- LED Visor, MSP430 (Final Build into Visor)
First off, I decided I wanted to put some LEDs on a hat or visor. This made for a nice, trivial project.
I had a ez430-F2013 which I'd picked up from work . It wasn't quite what we needed at work, however it was just fine for a small home project. If your interested, you can pick one up from digikey for about $20.

- One was a PCB EDA tool, KiCad. While I know that a lot of folks like Eagle, I wanted something that was open source. After looking at gEDA, I decided I would rater use something a little more integrated.
- I wanted to try out BatchPCB, a service which fabricates custom circuit boards. While the wait times can be long, the price was right. I wanted to see if I could take a circuit idea from schematic capture, to layout, to reality.
- Provide a power source (e.g. power regulation)
- Provide a circuit for driving the LEDs.
- Provide a way to connect up the ez430 development board.
- Provide a way to control the LEDs.
The TI MSP430F2013 can run from 1.8V to 3.6V. For this project, I decided I wanted a 3.5V regulator. After some looking, I picked a small 3.5V 600mA regulator.
I drew up a circuit by hand in my lab notebook, using the reference information in the datasheets for parts I'd selected.
