The basil speaks to me

Intro Part of my home automation system is monitoring the well-being of various other non-human species around the house. So i started with the plants. Since they are mostly fixed creatures and generally require only water input from humans, monitoring the soil humidity is a good start. How There are quite a few ways to measure how much water is in the soil, some of them described here. But the internet shops are full of… Continue reading

10002 Control panel horror

Intro I have been making some slow progress with my smart home project. I have completed a small assembly run of motion sensors, there are plenty of things that are working and I shifted some focus on making a control panel. What I normally want is a control interface that works well from both a PC and a phone. Bonus if it can look nice on a tablet to have one real control panel on… Continue reading

10002 Short assembly run

Brief progress It is quite clear that my smart home project is going quite slow. It is not that I spent a lot a time on it, but that I have been pretty busy with other life things. But it is moving again now. Check out another batch of assembly. Motion sensors assembly Once I settled on the type of motion sensor and case, I designed some sensor PCBs .

As a… Continue reading

They are selling complete kits or you can build one yourself from the plans that are provided. I was missing only a few servos and the 3D printed pieces, so I quickly decided to build one.… Continue reading

Simple audio mixer

Intro I have one low cost TPA3116 amplifier which has got more usage than I initially thought. I ended up using it in the living room, it provides enough power and burns only 0.7W from the mains while ON, with no signal. So low that I don’t need to worry about shutting it down when there is no signal, so it’s on all the time. So on to the problem: I need to use it with… Continue reading

10002 Progress

This article is part of my 1000² Smart Home project. Check out the Architecture and Software and then move on to Hardware. An most importantly, check the Lessons learned and why I did what I did. There are already some first results, connecting all parts of the system. Progress Finally, enough pieces of the puzzle are starting to fit together in my Smart Home project, so that I can have some end to end functionality: press a button here… Continue reading
