“Simple to build, but serious instrument for monitoring and predicting weather disasters. Lightning detectors are devices designed to detect the presence of lightning strikes. These detectors utilize various technologies to sense the electromagnetic signals like detecting of Radio Frequency (RF …
“If properly adjusted according to the instructions, it is able to detect a small coin at a distance of 15 cm In this project I will present you a Very Simple “Beat Frequency Oscillator” type of Metal Detector. BFO metal …
“Do you have rooms in your house that are colder than other rooms in the winter? If you have air conditioning, are those same rooms warmer than other rooms in the summer? It’s common for that to happen to …
“This is the Technological Tesseract—an electronic puzzle box. The goal of this puzzle is to connect three wires to the jacks in the correct configuration to make the LED matrix light up in a fun way. There are four …
“An adaptive decoder for LTC data This is my third (and probably last) post on the topic of Arduino interrupts and timers. In the first two, we discovered how to generate regular interrupts with precise timing, then how to use …
“When I was a kid, there were several political murders in the ex-YU that involved people who had Surveillance Systems that mysteriously stopped recording during the event and resumed without an issue immediately afterward. Weird right? With no evidence …
“Cranial electro stimulation uses harmonic frequencies to help balance the brain’s chemistry. Cranial electro stimulation uses harmonic frequencies to help balance the brain’s chemistry. By connecting with the body’s control center, the brain harmonic frequencies provide wide-ranging …
“This is my next build using LED matrix’s. You may have seen my last one - 81 LED Chaser, well this project uses 100 LED’s and is an oscilloscope! Admittedly, the resolution isn’t great for checking measurements (it …
“Using the ADP3450, this project measures amount of delay between asserting FPGA IO on base of NPN 2N3094 and LED illuminating on collector. Signal timing is a huge component in FPGA design, and while many tutorials demonstrate how to handle …
“This is actually a really simple circuit, using just one hex-inverter chip and a handful of small, common components. Discover step-by-step how this circuit works by building it on breadboard first with a detailed guide. Finally, build the finished instrument …
