The New $15 Picaxe Talking Skull Controller

[halstaff]

I'm converting but mine are 1.25 inches or 31.75 mm wide by 2 inches or 50.8 mm long not including the pins.

I didn't completely digest your reply at the beginning. Let me make sure I understand how it works in broad terms:

Your board has two modes: one for programming the PICAXE, the other for operation after you've programmed the PICAXE. The jumper on the board needs to change position depending on whether you are programming the PICAXE or not.

In the latter mode, the PIR input is used to take the PICAXE program out of the 'idle' state. It sends a command to the Tenda board to make it start playing a tune. This tune has one channel (the right one?) dedicated to the song that the user hears, and uses the other as a 'cue' channel going back to the PICAXE through the op-amp circuitry. When the PICAXE detects the cue on its pin 6 it will perform some action, such as using the servo output to make the jaw wiggle. After some time the PICAXE program goes back to the idle mode, waiting for the next trigger from the PIR connector.

Is this fairly close?

Thanks.

[halstaff]

Correct except I have my tone on the right channel and the left channel goes to the computer speakers.

[pshort]

Thanks.

Pshort has come through again and put together a schematic with the current modifications. My thanks to him for continually updating the schematic when I decide to make improvements. His work is greatly appreciated.

The mp3 player from mdfly just arrived in the mail, surprisingly quick. Now to start playing with it... I just wish that the pins were at right angles to the board rather than parallel to it.

Yes it's a bit of a pain but Sparkfun sell right angle headers:

Just FYI I will be ordering this module soon:

Seems to be simpler than the one MDFLY with ONLY serial control (no button control) and better positioning of the SD card.

[pshort]

Yes! I've got sound from the module!

Have to play with getting the volume to work now...

[pshort]

Got it working now. I had the bit order reversed in my software uart routine, I don't know how I could even play one clip with that mistake.
