Dual Frequency RC Oscillator

This is what I consider my first real post.  This particular circuit allowed me to explore RC oscillators as external timers for micro-controllers.  If you want to see where I got the idea from, just go to the microchip homepage, and search their website for "Tips 'n Tricks'.  This was tip #1, and it had the same title that I titled this post.  I think I did a half-way decent job discussing this, between the video, code, and dry-erase board picture.  If you have any questions, feel free to ask!

So I found a 4-channel, 100 MHz oscilloscope for 150 dollars that is in working order.  I think I may need to get it calibrated, but otherwise, I can't find anything wrong with it.  I also found a variable power supply supply for 50 dollars that only needed a little soldering to fix up!  So now I have rearranged my desk, and turned it into a permanent work station.

Introduction

Hey guys,

The whole purpose of this blog is to allow me to show some of the projects that I have worked on (or am currently working on). 

At this point, the blog is likely going to focus on some of the embedded projects I have worked on / completed.  I started working with embedded systems in late November / early December of 2011, and have come a long way since then.  The only microcontrollers that I have used are those made by Microchip, but at some point I am planning on branching out.

I hope you enjoy what I have done here, and if you have any questions, I would love to help!

Regards,
George Burrows
