Could you move the post over to the proper forum please. (I don't have permssions to do that).

All things considered, a byte is 8 times smarter then a bit. If that were true, then a byte should only store numbers up to 8. Could it be that a byte is greater then the sum of it's parts?

Yes I've looked for monkey guts all over the web, but have found very little.

I did find that the microphone was probably used to turn off the external mic's when the chimp is howling.

I haven't figured out how to skin the monkey to get at the rest of the head. I've heard it's tricky, (which wasn't much help). I want to be able to re-skin it after I've had my fun.

He emailed me back, and sent some useful info. It looks like the easiest way is to just send singles through the connector at the bottom.

As he says:

Aibopet has kindly given me permission to post his finding that he sent to me via email.

 

Control Code Modulation

The RF radio control is modulated with a simple digital code to specify the different features.
For modulating the signals yourself, the signal looks something like this (timing values are approximate, but they work for me):

Each code is 11 data bits with a specific start and stop sequence. Signal from the radio is normally random noise. When driven from the PC, keep the signal low until needed (ie. the start bit will start with a low->high transition). Start bit: (assuming the signal has been low for some time), the signal goes high for 8.4ms. Data bits: for each of 11 data bits, an encoded signal is sent (total time per bit ~6.4ms) Sends the most significant data bit first If the data bit is 0: signal goes low for ~2.2ms, and high for 4.2ms If the data bit is 1: signal goes low for ~4.2ms, and high for ~2.2s Stop bit: When completed, signal goes low for at least 6.4ms.

The signal described above is the demodulated digital signal found on the pink wire described above.

Control Codes

Here are the code numbers (as used by the driver software).
There are 3 different types of control codes.
The first kind is a simple button press (eg: Demo), the second kind is on of the 6 skits (depends on mood).
For the first two modes, when you press a button, the code is usually sent 8 times by the RF transmitter (the remote) to make sure it gets through.

Simple Controls (same regardless of mood switches)



• $009 = DEMO button
  
• $00A = Program button
  
• $00B = Alive button

Undocumented/Internal

$006 = enter "chirp" mode (debug mode)

$00? = exit "chirp" mode

Skit buttons (influenced by current mood)

$000 + MOOD = "X" button

$001 + MOOD = "Y" button

$002 + MOOD = "Z" button

$003 + MOOD = "A" button

$004 + MOOD = "B" button

$005 + MOOD - "C" button

NOTE: MOOD = $000 (Curious) or $100 (Happy) or $200 (Fearful) or $300 (Feisty)

The last kind is the most complicated where two different joystick settings are sent in the same 11 bit code. Which joystick is sent depends on the mood settings (see the manual for how the mood switches influence the functions).
For the full range of motions, you need to send two different kinds of codes (eg: Mood $000 and Mood $300)
In the regular remote, the code is sent while the joystick is down (???IIRC).

• $400 + MOOD + RIGHT_DIRECTION*16 + LEFT_DIRECTION
  

MOOD is one of the values described above ($000, $100, $200 or $300).
RIGHT_DIRECTION is the position of the right joystick (value 0->8).
LEFT_DIRECTION is the position of the left joystick (value 0->8)>


The joystick positions (RIGHT_DIRECTION & LEFT_DIRECTION) are specified in 4 bits each:

• 0 = joystick in center position
  
• 1 = joystick up
  
• 2 = joystick down
  
• 3 = joystick left
  
• 4 = joystick right
  
• 5 = joystick up and left
  
• 6 = joystick up and right
  
• 7 = joystick down and left
  
• 8 = joystick down and right

OK, I've put the image up. (I had no problems seeing it).

Right now the monkey is lying disassembled on my bench under an irobot development system that has caught my attention. Too many toys, not enough time.

The code block was the first attempt at the image.  Your link just brought me back to this thread.  As the only other images I've uploaded are these I'll put them on again. (they are from your server so I don't know....) P.S. what forum software are you using, (just so I know what to stay away from).

Hey that's great. My monkey has be relegated to the top shelf to stare menacingly at people who come into my office. My goal for him was to have a speech synthesizer hooked up to him, with the mouth and random other movements to have
"conversations" with people. Never got that far, as soon as I realized that I couldn't easily control the motors and had to go through the wireless I lost interest. (In this project)

Perhaps though depending on your progress I may get back into it.
