Welcome to Prutchi.com!

Welcome to our site, a blog dedicated to the cutting-edge do-it-yourself projects that we develop at home.

Shanni and David are the authors of the book “Exploring Quantum Physics through Hands-On Projects,” which will help you understand Quantum Physics through hands-on experiments that you can conduct at school or at home! For our modern/quantum physics site, please go to diyphysics.com.

David is also the author of the book “Design and Development of Medical Electronic Devices,” which will let you master the building blocks of medical devices. David has over twenty years of experience in the design of Medical Electronic Instrumentation, most of it developing active implantable medical devices. For David’s implantable devices site, please go to implantable-device.com.

We discuss all of our other projects on this site. There is plenty of information, so take your time exploring.  Please navigate through the permanent pages, as well as through the many blog post categories listed in the sidebar to the right.

We hope that you enjoy reading our blog.

New Book on Ultraviolet Photography

Exploring Ultraviolet Photography book by David Prutchi PhD.

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 prevent infrared light leaks and will discover how supplementing or overpowering sunlight with artificial UV light sources can help you create stronger images. You’ll also learn postprocessing techniques designed to enhance your UV photographs.

There is much to discover about the world as seen by bees, birds, and butterflies (and other creatures). I will take you into the wild to capture UV images that show how flowers advertise their nectar with beautiful markings to attract pollinating insects and birds. You’ll also discover how butterflies that look dull in visible light burst with intricate, iridescent patterns in UV.

Finally, you’ll learn about the scientific, medical, and forensic uses of ultraviolet photography.

From start to finish, this book will educate, inspire photographic creativity, and foster a better understanding of the UV world.

DOLPi DIY Polarimetric Camera Awarded 5th Place in 2015 Hackaday Prize

David Prutcho PhD 5th place Hackaday prize winner

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 IR-VIS-UV version DOLPi-UI) is a filter-wheel-type camera capable of performing full Stokes analysis, while the electro-optic based DOLPi-EO camera performs full linear polarimetric analysis at higher frame rate. Complete Python code for polarimetric imaging is presented. Various applications for the cameras are described, especially their use for locating mines and unexploded ordinance in humanitarian demining operations.

CLICK HERE for a complete project description including detailed construction instructions and Python code in pdf format.

Possibly the Only Accessible Border Demarcation Pillar Placed under the Franco-British Boundary Agreement of 1920

 

Border marker pillar Syria Lebanon Palestine Israel 1920 David Prutchi PhD

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 Great Britain, and the Mandate of Syria and the Lebanon, attributed to France.

We trekked to what may be the only accessible border demarcation pillar placed under the Franco-British Boundary Agreement of 1920. In 1922, 38 of these boundary markers were placed along the 49-mile (78 km) boundary. According to Newcombe-Paulet field survey of 1923, 71 boundary pillars were erected on the Syria/Lebanon border with Palestine. Most of these boundary pillars are either inside mine fields or have been removed by looters or people ignorant of their historical significance.

I haven’t been able to find even one picture of such a boundary pillar on the Internet, so my series of shots may be unique…  This picture, by the way is of the boundary marker at “Cairn 45”.  More pictures are available on my Flickr set.

Back from the Galapagos Islands – My best trip yet!

Blue footed booby, Galapagos Islands, (c) David Prutchi, Ph.D. 2012

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 cruise yachts are identical to each other, and I’ve travelled in all 3 with equal comfort (“Flamingo” with Shanni, “Eric” with Hannah, and “Letty” with Abi).
Ecoventura's Letty, Galapagos Islands, (c)2012 David Prutchi, Ph.D.
My preference is to use these yachts instead of the larger ships (that can hold up to 100 passengers) because of the personal service, and especially because Ecoventura keeps their landing groups small – a maximum of 10 passengers per Naturalist Guide.  Since yachts/boats get equal visiting slots from the National Park, being the only group on an island, and having a naturalist just for your group makes an enormous difference.  I have travelled in the larger ships, and because of this difference wouldn’t go back.
As a disclaimer – I’m not related to Ecoventura in any way besides being a very satisfied repeat customer.

Pilgrimage to the Holy Dish

Prutchi family visit to Arecibo Observatory Radio-Telescope in Puerto Rico. Dsvid Dorith Shanni Hannah Abigail Prutchi diy radio-astronomy

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 that has a fixed primary reflector with secondary (Gregorian reflector) and a delay-line feed.

Great Time at US Science & Engineering Festival in Washington DC

Shanni Prutchi with fellow diy SCience author Theodore (Theo) Gray

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, Popular Science’s Gray Matter, etc.) and William Gurstelle (Backyard Ballistics, Whoosh Boom Splat, The Practical Pyromaniac, etc.).
