Beer IoT: Building Universal Windows Application to monitor cooling process

Our beer cooling solution is not controllable through IoT Hub and it reports data there. We can control our device through simple command line application but it is not enough for us. In this post we start building Universal Windows Application that helps us monitor temperatures. In this post we focus on mobile application. 13:15 05.02.2016 kanalilt DT blogi 2

Beer IoT: Visualizing sensors data using Power BI

We are eager to try out our beer cooling solution and we want to see it in action. We want to visualize our data and keep eye on temperature of cooling beer. Before doing anything more complex like building web or mobile app we make a quick shortcut and bring our data to web, desktop and mobile. This post is about Power BI in action. What is Power BI? Power BI is online data visualization platform by Microsoft. 21:23 04.02.2016 kanalilt DT blogi 2

Beer IoT: Using Stream Analytics to save data from IoT Hub to SQL database

When cooling beer we want to store history of temperatures for two reasons. First, it gives us valuable history data for next cooling sessions. As a second thing we can ask measurements when we temporarily lost connection with IoT Hub. In this posting we make some analyzis and then build up database for our beer cooling solution. 22:40 03.02.2016 kanalilt DT blogi 2

Beer IoT: Reporting measurements to Azure IoT Hub

As we have now fully functioning thermal solution running on Windows 10 IoT Core it’s time to focus to other components of our beer freezing solution. Our solution measures and calculates metrics of cooling beer but it doesn’t report this data anywhere. In this blog post we will set up Azure IoT Hub for our solution so it starts reporting measurements to Microsoft Azure. 15:48 03.02.2016 kanalilt DT blogi 2

Beer IoT: Estimating beer cooling time

In my last beer IoT post we measured out cooling rate of beer. In this post we try to estimate how long it takes for beer to start freezing. It’s actually simple calculation and we add it to our beer IoT background service before we focus on data reporting and persisting questions. NB! In this post we are using code from beer IoT posts Measuring temperature with Windows 10 IoT Core and Raspberry Pi and Measuring cooling rate. 08:56 03.02.2016 kanalilt DT blogi 2

Beautiful cross-browser equations with MathJax

Some posts about my IoT solution that helps me to cool eisbock beer to freezing needed mathematical equations. I know I can use poorly supported MathML or bitmap images but both of these solutions come with problems. I tried to find some better solution and found MathJax. 15:07 02.02.2016 kanalilt DT blogi 2

Beer IoT: Making cooling rate calculation testable

My previous beer IoT post introduced how to measure cooling rate of beer. As I introduced the first calculation there I implemented it in code the way it just works and gets calculations done. Now it’s time to focus on the implementation and make some small improvements that clean up code and improve technical design. Alhtough we can calculate cooling rate the calculation is not implemented very well. Here’s the current method. 08:56 02.02.2016 kanalilt DT blogi 2

Beer IoT: Measuring cooling rate

As thermal sensors are connected and we have code to read temperatures it’s time to get serious and start real work on supporting the cooling process of eisbock. We start with measuring temperatures, calculating cooling rate and estimating how long it takes for beer to freeze. This post focuses on cooling rate. In this blog post we are living in ideal world where there is always same temperature outside. 22:46 01.02.2016 kanalilt DT blogi 2

Beer IoT: Moving to ITemperatureClient interface

My previous blog post “Measuring temperature with Windows 10 IoT Core and Raspberry Pi” introduced you my simple solution for measuring temperatures. In this blog post we go step further and make some modifications to solution architecture so we don’t have to keep sensors connected all the time and as a result we can also emulate temperatures and situations that are not easy to produce in home or office. 12:11 21.01.2016 kanalilt DT blogi 2

Beer IoT: Measuring temperature with Windows 10 IoT Core and Raspberry Pi

I have RaspberryPi 2 with Windows 10 IoT Core and I plan to use it for some brewing activities. In this blog post I introduce you how to measure temperature with RaspberryPi using DS18B20 thermal sensors. This post is also example about how easy it is to get started with your IoT stuff using Microsoft tooling. In practice I use this solution to monitor the freezing of eisbock beer. Making 20l of beer freeze takes time. 01:54 21.01.2016 kanalilt DT blogi 2

Adding a service reference to ASP. NET vNext/ASP.

Recently I started a new project in ASP. NET vNext aka ASP. NET 5, or as it is known since yesterday, ASP. NET Core 1. 0. Since right now the framework is still in RC stage, there is next to no documentation to speak of… but that is a topic for another day. But I had to add several WCF service references to the project to communicate with the back-end server. 10:15 20.01.2016 kanalilt ...meie igapäevast IT'd anna meile igapäev... 3

Headspace – jõusaal vaimule sinu taskus

Viimastel aastatel on mitmed uuringud näidanud igapäevase meditatsiooni kasulikku mõju. Muu hulgas paraneb keskendumisvõime ja stressitaluvus. On võimalik uneprobleemide vastu abi leida.  Immuunsüsteem paraneb ja isegi keha püsib kauem noorena. 14:40 12.01.2016 kanalilt Digitark

iOS 9.3 toob mitmeid huvitavaid uuendusi

Peagi allalaaditav iOS 9. 3 toob i-seadmete kasutajateni mitmeid huvitavaid ning kasutuskogemust parandavaid funktsioone. Ühe põnevama uuendusena saavad iOS 9. 3 seadmed funktsiooni nimega Night Shift, mis seadme ekraanist eralduva sinise valguse hulka vastavalt kellaajale kohandab. 09:00 12.01.2016 kanalilt Digitark

CES-il nähtud tooted jõuavad peagi ka Eesti tarbijani

Eesti Telekomi esindajad viibisid sel nädalal Las Vegases toimuval tehnoloogiamessil CES 2016, kus paljud tehnoloogiafirmad olid väljas oma uudistoodetega.   Vähemalt osa messil nähtud tooteid jõuab tänavu ilmselt ka EMT ja Elioni tootevalikusse. Põnevad leiud Akupankade valik oli messil korralik ning neid oli näha seal seinast seina. 19:23 10.01.2016 kanalilt Digitark

Sander Klausen: Samsung Gear S2 Classic täidab nii ajanäitamise ja aksessuaari funktsiooni

“Sain ka testida nutikella Samsung Gear S2 Classic. Iseenesest põnev kogemus, sest mul pole nutikelladega üldse mingit kogemust ja enne selle kella saamist ei saanud ka aru, milleks see kasulik on,” kirjutab oma kogemustest ajakirjanik ja ettevõtja Sandel Klausen oma blogis. Loe lisaks:Stiilne nutikell Gear S2 erineb eelkäiast nii disaini kui kasutusmugavuse poolest. Foto: Samsung. 16:34 08.01.2016 kanalilt Digitark
