So here it is! Courtesy of Dangerous Prototypes Dirty PCB service, I have been able to put together and complete the testing of the first prototype of my very own location based development board. So lets talk about what you’re looking at. The board is a 4 layer PCB of dimensions 50 x 68 mm. The populated […]

Microchip doubled the throughput and quadrupled the memory of its 32bit PIC family, and released a tool which brings third-party firmware into the firm’s integrated development environment (IDE), as well as adding new peripherals. Most of the up-grade has come from replacing the original MIPS M4K CPU, as used in the most recently announced PIC32MX

The BMP180 is a new generation digital barometric pressure and temperature sensor from Bosch Sensortec. In this tutorial, we will briefly review this device and describe how to interface it with an Arduino Uno board for measuring the surrounding temperature and pressure. We will also discuss about retrieving the sensor altitude from its pressure readings. Experiment setup

We copter hobbyists love RC FPV flying, and we have seen a lot of awesome FPV videos taken by professional and relatively large multi-copters. But It doesn’t have to be a big quadcopter or RC plane to do FPV. I recently looked into a cheap and light weight FPV solution, and I found a couple of

This interesting spray from the Kontakt Chemie portfolio will serve in an office but also at the production of electronics and in many other segments. Name “Label off” discloses a main purpose of usage of this spray. But that´s not all. Because Label Off is a mixture of solvents which particularly well dissolve sticky substances,
Label off will remove not only labels Continue Reading

After having an entire month of dormancy on this blog, I’m finally beginning to cross off the blog posts on my “Pending” list. Last year, I made a blog post talking about Kentli’s lithium-ion based AA battery that has an internal 1.5 volt regulator. The first order never arrived, and the second one had arrived

By Stephen Evanczuk Contributed By Hearst Electronic Products 2014-12-17 For rapidly growing markets such as wearables or the Internet of Things (IoT), energy harvesting can significantly enhance battery life—or even enable battery-free designs. At the same time, however, engineers designing wearables and IoT devices face significant constraints in total design size and footprint. To meet

Wouldn’t it be ideal if you could just press ‘print’ to produce a printed circuit board? In a paper titled ‘Instant Inkjet Circuits: Lab-Based Inkjet Printing To Support Rapid Prototyping Of Ubicomp Devices’ researchers Yoshihiro Kawahara of the University of Tokyo, Steve Hodges of Microsoft Research and Benjamin Cook, Cheng Zhang and Gregory Abowd of

Diodes Incorporated introduced a pair of compact 40 V, 1 A-rated gate drivers specifically designed to control the high-current power MOSFETs used in onboard and embedded power supplies and motor drive circuits. Enabling the MOSFETs to be more rapidly and fully switched on and off, the ZXGD3009E6 (SOT26 package) and ZXGD3009DY (SOT363 package) help minimize
