Well, I have some doubts that it'll work on your telly, tr1p1ea, given the horrible inaccuracy of the timing and missing parts of the signal. :) Only one way to find out, unfortunately.

As always, be very careful about plugging some hacky calculator-related project into your expensive plasma TV... I've done all my development with a cheap VGA box and my old Game Gear. I can't promise you anything, and don't really want to be held responsible for any damage done. :|

So this is similar to how they display images/videos from a audio jack?

Who are "they"? :)

Audio equipment isn't usually much good for outputting video signals (too low bandwidth, not suitable for DC).

Well, PADs are starting to have a T.V. out through the jack..

Not sure this little pet project has much practical use, but all I can say is wow. It does look pretty freakin awesome. Is that a game gear with a tv tuner that you are running the signal to on the second pic???? That's pretty wild. I'd love to test this out but; 1.) I live in NTSC territory and 2.) I would have no idea what i'm doing.

Ah, 3.5mm stereo jacks are relatively common for A/V (one channel for mono audio, one for video). My digital still camera and Game Gear TV tuner both use this connector. I suspect the PDAs have dedicated hardware; video signals tend to rely on a sample rate in the megahertz range and DC voltages, audio hardware usually has a kilohertz sample rate and can't output DC properly.

Yes, that's a Game Gear with a TV tuner. :)
This might work on NTSC hardware, but the display will be cropped. It certainly works on the hardware I've tested on when the hardware is in NTSC mode. Colour encoding is different, but as no colour signals are generated that doesn't really matter anyway. :)

I sent a quick email to ticalc.org and they were kind enough to feature the achievement.

Congratulations Ben, top work!

Geez... Ticalc.org really is dead nowadays... Ten comments on this story, four on the previous... Back in our time it used to be HUNDREDS ;)

Heh... I was just looking back to the articles between 2000-2002 when i had just gotten into the TI calculators... some of the conversations i had! Ah it was so much fun then but i wonder how annoying it was to everyone else?

wow, when I saw this on ticalc, I was amazed. Again, you push out to the mainstream all sorts of ideas and projects that I never would have thought of doing. And you do it well! RS has the music, MC has the tv...only thing next is greyscale movies, playing sound while being displayed on a tv.

Great work Ben, you can put another notch in your belt! You are surely one of the greats that keep providing a fresh new look on how I and others percieve calc programming. Keep it up, I look forward to see what else you got coming!
