This product is called "Uranium Ore"... There is an interesting/funny comment, though.

Kyle J. Von Bose says:

I bought this to power a home-made submarine that I use to look for prehistoric-era life forms in land-locked lakes around my home town in Alaska. At first I wasn't sure if this item would (or could) arrive via mail, but I was glad to see it showed up with no problems. Well, almost no problems.

Unfortuantly my mom opened my mail, because she does not respect people's privacy. She was pretty upset to see Uranium Ore. After a long argument and me running away from home again, she finaly stopped being such an idiot and I was able to get back to work.

The quality of this Uranium is on par with the stuff I was bying from the Libyans over at the mall parking lot, but at half the price! I just hope the seller does not run out, because I have many projects on my list including a night vision sasquatch radar, an electromagnetic chupakabra cage, a high velocity, aerial, weighted Mothman net and super heated, instant grill cheese sandwhich maker.

I liked the negative reviews of sara lee yellow cake mix: "total rip off, would not enrich to weapons grade!"

"Did not make my canoe go any faster, December 13, 2007

By Lex10

Ungainly shape and small size proved to cause wet hands and canoe actually seemed to go slower. I'm not sure if there's any connection, but there were a lot dead fish floating on the way back. Very bad ore."

I laughed at some of the "Customers Who Bought This Item Also Bought" items:

* Forbidden LEGO: Build the Models Your Parents Warned You Against!

* Hasbro Nerf N-Strike Firefly REV-8

* Balls of Fury (Widescreen Edition)

* Dremel 3956-02 MultiPro Super 1.15 Amp 5,000 to 35,000 RPM Variable Speed Rotary Tool with 77 Accessories

* Art of Computer Programming, Volume 4, Fascicle 4,The: Generating All Trees--History of Combinatorial Generation

* (a bunch more programing books)

The "Customers Who Viewed This Item Also Viewed" section is also great. A side-effect of Amazon's recommendation engine is that it groups all the unlikely products and humorous reviews together. Here's a gem of a review on the page for the (discontinued) gallon of Tuscan Milk:

Wait until you own up to having this thing and using it, you'll find yourself waking up in hospital wondering why.

Bjoern• 17 years ago

What do you mean? That the device will make you sick or somebody else will beat you up?

jacquesm8• 17 years ago

You are interfering with the ability of others to communicate, it is the same as gagging everybody around you, which is about as rude as you could possibly get.

When somebody wonders out loud why their cell doesn't work, especially if the call they need to make is an urgent one and you whip out your 'gadget' be prepared for nasty stuff to happen to you.

Interfering with any kind of communication is about as low as you can go in my book (other than doing violence to other people), doing it on the sly makes it one step worse.

onreact-com• 17 years ago

Does selling products on HN conform with the TOS?

almost• 17 years ago

It seems unlikely that the poster is the one selling this item. It seems more likely that the reason for posting this was to show that you can in fact now buy cell phone jammers for only a few dollars. This is quite interesting whether or not you actually want to buy one :)

affiliator2• 17 years ago

While I'm not begrudging, it should be noted that DX links ending with ~r. and a number are affiliated to a particular user's account.

makmanalp• 17 years ago

I bet a ton of highschool professors wish they had one of these.

jcl2• 17 years ago

Apparently they are in wide use in Chinese and Indian schools.

alaskamiller• 17 years ago

I have this sitting on my desk right now. I got it a year ago. Unfortunately it doesn't work, or I'm too dumb to get it to work, but other people on the DX forum mention that you have to tweak it. Anyone want to buy mine and give it a shot? $20 shipped in the US. I'm serious.

ars2• 17 years ago

Instead of jamming the signal, how about spoofing the various protocols (i.e. make a micro-cell), but one that will connect all calls with silence.

Would take much less energy, since all you need is to be slightly stronger than the cell tower, plus you don't need to transmit all the time, just when there is a call.

For extra points, detect and forward calls to 911.

eli3• 17 years ago

Huh? How exactly did you conclude that it would take less energy to build a fully functional mobile cell phone tower that supports a variety of incompatible protocols, all of which are secured with non-trivial encryption?

Even without the encryption, it is extremely difficult to demodulate a GSM signal

ars2• 17 years ago

Perhaps you have a different meaning of the word energy? It will certainly take less radio energy to do what I suggested.

And as for GSM, have a look at http://mobile.slashdot.org/story/09/08/17/0014235/Open-Sourc...

These are apparently illegal to use in the U.S.

DanielStraight2• 17 years ago

And for good reason. Who wants to have their cell phone rendered useless just because they happen to be standing too close to someone who decided they're more important than everyone else around them.

sho2• 17 years ago

Similarly, it's a good thing dangerous chemical kits are outlawed in the US. Who wants to have their house burned down just because they happen to be living too close to someone who decided they're more important than everyone else around them?

update: Hey, why am I being voted down? Not trying to be a douchebag here. I really do view EM freedom as strongly correlated with normal-speech freedom. "Pirate" radio stations anyone?

Clamping down on "rogue" EM radiators is like clamping down on "rogue" anything else. We need a broader definition for "freedom of speech". EM is speech, too.

a-priori• 17 years ago

This is especially true in emergencies.

antonovka• 17 years ago

While I don't disagree, I find the opposite idea amusing. Who wants to have their consciousness and conversations disrupted by a loud cell phone user who decided they're more important than everyone else around them?

tedshroyer• 17 years ago

Small bit of info from the FCC:

"The manufacture, importation, sale or offer for sale, including advertising, of devices designed to block or jam wireless transmissions is prohibited. 47 U.S.C. Section 302a(b)."

chunkyslink• 17 years ago

This is illegal but guns are not

slackerIII• 17 years ago

It is in fact illegal to use a gun to interrupt cell phone conversations.

sho2• 17 years ago

Coincidentally, I received two envelopes from DX today! I love that site and would like to vouch for their legitimacy. However, do be careful - if it seems too cheap to be possible, it's probably fake, just like my "Sandisk" Micromates microSD USB adaptor which is rather different from the Australian-bought genuine article sitting next to it.

yb• 17 years ago

Probably beyond the abilities of a typical hobbyist: http://www.ladyada.net/make/wavebubble/index.html but since this is Hacker news.

gamache• 17 years ago

Limor is a first-class hacker and this is a first-class hack. I was present when, a couple years back, she used her Wave Bubble to prevent interruptions to a wedding ceremony. It worked perfectly, and upon shutting off the jammer, there was the sound of voicemails arriving to a number of the guests. Bullseye.

quellhorst• 17 years ago

I saw this demoed at SXSW, I was maybe 50 feet away and it didn't jam my cell.

yan• 17 years ago

Way cooler: http://www.ladyada.net/make/wavebubble/index.html

nfriedly2• 17 years ago

Does anyone know how to make a cellphone booster? I'd love to be able to get a bit more range out of my cell...

zaph0d• 17 years ago

I went ahead about bought one right-away.
