Voice over Sigfox?

I am really fascinated with old electro-mechanical dials from old phones. So I have got crazy idea to combine such dial with LCD and more interestingly with Sigfox connectivity.  This time I have published description on Hackster.   https://www.hackster.io/stimpoff/voice-over-sigfox-network-bbc504

Losant- Really nice IOT platform

I have tested quite a number of IOT platforms and always there was something missing or it was just over engineered. Approximately three months ago I have found Losant plaform and after few minutes I had first live data visualization. Since than there were introduced many new features and working with this plaform is really a joy.  I planned to make some article about it with some basic guide but I found that Losant guys did really nice guide how to use it with Sigfox devices, so here is t...

Sigfox based wireless water leak sensor

Roughly a year ago I have experienced the fatal error on my house plumbing system which turned my house into swimming pool. All ground floor was covered with 10cm of water and the total volume of water leaked from a broken pipe was more than 7 m3.  At that time I  hadn't installed any water leak alarm in my house what was the epic mistake. Currently, I have installed some cheap solution from eBay but it is rubbish. So I got an idea to build my own nice one based on Sigfox network.   ...

Co-Assist: Elderly people tracker watch

Document about device Sigfox antenna design

Designing Sigfox antenna for your device? I just found very nice document about antenna design for Sigfox (and other IoT ;-) devices. I know how complicated is find right balance between design of device itself and antenna inside. This is valid especially for B2C devices where antenna should be in best case invisible. So I thing that document is very helpful. http://www.sigfox.com/en/resources/white-paper/antenna-design-essentials-for-sigfox-ready-tm-devices and here is a webinar http://www.s...

Swimming pool wireless temperature sensor

I'm not really bathing type of person... But you know I have wife and daughter so small swimming pool in the garden is almost mandatory. OK when am not frequent occupant of that blue thing so I have to be at least a maintenance guy. Standard pool set offers just limited room for innovation so I decided to do something cool to be aware of unacceptable temperature of water inside and because I like cool stuff, cool beer bud definitely not cool water. You can admit that there are hundreds of swimmi...
