Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I was discussing microphones with one of my teachers yesterday. He mentioned that the FCC is limiting the available bandwidth for wireless mics. I thought why not use a basic stamp or pic as a network interface and create a network of microphones over WIFI. However, after some reading, I am thinking bluetooth may be better. We have a theater that uses several large diaphram mics and probably 7 or 8 wireless sets. The stage is probably 100-200 feet across and 50 feet deep. The booth is in the back of course. Here are the two systems I was thinking of.
Using an A/D converter with a microphone cartarge attached. A pic microcontroller would take the digital signal and convert it to a MIDI stream. Then, the MIDI stream would be broadcast over WIFI to a router on the side of the stage. From there, the signal would travel over a gigabyte network to a main computer in the back where a custom app would sort and mix the signals and feed them to the main amp. There could also be a web GUI on each mic to taylor it to the individual user.
multiple mics on the same channel
high bandwidth and speed
The other thought I had was some bluetooh mics. However, I don't know a lot about blutooth. There is where I really need opinions. I was there could be several USB recievers above the stage connected to a computer and have the computer create a MIDI stream that can run to a control computer in the booth.
The problem I run into.
With the WIFI, I know I can have several different streams that can be mixed in the back. Can I create a MIDI stream for each mic with bluetooth? Also, would I be able to tune the bluetooth mics? I know bluetooth will not have the range of WIFI. Do you think it will still work?
I just want some opinions one one vs the other. Thanks.
Thanks for the links. My idea was to get away from the conventional ones and try everything via WIFI. That way, everything would use the same channel. After talking with a few people, I have a design in mind.
