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. »

The First Industrial Evolution

“We’ve got to pause and ask ourselves: How much clean air do we need?” Lee Iacocca Clean air Feeling drowsy ? Got a headache ? Hard to concentrate ? No worries. Check the CO2 levels in the office. If they are on the high side, go open a window and breathe some fresh air - or yell at the janitor in order to get him/her to fix the air conditioning. »

The "T" in IoT

A wise man once said: “The Internet of Things has a profound lack of things”. Well, this is true, so let’s push the state of IoT a small step in the right direction, by adding some things. A “thing” doesn’t necessarily imply something new and innovative. It doesn’t have to be disruptive either. Significant value can be added in a business domain by simply IoT enabling existing devices - like, in this example, pinball or vending machines. »

The LLC (Little LoRa Collider)

Some things are notoriously hard to test. Since we’re not designing our own gateway or packet forwarder (yet…), we end up having this third party “thing” between our beautiful Congress backend and our elegant EE02 LoRa modules. This “thing” being a LoRa gateway, which behaviour we simply have to trust. It should (in order to claim to be a LoRa gateway) reliably implement all the happy path scenarios needed for a successful LoRa deployment. »
