Hey everyone, I'm new to this list and to lists in general and I hope I am sending this to the right place.

I am working on the TI85 light show thingy and I am adding some awesome features to it that the guy who designed it (I forgot who) diddn't think of.

1- the circut drives eight LEDs, why can't it drive a 7-segment display? (which is 8 LEDs with the dot) In my lightshow there are 8 LEDs and a 7-segment display selectable with a switch. If you have ever played skeeball (or something) at a Chuck E Cheese's you know that a 7-segment display can do some pretty cool effects.

2-The tiny blue box that holds all the lightshow circutry also has a 9 pin serial port on it, pin one is common and the other 8 pins are + out at led voltage so if you wanted to build another box with relays and IR LEDs/IR phototransistors or optoisolators and have the calculator control big incandecent lights you don't need to build another lightshow thingy, you just plug it in.

I havn't finished it yet, tho. I need to find a LM7805 9v to 5v regulator. does anyone have any suggestions?
