cut back the four pieces of blocking behind the marquee so they don't leave shadows in the corners. looks good.
DaOld Man:
Speaker buzzing: Make sure you dont have the speaker wires running next to or wrapped around an ac current carrying cable. If not, check the cables from PC to amp, make sure both shields are good.
Do speakers buzz if you unplug the inputs to the amp?
Trackball: Im not sure, need to look at a wiring diagram. I know the optics on the trackball need + - 5vdc.
Could be a driver problem too, since it connects to usb.
ambush:
Here is the trackball connection problem broken down.
I purchased the Groovy 3" trackball http://groovygamegear.com/webstore/index.php?main_page=product_info&cPath=74&products_id=363 and the OptiWiz no-solder USB interface http://groovygamegear.com/webstore/index.php?main_page=product_info&cPath=76_85&products_id=260.
The trackball has 4 wires that come off of it. 3 of them are for motion and connect directly to the OptiWiz pin connectors.
The 4th is a green wire with a circular terminal connector. I have no idea what this does. Maybe ground? Where should it connect?
On the OptiWiz interface, there are two pin connectors that say 5v. What do I connect to these? There were no supplied cables for this.
Thanks!
TopJimmyCooks:
green wire off trackball is a ground. because TB's can generate static electricity. Not necessary for the trackball to work, I would install it only if you had a metal cp.
the six wires you have coming off the optiwiz should take care of your trackball. I think the 5V posts are only if you have something else looking for 5 volts off usb.
