Ooooh! Ooooh! Oooh! I have a copy of an old post describing a self adhesive
plastic sheet which can be run through a desktop laser printer and by
using just about any kind of graphics software than can print to a laser
printer, you can print your design on it and use it for pro-looking chassis
labels, etc. Even though this approach is NOT a stencil, it might be an
alternative worth looking into. Company name is:

	LABELON
	10 Chapin Streen
	Canandaigua, NY 14424-1589
	(800) 428-5566

	The product number is CG-430 and may be available at some printer
	supply stores.

I have never seen or used this product but it seems to be a pretty neat idea.

I am looking for an IC, a Mostek MK5017.  This is a relatively
old chip, used in a Heathkit GC-1005 electronic alarm clock.
I've contacted Heath and a couple of companies (ECG, and SGS
Thomson who bought Mostek) and none sell the 
chip anymore.  Therefore I would be willing to buy a used one
if someone has one.  Please send response by email.  Thank you

Well, I've saved my pennies and am starting to narrow the selctions down to
a few guitars. My problem is that I like them all, so I'd like to solicit
opinions. Please bear with me while I ramble about what I think I want.

I like the Fenders. I like the Strat sound, and the Tele looks. Has anyone
played the Tele with the humbucker? I've played a slim-necked Epiphone all my
life, but think it might be time to go to a 25.5 scale with a bit wider
neck. I've played Strats that I like, but am still a tad concerned if I'll
like the tighter radius down the road. What's the difference between the
Strat and Tele necks, besides the head? How does alder vs. ash affect the
sound? Can you get a rosewood fingerboard on the Tele?

I like the SG. I'll probably pass here because it's similar to what I have
now. I also prefer a translucent finish. It's a shame to have a beautiful
mahogany body and just paint it. Does Gibson offer translucent finishes on
the SG?

I really like the look and sound of the Les Pauls. I've got to nix this one
because I like to work the high frets, and I don't like the way the neck is
attached (clunky).

I've been looking at Carvins. I like the neck-through idea. You can get
either 24.75 or 25.5 scale necks, but only in the thinner Gibson width (1.65
at the nut, 2.22 at fret 24). Choose maple or koa. For bodies you choose
poplar or koa. A cool option is bookmatched flame maple top. Not only is it
beautiful, but I hope would brighten up a koa body neck combo, sort of Les
Paulish. Or a maple-neck/poplar-bout might be Strat-like. They offer several
varieties of pickup configuration, including active electronics. I'm not
sold on the actives, though. I think I prefer to keep the raw pickup sound
available, and have the preamps and such outboard.

I like the Fender and Carvin inline head designs, because a straight shot to
the tuners is just the *right* way to do it. I prefer the symmetry of the
Gibson three-on-a-side design for looks, but it just seems wrong. I've got
one and it's played fine for years, it just bugs me. Carvin used to offer a
three-on-a-side design that was a straight shot, but it's discontinued.
Jackson, I think, missed the boat with their inline headstock that doesn't
put the tuners in line with the strings. I'm sure they play fine, but it
would bug me.

Actually, that sums it up quite nice as the 'only' true way to stop a barking
dog (however, the dog's owner may get a bit peeved ;-) But a more humane
approach may work as well. I used to live next door to a guy that had a Lab
that had a chronic barking problem. Short of using the 'Baretta' approach, I
came up with a sweet solution that worked. I took a high frequency tweeter and
built a oscillator/amp for it that would sweep between 18Khz to 25Khz at 120db
and aimed it at the guys back yard with a remote on-off switch. The dog would
start barking and I would hit the switch then watch with glee as the mutt would
roll around in the grass and rub his butt on the concrete. Found out it was
good for cats as well. One problem though, my wife said she could hear it and
it was like someone running thier finger nails down a black board to her, so
she made me quit using it :-( But it was fun while it lasted.....

Do you by chance still have the schematic for that?  This lady next door to

Simple -- It's the ROM.  If you're building a _lot_ of something, it's
cheaper to simply mount the IC die directly to the PCB.  The bondout
wires are then tacked to PCB traces, and a drop of epoxy is put over
the whole thing for environmental protection.

Most cheap digital clocks and watches are also built this way, also
those musical greeting cards, the "Pocket Terminator", etc.

Obviously, if the thing doesn't work you can't fix it.  But this
assembly technique is only used where the volume is so huge that you
can afford to just toss the rejects.

All you need to do to solve the computer's problem is ground the drawer by
running a wire (any type) from a screw in it's metal to the coverplate screw
on any grounded AC recepticle.

However, this will probably worsen the operator's problem:  getting
zapped. Spray for the carpet and anti-statick devices will dissipate
the charge slowly before it builds up to the "big zap" point.  The
above solution will dissipate the big zap quickly, as your operators
will tell you.

I've always seen anti-static mats with a large (1 to 10 megohm)
resistor in series with the ground source.  You can buy a resistor for
about $0.50 at radio shack, connect one wire to the plug screw and one
to the wire to the drawer screw.  This may (comments from others,
please?) more slowly  dissipate the charge, but is not necessary, at
least for the hardware's sake.

Hi,
   I am trying to build a project which is able to digitise human
   voice by using a microphone input and a small speaker output.
   Since the band width of human voice is no more than 10KHz ( i guess)
   ,therefore I need a antialiasing filter to cut off those unused   
   frequency ( is that right?) What kind of filter is good enough to
   deal with this job? Then the filtered analog voice signal will be 
   digitized by a A/D converter with a sample-hold built-in. My choice
   is National semiconductor DA8020, is it a good choice? 
   Then The 8 bits digital signal will go to a D/A converter( DC8010 )
   Is it a good choice? The analog output will connect with a smoothing
   filter to "smooth" the signal. Finally the message will be played
   back by a 8ohm/4ohm speaker.
   Now, my questions are :
     (1) Are those A/D & D/A  good enough for voice analysis?
     (2) Which antialiasing and smoothing filter is suitable?
     (3) How to interface the microphone with the circuit?
     (4) How to connect the speaker with D/A converter?
     (5) sampling rate = input clock signal ?

This solution has a disadvantage! The power-parallel-pas-transistor

I didn't write the part that you quoted and attributed to me, so I'm the
wrong person to ask.  

As someone else has mentioned in this thread, if you put the axis of rotation
vertical, you have no problems making flat turns, but you will have problems 
on banked curves or (as you mention) in hilly places like SFO where the
pitch of the vehicle can change rapidly.  

I also would expect that you'd need an even number of flywheels, in CCW/CW
rotation pairs, or the vehicle would have a pronounced tendency to yaw in the
direction opposite to the flywheel's spin!

I think that 'black glob' was a mess of epoxy on top of the real chip.  Most likely
to prevent users from taking apart theire cartridges and copying the ROM's for

QST still has some theory, but they get very few hard theory articles, and

Here's two more:
