That's really neat, mnem! I think I have the electronics from an old floor-standing fan I scrapped some time ago. I believe it was IR controlled. So, I might have a chance of making something similar.

BTW, to do go/no-go checks of IR remotes, I usually use my phone's camera to see if the IR LED blinks.

You can have a load of fun with a photodiode, opamp and a DS1054Z. I built a simple photodiode amp with a LM358 and BPV11.  Record the power button waveform and load it into the DDS (DG1022Z) then play it back through a 2n7000 and IR LED pointed at the TV slyly with a simple trigger set up wired to a push button with a pull up.

Kids playing up, first warning, second warning clicked fingers and TV goes off.

They nearly fell off the couch in surprise, especially the one holding the remote control.

iPhone camera is no good for this as it has an IR filter on it.

Samsung phones work a treat as an IR detector, I often use mine for that purpose, another score for Android in the TE arena.

Good to see England in the QFs after all this time, let's hope we continue the momentum and bring it home again.

From mobile device so predictive text might have struck again [emoji83]

I suffered total and sudden computer failure on the Internet-capable part of my IT.
