Hello, I just built this little device: **broken link removed**
but on the schematic, it shows the variable resistor connected. The problem is, there is 2 wires, but 3 leads on the variable resistor. I used a multimeter, and found 2 pins to connect it to, where I get anywhere from 0 -10K like it should. Do I still need to connect to the 3rd lead to make it work properly? I see it does show another wire in the schematic.
Also, I plugged everything in, and tested with camera. Infrared light is emitting from the device, so I know it works. Yet I cant get it to block TV signals. is there a device I can build, or a way to see what frequency is being emitted from my device? Maybe a multimeter or something, because I heard TV usually emit about 38Hz or something?
