Re: Trakbox



David,

I believe your goals are a bit ambitious.  If memory serves me correctly the
Trackbox had something like a $400 price tag (1996 Dollars) for the kit
without and enclosure.  I wanted one really bad, but my wife said we didn't
have the money.  You can read all about it at:

http://www.tapr.org/tapr/html/Ftrakbox.html

Using new parts a FODTrack box will run you about $50 and all of the smarts
are in the computer in that design.

On the other hand, I bet you can do better than 5W.

73 and Good Luck!
Joe

P.S. I really don't need another project, but might be willing to get sucked
into something as fun as this!
