Uusiteknologia.fi is a Finnish language electronics and technology professionals magazine. In the newest issue have written articles on many high tech topics (text in Finnish with short introduction in English). The new number has been published as an electronic magazine that looks like a regular printed magazine. I have written to two articles to this →
The Micro Bit is an open source hardware ARM-based embedded system designed by the BBC for use in computer education for use in UK. It’s use has spread to many other countries as well. It is a quite nice Bluetooth IoT experimenting platform with low barrier of entry to programming. I have few years ago →
We were promised Intenet of Things interoperability on sales pitch, but we seem to end up is living with landfill full of proprietary shot-lived wallet gardens of crappy things. “But that Google can suddenly decide to sunset a cloud API that hundreds of IoT devices have been talking to for less than five years is →
While switching to LED lighting certainly helps reduce power consumption, we can do more. Each conventional mains powered LED bulb has its own AC/DC power supply, which is needed for bulbs to be compatible with AC wiring and lighting fixtures with sockets designed 100 years ago. Having individual power supplies adds cost and decreases efficiency →
Almost all connected device makers claim to care about security in their sales pitch, but the reality seems that the security of most device firmware is terrible. According to recent research the firmware security has not improved in any measurable way over the last 15 years, even as attacks on connected devices like home routers →
Last week when I visited Arrow IoT summit I saw Bluetooth location services in use. Two booth on the even showed Bluetooth positioning in two compartments. Quuppa Oy showed their own Bluetooth-based indoor positioning technology, which is used in many applications. With its unique Angle-of-Arrival (AoA) method and positioning algorithms, the system enables real-time tracking of →
I was on 23.5.2019 at Arrow IoT Summit conference at Helsinki Finland. According to event description: “Arrow IoT Summit brings together companies, top speakers and experts to discuss and develop the Internet of Things in Finland. In addition to inspiring examples and experiences from various fields, the event brings out the best IoT technologies and →
ARM’s Zach Shelby introduced the use of microcontrollers for machine learning and artificial intelligence at the ECF19 event in Helsinki on last Friday. The talk showed that that artificial intelligence and machine learning can be applied to small embedded devices in addition to the cloud-based model. In particular, artificial intelligence is well suited to the →
https://www.theregister.co.uk/2019/03/11/eu_directive_ban_rf_radio_firmware_tinkering/ EU plans to ban the sale of user-moddable radio frequency devices – like phones and routers. The controversy centres on Article 3(3)(i) of the EU Radio Equipment Directive, which was passed into law back in 2014. →
https://blog.arduino.cc/2019/02/06/announcing-the-arduino-iot-cloud-public-beta/ The Arduino IoT Cloud is an easy-to-use platform that makes it very simple for anyone to develop and manage their IoT applications, then deploy them to a large number of users. With the launch of the Arduino IoT Cloud, Arduino now provides its one million users a complete end-to-end approach to IoT that includes →
