My point exactly. It is Jan Panties that imagines a home-made laser
pointer should be illegal when far more dangerous devices are
readily available.

: detonation with a filament and matchead.

Tell it to Al Qaeda, in point of fact. Perhaps you've not heard
of weedkiller and sugar or the Oklahoma City bombing.

: Most of these kids would have
: the brains to call Uncle Steve, who works in the mines somewhere in
: West Virginia or Pensylvania and have him send them a half-diozen #6
: electric blasting caps to play with, and yes, they are capable of
: initiating a high order deteronation.

: I't ain't rocket science!

It isn't rocket science to spell "Pennsylvania", "dozen", "detonation"
or "It", most middle school students with an IQ of greater than 80
can manage it. Pity you cannot.

:
: Another uncle, a guy that lets say is Ralph

That's where you need the apostrophe, in "let's", a contraction of
"let us".
Have a nice high order deteronation, come back when others will
know what you are babbling about.

You would be surprised - the people who got the shit scared out of them and
had no idea what they were "really" dealing with - and when trying to
convince them it wasn't as they thought - OH MAN! But too - it is the
"Resources" used in such an incident. At the least - the Police and an EMS
unit arrive. Maybe an Engine Company - or worse - a HazMat team and then
some. Sure - it makes for "practice" for the crews, but it is a waste of
taxes for what actually amounts to "false alarms".
So - joke or no joke - the law enforcement folks don't play it that way.
Depending on the situation - you can reasonably figure what it isn't. But
still there are those cases which demand attention - real or imagined
threat.

Invert the phase 180 degrees and it is resurrection laser. Legal? I
think not.


It is legal to build, own and use. Just not in public. The first time
you cause damage to someone or someone's property you are legally, and/or
criminally liable.

Hey! Great way to burn out the receiver in a cop's laser driven speed
measuring instrument.

I am going to build both the laser, as well as the flashlight. I'll put
the flashlight on my bike for a headlight.

Long time, no see AL! Nice to know that you are still around.

How did your eotvos experiment go? Get good results?

Why not? It would certainly be illegal to SELL such a
product without the appropriate warning stickers,
certifications, and such, but making one of your own
from readily-available components? How is that
illegal? Doesn't even look like all THAT powerful
a laser.

More powerful than ANY laser pointer of the class that IS legal.

I am quite sure it is maxed out as well, and will have a very short
lifespan in that set-up. Still, far more dangerous than anything you can
buy for that money. Most start at hundreds of dollars.
I know how to make any number of pretty damn
dangerous gadgets from items available for purchase
in any decent hardware store...but would it be
illegal for me to do so, in general? (Ignoring, for
the purposes of this question, the creation of certain
controlled materials such as explosives.)

Explosives are easy. Implementation is the bitch.

I like the Saturday Night Live skit "He blowed up R E A L good!

They blow up old bands from the seventies.

3) GPS receivers do not have atomic clocks.

Idiot. GPS receivers get their time cues from GPS satellites, which DO
have atomic clocks.

You're a goddamned retard.

The main problem I have with this laser in a flashlight is
that it has no safety, a kid can find it, switch it on, look into it,
and / or burn anyone else's eyes out.
The max power is 1mW here for laserpointers IIRC (EU).

As a terrorist weapon ? No, better get some Pu.


It would likely work even better if the lens section from a real laser
pointer was placed in front of it.

How would you ever move a mine shaft anyway? ;-)

Cheers!

A locally proximal 50 kiloton nuke would likely "move" it.

Imbecile,

The distance to satellite i from the receiver is

Ri = c (Ti - t)

Where

** Ri = This distance
** Ti = Time reading from this satellite
** t = Time reading from the receiver plus offset

We really don't care about the receiver time t because with the
fourth satellite it can be calculated. However, all satellites should
have their time synchronized with each other. The distance from the
satellite to the receiver is also the following.

Ri^2 = (x - Xi - Vxi (Ti - t))^2 + (y - Yi - Vxi (Ti - t))^2 +
(z - Zi - Vxi (Ti - t))^2

Where

** x, y, z = Coordinate of the receiver
** Vxi, Vyi, Vzi = Velocity of the satellite at time = Ti

The velocity of the satellite can be embedded in the almanac
information sent down from the satellite.

So, we have

c^2 (Ti - t)^2 = (x - Xi - Vxi (Ti - t))^2 + (y - Yi - Vxi (Ti
- t))^2 + (z - Zi - Vxi (Ti - t))^2

Since these satellites are very close to ground, we have

** abs(x - Xi) >> Vxi (Ti - t)
** abs(y - Yi) >> Vyi (Ti - t)
** abs(z - Zi) >> Vzi (Ti - t)

With the above simplification, we have a cheaper algorithm as follows.

c^2 (Ti - t)^2 = (x - Xi)^2 + (y - Yi)^2 + (z - Zi)^2

Collecting the information from four satellites at the same time, we
have the following four equations.

** c^2 (T1 - t)^2 = (x - X1)^2 + (y - Y1)^2 + (z - Z1)^2
** c^2 (T2 - t)^2 = (x - X2)^2 + (y - Y2)^2 + (z - Z2)^2
** c^2 (T3 - t)^2 = (x - X3)^2 + (y - Y3)^2 + (z - Z3)^2
** c^2 (T4 - t)^2 = (x - X4)^2 + (y - Y4)^2 + (z - Z4)^2

Or you can use polar coordinate. Anyhow, solve for the four unknowns
(t, x, y, z). You get your position. Again, the time of all
satellites have to be synchronized.

Yeh I watched the video, fucktard. Guess your reading comprehension is as

I'll bet it would light a candle, and there are no lasers that are
"visible" without particulate in the air with which to see them, dipshit.

That's because right along with you being a total mental midget, you

I always thought the DVD lasers were infrared ?
The pinout of a laser pointer is definitely not
the one shown in the movie. The standard pinout
includes amonitor diode. The movie thus likely
is a scam.
