I’m the lucky owner of a Devialet Expert Pro 250
(which started as the D Premier many moons ago) driving a pair of Martin Logan CLX Art.
(Yes, it’s as good as the many raving reviews say. If you have to chance to buy one,
Now that we have a nice enclosure, time to put everything inside.
For the enclosure I wanted something special and not some boring metal or 3D printed
box most projects end up in (if at all). For this I found inspiration with
DIY Perks on YouTube.
Since it’s a bit hard to get a dedicated wire into my house just to transfer the measurements to where I want to see them, I decided to try out a wireless solution. I ended up using the very inexpensive 433 MHz RF modules for Arduino which seems to work well for me since the signal only has to cover a distance of a few meters. On the other hand, the sender will be located below ground level and there is a metal lid above it as well that can block the signal.
Since an Arduino will be inside the rainwater tank, I will need some electricity
there as well. I could exclude using batteries since an Arduino isn’t exactly low
power and I needed to power some sensors as well.
