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. »

The wheels on the bus go round and round

…which may or may not affect the operation of our latest prototype. Only field testing will tell with any given degree of certainty. In late september, we were invited to a meeting with representatives from Telenor Reseach and the Northern Research Institute, which were on the lookout for mobile outdoors air quality sensors that could be mounted on bus rooftops in Tromsø, Norway. The sensor modules should be able to detect PM2. »

Fun with chemicals, lasers and really high voltages

Homebrew ESD Safe Component Trays. Assembling printed circuit boards is easy. You manufacture the PCB at location A, and then ship it to location B, along with some gerber files and a component list. The PCB is covered with a stencil that is used for applying solder paste. The PCB (with applied paste) is then fed into a pick and place machine that mounts the components, before it is fed into a reflow oven. »
