Creating a simple VEDR: Video Event Data Recorder

DirkK

Greetings,
Does anybody know of any resources that would guide me in using Parallax products to create a simple Video Event Data Recorder?·
In other words, I'd like to be able to write a video stream to RAM and, using a manual trigger or event, save the last [noparse][[/noparse]x] seconds to flash.· Yes, you may recognize this as the description for a 'black box'.·
For example: if a robot is wandering around and an event occurs, I'd like to be able to view the video stream just prior to the event.· I could simply record everything to flash, but that would require too much flash and the constant writing would shorten·the flash·life relatively quickly.

From the reading I've done so far, it looks like I might need additional chips to handle the encoding of the video stream.
Suggestions?

- Dirk

The Stamp products are way too slow and limited in memory to do anything along these lines.
The Propeller might be able to do this, but with a lot of external circuitry, mostly for adding memory.
The SX also might be able to do this with a lot of external memory.

Although this is a reasonable question to ask in the Stamp and Propeller forums, it's a general rule
that you don't post the same question in multiple forums at the same time. In the future, ask similar
questions in one forum at a time and see what sort of suggestions you get before asking again in a
second forum. You will probably find that you get what you need with a single posting.
