A working prototype - Hourglass Project - Part 4

Read Part 3 first The summary update is that I have a working hourglass prototype that delivers the basic requirements. Since the last update, the code changed considerably. Certain nice object-oriented concepts went away, bit packing and elimination of anything that can be replaced or reused from existing objects resulted in the code footprint to shrink to less than half the original size that was working on the PC. This allowed for a successful compile and upload to Arduino. ...

Hourglass project - Part 1

Started working on a new mini-project to build an hourglass using cascaded led matrix displays driven by max7219s and an arduino with some kind of a gravity sensor on it. What makes this project interesting is I intend to make it imitate physical falling of sand particles under gravity. Initial challenge is to have a prototype housing. As I intend to imitate a real object I cannot simply place components on a breadboard and lay it flat. ...
