Rotating monitor construction *Project finished*
DaOld Man:
Its really not that hard to follow what I am doing here, except that my drawings are crappy, plus my cam pics are not good at all up close, unless I use very high settings, then the pics are too big to post.
It might help if you know what the symbols I draw mean.
The schematic drawings are just shortcut symbols that make drawing a circuit easier.
Look at the example drawing I attached.
You can see that the top would be a lot easier to draw (freehand anyway, both suck in Paint, but you can copy and paste.)
You just need to learn what the symbols mean.
DaOld Man:
Sorry I forgot this in my last post:
Thanks for the kind comments javeryh!
Here is a site that has a pretty neat description of schematic symbols:
http://www.aaroncake.net/electronics/schem.htm
Pull the horizontal divider down, then in the box at the top, place your mouse on a symbol, what it is will appear in the box below it.
Im sure there are thousands of websites that can teach you, just google schematic symbols.
But if all you want to do is build a certain circuit, you just need to learn the symbols used in it. Please feel free to ask me anything about any of my drawings.
Im not above making mistakes too, so if some of your experienced guys see a mess-up, please alert me.
HaRuMaN:
Shouldn't you be using the correct symbol for a resistor then?

DaOld Man:
Resistors are drawn both as a rectangle and the -VVV- drawing you drew.
If I freehand, I usually draw it like you did, but using paint or most any CAD type drawing, it is harder to draw than the rectangle.
But if you look it up, most designers these days use the long rectangle.
I try to label all my parts, such as R1 is resistor 1, which should help to identify it.

I connected the inputs to ground through a 470 ohm resistor.

Doh! I knew I must have missed something when I put that site together. I must have spaced when I drew those diagrams, sorry. Yes, you definitely need to tie the inputs low - I used 4.7k resistors between the input pins and ground. I must have spaced when I drew those diagrams, sorry. (At least I mentioned it, sort of, on the what you need page.) I'll be sure to update that site.
Thanks for pointing that out!
BTW, DaOld Man, if your ISP doesn't supply you with web space, I can set you up with some site space on the server I'm using, just let me know.
