The current design is a functional Beeping and Blinking Business card Badge, but there are a few improvements I would like to make.  Here is some of what I hope to accomplish in a future update:

• Re-enter design in KiCad and try to move past the shame of the disgusting schematic I created in upverter.*
• Add voltage doubler to light green and blue LEDs from harvested power
• Add cap to an I/O pin to store harvested energy
• Migrate to NHS3152 to get analog for new features

* The tool had nothing to do with the quality of the schematic.  I have no one to blame for that but myself.  I am moving to KiCad because it is a much more capable tool and I have been burned by upverter updates in the past.  I promise the new schematic will be a vast improvement.
