Dr Patrick Cabe who is a member of the emeritus faculty at the University of North Carolina at Pembroke Department of Psychology, is the first to describe how to make a fully functional multi-aperture pinhole camera using a biscuit [‘cracker’ US]. Dr Cabe engaged in a practical demonstration of his camera to (indirectly) view the 2017 […]

The ‘Singing Cymbal’ controversy
The photo above is a still from a CERN teaching resources video (2014). “Use a cymbal or metallic plate that can vibrate freely. Use a flash, for example from a camera, hold it close to the plate and flash. You will hear a low tone. Physics: The moment of the photons are transferred in an […]
New uses for old CDs (part 3)
Got old CDs? Looking for uses for them? Have you thought about their application in crime scene photography? “Tripod legs of cameras often sink into sand, mud, or snow. To avoid this, old CDs can be used by placing approximately three of them under the feet of the tripod. CD’s can also be used as […]
The jet powered maple seed (new patent)
In 1992, Litos et al. patented their bio-mimic throw-in-the-air toy called the ‘Autorotative Flyer’. It might not occur to everyone that the passive toy could be updated, and militarized, with the addition of a supersonic jet pack. But occur it did to high-tech weapons manufacturer Lockheed Martin Inc. which has just received a US patent […]
Sensing and Sensibility: “Development of Anal Position Detecting System for New-Toilet System”
Technology for the elderly grows more ambitious and, arguably, more adventurous. This paper sets a new standard: “Development of Anal Position Detecting System for New-Toilet System,” Koshi Tokoro, Keisuke Fujihira, and Hiroshi Kobayashi [Department of Mechanical Engineering, Tokyo University of Science, Tokyo, Japan], paper presented at the 2013 Seventh International Conference on Sensing Technology, December […]
The distance between musical notes
Today’s quick calculation exercise is to calculate the relative distances between different musical notes and a trombone player’s face. Watch this video of a trombone player playing a tune on a trombone. A GoPro camera has been affixed to part of the trombone, and aimed at the musician’s face: (Thanks to investigator Dorothy Bond for […]
Paparazzi Zapper (New Patent)
“Photography has been around for many years. A problem associated with photography is oftentimes many people do not want to have their picture taken. For example, many celebrities do not want their picture taken or pictures of their companion’s [sic?] or relative’s [sic?] taken because they feel it is an invasion of their privacy.” What […]
What it takes to read a science journal
It takes more something special to read the online version of the science journal Frontiers in Bioscience. Or so they themselves say. Investigator Michael Strack visited the journal’s web site, then wrote us this note (why he wrote it to us, rather than to Frontiers in Bioscience, we do not know): “I noticed in the ‘about us’ […]
Boobies at Sea, with Cameras and Comrades
Today’s Boobies-at-Sea Study-of-the-Day is: “Social Interactions of Juvenile Brown Boobies at Sea as Observed with Animal-Borne Video Cameras,” Ken Yoda, Miku Murakoshi, Kota Tsutsui, Hiroyoshi Kohno, PLoS ONE 6(5): e19602. doi:10.1371/journal.pone.0019602. (Thanks to investigator Robin Abrahams for alerting us to it.) The authors, include video, some of which you can watch (or, depending on how […]
Pet-face-detecting camera
The Pentax Optio I-10 camera includes face detection technology for detecting pet faces, according to Pentax, which has not trumpeted the news but instead mentioned, almost mumbled, it in the device’s lengthy technical specifications: Face detection available: Yes (up to 32 faces in 0.03 sec), Smile Capture, Blink Detection, Pet Recognition (3 faces) (Thanks to […]
