I used this:

To PWM EL-wire.  Very cool!
Except sometimes the frequency of the PWM interferes with the AC and causes it to flash badly.
I mean it looks bad.  So I skip some of the PWM values and choose which ones look the smoothest.
It looks like a Lava lamp, just as you want.
It is much easier to do this with LED's, because you wouldn't have this interference problem.

I'm sending AT commands to a RAZR with a USB Host Shield.  Google Circuitsathome RAZR.

Found a bad solder joint which sometimes works, especially when you press on it to test it!
The TX pin...

It's all good now!  Thanks everyone!

Sounds cool I want one when you're finished ;-)

I don't know much about HUD displays, but I've been working with GPS for 15 years if you have any questions about interfacing with Arduino.  My background is automotive manufacturing, I helped design the EEC-IV process.  A long time ago I wrote code to calculate acceleration and lean angle.  My senior project was a physics simulator.  And of course I love Motorcycles of all types...

The serial camera works with Uno, but I am still developing the PTP image object code from Canon.  I got my RAZR on Ebay, but I needed Verizon because of the locations I plan to use it.  There is no T-Mobile coverage.  What keys are pressed?  I'm asking because I will have access to a GSM RAZR.  Did you find an AT command for each key?  Like the shutter button?

My project is somehow related, but I am not using the RAZR. 
I am using this camera mounted together with my Canon:

Sending the image data with XBee.  Controlling a motorized panning head.  USB host to control Canon DSLR.
With a zoom lens I can zoom in to any part of the Lores image remotely.
Next step send the image object from the camera.
But it's really cool without that functionality!

When I call my sndstr function that is when it occurs.  You can send any AT command or any string.  Do not put this function call in a loop() which gets called 100x (acm_terminal sketch) unless that's what you want.  The particular AT command in my example is the first command I must send to my Verizon phone to initialize it to accept AT commands.  It is specific to Verizon not GSM.  You will not need to send it.  The sndstr function is defined before I call it. 

I understand what you are planning to do.  What specific sequence of keystrokes take a picture and send it?  Unfortunately I don't think the CKPD command is supported by my Verizon RAZR.  Will try it.  I hope it works with yours!  Have you tested it in terminal mode?  I recommend you try that first.  Knowing that it is possible to automate later with my code.

I have no regrets using my Uno to burn the bootloader.
Because it worked!
Took 2 minutes including soldering!
The instructions were simple, there was no confusion.
This is what an ISP programmer does?

Should uploading a Sketch be even simpler?

Is it possible to change fuses with 2 Uno's?

But wait.  Shouldn't it be easy?  It's only 5 pins.  No soldering.  It's easy to remove the whole Uno board from a project.  I don't want to burn the new chip bootloader, it's already done using Uno.  It couldn't have been simpler. 

I just want to upload a sketch.  You're saying using a Uno is inappropriate?  Too complicated? 

Well you're right it doesn't work.  But neither does my Sparkfun Xbee dongle.  Would that be a better solution for me?  Why doesn't that work?

You're saying I need to try 3 completely different pieces of hardware to be successful?  I think the problem is my PCB soldering.  Or am I forgetting something totally obvious?

You win a prize! 
It took me nearly an hour to figure that out.
I bet you got it immediately...

The IDE says "Problem uploading to board".
I would expect the L,TX,RX to act the same with both chips when uploading?
What is the L LED?  I don't know, just that it blinks with original chip installed.
Reading... Ah I understand it should not blink. But TX should?

Serial.println does not go to the phone.  I've been doing something similar, let me find the code...

Code:

uint8_t sndstr(char *s) {
uint8_t i,j,k;
for(i=0;s[i]!=0;i++) {
  k=s[i];
  j=Acm.SndData(1,&k); //could do all at once?
  if(j) return j;
}
i=13;
j=Acm.SndData(1,&i);
return j;
}

//later on...
 sndstr("AT+MODE=2");

I have the Verizon RAZR.  
There are many differences that were difficult to overcome, but now it's working!

Which AT commands do you use to send a picture?  I'm interested!

I am also curious about this. 
Is it possible to wake the XBee without resetting Uno?
Your link says the 120 ohm resistor is not possible for Uno...

Do you have an Arduino board to use instead?
