Congratulations to Vern
Graner on his review of the
Fireball V90 Router kit in the
December ’08 Personal
Robotics column.
I was surprised to see a
CNC machine kit at a price
below $1K. The cheapest I've
been able to find previously
has been over $2K. For
example:
http://buildyour
cnc.com/default.aspx. His article skirts
one problem in the low cost
Cad/Cam/CNC arena. Something you
might want to consider for a future
article, e.g., the cost of the software.
When I acquired my Sherline mill
almost 10 years ago, Sherline didn't sell
a CNC package. (I got mine back then
from Flashcut; they still sell one.) When
Sherline did offer a CNC package, they
went with the Linux-EMC solution for the
same reason that I'm looking at it for my
next system: zero cost. I'm looking at the
combination of Ubuntu EMC, GCAM for
the CAM part
( http://gcam.js.cx/index.
php/Main_Page) and QCAD for 2D
CAD ( www.qcad.org/qcad.html).
I'm still looking for a Linux based
3D CAD package; there are a number
of possible candidates.

I enjoyed your article about the
Probotix Fireball V90 CNC Router.
I make "techno geeky" clocks from
discarded computer parts. I need a
way to customize blank CD-ROMs or
DVDs, and while there may be easier,
less expensive ways, I'm intrigued with
your review. To start with, I've used a
PC with Windows for years and, of
course, DOS.
I have lots of unused computers in
my garage ( 30+) and would like to take
the best/premium one of this group and
possibly convert it to Linux. Based on
your article, the EMC-2 route is a less
troublesome way to go.
Precision Headphone Amp in the June
’08 issue. Could you please tell me what
value and P/N these SMT inductors are?
Bill Mack
Sure! Here you go:
445-1569-1-ND FERRITE CHIP 330 OHM
2.5A 0805 0 0.06700
That's a Digi-Key number and the
price is approx. 67 cents. Good luck!

I could not find the component
listing for L1+L2 in the parts list on your
MODIFICATION A SNAP
Would it be possible to modify
Fred Eady’s October ’08 WIFI Hotspot
project to be USB compatible so it could
interface with Nikon DSLR cameras?
Kirk Davies
Yep. Just put an FTDI USB-to-serial
IC on the board instead of the ST3232
RS-232 part.
