[QUOTE="a33, post: 977486, member: 332642"] Well, I guessed you had the 8 relais also lying around...... :). No real problem for you to put them together I would think? ;) No, I don't have a simple solution. I first thought: do you really need the relais, to separate the circuits? Or can you switch the remote with the voltage and current of the receiver-loopthrough? I guess pushing a button of a remote sends a voltage/ small current to the chip of the remote. But then, that could be leading 13 or 18 volts to a 3 to 5 volt-max? chip in the remote; which means danger. I thought: Can't you simply use a capacitor of (say) 1uF (or 10uF?) and a resistor and maybe a protecting zener; to let curent through, till capacitor is full (and extra resistor, to let it slowly discharge)? Could work, but I don't know what value resistor you would need, not to blow up the chip of the remote. Another safer option would be to open up the diseqc switch, as the regulator IC of that works on 5 volts; so the 8 outputs of that (leading to the switching transistors inside the diseqc switch) would all be below 5 volts. Other line of thought: I remember something about 'mono-stable flipflops' and 'bi-stable flipflops' in logic IC's. Then you would have logic/digital switching. Or just try the capacitor-solution in your existing interface? I haven't though about how to connect the discharging resistor in your remote, though. But, these are just lines of thought. And I'm no expert. But watching interesting DIY-projects like yours make my thoughts wandering a bit, too... :) Just thought-wandering is nice; I leave the trying and sweating to others..... ;) greetz, a33 [/QUOTE]
