Handheld printers are changing what we think we know about getting digital prints on an object/surface. They are allowing users to print whatever they want, from logos to pictures, on whatever surface they want, from clothes to books and merch, in a manner that we would have considered impossible a few years back. While they […]

Being able to turn a USB-C supply to a variable power supply is certainly a big deal for a simple ingenious board like the ZY12PDN board shared by Keneth Finnegan on his twitter handle recently. The ZY12PDN is a simple STM-powered adapter board that turns a USB-C supply to a universal power supply for almost any electronic device. We know […]

The circuit in Figure 1a comprises a voltage follower, IC1 , and the reference-voltage source of IC2. IC1 is an Analog Devices AD8661 op amp, which has a guaranteed input-bias current of no more than 1 pA and a typical input-bias current of 0.3 pA (Reference 1), and IC2 is an Analog Devices ADR391 precision voltage reference (Reference 2). The manufacturer trims […]

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 […]

SparkFun has announced another experimental SparkX board design, which enables higher motor control on a Qwiic-compatible I2C bus, with support for a built-in emergency stop button, and the capability to drive motors requiring up to 2A. The Qwiic Step is the latest of SparkFun’s entry in the SparkX board family, which are ranges of experimental designs marketed as fully-operational devices, but without guaranteeing them being […]

USB Type-C introduced significant changes to the USB standard. The reversible connector eliminated the issue of trying to plug the connector in the right way every time. Another issue it addressed was allowing the flexibility to have USB power with an adjustable USB voltage from anywhere between 5V and 20V and up to 100W of power. […]

I enjoy creating sumo robots and am constantly searching for innovative sensors and materials to improve the speed and intelligence of my robots. I discovered the RPLIDAR A1, available for $99 on DFROBOT.com. I mentioned my interest in testing the sensor, and they offered me the opportunity to test it out. Once I obtained the […]
