Serial to NTSC 33

Just need a WM dock APP to recieve caller id now."
Interesting toy. Especially dig the BASIC example code.

mp3 display is a good idea (Score:1)
much nicer than dealing w/ a lcd display, plus all you need to have exposed now is the ir receiver! (nicer 'cause you don't need to make it look nice anymore)
the way i see it making an mp3 player just got much easier, no need for a nice box (since you can hide a deskop/minitower case behind your stereo rack)

It's quite a simple unit to build but why do it if you can buy it off the shelf?
Here's how I would do it. I figure that you could achieve the same effect by using a Philips I2C teletext chip (I think the new ones have onboard framebuffer ram - 8k don't get excited) and they can handle incoming video to overlay on. The small 8 pin chip on the module looks like one of the natty 8 pin PICs to do the RS-232 to I2C bit bashing which should be dead easy to program. The rest of the components should be straight off the standard Philips app note as I remember.
A bit of smart programming would allow you to build something that could suck Teletext info off onto a serial line....although I think that Linux do that already with a parallel port and a few gates.

In need of Ethernet (Score:1)
What I'd really like to have for my custom-built electronics projects is a simple two-way Ethernet to RS232 board of some sort. Currently I'm using a printer server to drive remote displays (my favourite is a big, bright vacuum flourescent display from IEE), but it would be nice to have something smaller and 2-way.
If such a module existed, it would be trivial to simply run Ethernet cable alongside audio cable, and have your "stereo rack MP3 player" be nothing more than a small terminal that controls an MP3 codec somewhere else in the house.
CallerID->Video (Score:1)
Seems to me that both these units should be combined into one unit. It would be neat to have caller ID data overlayed right on your TV screen. No need to look over to some dumb little LCD screen on some box somewhere. Since many folks already have a phone line run near the TV for DSS access, it seems natural.
Aside from that, the only use I can think of for this little beast would be video editing since it can overlay the text. But for not much more money ($200-300) you can buy a "real" box that would do a much better job. Or spend a little more and get a real solution.
Oh, I suppose when coupled with one of those video transmitters and a CCD camera you could build a robot that could broadcast the video as well as text messages back to a TV in the room. That might be cool...

For instance, one can merely trap the data coming into the serial port. The specs (of the caller id data stream) for doing so are freely available, and there is no need for a dongle hanging off the back of your machine.
Perhaps I do just lack imagination.
