I was brainstorming retarded, ridiculous, and unheard of general hardware ideas and thought I might share this one with you all and see what you guys think
I need a hardware project otherwise I'm going to go insane with all this web development
So how hard would it be to make an LED marquee and connect it to an 84P to allow the user to input any message and have it display on the LED marquee?
Lets start simple now, of course. Here are a few methods I thought of to make this possible.
Option 1
Build a 12 x 112 LED Marquee, and simply have it display what ever is on the calculator's screen. Basically same concept as a dual monitor system. So, in theory, this would display this first two lines on an 84p's home screen.
Option 2
Build an LED Marquee, and have the calculator "upload" a message on to the Marquee that would then display the message constantly unless switched off. The benefit of this would be that you didn't have to have the calculator set up. The bad thing is, I assume, it would require a little more advanced architechture involving microcontrollers and other small chips (but I suppose the first idea would as well... unless the ASM program sending the information to the LED Marquee was written to handle the Marquee completely on its own, instead of sending it raw data for the Marquee to interpret itself.)
I apologize if any part of this post is confusing or not easily understood. I'm partially asleep right now, so forgive me hehe

Might be of use in this situation, might not...
