Portable Radiation Detector: 10 Steps (with Pictures)

http://www.instructables.com/id/Radiation-Detector/ Ever wondered how to make silicon radiation sensors? Here is a tutorial on them.  This is a tutorial to design, construct, and test your own portable Silicon photo-diode Radiation Detector suitable for the 5keV-10MeV detection range to accurately quantify low energy gamma-rays coming from radioactive sources!

The High School Student Who’s Building His Own Integrated Circuits – IEEE Spectrum

https://www.spectrum.ieee.org/semiconductors/devices/the-high-school-student-whos-building-his-own-integrated-circuits  Electronics enthusiasts like being able to make things themselves. But making DIY integrated circuits seemed impossibly out of reach. After all, building a modern fab is astronomically expensive. This article has an interesting story of a 17-year-old high school student who has started making chips in his garage fab. Zeloof was inspired by Jeri Ellsworth’s YouTube channel, where

Thoughts on the circuits you should publish | EDN

https://www.edn.com/design/analog/4459183/Thoughts-on-the-circuits-you-should-publish?utm_content=buffer26964&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer There are two fundamental categories that define what can and what should not be published: professional and consumer.  In general, virtually any circuit was safe to publish for a professional audience that usually understood any apparent hazards. And most circuits that had hazards had them pretty well spelled out.  In ignoring dangerous circuits, there

Audio jacks information

Audio jacks have been around for decades and have been used in a wide variety of applications. While simple in their basic functionality, they can be used in complex systems. Understanding Audio Jack Switches and Schematics document will help you understand some of their capabilities and will dig into the “guts” of these connectors.When looking

Testing op amp tools for their active filter design accuracy and dynamic range | EDN

This article tests three of the major on the same relatively simple 2nd order multiple feedback (MFB) example design.

Zero crossing detector circuits

Light Dimmers are devices used to lower the brightness of a light. Light dimmers are generally used to control light output from resistive incandescent, halogen, and sometimes also compact fluorescent lights (CFLs) and light-emitting diodes (LEDs). Dimming LEDs have their own set of challenges and dilemmas. Modern dimmers are built from semiconductors that are often

Simple circuits enable oscilloscope art

https://www.edn.com/design/analog/4421567/Simple-circuit-enables-oscilloscope-art?utm_content=buffer4a139&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer I built the circuit from this EDN article. I could not find exactly right component values from my lab, so I used 180 pF capacitor and 41 mH inductor instead.  I “powered” the circuit with 1 kHz 7Vpp square wave from signal generator. Then I got this nice graphics on digital oscilloscope screen in XY
