Completed by Kristen Stevens, Karem Gonzalez, and Leslye SaavedraAn electrostatic polarity detector can be used to detect if an object is negatively or positively charged. We followed the steps from the following youtube video: Materials: FDS8958A …By: kri2190522 Continue Reading » Instructables: exploring – featured


Creeper Detector

For a couple years, I helped the Children’s Museum of Bozeman develop curriculum for their STEAMlab. I was always looking for fun ways to engage kids with electronics and coding. Minecraft is an easy way to get kids in the door and there are tons of resources for using it in fun and educational ways…By:(…)


ATTiny EMF Detector

As is tradition, finished product image first.Inspired from masteruan’s similar build, which I will link below, I set off to build my own micro sized Electro-Magnetic Field Detector. The goals were to make this as small as possible while retaining enough stability that it would not break in someone’…By: bcb10 Continue Reading » Instructables: exploring(…)


Radiation Detector

Building a "semi-directional" radiation and cosmic-ray detector is not an easy feat. I aimed to design, construct, and test a portable and versatile Silicon photo-diode Radiation Detector suitable for the 5keV-10MeV detection range to accurately quantify low energy gamma-rays emanating from radioact…By: wavelet_spaghetti Continue Reading » Instructables: exploring – featured
