having fun and the peace it omitted to not only them but to onlookers as well.
The way in which the photograph of the beach almost looks projected onto the walls of the shower shows how encompassed she is with this daydream, or the dream of her soulmate. The way in which it covers everything as a filter makes it change how the viewer sees the world they are in, showing them how the female subject sees the world.
When editing this photographs together I wanted to keep both the darkness of the base photo, and the dreaminess of the layered one. This was difficult to do but ultimately taught me a lot about balance, and how colors work together to create a photograph that is aesthetically pleasing. I really wanted to create the dream of my subject and show how it is unobtainable to her in a new and unique way. I think with both my editing and the strong compositions of both photographs, their coming together really worked well in the story I was trying to tell, both in terms of them being able to stand alone as parts of the story by themselves, and them working together in a way in which they equal there very own part of the story when together.
Playing with the camera and figuring out how to capture both a natural moment taking place and one that was staged was fun. It really helped me work on my artistic intuition as well as my directing capabilities. I think pairing the two really help the story come to life as well. Overall this is one of my favorite edited pieces.
I do believe this picture is a work of art, or that it is artistic because of the intention and story behind it, as well as the time and care I took to create it as if it was a painting.
