We Received The First Copies of Our d.i.y. Quantum Physics Book!

Today we received the first two copies of our new book! It is a do-it-yourself book on Experimental Quantum Physics, and was published by John Wiley & Sons. From the back cover: “Build an intuitive understanding of the principles behind quantum mechanics through practical construction and replication of original experiments. With easy-to-acquire, low-cost materials and

d.i.y. Moon Camera for EME and Radio-Astronomy Mounted on Space Communications Antenna Array

Our space-communicationsantenna  array includes a camera that looks in the direction that the array is pointing.  This camera helps us check that we are aiming directly at the moon during EME attempts.  In addition, when it lets us see airplanes that may be the source of interfering signals when we conduct radio-astronomy observations.

Crazy Pacemaker Hack: d.i.y. High-Speed Photography

This is a hack that combines three of my favorite passions: pacemakers, photography, and coffee! I took this photograph by feeding the output of an infrared barrier to the atrium input of an old DDD pacemaker, setting an appropriate AV delay, and using the ventricular output to trigger a camera flash (via a optoisolator).  In

Pictorial Instructions for Modifying ENI CD V700 into David Prutchi’s CDV700 Pro Geiger 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
