Eagle says 11 airwires... I can't find them

I've just "finished" a fairly complicated PCB and when i run the ratsnest, eagle counts 11 airwires. I've scoured the board and I can't find them. Any way to make eagle actually tell me which nets or show me the airwires?

Venus 634FLPx, chip antenna, and an amplifier

In an effort to get better performance out of a chip antenna (http://www.sparkfun.com/commerce/produc ... ts_id=9131) with the Venus 634FLPx, I'm planning to use the SMA661AS GPS amplifier. Would this actually increase the performance of the antenna? Are there any issues with doing this?

I don't think it's as simple as that, you need to speak to your service provider. Leon I figured as much. Unfortunately, this is for a system going into place in Rwanda, and I have absolutely no idea who the provider is. You can use the "AT+CREG" command to the the Location Area Code (LAC) and Cell...

Is there an AT command for that? Probably just getting the tower it's talking to would be great

Get location via GSM

Is there a way to get a GSM/GPRS (not GPS) module report its position geographically? Some cell phones can do this and what I'm wondering is how...

thanks :)

i ended up getting it at janus-rc. They gave me a discounted price since it's a slightly older firmware version

Where to find the GM862?

Sparkfun's been sold out for weeks. Where else can you get the Telit GM862? Or Telit modules in general?

Unfortunately cost is a big issue here and the $30 saved by using the SM5100B over the GM862 is important.

Any ideas about the charge interface or the reset pin?

SM5100B wiring

I'm working with the SM5100B GSM/GPRS module and I have some questions. The datasheet is pretty awful: http://www.sparkfun.com/datasheets/Cellular%20Modules/CEL-09533-User%27s%20Manual.pdf Page 24: How would I wire the battery charging interface? What's shown on the datasheet doesn't make any sense ...

Good advice. That's how I do it

You'll learn more about analog with the first one than the second. Analog is useful, but only as far as it'll get you. I'm a EE student also, and learning microcontrollers was the best electronics decision i ever made. My school has a class called "Computers as components." If yours has one similar,...

BatchPCB is pretty inexpensive - that how I do one-offs. BatchPCB is how i do it too. Painless and pretty fast. Limited to 8mil space/trace but I've never had a problem with that. Smallest drill available is 20mil, unfortunately, which is annoying but usually workable. You can etch your own boards ...
