My new book “Exploring Ultraviolet Photography: Bee Vision, Forensic Imaging, and Other Near Ultraviolet Adventures with Your DSLR” is now available on Amazon for pre-order. In this book, I will show you how to select equipment that allows you to capture otherworldly UV images. You’ll learn how to use filters that block visible light and
The DOLPi Raspberry Pi-based polarimetric cameras received 5th place in the 2015 Hackaday Prize. Winners for this year’s prizes were announced on stage at the Hackaday Superconference on November 14, 2015. The DOLPi project involved the development and construction of two low-cost polarimetric camera types based on the Raspberry Pi 2. DOLPi-MECH (and its productized
Possibly the Only Accessible Border Demarcation Pillar Placed under the Franco-British Boundary Agreement of 1920
My brother in-law, an Ob/Gyn physician and retired high-ranking Israeli Army officer is also a history scholar. He recently took us offroading in the Gallil to a rather unknown site that he found through his research on the Franco-British Boundary Agreement of 1920. This agreement established the boundary between the Mandate of Palestine attributed to
Abigail and I are back from the Galapagos Islands. This was my fifth time there, and certainly the best yet! Like the two last times, I used Ecoventura to organize the trip, and continue to be impressed by their outstanding dedication to service. Ecoventura operates three 16-passenger cruise yachts and one diving catamaran. The three
This summer we fulfilled a life-long dream (at least for some of us) and visited the Arecibo Observatory in Puerto Rico. This is the largest single-dish radiotelescope in the world. The reflector is 305 m (1,000 ft) in diameter – a tad bit larger than our home-brewed radiotelescope. The Arecibo system is a semi-transit telescope
Our DIY work on Quantum Physics was featured this month in MAKE Magazine and the Philadelphia Exponent!
We had a fantastic time this weekend at the US Science and Engineering Festival in Washington DC. Among the highlights of our visit, we sat insanely close to the stage for the Q&A with Mythbusters Jamie Hyneman and Adam Savage. We also had the pleasure to meet fellow diy Science authors Theo Gray (Mad Science, The Elements,
I urgently needed a high-intensity UV/IR/visible light source for a work-related industrial inspection project, so this weekend I recruited Abigail to help me build a 10W LED flashlight that features swappable UV/IR/visible heads. We decided to document the build since this flashlight would fit nicely in a photographer’s kit for light painting, IR illumination, UV
Posted to diyPhysics.com: Testing Electronic Goldmine’s “Giant Super Sensitive Geiger Muller Tube MC6”
I purchased two “Giant Super Sensitive MC6” GM tubes from Electronic Goldmine (Item Number : G18717, Unit Price: $89.95). These are Russian-made new-old-stock model MC6. They are 10.25″ long x 0.9″ diameter. I compared the sensitivity of these tubes to the other GM tubes that I use with my CDV700 Pro Geiger Counter. I posted
I had some business meetings in England this week, and on my way back to Birmingham Airport I stopped in Stratford-Upon-Avon to see the houses where Shakespeare was born and died. Warwick Castle was also along the way, so I stopped briefly to take a few pictures before sunset.
