My first post mentioned that I ordered my boards from: http://www.oshpark.com/ It's been a while and since then the boards came in, have been populated and my layout is up and running. Manufacturing them and delivery took around 30 days but if you are in no rush then do recommend them. The quality is great for prototype boards. The drill hole alignment on the pads was well centered but the silkscreen was off a bit only on the backside. No worries there as long as the drill holes are good.

This was my first custom board so dropping the bootloader on was interesting. It turned out to be easier then what I was expecting. In my world, that never happens.

Very nice project. I've used the twitter example code you text me on a button press. Would come in handy as some type of alarm of I'm away. Getting it working on the new wifi shield would be nice but its pricey.

I'm working on just such a thing. Can you elaborate on what some of the Leonardo's quirks are?

Those tiny scopes are cool. Not sure if I would every use it but I love the idea and size of it. The OLED screen I have is 1" x 1.1"in size.

My coding skills are pretty bad so I just repackaged this project:

The OLED is from ebay and is crazy small.

It's a tiny OLED display with a 328, linear reg and two pushbuttons.

After a bit of digging I found a place for super cheap PCB manufacturing.

http://www.oshpark.com/

My design is 1" X 1.1" which cost $6 for three pcs + $5 shipping. I'm in no rush so $5 is the cheapest available.

Thats crazy cheap and my first order with them so I'll follow up once I get them back.

Mike

True. I stripped out all of the good stuff! This is just a starting point so it it works so far I may add the charger and booster on the next go.

Mike

I'm just finishing up my first custom Arduino board. Once the bootloader is on I plan on connecting the smaller mono OLED display found on ebay or the larger color 4DSystems type. It features a 1A LDO regulator and two pushbuttons. Not much else since it's onlt 1.1" X 1.0" in size. Feel free to let me know if I missed something on the schematic. I tried to figure out what pins go where from the official arduino board schematics. Either OLED will push onto the front and the GPS will have to be sticky taped to the rear. On top of the regulator. The idea and code I used is at: http://karman.cc/blog/archives/746

Excellent library! A big thank you from me and I cant wait for any updates or examples coming in the future.

Mike

Sorry about that. Just changed the video to public.

I also have a video of it in action:

Thought I would show off my Arduino Ethernt Shield mounted comfortably in a Hammond Enclosure. If anyone is interested then I can do some searching for the exact model number of the box. I have the shield mounted on an UNO but there appears to be enough room for it to be mounted onto a Mega. The end caps are aluminum and had the USB and ethernet spots drilled out and filed by hand.

Each twitter post is set up to text my cell phone so I use it now as a remote monitor with the ability to turn on and off I/O pins with my cell. No one cares to read these twitter posts but me. It could be connected to a motion sensor with the ability to turn on an alarm, monitor the temperature of something with the ability to remotely shut it down if it gets too hot. Many possibilities...

I have two way communication working on my Arduino with ethernet shield. Right now with each button press it tweets that a button has been press x many times, turn on LED? If a tweet a Yes the LED turns on and a No turns it off. If a Yes does not work then two duplicate posts in a row will not work.  A time stamp or random number after each Yes or No is possible but ugly. Is there another way?
I found the bit of code below that I am NOT currently using because i'm not sure what it does or if it is a possible fix for my problem. No idea what the "status == 200)" does.
 

if (twitter.post(buffer)) {
    int status = twitter.wait();
    if (status == 200) {
      Serial.println("OK.");
    } else {
      Serial.print("failed : code ");
      Serial.println(status);
    }
  } else {
    Serial.println("connection failed.");
  }
