can be mixed up, and even worth it.
As for the standards, it is a European RC5, or SONY (no longer European), we can easily generate in BASCOM for AVRow.
for example, the Cyfra + remote control works at the address 10 (I checked). power on / off (red button for standby) has the command number 12.
maybe our neighbor's equipment has some other standard, so maybe we will have to "rip" orders on foot, and then play them like from a tape recorder. The disadvantage of such a solution: you have to somehow lead the neighbor to a neighbor and "record" orders for something, or go to her with this baby and click a little and then silently spill the orders out.
behind the AVR we fasten some more specific amplifier on transistors (remember that there is 36kHz modulation here, so the signal should have relatively sharp edges behind this amplifier).
such something in gusts takes a lot of current, so let's provide a good power supply (continuous current can be small, in the end it is only short packets are).
ir diodes ?? you can combine several narrow-angle pieces, remembering that there should be some sensible convergence (not each in the other direction, but all of them into one point, then we will gain some specific focus).
I think that's it;]
have a nice blinding home (and someone else's) RTV equipment.
And he can do with an ordinary universal remote ?? Because I'm 11 years old and I don't understand patterns 
Say if he can do it ??
and as for "dazzling" it can blind you even forever, in the end it is a laser no matter that the IR should therefore give it a small current for safety purposes
