And here's mine, almost finished.

You did hall for IR ? It's not necessary to make some window for IR in the wood case.

Why not? Where did you put your IR sensor? Tbh, my remote didn't arrive yet, so I just did this blindly.

IR sensor can be placed just behind the front panel w/o hole. Remote work perfect,
I did hole in my first projects but it's not necessary.
Moreover, front panel w/o holes looks more stylish (my own opinion).

Could you please explain how IR remote operates through the wood?

You can try it.

Even though I knew the result, I just tried it to make sure

Wood - dielectric and this is all explanation.

 

[OlegSh]

Are we talking about IR or RF remote control?

 

[DrRoyal]

IR

IR

Then I don't see how does the fact that wood is dielectric help to transmit IR signal.

 

[DrRoyal]

Who told you dielectric help to transmit signal?
It doesn't prevent a signal from coming through.

 

[OlegSh]

So you are saying that wood is transparent for the spectrum of the infrared light used in remote controls?

It was your achievement

You can propose any version as per your imagination ... but it's work w/o hall.

My experience is that IR remote control does not work through the wood.

IR normally does not pass through the wood. Maybe you have a parasitic passage of reflected beams through some other opening in your construction. Put a remote in completely closed wooden box and see if it works that way.

 

[OlegSh]

Scientific literature reports that IR light penetration depth into wood is limited to some micrometers... So I totally agree with zdr. If you don't have direct or indirect (through a reflection) visibility from the source to the receiver, IR remote control will not work.

I'll make video on weekend with Apple remote - I hope I'll have a few minutes to do it.
