So basically at this point, I have both digital and analog time being displayed along with velocity. I wrote the entire program in C language. Right now I have the system being triggered 120 times per cycle. I don’t think I can get it down to once per cycle but believe 8 times is possible. Reason being the Motorola HC12 gives out unreliable readings at such low frequencies.

At this point I’m trying to think of what else to put on it. I could put temperature on it but that seems easy. Eventually, I would like to make it controllable by a universal remote control, just not at this point in time. I was thinking of some kind of animation. Maybe have it write out letters in cursive…the letter would just not “appear” but actually be written out like someone is actually penning it on the wheel. I wrote out the array needed for one letter and it is about a page…no kidding. I didn’t even test it yet.

I’m racking my brain how to do the cursive thing. I have allotted a space of 16x120 LEDs wide for it. What I am doing now is…well, I draw the letter on my wheel grid and then painstakingly code each position into the array. The final product looks like a bunch of movie frames.

I have three factors going on here…revolution number, slot number, and data to place in that slot. So for revolution #5, I want FE in slot 56, 14 in slot 57, 1A in slot 58, 6F in slot 62, etc. For revolution #6 slot and data numbers would all but be completely changed.
