@@montaelkins2816 About as well as it can be, my friend! I'm making like Chumbawamba over here. I actually just finished my own clock project a few weeks ago, too!
@@AirborneSurfer That figures. Our project thoughts always seemed to go down the same lines :) I'm really busy now working two jobs so my project making time is miniscule.
Thanks! I consider that quite a compliment. I build these project solely for my own entertainment. You might be able to find someone willing to copy my design. I'd be totally fine with that and they can use the video as a reference :)
Huh. I was about to blame that random step issue on floating gates on the driver inputs, but I just checked my stock of those cheapo stepper drivers and mine use Darlington pairs of BJTs (ULN2003A). Is that the same setup your drivers use?
I'm using the same driver chip. I think it's that I'm storing the number of steps I've taken in EEPROM when I shut it down, but which step in the rotating sequence I'm on, so depending on which step the motor was left in, my first step may be "random". I'm also using the small adjustment buttons for fine adjustments of the pointer positions.
Hiya Larry! I'm using cheap ULN2003 boards (typically sold for "use with Arduinos). The board AND the stepper motor are available for < $2.00 if you look in the right places.
The drivers are just Darlington-pair NPN BJTs -- hardly worth of being called a "driver" at all. They can source 500mA at 50V, which is about how much you can get out of your favorite "jellybean" discrete parts -- so you can literally build one yourself. The only other bits on the board are LEDs and current-limiter resistors.
I had thought all the other gearing removed was reduction ? not sure, but if so, or if could have reoriented the gearing to be reduction and drive that way originally, oh well.
12pm its light out....12am it's dark....u almost had me convinced otherwise lol. Cool video thanks

LOL MOAR POWA
Yay! Coke & Strippers is back!
Thanks Dude. I hope the new world is at least treating you OK.

Oh, hey. I remember this guy!
The rumors of my death have been marginally exaggerated :)
This is awesome! Would you make one I could buy as a gift? Or you just make this as a one off?

It's beautiful
Love this. What stepper motor drivers are you using?

Do you have a video on how to wire up a meter as a lamp ?
No. But you might find some other interesting projects of mine
Make a 6 digit one with seconds
