Making sense out of nonsense

One of the first thing we found necessary after we created our NB-IoT platform, was fancy graphs. Because you know, people like graphs. It also helps as a sanity check to see that your data makes sense graphically. There was only one problem, Tm9zeSBsaXR0bGUgYmFzdGFyZCBhcmVuJ3QgeW91Pw== doesn't really translate well into a graph. »

Stayin' Alive

The IoT will have a great impact on the economy by transforming many enterprises into digital businesses and facilitating new business models, improving efficiency and increasing employee and customer engagement. Gartner, Inc.[1] Now that the heavy lifting has been done, the only missing pieces of the puzzle that is world domination, are - engineers that can build the darn things. However, the ways in which enterprises can actualize any benefits will be diverse and, in some cases, painful. »

The Chemistry of Powder and Explosives...

…does not stop when the visual effects subside. In order to make fireworks displays more interesting, chemicals are added to the propellant / powder mix. Igniting these mixtures produce varius incandescent and luminous effects during combustion. Byproducts from the chemical reactions that take place are areosols and a cocktail of more or less toxic gases. Typical compounds that are found in the aerosols are: Aluminium oxide, ammonium carbonate, Antimony(III) oxide, barium carbonate, barium sulphate, Bismuth(III) oxide, carbon, Copper(II) oxide, Iron(III) oxide, Magnesium oxide, potassium chloride, Potassium oxide, Potassium carbonate, Potassium nitrate, Potassium sulfate, Potassium sulfide, Potassium sulfite, Potassium thiocyanate, Strontium carbonate, Strontium sulfate, Sulphur, Titanium(II) oxide [1] - in order to name a few. »

Let's start a conversation

A feature we had to sacrifice on the “getting done in time” altar was the downstream messaging (ie sending messages to the devices, not just receiving). We had a clear idea on how we should do it, but our main focus was to get the essentials up and running so we had to postpone it a bit. As with any LPWAN technology the first thing you’ll try is to get bytes through the system, then something slightly more useful like monitoring data but after a while you realise that you’ll need downstream messaging to really make it a useful technology. »

Arduino library for NB-IoT breakout

One of our latest projects is a breakout board for the uBlox SARA N2 module. The breakout itself isn’t very exciting – you’ve got a voltage regulator, uFl connector for the antenna, a sim chip, a reset button and the module itself. If you are anything like us you probaly want to pull out your little teal friend, aka “the Arduino” and test it out quickly before deciding to do anything further, preferrably without having to fiddle too much with AT command parsing. »
