Thanks, Larry!

Yeah, maybe for YOU!! For dolts like me, we need component values and 
EVERYTHING spelled out. I know virtually nothing about resistor 
values, etc. 

I poked around the internet, looking for generic pre-assembled 
joysticks, but all I could find were Gaming joysticks with finger 
grips. Me, I just want a simple, unadorned long pole with X and Y 
axis. Something small too, that can just sit on the edge of my 
keyboard.

Anyway, if it's possible to actually attach values to the various 
components, and point in the direction of a simple, small joystick, 
I'd be grateful....

Thanks, Larry!
