Milo Danger says:
Drones aren't just for the military and government anymore - regular citizens and makers are embracing drones at an amazing rate and creating some very interesting uses for this rapidly developing technology. Milo Danger designs, builds, flies & shoots an armed drone to determine just how safe - or dangerous - these machines are in the hands of a novice flyer.
Hooray for our LA-based friend Tara Brown, co-founder of Los Angeles Makerspace, who is interviewed today on the White House Office of Science and Technology website! She shares about her experience with bringing kids and families into the growing community of American makers. LA Makerspace is a "non-profit community of practice for inventors, builders, and creators (“makers”) to work and learn in a range of areas, including software, hardware, electronics, robotics, art, filmmaking, bio-tech, eco-tech, wearable-tech, and more." And while many "makerspaces" are exclusively for grownups, this one is family-friendly and for makers of all ages.
What inspired you to help lead this effort?
A few different things inspired me. My biggest inspiration is my own two-and-a-half year old. I work with researchers that are focused on the “connected learning” movement and it became very apparent to me that Ripley is going to need more than what is taught to him in school for him to follow his interests. I also noticed that some of the emerging communities for makers in LA might not be the best environment for younger kids, from a safety standpoint. Not too long after that, I co-founded a women's tech club and I thought that perhaps I could combine my own club activities with the need for a more kid-friendly environment.
What kinds of projects demonstrate the promise (and fun) of Making for parents and kids?
All of them! We have a policy where if you are under 13, you must be accompanied by an adult to all of our classes. At first we thought it was a risky move because we weren't sure if parents were hoping to just drop their kids off at classes, but it was the opposite. The parents were just as excited to be at the classes as the kids. Some families have come to almost every single one of our events and always learn something new and mentor the newcomers.
Boing Boing reader Ross "rossindetroit" Hershberger created the Monobox, a nice speaker with a built in amp based on the venerable LM386 IC. MAKE produced a nice how-to video about it for its Weekend Projects program. This is a great project for parents and older kids (I'm guessing 9 and up).
MonoBox is a small, inexpensive powered speaker that amplifies the output of your headphone music player. It's little but it's loud! All the circuit parts are available from RadioShack. The speaker and cabinet are left to your preference.
You'll learn how to assemble and solder an audio power amplifier using an integrated circuit (IC) chip, and how to choose a speaker and install it in a cabinet with the amplifier.
The core of MonoBox is a compact and efficient audio amplifier based on the LM386 power amp chip. It will run on 200mA of current using power supplies from 6V–15V DC. This gives you the flexibility to power it from a wall adapter, a 9V battery, or a car accessory outlet.
You're probably thinking, "Sure, but it's so small. Does it rock?" Fair question. The prototype has been exhaustively tested and it does indeed rock. Maximum volume output is 90dB, and with the added bass boost your socks will be rocked clean off!
"These simple recipes gave me the confidence to try more. And that’s usually what happens, Matt Jabs [co-author of DIY Natural Household Cleaners] says: 'A lot of people just can’t believe that it’s going to work…because we’ve been conditioned through the excellent advertising agencies and commercials they make that (commercial products are) great. But really, it does work. So just start with one project and then go from there. It’s very exciting.'"
The wirelessly remote-controlled Transform Robot took some ten years to develop, and includes wireless internet connected cameras for remote monitoring, and the ability to steer its arms and shoot little plastic darts from them.

With the Jewish Diwali aka Hanukkah well nigh upon us, I was looking to provide my 7 year old son Uriel with a maker angle on the central artifact of the holiday, the Menorah. The Maccabees had hastily hacked together their Menorah by using hollow iron spearheads and I also wanted to capture this improvisational aspect of making the Menorah.
Inspired by Joe Grand's Pipe Menorah we set off to the nearest hardware store to make one of our own.The guys at the store were kind enough to let us putter around gathering the parts we needed and try them out together.

Electronics are contained in box at back waist containing arduino uno, 2 nine volt batteries, and small amp. Speakers are in ends of tube around neck and mic is on an earpiece. Arduino board powers eye stalk and dome lights as well as handles dalek voice modulation. I found the arduino sketch (source and circuit diagrams) can be found here, kudos to Andy Grove for the sketch. Originally created for my wife (the only dalek I will ever love) for the Time Traveler's Ball held at the Redmoor in Cincinnati 11/17/12Photo Link. (Shared in the BB Flickr Pool)
Some pseudoscience is pretty obvious. I think most of us are comfortable saying that the world will probably not end this December, in accordance with any ancient prophecy. But distinguishing fact from fiction isn't always simple. In fact, "fact from fiction" might be too simple a way to even frame the question. In reality, we're sometimes tasked with spotting misapplication of real science. Sometimes, we have to tell the difference between a complicated thing that nobody understands yet very well but which is likely to be true and a complicated thing that nobody understands yet very well but which is not likely to be true.
Basically, it's messy.
Emily Willingham at Forbes has some helpful hints for how to make these distinctions. She offers ten questions that can serve as guidelines for approaching new topics you're skeptical of — questions that, taken all together, can help you see the patterns of pseudoscience and make informed decisions for yourself and your family.
3. What kind of language does it use? Does it use emotion words or a lot of exclamation points or language that sounds highly technical (amino acids! enzymes! nucleic acids!) or jargon-y but that is really meaningless in the therapeutic or scientific sense? If you’re not sure, take a term and google it, or ask a scientist if you can find one. Sometimes, an amino acid is just an amino acid. Be on the lookout for sciencey-ness. As Albert Einstein once pointed out, if you can’t explain something simply, you don’t understand it well. If peddlers feel that they have to toss in a bunch of jargony science terms to make you think they’re the real thing, they probably don’t know what they’re talking about, either.
9. Were real scientific processes involved? Evidence-based interventions generally go through many steps of a scientific process before they come into common use. Going through these steps includes performing basic research using tests in cells and in animals, clinical research with patients/volunteers in several heavily regulated phases, peer-review at each step of the way, and a trail of published research papers. Is there evidence that the product or intervention on offer has been tested scientifically, with results published in scientific journals? Or is it just sciencey-ness espoused by people without benefit of expert review of any kind?

At Acculturated blog, Abby W. Schachter writes about "bobos," short for bourgeois bohemians, and evidence that big consumer brands are now marketing to them with highly mockable DIY gear that re-creates artisanal (or, depending on your point of view, obsolete) food production methods.
Case in point: William Sonoma's new upscale DIY kitchenware collection, called the Agrarian Guide, where one can purchase "a reclaimed rustic chicken coop for $759.95... a Warre beehive made from “untreated Western Red Cedar” that retails for $399.95, a vinegar pot for $90, an $80 fermentation pot to make “your own sauerkraut,” and a hand crank Burr grinder grain mill retailing for $675.95. The accompanying grain mill clamp will set you back another $105.95."
I vacillate between coveting everything in the catalog, and wanting to mock everything in the catalog. Either way, I cannot wait for the Portlandia sketch.
