By lockable antenna is to be possible interference as possible disappear, only the lack of integration of existing IR inputs I'd seen as a negative point, but electronically gifted can certainly here with a few tricks resolve this problem, I have a resorted sentence optocouplers and appropriate plugs from the electronics store, and a few unäuffälligen strands and behold, you have this glue does not stick to the sensitive plastic parts, even if they easily dissolve again, more beautiful it looks but when everything behind is stored and connected to the device, because then no unsightly cable and IR transmitter front of the device depends, as most newer devices have an IR input, which can be usually connected to a photo-sensitive diode, without complicated electronic ballast directly to the optocoupler can be connected, but as already mentioned, here you should already have electronic knowledge, a novice or hobbyist should not make this better, because here too valuable electronics can be destroyed and when it will be only the optocoupler, which is highly hunts, the electronics thanks it is not always an immediate, often it may take a bit until it begins to smoke and stink. ;)
