This is about one of my ‘long running projects’: I happily can report that the missing last piece has been installed after 16 months from the start of the project: the ‘3D-Printed-Supported-Driftwood-Bath-Tub-Shower-Gel-Holder’ 🙂 :
This is the ‘official finish’ of a complete bathroom renovation and remodeling. It has been a joint project with the help of friends, contractors, my family and my brother in law (who is an outstanding carpenter and cabinetmaker), plus the Ultimaker2 3D printer which contributed many ‘background and hidden’ features.
I invite you to a virtual time travel. I hope you enjoy it and get inspired….
LoRa and LoRaWAN is getting the de-facto wireless IoT network in my area. No surprise that traditional telecom providers like Swisscom trying to monetize the ‘Internet of Things’ area. Luckily there is an open and free alternative: https://www.thethingsnetwork.org/. Volunteers, enthusiasts and members in the different TTN communities build gateways and offer free LoRaWAN network access. I wanted to contribute to that grassroots movement with building my gateway, providing LoRaWAN access to my neighborhood.
Need a quick way how to attach a LED, a push button and two resistors to the Raspberry Pi header? One way is to use some ‘flying’ wires. Or to use three pieces of lasercut plywood for a nice looking Raspy extension board:
BLE (Bluetooth Low Energy) sensor devices like the Hexiwear are great, but they cannot store a large amount of data. For a research project I have to collect data from many BLE devices for later processing. What I’m using is a Python script running on the Raspberry Pi which collects the data and stores it on a file:

The Raspberry Pi is a versatile mini computer: as such I can use it with USB keyboard, mouse and HDMI LCD monitor. But having multiple keyboards and mouse on my desktop is not my thing: somehow I always grab the wrong one. So what I prefer is to run the Raspberry with VNC (Virtual Network Computing). That way I have the Linux GUI as a window on my normal desktop, and no messing up with keyboards and mouse 🙂 :
