Hello all,
First of all, I'm not sure where to post this thread, so I put it here; if this is the wrong place, moderators please help me and move it where appropriate.
Well, I need ypur help with a little idea I have in mind.
Basically, I own a beatiful Technics SU-V9 amplifier, that is the hearth of my Hi-Fi system.
The amplifier takes the signal from a turntable and a liquid music server (Raspberry PI + Topping D10s DAC).
I do not really like the idea to have to power on three different devices every time I want to play music; even more, I really hate the idea to leave the sources powered on all time.
So, my idea was to build or buy an intelligent multi-socket adapter, with one master outlet (the amplifier), and several slave outlets, that automatically will be powered on only when the master is on.
In other world, I'd like to build a current sensing device, that drives a relay when the master device has current flowing into; that relay then will power the slave devices.
Do you know of anything already done, or, even better, do you have any project or idea for such a thing?
Thank you in advance.

Already done and available commercially.
A mains power strip where you plug your 'control unit' (Technics for example) in one specific socket.
Any load on that socket will turn on all the other sockets.
You can also get remote controlled power strips if that's more your thing.

That is what I was looking for!
Thank you very much.
Actually it is very simple and clever.
I think I will use a small 1A triac (Z103MA) driving a 230V relay; the relay then will power the slave device.
This way I can avoid the TRIAC leakage current to flow through the slave loads power supply, even when the master is powered off; I found in the past that such a current can charge the power supply internal capacitors to the point the power supply starts, and gives random power to the loads.
Z103MA has a really low leakage current (about 5uA), so it cannot switch a relay when not in use.
