Let's start with the BOM:

PRINTED PART:
Print all the STL files:

1 x ButtonHolder-1005.stl
1 x logoPen-1005.stl
1 x ingranaggioGrande-1005.stl
1 x ingranaggioPiccolo-1005.stl
1 x FlapStaffaLibera-1005.stl
1 x FlapStaffaMotore-1005.stl
2 x NBottom-1005.stl
2 x Ntop-1005.stl
2 x FlapRuota-1005.stl

Threaded rod:

4 x M8x250  
3 x M8x150
1 x M8x180

Other:
100 x M8 nuts
100 x m8 washers
40 x iron wire diameter= 1 mm, length= 95 mm
2 x 608 "roller skate" bearings
6 x M3x15mm bolt

ELECTRONICS:
1 x ARDUINO UNO
1 x pololu stepper driver A4988
1 x stepper motor (eg. 35BYG104)
1 x Arduino Proto Shield
1 x LED
1 x push button 12x12 mm
1 x 10kOhm  resistor
1 x 320Ohm resistor



Step 2: Build the structure

Now you can build the structure.
In yellow the printed parts and in gray the threaded rod.

Fix the part to the threaded rod with washers and nuts.

Step 3: Build the rotor

Picture of Build the rotor
To build the rotor use the 190 mm M8 threaded rod.
Put each component in oder and when finished close the nuts.

In the picture you can see:
- the gear in red
- the bearings in green
- the two weels with the holes for the iron wire 

You can choose not to use a nut between the gear and the wheel but 3 or 4 washers.

whoa that's way cool, do you think it possible to turn it into a clock?
bissaorboea (author)  liquidhandwash1 year ago
yes, the original Split Flap display technology was used for clock too.


Didn't Marty McFly have one of those in BTTF?
This would be perfect for oblique strategy cards.

I don't see the sketch uploaded here. Am I missing it somewhere?
bissaorboea (author)  Tomdf1 year ago
Opss... A .zip file with the code is now uploaded.
Sweet, thanks
its a random rolodex :D
pretty sweet!

You could turn this into a Mutoscope. Just come up with a Steampunk and like case and you got it !
Don't need a machine !
"Should I ask for a raise ?" : YES !
"Should I call this cute Guy ?" : YES !
"Should I sell ?" : YES ?
"Should I buy a boat with the money and live in a Pacific paradise with the cute guy and without my boss ever after" ?" : YES !
Simple !…

Love your idea !
Thanks for sharing.

That is too cool! Nicework
That Arduino case in the pictures is pretty slick too, did you create it? I'd sure like to get my hands on those files.
bissaorboea (author)  Tomdf1 year ago
No, I find it on the internet, google "Arduino Cases by variador".

Hahaha! Very cool idea!
I also like very much the little Gecko on top! Nice touch. :)
