Nice list. (It’s also nice to make #3.)

Exciting to see our WiiFit Arduino powered Robotic Labyrinth come in at #14. Its been two weeks since the YouTube video hit it big.
We’re going bigger too with our Science City Robotic Labyrinth project going to 12 foot long. You can check it out on:

How can the Arduinome not be on this list?
February 2nd, 2009
The Arduinome is pretty similar to #3.

Load your Diecimila with Simple Message System from the archives at arduino.cc and use my linux shell script package to make a general-purpose controller. Easy to write your own shellscripts for any project. Maximum flexibility. Get the tar package from http://user.cavenet.com/rolandl, called SMS1.tgz. Full IO & PWM control. AD is scaled to mV and formatted for import to most spreadsheets. GUI via xdialog. I am using reed relays connected directly to the IO pins: elexp.com #22RD5, a buck and change each.

I have a few Arduino projects I have been working on that I would like to share. I have a really popular PHP Serial project I have been working on that is pretty cool. I have a special area on my blog just for Arduino projects. Here is the link http://missionduke.com/arduino-projects/

What are the typical/most interesting use cases involving Arduino?…
This is a bit hard to reply to. The Arduino is a microcontroller similar to whatr you find in almost every device. So it’s a bit like asking hat you can do with software and the answer is “everything”. There are however lists of most interesting use…

What are some cool things one might make with the Arduino board?…
The Arduino is a small, cheap, microcontroller platform that’s easy to get started with. Artists and people with ideas, who may not know a lot about electronics can get good results fairly quickly. What you might make depends upon your imagination.

Check out http://daisyworks.com – we have an Arduino-derivative (ATMEGA328 w/Arduino Bootloader). It comes packed with custom case, Bluetooth, IrDa, SD Card, Servo ports, and we pull all the other pins out to standard RJ telco jacks so you can have plug-n-play sensors.
We wrote software for the Android & Mac, Linux, Windows so you can do Firmware Over The Air (FOTA) to the device using Bluetooth. You can also browse an App Store and pull down pre-made applications (firmware + user interface) – deploy it to the device and start interacting with it, one-click.
