Getting Started with Propane and Fire Effects
Most propane-based projects only require a basic low-pressure source. You can build one from off-the-shelf parts.

Beginning in 1904, Edward Curtis travelled around North American for more than 20 years photographing Native Americans. While his collection of over a thousand photos housed at the Library of Congress isn’t a precise record of how American Indians lived at the time (he took some liberties in romanticizing the past), it is nonetheless a valuable record of a people largely marginalized by history.

Looking at Fukushima not easy. The place has been evacuated on 2011 after 4 of its nuclear reactors melted down. Tohuku earthquake raised a 13 tsunami meter wave that was just 3 meters too high for the 10 meter wave gate that the power station had in place. The meltdown reached a level 7 on the International nuclear […]

Animated photos from Fukushima show how abrupt its evacuation was after nuclear disaster
It’s happened to most of us – some more than others. You’re driving down the highway or a backroad or maybe you roll through a stop sign one too many times, and here they come. The flashing lights, the piercing sound of the siren. It’s nerve-racking, to say the least.
With so much tension surrounding recent officer-involved shootings, I feel a duty to open the discussion on what to do when legal gun owners either open or concealed carrying are pulled over by police.
No matter what state you find yourself in, national firearms expert and trainer Massad Ayoob explains there is a universal way to inform the officer you’re carrying: hand your concealed carry permit over with your drivers license.
A good idea is to have your licenses, as well as proof of registration and insurance if your state requires drivers to show, readily available to hand the officer if requested.
Watch as Ayoob and PDTV host Tom Gresham walk through a typical traffic stop, explaining why every concealed carry permit holder needs to have an action plan in place so they know what to do if and when they’re pulled over.
Do you have an action plan? Is there anything you want to suggest readers add to their action plan? Sound off in the comments.

You Carry Every Day. Do You Know What to do if You’re Pulled Over?
Milwaukee County Sheriff David Clarke joined Megyn Kelly last night to condemn the response to the Dallas ambush of police officers from Obama, Al Sharpton and Loretta Lynch.
“We have some very irresponsible rhetoric coming from some very powerful people,” Clarke said on air Friday night. “It is time for this nation to stand up with one voice and to condemn and shun this movement called Black Lives Matter.”
Sheriff Clarke went on to say Black Lives Matter needs to be placed alongside other hate groups like the Black Panther Party and the Nation of Islam, saying “This movement needs to be marginalized. We have looked at this stuff, we have peeled back the layers, we’ve looked at the data, we’ve looked at the research.”
When the show’s host tried to object, saying questioning how that would have made a difference in Dallas since the man responsible for the shooting in Dallas which left 7 wounded and 5 police officers dead was not a part of the Black Lives Matter, Clarke dug in.
“He was doing this in the name of Black Lives Matter. He said he wanted to kill white people,” Clarke responded.
“It is time for the liberal mainstream media to stop walking on eggshells and giving legitimacy to these rants, to all this false narrative coming out of this the Black Lives Matter movement.”
“We need to delegitimize this Black Lives Matter movement. We’ve had enough of their nonsense,” the sheriff said emphatically.

Sheriff Clarke: Black Lives Matter Belongs With Groups Like These
Don’t look at me like that. Yes, it’s perfectly legal to build your own suppressor. Following the same process as you would to make a registered and legal short barreled rifle (SBR) or short barreled shotgun (SBS), you can build a device that will make your favorite gun quieter, have some fun and even learn […]

Facebook is clearly very serious about its mission to connect the world and in the process, it has launched solar-powered drones that use lasers to connect to each other and the ground, and more prosaic efforts like new antennas for covering both urban and rural areas. Today, Facebook is expanding this work with the launch of OpenCellular, a new open source hardware and software project that aims to bring a more affordable wireless access platform to remote areas.
“One of the reasons the expansion of cellular networks has stalled is that the ecosystem is constrained,” Facebook engineer Kashif Ali writes. “Traditional cellular infrastructure can be very expensive, making it difficult for operators to deploy it everywhere and for smaller organizations or individuals to solve hyperlocal connectivity challenges. It’s often unaffordable for them to attempt to extend network access in both rural and developed communities.”
Ali previously co-founded Endaga, which worked on a somewhat similar project. Facebook acquired the company last October. He also notes that one of the goals of the projects was to build a system with very little physical footprint and the ability to use already available infrastructure because the cost of the land, tower, power and security for setting up a cellular network is often higher than that of the actual access point itself.
Facebook says OpenCellular will consist of two main subsystems: one for general purpose and base-band computing, and one to handle the actual radio. Both of those systems were designed to be somewhat modular. The radio system, for example, could be based on a software-defined radio or on a system-on-chip solution. While the focus here is on providing wireless access to the Internet over anything from a 2G to LTE network, OpenCellular could also be used to provide a local network, too.
These devices will likely be deployed in rather harsh conditions, so both the industrial and mechanical design aims to make them rugged enough to withstand high winds and extreme temperatures while still being small enough to be deployed by a single person.
Facebook says it will open source the hardware design, firmware and control software for OpenCellular so telecom operators, entrepreneurs, researchers and OEMs will be able to build their own versions. It will also donate the work to the Telecom Infra Project, a Facebook-backed initiative for exploring new approaches to — well — telecom infrastructure basics like access and backhaul.

While Jimmy DiResta always makes his builds look easy, this is one that we might actually be able to do. This month Jimmy builds a massive, eleven-foot-plus farmhouse dining table, using a very limited amount of tools, reminding us that you don’t need a fully-outfitted shop in order to build something as huge and sturdy as this.
Jimmy shows us how he handles one of the most important parts on a table of this size—the corner bracing, which needs to be both sturdy and in this case knock-down. And as always the video is sprinkled with helpful tips, including the easiest way in the world to make boards look weathered. (Hint: Get an assist from Mother Nature.)

DiResta’s Cut: How to Build an Eleven-Foot Farmhouse Dining Table
If you’re going through Game of Thrones withdrawal—and aren’t we all—then you need to watch this video immediately.
It begins as a supercut of the amazing bummers of Jon’s short life (well, lives) but segues into his semi-coronation as the King in the North, all while highlighting the many, many, many times Jon has kicked ass throughout Westeros. It’s astoundingly well done.
I know Jon gets a lot of crap for being emo, but as this video reminds us, he’s put up with some absurdly horrible shit—including being murdered—and still managed to become the most spectacular badass on both sides of the Wall.
