gotta have faith...

Hebrews 6:11 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.

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

Hall effect...

Testing out a hall effect sensor. There is a small magnet embedded in the rotating disk that the sensor reacts to when it is directly in front of the sensor causing a digital signal to be sent to the micro controller. This is used to find "home" for the stepper motor when it is powered up - a starting point for it to move on from to reach precise degrees of rotation in order to display specific numbers or letters. 84,91,47,0,B

Existential Crisis...

Waiting to see why my Facebook account was disabled 

and how another name got associated with it.  

I had all the correct privacy settings in place 

to avoid this exact kind of problem.

flappin'

I have always been fond of split flap displays - especially the arrival/departure boards I used to see in train stations and airports. Split-flap mechanical signs are sadly a relic of a bygone era. The famous, clacking boards were once used all over the world, but advances in technology have retired most of them in favor of boring digital displays (the epic split flap displays in NYC's Grand Central Terminal were retired and replaced in 2019). Thought I would try my hand at using my 3D printer to make one. This is just a first test to tweak the mechanics of one segment. The model I posted on Friday did not run smoothly at all, so I am trying a different one. It took about 12 hours to print out all the parts and I had to make several small changes to get it to run smoothly. I have some hall effect sensors and magnets coming this week so I can try this out with some Arduino code I found on YouTube. This is the plan I am following... 61,68,41,0,B
