https://opensource.com/article/17/7/nodered-raspberrypi-hardware?sc_cid=7016000000127ECAAY Node-RED is an easy-to-use programming tool that can be used for handling IoT signals. This article shows that Node-RED can also be used to quickly integrate and test hardware devices. As you can see from this tutorial, connecting and testing a cellular mode with Raspberry Pi using Node-RED required no coding at all. For more information about →

https://opensource.com/life/16/9/iot-home-automation-projects?sc_cid=7016000000127ECAAY We live in an exciting time. Everyday more things become Internet-connected things. They have sensors and can communicate with other things, and help us perform tasks. Home automation is made possible by amaetuer developers and tinkers because the price of microcontrollers with the ability to talk over a network continue to drop.  Along the way, the writer has learned →

http://makezine.com/2017/06/27/state-boards-platforms-products-purposes-current-crop-microcontrollers-vies-attention/ Over the last few years, we’ve seen a huge growth in the number and variety of both microcontroller boards and single-board computers.  The modern era, defined by microcontrollers becoming conveniently packaged on boards, began with the Arduino. The “classic” Arduino layout, including the irritating, irregular offset between pins 7 and 8, has become a standard. Similarly, →

http://hackaday.com/2017/06/20/practical-iot-cryptography-on-the-espressif-esp8266/ This article will focus on applying AES encryption and hash authorization functions to the MQTT protocol using the popular ESP8266 chip running NodeMCU firmware.   →

http://www.techrepublic.com/article/raspberry-pi-simulator-lets-you-start-tinkering-without-even-owning-a-pi/ Microsoft is building an online Raspberry Pi simulator that allows Makers to write code to control hardware… even without owning a board. At present, the simulator is in ‘preview’ and is quite rudimentary. →

http://www.cnbc.com/2017/06/12/apple-co-founder-wozniak-motivation-is-more-important-than-knowledge.html The most important ingredient to becoming successful is having motivation, says Apple co-founder Steve Wozniak. “If somebody is motivated and wants to do something, wanting — it’s emotional. That’s the person that is probably going to go out and find a way to actually get it done.” The Internet has made it possible for anyone with the →

I visited Embedded Conference Finland 2017 around one month ago ( May 3, 2017). I wrote about it in Finnish to Uusiteknologia.fi web site. Ufortuantely I did not have time at the moment to write material on it to this blog. Here is some material on that here.  Here are some slides and advice picked →

https://pentestmag.com/write-secure-code-cc-programming-languages/ Secure coding in C/C++ programming languages is a big deal. The two languages, which are commonly used in a multitude of applications and operating systems, are popular, flexible, and versatile – and often vulnerable to exploitation. Sometimes the solution is to code using a safer language like Java. However, this is not always the →
