Introduction This is a small bench power supply that is powered by two lithium-ion batteries. The project was inspired by Dave Jones from EEVblog but the design is completely mine. The voltage range is 0-20V regulated in 10mV steps and maximum current is 1A with current limit set in 1mA steps. Schematic Linear Voltage Regulator […]

Connect a basic sensor station to Arduino Cloud and visualize real time data. Story Following this tutorial you will build a little tower with several sensors and connect it to Arduino Cloud to visualize Real time data. Connect to Arduino Cloud Create an account and login to Arduino Cloud. If this is your first time on
I always considered circuit boards like this something you bought, not something you made. Not any more. I actually helped to make the board in the picture above. And it was awesome fun. The board is designed to monitor the conductivity (and, possibly, contamination) of water in lakes and streams, with the wonderful feature that
I credit the maker movement with bringing electronics back from the crusty old and lonely electronics hobby back into the main stream. The Arduino is the micro of choice for this army of makers and I conceded it made sense… you install the IDE, plugged in your board into the USB port and a couple
Introduction For charging relatively low capacity batteries, or maintenance charging backup and keep-alive batteries, linear topology battery chargers are valued for their compact footprints, simplicity and affordability. Even so, there is a dearth of linear chargers that accept a 10V or higher input voltage, leaving many industrial and automotive systems underserved. Some switch mode solutions
Monolithic linear battery charger operates from inputs up to 60V Continue Reading
This article explores an easy wireless communication setup between two Arduinos using low-cost ASK RF transmitter and receiver modules that are readily available in the market. They are found in different shapes, but functionally they are all same. Both Tx and Rx modules contain a single data line for input and output and support a

Featured on: BooSTick has captured imaginations around the world and has been featured on some really cool international online blogs and magazines! Slightly larger than a AA battery with holder, but supplies higher voltage for anything! This tiny board allows you to bring the power to your project, and not the other way around. Bring
Sodium. Potassium. Glucose. Lactate. Engineers at the University of California, Berkeley are focusing on measuring these components of sweat in an attempt to open an additional window into an individual’s health and well-being. A new device is able to calibrate the data based on skin temperature and transmit the information wirelessly in real time to
I wanted to probe a PCB at work to see how a ~500MHz differential clock was behaving. My trusty 100MHz oscilloscope was no use, it was too slow to see anything and unfortunately I couldn’t quite justify buying a $3k differential probe for my faster scope just for this. There are a bunch of DIY
An almost-GHz active differential oscilloscope probe Continue Reading
