I have tested my setup on the dev board that I used to program it and it worked.

What dev board did you use to program it?

Are the 4 328's you tried from a regular Arduino board, or did you just buy them as parts?  Maybe the chips don't have the Arduino bootloader / fuses set and instead is operating off the internal 1MHz oscillator?

I've had very good results from following the breadboard writeup at the following site:

http://www.imagearts.ryerson.ca/sdaniels/physcomp/tutorials/Arduino_standalone/ard_hack.html

Its always good to start with the basic blinking LED sketch too, just to make sure the breadboard setup works before getting too ambitious with additional components.

Liquidware made a RelaySquid thingie: http://www.liquidware.com/shop/show/RS/RelaySquid  sort of like a switching power strip.

I love how you managed to fit a bunch of components under the socket.  Great use of space!

This is a really well designed shield, and is dead simple to use.  A great addition to anyone bag of tricks!  Thanks so much for making it. smiley

That's pretty cool.  They even let your print off the PDF of the layout yourself if you already have parts.  Will have to try the layout tonight.

I agree with pluggy & gbulmer.  Add an extra row of holes on the board's digital side and leave them un-populated.  This would maintain shield compatibility, while giving people the flexibility to have 0.1" spaced connections possible without the bending hackery.  The only downside I can see is that some people might start manufacturing shields that use the newer spacing, breaking compatibility with older boards.

On the other hand, people can just go out and buy a seeeduino if they want standard spaced pins.  That's what's great about the ecosystem.  smiley

florinc : yes, there is a serial port, but the official SDK won't let you access it, so you'll have to use a jailbroken iPhone / iPod to use it.
With the latest 3.0 SDK, there's at least a better chance that we can use the dock connector:

Using the new External Accessory framework, your application can now communicate with "Made for iPod" hardware accessories attached to iPhone or iPod touch through either the 30-pin dock connector or wirelessly using Bluetooth.
http://developer.apple.com/iphone/program/sdk.html

Not sure exactly what the whole "Made for iPod" part is about, you might have to get one of Apple's special chips or something...

I don't see anything in the SDK on bluetooth or hardware interface. I think network/wifi is the only way to go (officially) right now.

The iPhone SDK has full support for a TCP/IP stack, so talking to an Arduino with an Ethernet shield should be possible.  If you're looking at physically hooking up the Arduino to the iPhone dock connector, I think you can talk to some of the pins... I don't have the SDK docs in front of me.  You would have to become a registered iPhone developer (and pony up $99) to do anything beyond a web based app, or go the jailbreak route.

Put simply:

Assuming .1 gateway:  Works for the majority
Requiring a gateway: Works for everyone
---------------------------------------
Assuming a subnet:  Works for the majority
Requiring a subnet:  Works for everyone

This suggests that somehow the current *option* to have a default subnet and gateway means that there is *no way* it will work for those who have a different situation.  There are multiple forms of the constructor, some which allow for defaults, and some that allow full configuration.

Now, if the argument is primarily about what is a 'right' thing to teach those who are just getting into networking, I think that's a valid discussion.

My personal feeling is that "Assuming a subnet:  Works for the majority" is a good definition of a default value.

The vast majority of networks I've encountered use x.1 as the router, so I think it's a decent 'guess'.  Most home routers that deal up DHCP addresses do this.  For networks like yours that are configured differently, there are options to provide the correct values.

The documentation on server: http://arduino.cc/en/Reference/ServerConstructor is more clear on this than the documentation on client: http://arduino.cc/en/Reference/ClientConstructor so the documentation should probably be updated to say what's going on with the abbreviated constructor.  The documentation for begin: or begin: http://arduino.cc/en/Reference/EthernetBegin states the optional and default values pretty clearly.  Not sure how to request documentation changes.

The "data-sheet" is a bit thin, but they do provide eagle files that has a full schematic of the board.  Its the "Source file" link at the bottom.

Has anyone used / looked at the Seeedstudio Relay Shield?

http://www.seeedstudio.com/depot/relay-shield-p-641.html

For $20 seems like a decent option, about the same price as the PowerSwitch, but it has 4 outputs instead of just the one.

Any chance of the wifi class subclassing Print?  Then we could use the print() and println() methods and not have to worry so much about string processing.  The standard Ethernet library does this.
