I ordered some time ago Arduino Sensor Shield v4.0 because it is an easy way to connect input and output devices to Arduino. Arduino Sensor Shield provides three pin (ground, voltage, signal) interface for connecting all kinds of sensors (potentiometer, button, LDR etc.) and output devices (relay cards, servos etc..) to Arduino. The Arduino Sensor →
Finnish Communications Regulatory Authority Viestintävirasto had a Tietoturva nyt! 2013 security seminar two weeks ago. Viestintävirasto has now published the seminar presentations. Most of the presentations are in Finnish, but there are also four presentations in English. If networking and cyber security interests you those are worth to check. →
Arduino platform seems to interest many Internet of Things developers. There are now many Arduino compatible platforms with wireless connectivity as you can see in my New interesting Arduino platforms article and it’s comment. Also Google has done some Arduino based IoT. Arduino launches Yún for WiFi connectivity under Linux article tells that Arduino has →
Flexible printed circuits are useful when the size and shape of your invention is integral to its overall design. Very many consumer electronics gadgets have them inside: in mobile phones, cameras, etc. Tips for Building a Flex Circuit article tells that because of the unique characteristics that set them apart, an electronics engineer must consider →
I have written earlier on new Finnish mobile phone company Jolla at my Two new mobile phone companies from Finland and Mobile trends and predictions for 2013 articles. Jolla announces its first Sailfish OS smartphone which will be available in Europe by the end of 2013. The first Jolla phone: 4.5-inch display, Android app compliant, →
I some time ago wrote about phatIO file system based USB I/O and this is a continuation to this article. On weekend I successfully tested phatIO Dropbox Integration. The idea is the files on phatIO can be exported to dropbox allowing a cheap way of exporting the phatIO functionality to other computers or other devices →
Are you interested in seeing how light propagates? Filming light reflecting off objects article tells about a method for capturing “light in flight”. Making videos of light passing through and around objects has been done before, but this system is much cheaper (few hundred dollars) than those earlier systems ($300,000). Light-in-Flight Imaging page on that →
Many people working in large companies speak business-buzzwords as a second language. Business language is full of pretty meaningless words. I Don’t Understand What Anyone Is Saying Anymore article tells that the language of internet business models has made the problem even worse.

Some days ago I had to help a friend to interface several microphones to a Canon camcorder microphone input. I had interfaced earlier years ago microphones to several prosumer and professional video cameras, but I though it would be a good idea to do a Google search to check what is said on interfacing to →
At I/O, Google Will Be Tracking Things Like Noise Level And Air Quality With Hundreds Of Arduino-Based Sensors article tells that in the blog post, Michael Manoochehri, Developer Programs Engineer, outlines his team’s plan to place hundreds of Arduino-based environmental sensors around the conference space to track things like temperature, noise levels, humidity and air →
