GETULA

I used the digits to create a 2020 goodbye display ...

More progress on making the module look nice and figuring out a way to make a combination of 4 modules

The next step was to figure out one complete module with the electronics fixed in the module itself so that it is completely independent. 

Initial prototypes:

The first several prototypes were used to figure out the working of the chain . I tried various configurations of 3d prints to get the friction right and finally figured out to make it with o rings in the joints.
