Let's Start Using Titles

Alas, my last day of vacation is upon me and I lament the impending return to "work".  But life goes on and I must return to my livelihood.

Before that though, I wanted to put more up about my project.  First a little animated GIF to show of the main board.

I generated this through the updated 3D viewer from http://sourceforge.net/projects/kicad-3d/ and then created the GIF on this site https://imgflip.com/images-to-gif.  I really am enjoying using KiCAD to layout schematics and PCBs.

Anyway, the main board forms the "base" of the micro-controller and has three main sections...

1. Micro-controller chip
2. Power Supply circuit
3. Female expansion headers

The micro-controller chip in my design is the popular Atmel Attiny85.  It is a small 8-pin chip that is actually quite powerful for it's small size.  

• 6 Digital I/O pins
• 4 Analog Inputs
• 3 Analog Outputs
• 8K Program Space
• 512 Byte SRAM
• 512 Byte EEPROM

The main reason I chose this was because it can behave somewhat like a "mini Arduino" which means it can leverage the huge community surrounding the larger device.  The idea is not new.  Digistump's DigiSpark and Adafruit's Trinket are based on the same chip.
