Got myself a new toy a while ago – A FLIR TG165 infrared camera. These devices used to cost thousands of Euros/Dollars, but during the past year the have come down in price a lot. I got mine from SOS electronic, think they had a campaign on it back when
Once you got yourself a good multimeter, a good LCR meter is probably the next step. Remember to discharge any caps before measuring them though - otherwise the result might be what caused this post...
Probably pretty obvious when thinking about it in retrospect, but this one hit us the other week. After setting up some Qlik Sense servers without any real issues (rather the opposite – it is incredibly quick and easy to deploy an Enterprise scale Sense system!), one day one of the rim
Lots of OS upgrades lately, Windows went to Windows 10 and Apple to El Capitan. I am usually pretty ok upgrading to Apple’s latest OSs a week or two after their release – they are usually of good quality. As VirtualBox (“VBox”) also came out with their version 5 release,
I finally got around to start using GitHub Gists a bit more systematically for storing useful bits of code. Going forward I will post useful, reusable pieces of Qlik Sense and QlikView code there. My own experience tells me there is tons of time to be saved by reusing existing
Continuing from the previous post about publishing data from Telldus Live to MQTT, here is small piece of related Node-RED code. It outputs a list of all (wirelessly controlled) 220V/mains switches I have linked to Telldus Live, using a Tellstick Net. The background of the code was simply
Telldus has a set of nice little gadgets (“Tellstick”, for short) that both allow you to control remote switches over radio (433.92 MHz), and to read sensors transmitting on that same frequency. Telldus also has a backend service, Telldus Live, which offer Tellstick users scheduling features (turning lamps on/
Synology NAS:es are pretty capable devices. Let's look at how they can host a Mosquito MQTT broker.
The previous post listed some of my favourite OS apps, but there are a few more that also make everyday life easier. When thinking about it, the apps below are just as useful and important as the ones in the previous post. The apps are: * Wunderlist: Todo tracking * Carbon Copy
Being fairly multilingual – I use Macs, Windows and Linux boxes daily – OS X has during the last 4-5 years been the main platform for daily work. And as much as I like the way OS X has developed over the years (including the fact that it’s free once
Turns out that OS X Yosemite on Mac Mini does not support standard Wake-On-Lan (“WOL”), at least not when using the built-in Ethernet port. Which is strange – but when trying to make the media server attached to the household’s TV a bit more energy efficient, I
I must say I am pretty happy with the backup solution here. It took a few years to find a setup I am happy with, but this one works: * Storing important files and data on the Synology DS1515+, with ca 8 TB disk (effective raided size) and 2 SSD drives
