Security for the ‘Internet of Things’ (Video) posting an Slashdot provides one view to security of Internet of Things. What happens when your oven is on the Internet? A malicious hacker might be able to get it so hot that it could start a fire. Or a prankster might set your alarm in the middle of night. →
I needed to interface PC to some RS-485 test circuits, so I decided to try this cheap USB to RS485 Adapter – Black + Green adapter for that. I selected this specifically because of the cheap price (it is considerably cheaper than anything else I have seen for the same purpose). There should not be →
I have written about Arduino boards a lot, but there are also other small interesting quite similar development board recommended for me to check out. The Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port and →
I needed to do some AC current measuring with Arduino, more accurately than with special AC current sensor I tested earlier. To do that measuring I bought Meeeno ACS712 Current Measuring Sensor Brick Module Board for Arduino. This is a picture of that module from dx.com: This module is pretty easy and safe way →
What do you do when your micro-controller project runs out of horsepower? Well you increase the power in a way or another, like increasing clock speed (maybe up to over-clocking) or change to a faster processor family. What to do when your Arduino Uno isn’t fast enough? The UNO Overdrive article shows The Uno/Dumilanove Overdrive, →
Did you know that your optical mouse contains a very tiny, very low resolution camera? Your Mouse Is A Terrible Webcam article tells how to turn that tiny optical sensor into a webcam. Logitech RX 250 has an ADNS-5020 optical sensor (15×15 pixel grayscale image sensor) with SPI interface. The project uses Arduino, Ethernet shield, →
The Internet of Everything is coming. The Internet is expanding into enterprise assets and consumer items such as cars and televisions. Very many electronics devices needs to be designed for this in mind. The Internet of Things (IoT) will evolve into the Web of Things, increasing the coordination between things in the real world and →
Here’s a cool hack to get you in the December holiday mood! Time to set up some Christmas lights, maybe even computer controlled LED lights. First idea to try: Arduino controlled Christmas lights! How about this Gemmy Lightshow LED Christmas Lights Or a Pedal Powered Menorah Other videos: 2012 Christmas Lights Show (GE Color Effects →
Despite the cries for updated hardware, the Raspberry Pi foundation has been playing it cool. The Raspberry Pi Becomes a Form Factor article tells that they’re committed to getting the most out of their engineering investment, and the current board design for the Raspi doesn’t support more than 512Mb of memory, anyway. It seems that →
European Robotics Week 2013 is celebrated from 25 November to 1 December 2013. The Week aims at inspiring technology education in students of all ages to pursue careers in STEM-related fields, i.e. science, technology, engineering and math. At the same time Finnish robot week “Robottiviikko” is celebrated in Finland. I happened to walk by Robots →
