There are heaps of them on YouTube, but i'll see what i can do once i get the domino and usbizi chip inI'd love to see a tutorial on surface mount soldering...
Failing that, i can just put some FT232RL's on boards, they have the same pin pitch.

Hari, with 100 pins there is no way you'd get that in anything other than LQFP/TFBGA/LQFN packages. Those IC's are really easy to hand solder once you know a few tricks. I have a FEZ Domino on it's way to me with a dead NXP ARM7 on it, and a replacement ARM chip, i might have to do a tutorial on how to solder it.
0603's and above are easy with a pair of surface mount tweasers. If you're really worried about the board, get one made at PCBCart.com, then head over to SMTStencil.com and get a stencil made. Buy some solder paste, stencil on the solder paste, place your parts with surface mount (self closing) tweasers and then heat with a hot air gun slowly until the solder goes all liquid.
Surface mount isn't something to be afraid of, i only first got PTH parts after getting a FEZ Domino and a Sparkfun Inventors Kit... I've been doing surface mount only boards for 4 years - it's what i learnt on.

You might want to take a look at the new Netduino Plus which has ethernet support. Other than that, just use a serial port, or a TTL to USB Serial Port cable to talk to your PC. With a USB serial port you can just write stuff out on the netduino to the serial port and read it in on your pc. Both NetMF and .Net Full have the SerialPort class and the code is the same between them.

It's using GHI's EM module on the back, so i wouldn't be surprised. Is it just me, or did just about everything he tried to show working... not?

Very nice! Writing code for one of these was about 3rd on my todo list, so i guess i dont need to worry about that any more! Thanks!

Ok well i'll look at it this week, it shouldnt take more than a few hours if i have all the footprints and it decides to route nicely.

I've seen a couple of threads about the board and schematic files and people wanting them in Eagle, is anyone interested? I'll port them over if there is enough interest - i have an Eagle Pro license so the 4 layer restriction is no problem to me.
I have a feeling i'd have to do a redraw from scratch, so the routing will be different however components should mostly be in the same place (all the important stuff anyway) - it would be enough for using to generate your own netduino based devices in any case.

I have drivers for the FEZ to run all the sharp distance sensors accurate to within a few mm, if anyone's interested i can port them over to Netduino, however i don't have one to test on (yet).

also, consider digikey.com(i prefer over mouser 90% of the time) and farnell.com- farnell is great for international people without access to a decent electronics store. In most countries it's free overnight delivery - however they can be considerably more expensive.
Be wary of dealextreme, some of their stuff is absolute rubbish (get what you pay for).

Wikipedia can be a really great resource for understanding what different protocols mean, usually the articles are high level enough that most people with basic electronics knowledge can understand them and if you need more information you'd be able to go to google to look for specifics.
1 wire is just a protocol for systems to communicate, like i2c, CAN, SPI, TTL and RS232 among others are.

Unfortunately, Netduino doesn't appear to support 1 Wire, so you'd want to look for an i2c, spi or analogue output temperature sensor.
Something like a LM60 from National or a TMP36 from Analog are examples of analogue output sensors.

klotz,
A bit of both. But mostly a software limitation. If there's interest, we can start a community project to expand this to 4GB or beyond (for MicroSD cards that support SPI).
Chris
Any chance of going native on the uSD rather than using SPI so as to get the higher speed read/write?

Set your analogue input voltage scale as 0, 3300. This will then read out mV rather than the raw ADC value. I don't have the SDK installed on this PC so i can't give you the exact code, however when i was looking through the netduino libraries earlier it was there.
If you're getting about 70mv, this is about right for a device that isn't hooked up correctly, check your ground, make sure the maxbotix is powered, and make sure you have the avref connected as above.

We're working on it, slowly.
After this we're building SKYNET. ;-)
Ah good idea Greg, don't tell them we've finished it. Just let them think we're still working on it.
btw, i'm Issus on codeplex.

At the moment we only have GLL and RMC packets implemented and no way to change the baud rate or update rate on the devices yet. There is still a lot to be done and it would be good to get some more experienced developers on the team.
