“Introduction: If you’re a hobbyist that deals with audio, you’ll be familiar with dual rail power supplies. Most low power audio boards such as pre-amps require anywhere from +/- 5V to +/- 15V. Having a dual voltage power supply makes …
“Pulse sensors have become popular due to their use in health-monitors like the Fitbit. The sensors used are cheap, simple and pretty reliable at getting a reasonable indication of heart rate in daily use. They work by sensing the change …
“This instrumentation anthology of circuit notes contains more than 48 Circuits from the Lab designs specifically for analog, mixed-signal, and radio frequency (RF) design challenges within test and measurement applications. Instrumentation engineers can use these circuit notes as standalone solutions …
“The project stated a few years ago someone asked Frank if it was possible to emulate the C64’s Sound Interface Device (SID) chip on the Teensy 3.2. He found a good reverse engineered SID (reSID) and ported it …
“When we work on electronic circuits, there are some tools that get frequent use. Things like multi-meters, oscilloscopes, and waveform generators. Working with digital circuit has some use for those, but brings with it different requirements that require different tools …
“First in the world graffiti-drone with entirely autonomous. The project actualized for “Evolution 2.1” exhibition took place at Winzavod. The drone created the whole exposition. The performance was going live in huge exposition workshop. The project was done in …
“China’s spiraling space station, Tiangong-1, looks like it will plummet to Earth and burn up in the atmosphere sometime on April 1st — though where it will fall is still up for debate. So if you want to keep an …
“On this tutorial, we will capture remote data as UV (Ultra-Violet radiation), air temperature and humidity. Those data will be very important and will be used in a future complete Weather Station. The block Diagram shows what we will get …
“Starting next year, scientists will get their first look deep below the surface of Mars. That’s when NASA will send the first robotic lander dedicated to exploring the planet’s subsurface. InSight, which stands for Interior Exploration using Seismic …
