Re: PCB fabrication
Felis,
Please contact us at team(at)tom-ic.com! We'll find an agreement for sure :-)
At Tom-IC you get one free copy on any PCB order (any surface & any number of layers) placed before end of february 2008.
For your PCB prototypes, try...
Re: final year project
Hi,
Wireless is a nice way to learn a lot. RF is very multi-disciplinary. Have a look at nordic chip nRF24L01. it has got a SPI interface -> easy to play with and it'll certainly trigger some ideas :-)
We have a good price for it **broken link removed**
At Tom-IC you...
eagle pcb power tools
Hi,
You can use Eagle power tools. Very nice piece of software that integrates to Eagle and let you do just what you want. Have a look at **broken link removed**

Re: What are PCB manufacturing files???
Hello,
You need to supply the gerber files that contains the layout for each layer. Also the drill file definitions are of importance. If you want silkscreen, you also need to supply gerbers. It all depends on the type of work you want the PCB supplier...

Hi there,
I think you could do some temperature telemetry based on the nordic chip. It operates in the ISM band of 2.4-2.5 GHz and is a piece of cake to program through its SPI interface.
Basically you need the nordic chip, a microcontroller unit, a T° sensor, e.g. from Dallas and some...
I wish you the best in your project! I can help with some cool services :D
We're already working successfully with many engineering schools, robots clubs, etc.
For your PCB prototypes, try http://www.tom-ic.com/index.php?cPath=22.
For your components hunting, just try our BOM service **broken...
Well, sure you can use a BT module but it won't serve your need better in term of price, power consumption and footrpint complexity.
The nRF24L01 chip is really a piece of cake to program through the SPI interface and programming a PIC in C is not that a big issue.
Maybe you could be more...
Hi,
For your RF link, you could use the nRF24L01 chipset from Nordic. Easy to integrate with a low cost MCU. Check http://www.tom-ic.com/index.php?cPath=38 for a 5 pieces bundle. The MCU should be featured enough to interface a temp sensor, e.g. from Dallas.
For your PCB prototypes, try...
Hi,
For the RF architecture, I'd propose you to go with the nRF24L01 TRANSCEIVER from Nordic VLSI. Easy to integrate with a low cost MCU that you can also use with a level shifter for your RS232 interfacing. Then the programming with VB.NET shouldn't be an issue.
For your PCB prototypes, try...
Usually, the basic way to do it is for 2 layers:
1. put a thin layer of photoresist on your board and let it dry
2. insulate the 2 sides with your top and bottom films (can be laser printed transparent slide)
3. use of chemicals to reveal your board
4. use of chemicals to etch your borad where...
Looking for Nordic or Chipcon ICs?
From my experience, nRF24L01 is verz versatile with its multiceiver approach. It also integrates a complete protocol layer that reduces the MCU footprint.
Let me know if you need any components or PCB services. **broken link removed**

how about coding in C using www.bknd.com CC5X free version? It should be sufficient for what you interested in.

Totally agree with the light emission related to the gas choice.
We're very probably dealing with multi-color diodes.
BTW you can find many of those on http://www.tom-ic.com/index.php?cPath=27
If you'd like multi-color LEDs, it's no problem. Just use our BOM service **broken link removed**...
detect fiber cut
Maybe you could look at TDR or Time Domain Reflectometry. That's what is used to detect cuts along transmission lines.
Hope this helps.
