<DD><H4>The running light uses pulse width modulation to generate 16 levels of brightness. Fadeout length, movement speed and overall speed are user definable. <A HREF="kitt.s">source code</A><BR>
<BR>At one time, during debugging, I forgot to switch off the board while removing a wire and the FPGA was damaged. I removed the FPGA from the board and cut out the FPGA region from a fresh board. The new FPGA was then connected using post connectors. I am very grateful that I was granted to use another board.<BR>
<BR>I participated in the weekly meetings of the Urasenke Tea Ceremony Club. <A HREF="uracampus.html">Pictures from the campus festival</A><BR>
<BR>I was also able to take part in the seminar on Digital Signal Processing by Prof. Takahashi. <A HREF="seminar.html">Picture</A>
