you shouldn't have to if you calculate the appropriate values for the resistors

I spent about an hour and a half soldering transistors, and resistors, and wiring it all up, and then realized that I stupidly grabbed the wrong box of transistors out of my parts drawer. I used NPN transistors by accident instead of PNP :oops:

Might think about buying yourself a solderless ...

Why won't your drawing work?

you will need a couple of resistors for each transistor to make it work. You could leave out the resistors and see if the circuit works properly, but no guarantees. R1 (from the site I linked) brings the transistor into its saturation state. R2 isn't required, but it ...

After thinking about it, I realized that my diagram won't work quite right as-is, but it's close, you're going to need to modify it a bit. Look here on what you will need to do to modify it.

Please excuse the horrible drawing, but this might work for you

This has the guitar string as ground and uses pnp resistors. If this doesn't work, then I guess you'd have to make the string positive and use npn transistors, but that doesn ...

again, correct me if I'm wrong here, but when you say and the buttons don't actually go to the ground, they go to a glop top or something. So each button has two unique contacts. it sounds like you already have a controller that you want to wire your guitar into. Are you certain that the different ...

Well, I know some malware install their own drivers for optical drives and removing it can break the system's ability to even see the drive at all. My suggestion would be to just back up anything your coworker needs to keep and reinstall windows.

It might be nice to have a little better description of what you're trying to do. I'm assuming you're building a guitar hero controller and you want to wire it to either a USB controller or a normal playstation 2 controller, is this right?

What are you trying to do with this controller, are you ...

Now where could I buy printable silkscreen? :P
use a laser printer (not inkjet) to print on the shiny paper found in magazines, it will iron off onto your board and the etching solution won't eat through it (unless you let it etch for way too long.)

Also, solder won't stick to the board. Is this normal? In fact... solder wont stick to a lot of things I try to solder.

There is probably a coating on several parts of the board that you will have to scratch off in order to solder to it. Also, when soldering, don't heat up the solder with your ...

My personal suggestion would be to just buy another GBO off of ebay to hack apart for the controls. If destroying the controls of a working GBO seems offensive to you, there are usually one or two auctions for broken ones (there is a broken one for sale right now, but it also happens to be more ...

They had some at the local petco (fridley, MN) when I was there a couple of weeks ago. I'm not certain, but I think they were $4-5.

I would disagree, there are many advantages of using linux in certain situations, but unlike some people, I don't think it's appropriate in all situations.
