headphones are a reality. And I'm
happy to report that their prices are
coming down. In MCM's (800-543-
4330; www.mcminone.com) most
recent catalog, they advertise Pro-Luxe noise-canceling headphones for
just $24.95 (Order# 35-1115) — a far
cry from the $299.00 that Bose is asking for their QuietComfort noise-canceling headphones. I haven't had a
chance to test them, but for the price,
it's worth a try. Even if they aren't per-
fect at canceling noise, you still end
up with a great pair of headphones.
Q & A Editor
In the June 2003 issue you suggested that I use the free AutoTrax
PCB layout program. I do not have
Internet access but managed to
obtain a copy on CD from my brother. I printed out and read the
README file but it's not an operations manual. Where do I get the
instructions on how to use Auto Trax?
In the same issue, you mention
that Futurlec ( www.futurlec.com)
will make PCBs up to 30mm by
30mm. That size limitation is totally
impractical. Is it possible it should
have read 30cm by 30cm?
You can find the manual on-line
at the following website:
And yes, that was a typo. The
board size is 30cm by 30cm priced at
$0.03 per square centimeter, or $0.20
per square inch.
