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.

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

Hebrews 3:12 Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God. 13 But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin. 14 For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end;

Split Flap Display

Getting a start on my rainy weekend project.

Sneaky front...

In the 15 years I have lived here, the last chance for a taste of winter traditionally appears the first week of March and then we are in the clear.  This weekend will be the crappiest third week of March on record (for me).  Reminds me of spring in upstate NY when it would warm up just enough to bring the spring peepers and wood frogs out of hibernation.  They would begin their mating ritual with their peeping and croaking - only to get dumped on by another cold front with a foot of snow.  73,85,46,0,B

background bling...

LED indicator light sequence test for each time segment. From here I can program the LEDs to turn on and off to precisely match the timing of the stepper motor movements. 79,85,46,0,B
