Bluetooth Watch. Options

if it can use palmorb then i am intrested, bluetooth would be a killer app for this thing as then i could hook it into my sysetm and see if i can make my Z pull the phone number from the phone and disploy on the watch then route the audio to my bluetooth headset smile.gif, all we need is a serial port i guess wink.gif

now where can i ind one of these in Australia?

Hmmm. . . Dismantled mine today, just to prod, and discovered something. The IRDA chip (2mmx10mmx2mm) has 8 pins on the back, and a larger pin holding it down. So looks like you could steal a serial port from the IRDA. However, you have a total of 1cmx0.5cmx0.2cm space internally to fit a bluetooth module, although you could hang it of the hole (full of translucent plastic) for the IRDA beam, which is about 2mmx12mm square.

Don't know if that link's any good?

Even just as it is, it's a cool, and useful device. (Just a shame about the 1 to 2 day battery life. Ah hell, who cares, you can charge it from a USB port!)

APU = Audio Processing Unit - Another name for a sound chip.

If we don't need it for ADC, that's great. XD

I thought the 21S was better because it has a dedicated camera input, which would save us alot of hassle in linking up the camera. . . After all, the three main functions I see for this are to read SMS messages on the fly, instead of having to frell around with getting the PDA out, To announce incoming calls and allow you to answer them over bluetooth headset (And possibly to call numbers, using an onscreen dialler. . . CallerID is also I think feasible, by scrolling down through an addressbook), and in the case of Videophone calls. . on the wristwatch, and for that reason exactly, to be a more practical videophone.

In terms of SDRAM and FLASH, I was thinking the same as I am for the PPZ phone ROM,

Something along the lines of the Top left chip on that image of the Universal. . a 32MB NAND and 32MB SDRAM combined chip. The camera, because of my main use for this, is one of the things I'm least willing to drop, although I'm happy to sacrifice alot of quality to go for a lower power-consuming Camera, after all. . . The bluetooth connection will only allow about 160x160 monocolour each way anyway. . .

I was also planning on having this thing keep the TFT active, although not the backlight, and like the Fossil Abacus. . call a program once a minute to update the screen with the new time. After all, it IS a watch.

The iMX versus iMX21S

There's a comparison table for this, and only the 150mhz iMXL has the camera interface, and the iMX21S is the lowest power device to have the Keypad, the dedicated SD, NAND support, and the Smart Speed switch to save power.

I'm getting a suspicious feeling you want me to dismantle my watch again. . . .
