This is a video of an amazing light projection that was in public display in Helsinki just few days ago at LUX Helsinki annual light festival. Janne Ahola’s installation Time’s Role aims to break down the physical boundaries of perspective. It brings the courtyard façade of the Museum of Finnish Architecture to life by using →
http://www.instructables.com/id/Radiation-Detector/ Ever wondered how to make silicon radiation sensors? Here is a tutorial on them. This is a tutorial to design, construct, and test your own portable Silicon photo-diode Radiation Detector suitable for the 5keV-10MeV detection range to accurately quantify low energy gamma-rays coming from radioactive sources! →

This post is here to comments links and news on intetesting IoT products I see. I plan to post mainly information on new products, but sometimes I can post also information on older but what I see still relevat IoT products. I might also post here some embedded systems products that are not directly related →
I decided to replace my aging Zyxel and Netwjork 100 Mbit/s Ethernet switched with new gigabit models. I decided to get two ZyXEL GS-108S v2 Media Switch as replacement for those. The Zyxel GS-108S v2 10/100/1000 Mbps switch is designed to provide reliable high-performance media network connectivity – that’s what I need. The Zyxel GS-108S →

TechCrunch has made a lot of reporting over the years, so they have some idea what to expect. Connected homes will likely dominate the show yet again, led by the explosive popularity of →
Here is a list f IoT predictions for year 2018. With the number of connected devices set to top 11 billion – and that’s not including computers and phones – in 2018, Internet of Things will clearly continue to be a hot topic. Here is my prediction list: 1. Artifical Intelligence – it will be talked →
Here is story of VTI acceleration sensor interfacing. VTI is an originally Finnish company that has been mostly knows for it’s acceleration sensors. The company has been known with names VTI Hamlin and VTI Technologies, and is now part of Murata. I found some used sensors with three wires. I found no data, some but →
https://media.ccc.de/v/34c3-9058-everything_you_want_to_know_about_x86_microcode_but_might_have_been_afraid_to_ask#t=2250 This is a quite interesting presentation on Intel CPU secrets: Microcode is an abstraction layer on top of the physical components of a CPU and present in most general-purpose CPUs today. While it is well-known that CPUs feature a microcode update mechanism, very little is known about its inner workings given that microcode and →
https://www.twistlock.com/2017/12/27/escaping-docker-container-using-waitid-cve-2017-5123/ In 2017 alone, 434 linux kernel exploits where found, and as you have seen in this post, kernel exploits can be devastating for containerized environments. This is because containers share the same kernel as the host, thus trusting the built-in protection mechanisms alone isn’t sufficient. Make sure your kernel is always updated on all →
