My most recent project is the Pixel Clock - a clock displayed on a bright and colorful 8x8 RGB display. I'll be honest - I first got the display because it was so cool, then I decided to make something useful out of it :-)
The looks must be clean and non obtrusive, this way the pixels come out better. The device must be useful, but it must also be something that you can play with. This in combination with a good interface. As we speak I've come up with the following (so far):
- Size is about 70x70x30mm (excluding button)
- The control is a rotary encoder (endless rotation) with a button
- 3D printed case
- Prototype PCB using a Cyclone PCB factory
- ATMEGA328 with Arduino software
- Clock using DS3231 realtime clock module
- All Open Source hardware + software (CC BY-NC 3.0).
You can find all used hardware and software on GitHub.
During prototyping I made some progress pics. Oh yes, you have to see it with your own eyes. It looks way better than in real life!
It is the first time that I take a project beyond prototyping, this time (pun intended) I'm making it ready for manufacturing. To be continued...
