Subject: [alt-beam] easytrax!!!!!!!!!!!
Can someone help me install easytrax? I got it off zoelen's web page.
I extracted it to C:/Program Files/PCB design/ and ran the install program and the install screen came up, and for the destination and source drive I put C and typed in
C:/Program Files/PCB design/ where it asked for the destination path, and I got an error message of invalid path name, I tried a few other paths simaler to the last and it still dosn't work. someone help me.

When I iron it on will the black part or the white part be what the electricity flows through? And do I have to flip it if I have a laser printer, or just if I use a copier?

could send and receive IR signals to each other for detecting food. The
sending and receiving had a 12 inch radius though.
