The USB2Serial Dongle seems to have rather a large amount of components on it  (for me that is).

 

I was reading up on the usb-serial chip, and it mentions that the new ones have a built in eprom and OSC.

 

Would that eliminate some of the bits off this design?

 

Im guessing the eprom is used to store the USB Product ID ?  -  if so how is that bit programmed.

 

 

I tell you what i want to do...

 

I have been looking at all the new USB toys that were about at xmas and ive seen the following...

A hampster wheel that revolves at the speed you type (including a fluffy hampster).  it retails @ $30ish.  (sorry im in uk so im guessing it actualy was £15).  which is amazing considering the fluffy toy + wheel + usb cable + electronics + software disk + packaging + retailers profit is in that low price.

 

So if i were to make somthing like that it would cost too much, even if i was to purchase these units in the 1000's   not that i want to do any thing commercial at this stage.

 

I think i will get one of these anyway as i think this would make a good test tool as a known worker!   As i am most impresed with the quality of all the other products parallax has sold me.

 

But if there is a simpler design template that could be used on every project.

 

Many thanks...
