Full Bathroom Remodeling (with the Help of a 3D Printer)

Posted on by

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….

This is yet another milestone on my journey to combine the Hexiwear with the Raspberry Pi: now I can send take over control of the Hexiwear with openHAB running on the Raspberry Pi:

Kinetis Lava LED Light Cube

In “openHAB RGB LED Light Cube with WS2812B and NXP Kinetis” I started experimenting Kinetis boards, a LED cube diffuser and Adafruit WS2812B NeoPixel LEDs. That worked well, but I was not to very happy about the visual effect. So here is my next version: I wanted to have control over each side of the cube. For this I have built a cube inside the cube with a 3D printed structure:

From my earlier work to use the NXP Kinetis with openHAB (see “Controlling NXP Freedom Board RGB LED with openHAB and Raspberry Pi“) it was only a small step to control a 20x20x20 cm light cube with 256 Adafruit WS2812 NeoPixels:

Controlling NXP Freedom Board RGB LED with openHAB and Raspberry Pi

In “Blinky LED with openHAB on Raspberry Pi” I have used openHAB on a Raspberry Pi to control an LED attached to the Pi, and in “Controlling NXP Freedom Board RGB LED with openHAB and Raspberry Pi” I have explored how to connect a NXP Freedom Board over USB CDC to the Raspberry Pi. In this article I’m going to combine both: to control the LED on a NXP Freedom board remotely with openHAB on the Raspberry Pi.

In my earlier post I showed how I have installed the open source openHAB home automation system (see “Installing openHAB Home Automation on Raspberry Pi“). In this post I show how to control a local LED on the Raspberry Pi with openHAB home automation system: how to control any GPIO pin on the Raspberry Pi from remote:

In “Installing openHAB Home Automation on Raspberry Pi” I have set up openHAB on a Raspberry Pi 2. But when I reboot it, I need to start openHAB manually. This post is about how to start openHAB automatically after a reboot.

Installing openHAB Home Automation on Raspberry Pi

I’m currently building a home automation project around Raspberry Pi: I want to be able to monitor and control things like the lights, garage doors and the heating system both at home and from remote. I already have added a touch screen to one of my Raspberry Pi 2 computers (see “Adding a Touch LCD to the Raspberry Pi 2“). This article is about how to install the openHAB on that Raspberry so it can be the brain of the automation system.
