Senior Project
I thought that perhaps people might be interested to know what I’m up to in school. At the moment, I’m focusing on finishing up my senior project, which is a low-power digital data logger. Today, I’m working on the PCB (Printed Circuit Board) layout for the hardware (click on the image to see a larger view of the current layout).
You can click on this other image to see a circuit schematic. The whole thing is powered by a Microchip PIC18LF4520 microcontroller clocked at 1 MHz.
Basically, the idea is to use a high-precision A/D (analog to digital) converter to collect data, and then store that data to an SD flash memory card in a Windows-readable format.
I have the SD card software written (that was by far the hardest part of the project). Now I just need to do some more extensive testing to make sure there are no bugs in that code, and then write the A/D software.

Wow, again!
So, in the end, what will this all do? What’s its purpose (besides getting you that A ) ?

Thanks Nathan! Haha, yeah, uhh… good question.
The “customer” that I’m building it for does lots of environmental research, so I’m assuming that he’s interested in monitoring analog signals from weather equipment (rain gauges, etc.). Pretty thrilling, huh?!?

That sounds awesome! I can’t wait till I get done with all of this Physics and such and get to do some actual circuit design…
