Finding T F L

Really used a lot of brain cells to get to this point with the split flap display - including a bit of math. I am using the standard cheap 5 VDC 28BYJ-48 stepper motor but it is geared down a little too much for my liking with 2048 steps per full revolution. These are only a few dollars apiece because they are manufactured by the millions - DVD drives, motion cameras, AC units (for moving louvers), and many other related gadgets all use this or comparable motors. Ordered the slightly more expensive Adafuit version to try with this. It is geared to be only 512 steps per full revolution. This is still a work in progress and if it continues to go well (and holds my interest long enough), I will make some design changes and use vinyl numbers and letters for the characters instead of a sloppy Sharpee. 83,90,51,0,W
