I've pulled an RF modulator out of an old VCR, but I don't know what some of the pins are for on the unit. Help me wire it up to modulate a composite video signal. [more inside]

I'd like to trigger a relay that momentarily closes a switch based on the voltage of another wire. Maybe. I think. Please help me with this basic (I hope) electronics project. [more inside]

I have an old Pair of Zenith Allegro speakers (50-watt, 8-ohm) with pre-attached cables and RCA-style plugs (male) for connecting to the stereo. I'd like to use them with a more modern receiver (50-watt max, 8-ohm) that accepts straight wire from the stereo; should I just lop off the ends and wire them in, or is there a better method? Also, can I use them with a >50-watt stereo if I keep the volume down, or is that just bad?
