If you could have a shield for the Arduino that added any function, what would it be?

Inthebitz, you guys have a great store. I ordered my 2nd Arduino from you, and I also order the White ExtenderShield, Solder Starter Kit, and Lithium Backpack. Backpack hasn't shipped yet, and I understand, you guys were out of stock. I would have ordered the TouchShield Slide, but I just don't have that kind of money ($170+). Why are those things so expensive, anyways?

I use arduinonto make neat projects that need physical computing. I got my Duemilanove for Christmas and have since purchased two xbee's, another arduino, an RFID reader, and several accesories. I've also made my own shield. Before, I had only done a bit of c++, and I knew about mostly everything in mainstream technology. And I'm only thirteen. I working on a project right now that uses xbee, RFID, and two arduino's to wirelessly open doors.

I say "saw-der" when saying "soldering iron" but I say "sold-er" when saying "solder". I was raised in the south, so I say it like "saw-der" more often, though.

Thanks for the info. I'm ordering up some ATtiny2313's and I think I might try to get all of the files ported.

Someone made a post a while back (around spring break, IIRC) about how to port the arduino core and language to different AVR chips. The guys kept citing the Teensy and how he ported it, so I guess it was the creator of the Teensy/Teensy++.

Anyways, what I'm getting at is, does anyone have info on porting the Arduino language to other AVR micros (i.e., the ATtiny2313)?

AlphaBeta, this thread was a good idea. Great job!

Personally, I think that all of the spammers like KevinDuino need to be banned. Not just accounted banned, IP banned.

But macegr's idea about an Arduino specific Captcha is a really great idea. It needs to be something tough, though... like, "How many pins did pre-Diecimilla (sp?) boards have?", or, "What's the recommended serial voltage for an XBee?"

Hey all, I started a blog about my exploits and adventures in the Open Source world.

Head over to http://www.braindrink.wordpress.com if you want to check it out. I should be posting updates every few days (5-6 depending). If you have any suggestions, post 'em or leave 'em in a comment on the blog.

Enjoy your brain drink!

I got my reader! It's so tiny... and sleek... and black.. and awesome.

Has anyone done any projects with an ID-12 or ID-20 RFID reader?

My 2nd Arduino, an ExtenderShield, an Innovations ID-12 RFID Reader, a custom shield, a Lithium Backpack, and two Xbee breakout boards are making their way to my house from Liquidware and Sparkfun. I already got my two teeny-tiny Xbee's, and they look so awesome. I also have to go get a soldering iron from the 'Shack (radio, that is), and some servos from a local hobby shop.

ARDUINO IS AWESOME.
