Website Bug

Hello,

Hopefully this is the correct place to report this.

From this page:

http://letsmakerobots.com/rss_feeds

There are a number of RSS feeds listed: "The front page", "Robot projects", "Tips/walkthroughs", "Forum topics", and "Blogs".

The page that the first one -- "The front page" -- links to works. (I.e., it send you to an RSS feed.) None of the rest of them -- none of the other 4 -- work though. The remaining 4 all send you to an HTML page.

RS232 versus TTL, for cameras?

I've been noticing that some of those barebones miniature cameras suitable for usage for robotic vision come in two flavors. One flavor supports RS232, and the other flavor supports TTL.

I know what RS232 is, but what is TTL?

Is it this? http://en.wikipedia.org/wiki/Transistor-transistor_logic

I'm (or at least, used to be) familiar with working with RS232. Does anyone have any pointer to working with TTL?

 

Camera Recommendations?

Hello all,

First time posting.  (Searched the site for an answer to this question, but couldn't find one.)

I'm looking for recommendations on miniature color cameras that can be used for a robot eyes. I'm leaning on the higher refresh rate and higher resolution side. (It's OK if they're not dirt cheap.)

Does anyone have any recommendations?
