Can I learn anything useful from the circuit board of a nonfunctional infrared remote control? [more inside]
Hello. I have lost my remote for my Sylvania SRT 2319 and am trying to program my Time Warner Universal remote to work with it. I have found the code and the remote will power on and off the TV but it will not control any other features. Any time I press the channel key or a number key the CBL (cable) device button blinks, like it's not registering as a TV button. Does that make sense? What can I do?
Can I purchase, or easily make a bluetooth keychain device which I can detect with my laptop? [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]
