I have finally decided to enter the 3D printing bandwagon. Having room for more hardware have always been the main inhibiting factor for not having done it longer ago. But with a little tidying up of the available space the impossible eventually became a reality. At least that was my reasoning, and the selection of a small resin printer seemed like an interesting choice in that respect, at least in what concerns the space occupied by the device itself.

When you decide to setup your own infrastructure in order to depend less on cloud providers, whether it be for saving money (depending on what you will be doing) or just for the sake of improving the technical knowledge, having more control, or both, you know you will be flying solo, at least to some extent.

With a project of this type, the hardware preparation is just the tip of the iceberg. It was thoroughly explained in the last post, despite one last change still being pending. What lacks is basically the addition of a resistive touch panel to the front of the screen, in order not to depend on the mouse as a pointer/input device. The panel is still somewhere between China and my location..
The first aspect that I found important to cover, now that I had this Android based kiosk up and running, was the ability to remote control it and launch arbitrary applications and services on startup.

The sense of smell is an amazing function in vertebrate animals. Even the human nose, which is not particularly notable in comparison with other animals, is fascinating in its sensitivity to trace amounts of a large variety of substances. It has a level of selectivity and capability of distinguishing between different kinds of smells, which is very difficult to match by even the most sophisticated artificial sensors.
Having as the main motivation the enrichment of the IoT gadgetry sitting around in my house (and eventually fill up an entire 192.168.1.1/24 network address range), I found that (after the motion and entrance detection device), an interesting device to invest time on would be something capable of sensing multiple air quality parameters at the same time.

Building a kick-ass home automation by reflashing the Sonoff devices with Tasmota and getting it all working with hass.io
In spite of all the concerns that can arise from bringing smart/connected devices to the place where you expect personal privacy to exist, the convenience of having these ends up speaking louder overall..
It all started with having a set of unrelated devices in the house, each featuring connectivity and some cloud-based features provided by the vendor. This is the case for the Xiaomi Rockrobo vacuum cleaner, the Sonoff switches, the multimedia devices such as the TV set (an LG smartTV), and also the Google Chromecast and Assistant devices.
