Need help reading ring generator circuit
I'm planning a carputer based around an old laptop with WOR. I've taken a look at a lot of the options to remotely turn it on, and the easiest option I think I have is to build a phone ring generator, and just plug it into the modem port when I dock my laptop in the car.
I'm not interested in a docking station, and I don't want to open up my laptop and solder. I want to find a solution that can be upgraded with my laptop. IE: setup a touchscreen, DC power source, wifi antenna, gps mouse, and this WOR 'switch'.
I believe I found a circuit diagram that can do what I want. Basically I'm imagining a switch that triggers this black box, which in turn triggers the WOR circuit of the laptop.
Now I haven't looked at circuit diagrams since 8th grade, so I can only understand this diagram at a basic level.
I like the 9V solution because I don't have to run more wires around to my car circuit. I could just run 6 D cells in series, put it in a tupperware, hide it somewhere and call it a day.
Now my questions, as it's my first homebrew circuit:
1. will any blank circuit board (ala ratshack) work as a base?
2. Where's the negative side of the 9V source hookup?
3. what's with the 120V part, on the right side?
4. what does the curly q mean, next to the +9V? An inductor? why?
5. all those capacitors are grounded...but to what?
6. all those NOT logic gates (inverters?) have numbers in them, what do they mean?
7. what does it mean to have an arrow to the 50k resistor on the bottom-left?
8. is that gap, with the sideways 'T' on the top-left where the push-switch goes?
9. am I in over my head? Is this way to hard for a noob? etc, etc...
Thanks in advance.
