Hello forum members and friends,

I created a machine to cut 4'x8' styrofoam boards, using PC interface,
stepper motors control by Allegro chips, XY movement and so on, all
controlled by a microcontroller via serial communication.  To cut the
Styrofoam it uses a Ni-Cr wire, AWG 30 (0.01") that has 6.5 (or 6.75)
Ohms/ft, requiring from 1.4 to 1.6 Amperes to generate the correct
heat.  4 to 6 inches of this wire can be powered by a common wall wart
6Vdc/1.5A.
I found this wire is some places around in US, but there was always a
high cost per foot, so I was forced to buy a big reel. Each machine use
only few feet of them, it will take a "million" machines to consume the
reel, so I decided to offer part of the reel by foot to the forum
members.

20 feet (6 meters) is only $12 (USA), $13 (Overseas), packing and
shipping included (regular mail envelope).  If you are interested email
me for further details, (I also have a small quantity of stepper motors
I bought in excess).
