Mooi maakproject: 360º Camera setup

Klik om af te spelen ▶ Bekijk op YouTube Via Adafruit kwam ik bovenstaande video van KaneFernandes Design, een 19 jarige student Product Design aan de Middlesex Universiteit in London. De titel is een beetje misleidend, er staat “360º Smartphone Camera Drone Rig using Arduino Uno & XBEE“, er wordt niet echt gebruik gemaakt van een drone, maar van de motor + propellor […]

LoRaWAN with LoPy and KPN + Loggly

In the Netherlands, KPN was the first to offer nationwide coverage of a IoT network based on LoRaWAN. You can read about my first tests using their Network in combination with the Marvin node in this post. Unlike with the IoT network that for example is currently being rolled out by T-Mobile, which uses NB-IoT and different hardware than The Things Network (TTN), […]

TTN + MQTT + Node-RED + MySQL = local backup of your LoRaWAN data

Now that Alex explained everyone how to use MQTT in combination with the LoPy, I thought it was time to show some more advanced uses of MQTT in case you still had no idea why you would bother learning to understand it. The nice thing about MQTT (MQ Telemetry Transport or Message Queue Telemetry Transport) as a protocol, is that it […]

Welke programmeertalen moeten leerlingen/studenten kennen?

Dus een vraag als “Welke programmeertalen zouden onze leerlingen/studenten moeten kennen?” (bron) is niet helemaal zonder risico. Immers, je moet dan gaan nadenken over het doel dat je daarmee hebt. Wil je ze leren programmeren? Of juist coderen? Of software ontwikkelen? Ik ga niet […]

Connect the Puck.js to The Things Network using a Pycom LoPy

I still wasn’t out of “what if…” scenario’s for the devices I had been playing with in relation to The Things Network / LoRaWAN. Because, although I had used the WiFi (and of course LoRA) capabilities of the LoPy a lot, I had not yet played with its BLE (Bluetooth Low Energy) capabilities. For that I needed something else that could […]
