This is an inside view of our X-Band Gunnplexer transceiver (book‘s Figure 12) that should help you build your own units if you follow the schematics shown in the book’s Figure 11 . It is used throughout Chapter 1 for experiments in microwave optics, in Chapter 6 to measure single-slit diffraction, and in Chapter 7 to experiment with Quantum Tunneling. Continue reading
This is the surplus Gen III image intensifier tube (an MX-10160 Gen III intensifier tube used in the helmet-mounted AN/AVS-6 “ANVIS” aviation night vision imaging system, which we purchased on eBay®) that we used to build our setup to image interference patterns from our single-photon two-slit setup (book‘s Figure 93). The tube is supplied by 3VDC from two AA cells. We used the same camera to record interference patterns from a single-photon Mach-Zehnder interferometry setup (book‘s Figure 132). Continue reading
We modified a surplus Civil Defense V-700 radiation survey meter made by Electro Neutronics Inc. (Model 6-b) into a very capable radiation counter capable of working with both Geiger-Müller and PMT scintillation probes. We modified the front panel to accommodate the new switches, connectors, and panel light. In addition, we placed a Veeder-Root count totalizer module on the side of the box. The new electronic components, including a Zener diode stack and a PMT preamplifier are wired directly to the original printed circuit board. Continue reading
Welcome to diyPhysics.com, a blog dedicated to the advanced do-it-yourselfer interested in modern and quantum physics!
We 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!
Our book will guide you in the construction and use of setups to reproduce the key experiments that have brought us to our current understanding of the quantum world. Importantly, all of the experimental equipment can be built out of relatively inexpensive materials that are readily available at the hardware store or from on-line vendors of electronic surplus.
The projects range from simple measurements of Planck’s constant all the way to testing violations of Bell’s inequalities using entangled photons. The project descriptions are targeted to an audience with basic experience in electronic prototype construction. The circuits actually work, and the schematics are completely readable.
We hope that you enjoy reading our blog!
