There seems to be a push for all kinds of ARM based development boards. pcDuino looks to be another interesting ARM platform that runs Linux. The name comes from Mini PC + Arduino. pcDuino is a mini PC platform that runs PC like OS such as Ubuntu and Android ICS. It outputs screen to HDMI. →
Grounding, or connecting some part of an electrical circuit to ground ensures safety for personnel and it usually improves circuit operation. Unfortunately, a safe environment and a robust ground system often do not happen simultaneously. It takes planning based on systematically understanding how electricity behaves in various types of circuits. Preventing electrical shocks and electrical →
I needed one more Arduino board, so I planned to check out this cheap (US$14.30) Duemilanove 2009 Atmega 328P SCM Board with USB Cable board. This is a clone of the Arduino Duemilanove with several enhancements not available in the original Arduino. The most important that is on board 2.54 grid male pin headers an →
Congratulations, you did it! The small things are exhausting, so kudos to you for getting through the day. 14 Ways To Reward Your Motivation article show you some ways to give yourself a well-deserved pat on the back. Relax. You deserve it. This article is full of funny GIF animations. →
Availability of reasonably priced fast broadband connections has made making off-site backups of computers over Internet feasible. This kind of off site backup business started with expensive small off-site storage services (few gigabytes of storage many dollars/euros per month). That business is then competed with small free off-site storage services (for example Dropbox, Google Drive, →
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, →
