  1. Re:Read TFA on Students Call Space Station With Home-Built Radio · · Score: 1

    The plug was originally designated PL-259. The mating socket was an SO-239. These are US Army Signal Corps designators.

    When introduced commercially, they were called "UHF" connectors by the manufacturer, Amphenol. They are actually pretty lousy connectors for anything near the UHF band, though...

  2. Amateur radio is more or less self-sufficient.... on Students Call Space Station With Home-Built Radio · · Score: 1

    , whereas the internet, cellphones, and other "modern" communications systems rely on a shitload of pre-existing infrastructure before they will work.

    Ham radio just needs a radio and antenna at each end, and it works. No telephone companies, backhoe fade, DDOS attacks, etc.

    Not to mention that smoking is only the predominant method of use because it gives the maximum effect from the minimum material. This is important when dealing with an illegal substance, which can easily cost users $200/oz or more.

    If pot were legalized, then it would become much less expensive, allowing users the luxury of using it in less "efficient", but less harmful ways, such as oral consumption.

  9. Re:60 cups on 3 Cups of Coffee Increases Hallucinations · · Score: 2, Informative

    No, he was just explaining the difference between a true hallucination and the alterations of perception caused by LSD or other classical psychedelics. A true hallucination has absolutely no basis in reality (seeing people who aren't there, hearing voices, etc.) The "hallucinogenic" effects of psychedelic drugs generally take perceptions of things that are actually there, and modify them (shifting colors, add movement, synesthesia, etc.).

    The only recreational drugs that commonly cause true hallucinations are deliriants like Datura (Jimsonweed).

  10. Protest Warrior? on Protesters Against Protesting · · Score: 1

    There is a loose organization composed mostly of right wing college students who are known for "counterprotesting" at antiwar rallies and such. They are usually outnumbered by 10,000 to one or more at larger marches.

    Probably because there ISN'T any programming required.

    As far as I can see, this thing isn't really a robot, as it has no autonomous capability. It is just a large RC vehicle with a beer and liquor dispenser on top.

    The only "programming" involved is setting up a bunch of commercial R/C equipment as directed in the manuals.

  13. Here's a "Plug and Play" solution.... on Home Generators (or How DTE Energy Ruined My Holidays) · · Score: 1

    The "GenerLink" is a unit that plugs in behind your electric meter, and incorporates an automatic transfer switch and a twistlock power inlet for the generator to feed into. This allows you to power any and all circuits in your home, up to the capacity of your generator. No separate panels or manual transfer switches to install. You will still need a licensed electrician or utility rep to install it, however, because it involves removing the security seal on the meter. Installation shouldn't take more than 30 minutes, INCLUDING making the extension cord to connect the generator to the unit.

  15. Do you know what "200CK"actually means? on Trick or Treatment · · Score: 1

    It means a dilution of 1 part in 100^200, or 1:10^400. Yes, that's 1 followed by 400 zeroes!

    A dilution ratio like that means that it is unlikely that a single MOLECULE of the duck is actually present in the finished product.

    So yes, the product is nothing but a sugar pill, because the "inactive ingredients" are the only constiutents that are actually there!

  17. Jamming devices are ILLEGAL under FCC regs.... on Wireless Invention Jams Teen Drivers' Cell Calls · · Score: -1, Redundant

    Intentionally interfering with any licensed communication service (including cellphones) is a violation of FCC regs, and will bring down fines on the manufacturer of these things, and possibly people who install them.

    The only way to accomplish this that would be legal would be to turn the car into a Faraday cage (screened windows, etc.), blocking reception PASSIVELY. Anything that radiates a signal of it's own to block reception is going to run afoul of the FCC.

  18. You mean like Model Rocketry? on Does Obama Have a Problem At NASA? · · Score: 2, Insightful

    That has always been a "hands-on" way to interest kids in spaceflight technology. And in the past, NASA used to have a lot of model rocket stuff available on their kids/educational webpages.

    Unfortunately, the US government is now in the process of regulating model rocketry out of existence in the name of fighting terrorism...

  19. Not since Nixon.... on Time To Discuss Drug Prohibition? · · Score: 2, Informative

    and the passage of the Controlled Substances Act of 1970.

    Prior to this, drugs were subject to transfer taxes, but were not actually illegal if the taxes were paid. Of course, the taxes were so high compared to the value of the drugs that nobody ever paid them, making the drugs "effectively" illegal. But the lawmakers up to that point realized that they didn't actually have the power to BAN drugs without a constitutional amendment, so they went with a tax-based approach.

    The controlled Substances Act changed all that. A new "superagency" called the DEA was created from parts of several different agencies, and was given the (unconstitutional) ability to ban whatever substances it saw fit by bureaucratic fiat.

    The statement "Lord, please don't let me fuck this up" was originally referred to as "The Shepard's Prayer", after the first US astronaut, Alan Shepard. He reportedly "recited" it while on the pad awaiting his Mercury flight, not knowing that his mike was hot, and everyone in launch control was listening in.

    Shepard also ended up having to pee in his spacesuit on the pad, because the engineers hadn't considered the effects of having a man lying on his back with his legs elevated for several hours before launch.
