Pranam Tries To Make Things

So, in respect to the fact that the final project is coming up, I decided to get started on the final circuit. Recall that my final project is a continuous cell culture monitor that will shine an LED through a cell culture tube and be received by a photoresistor, which I made for input week. So, this week, since I have to leave early for Thanksgiving, I wanted to quickly make an LED board, and spend the rest of the week (probably after Wednesday's class), improving my Eagle design skills to make the overall circuit.

I pretty much used the RBG demo board as my starting point for the week, and will use it to help me design the final circuit, especially the input LED

I quickly milled and stuffed the board. It was so small that putting all of the pieces in was very difficult! I also liked utilizing the integrated circuits, which are insanely tiny -- pretty amazing how much electronics has advanced to allow that to happen.

Finally, I just connected the board to power (5 V) and the programmer, so that I could program the LED to light up at will. It worked, but will require some more iterations.

Now, onto the design, which I accomplished during the Final Project, where I designed a simple LED board to integrate within the FabSpec.
