David Prutchi's CDV700 Pro Geiger Muller Counter

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!

David and Shanni PrutchiWe 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!

Why should you adopt this book as your Quantum Physics lab course textbook?

Our book explains Quantum Physics through hands-on experiments that the reader can perform at school. Throughout the book we guide the reader 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 by the reader out of relatively inexpensive materials that are readily available at the hardware store or from on-line vendors of electronic surplus.
