Developers, hobbyists and Raspberry Pi enthusiasts searching for a RFID or NFC reader powered by a Pico W sure to be interested in a new Kickstarter campaign launch for the aptly named ReadPi. Now in its last week of funding the ReadPi has already blasted past its required pledge goal with four days remaining and features a 125 KHz 13.56 MHz …
Most microcontroller implementation these days, use the traditional capacitor + crystal approach to generate their clock, this approach sometimes, however, lead to problems, especially when used in prototyping situations with a breadboard, jumper wires, etc., all of which have an (unknown) inherent capacitance that could lead to the clean 8 or 16MHz signal we desire, …

Introduction Eddy currents are magnetic fields created whenever a current passes through a conductor. They’re usually found only in particular scenarios. the typically application is the conductivity testing. Eddy currents can be used for testing virtually any metal. They have several advantages over other testing methods. Eddy currents are fast, safe, and completely non-contact. Once …
A couple of years ago Skytraq launched the NavSpark mini, a tiny (17x17mm) GPS module, that sold for $6. However, the company has now launched an even smaller module called Skytraq PX1122R, which measures at just 16x12mm, and offers support for GPS, Galileo, GLONASS, and Beidou signals, as well as Real-time Kinematic (RTK) relative positioning technique that enables 1-3cm positioning accuracy. The Skytraq PX1122R RTK GNSS …
