Proximity sensors working on an induction principle are able to detect ferrous and non-ferrous metals very reliably. For those of you, who already work in this field, there´s everything clear for you probably and you know well, that induction sensors are literally one of the keystones for an industrial automation. For all of you, who´re […]
Induction sensors don’t need a touch, they’re satisfied by proximity Continue Reading

In this tutorial Dave demonstrates the seldom used and often little understood mathematical integration function available on your modern digital oscilloscope. And demonstrates a practical example use for it in accurately measuring the total power consumption of a microcontroller that sleeps and then wakes up and does some processing before shutting down again. By getting

I have been hearing about so many different and novel techniques for battery charging and cell balancing lately. Designers are working feverishly to optimize cell balancing and battery safety along with improved efficiency. I have been closely watching Sendyne for a while now, ever since the SFP100 was chosen to be one of 2013’s EDN
Unique battery pack architecture patented by Sendyne Continue Reading
Dave shows you how to reverse engineer a PCB to get the schematic. In this case the new Rigol DS1054Z oscilloscope. How does the discrete transistor analog front end and the software bandwidth limiting work? How do you decode SMD transistor codes? How does it compare to the old Rigol DS1052E? Dave also discusses the
Nobody likes having blood samples drawn. What’s more, such samples typically have to be analyzed in a lab before they’re able to tell us anything. But now scientists at the University of Cincinnati and the US Air Force Research Laboratory are developing a system in which a Band-Aid-like skin patch is able to gather and
Sweat-analyzing skin patch could replace blood sampling Continue Reading

Introducing PCBWeb Designer, our new desktop schematic capture and layout tool that’s free and easy to use. Create multi-sheet schematics, use the parts toolbar that includes the Digi-Key parts catalog, in a browsable and searchable database. The PCB view is always in sync with your schematic, and includes all the tools you need to create a design with up to 12
The Raspberry Pi is much more powerful than an Arduino but it has a few limitations of its own. Its I/O is much more limited, it can’t use common Arduino shields, and it needs a regulated 5V power supply via its USB connection. All those limitations are solved with the PiLeven. The Freetronics PiLeven is
