TI-84 program for simpifying radicals into a form like number plus rad(9) ?

I already have a program that simplifies radicals but dont feel like adding on a feature to take in consideration of things being added to it or subtracted from it. Anyone know of a site that has the source for a program like that, if not i guess i will just have to do it myself.

Solidworks shows Mass Different from Reality?

Hi, When I check the mass properties of a model it gives me some weight (mass). When I weigh the actual product the mass is radically different (about 10-15 grams). Anybody had this problem? Can Solidworks be trusted regarding mass properties? Thanks, Yair.

How new data can substantially alter interpretations -- placoderm evolution

An article in Nature (PDF below) reports on the discovery of internal embryos in placoderm (armored fish) fossils. Besides being interesting, these otherwise mundane discoveries have the possibility to radically alter our interpretation of the origin and relationships of early vertebrates. Here's the "News and Views" editorial on the research article, which is more accessible to non-specialists than the original paper.

Nanotube Radio

Nanotube Radio: Supplementary materialsK. Jensen, J. Weldon, H. Garcia, and A. ZettlDepartment of Physics, University of California at BerkeleyCenter of Integrated Nanomechanical Systems, University of California at BerkeleyMaterials Sciences Division, Lawrence Berkeley National LaboratoryBerkeley, CA 94720, U.S.A.We have constructed a fully functional, fully integrated radio receiver, orders-of-magnitude smaller than any previous radio, from a single carbon nanotube. The single nanotube serves, at once, as all major components of a radio: antenna, tuner, amplifier, and demodulator. Moreover, the antenna and tuner are implemented in a radically different manner than traditional radios, receiving signals via high frequency mechanical vibrations of the nanotube rather than through traditional electrical means. We have already used the nanotube radio to receive and play music from FM radio transmissions such as Layla by Eric Clapton (Derek and the Dominos) and the Beach Boy's Good Vibrations. The nanotube radio's extremely small size could enable radical new applications such as radio controlled devices small enough to exist in the human bloodstream, or simply smaller, cheaper, and more efficient wireless devices such as cellular phones....This is the site of the original article

A strange new beast in the particle bestiary?

  Interesting article from the BBC website :- A particle accelerator in the US has shown compelling hints of a never-before-seen particle, researchers say.  The find must be more fully confirmed, but researchers at the Tevatron are racing to work through existing data.  If proved, it will be a completely new, unanticipated particle; researchers say it cannot be the much sought-after Higgs boson.  It could also signal a new fundamental force of nature, and the most radical change in physics for decades. The full article is HERE.

Why is it whenever I want to download podcasts to my ipod nano from i tunes it will only receive two of the 7 podcasts?

So, I have a radical pink shiny i pod nano & I have always downloaded podcasts to it but then I decided to lie of the podcasts so I deleted them all. Now I am back into the podcast thing and I am trying to sync podcasts to my rad i pod but it will only recieve 2 of them. I know that my gigabytes are not all taken up and I am getting SO infuriated!

Paper Batteries

Has anyone read anything about the up and coming Paper (thin) batteries ? Paper Batteries: A paper battery is a flexible, ultra-thin energy storage and production device formed by combining carbon nanotubes with a conventional sheet of cellulose-based paper.A paper battery acts as both a high-energy battery and supercapacitor, combining two components that are separate in traditional electronics. This combination allows the battery to provide both long-term, steady power production and bursts of energy. Non-toxic, flexible paper batteries have the potential to power the next generation of electronics, medical devices and hybrid vehicles, allowing for radical new designs and medical technologies.What do you think? Will it replace these monsters one day?

Thoughts on painting a toilet seat?

Hey folks! I wanted to tap the collective mind of the Instructables community on this one: We recently did a radical redecoration of our bathroom. One of the only things that wasn't touched so far was the toilet. Rather than getting a new (probably boring) toilet seat- I'd like to try painting the old one (I'm talking about the SEAT here, not the cover). Is it feasible for a long-term part of the bathroom, do you think? I've never really painted anything like this before- what paints / techniques would folks recommend? I was thinking of sanding down the surface, applying a rust-colored enamel (with some black patterns), and then a goodly amount of clear coating. Appreciate any thoughts (even if they are "Hey, that won't work- suck it up and sit on a boring seat like the rest of us"). Obviously any work will be documented and submitted to the site : ).

Bit of Fun- Wilhelm Scream

How many movies have you seen that contain this classic easter egg? Don't know what it is? You've probably already heard it a few times before. Every time I go to a movie I enjoy searching for this sound-clip. When I find it, I normally turn to my friend and say did you hear the Wilhelm Scream? I normally get a blank stare followed by The what?'Course I'm the one that studies and analyzes movies' camera shots, angles, etc for fun. Fact: ever wonder why you get so bored watching old movies? Nowadays in entertainment, the human brain gets bored after only five seconds. This means that shots can not be longer then five seconds without a cut, angle change, or radical camera movement. Back then, the limit was ten agonizing seconds. Try it yourself; next time you see a (relatively new) movie, count the seconds before a cut. You'll rarely get past five. In The Bourne Ultimatum, I barely got past three!

Back-room inventors' contest.

From the Popular Science website: World-changing devices don't need to come from big labs funded with big money. Sometimes radical technological innovations roll, whir, or fly out of basements and garages. Do you know you've invented something that's poised to disrupt a market, or have you toiled building prototype after prototype in your home workshop to prove your idea works? Whether you're a professional engineer working on a self-funded side project, a hobbyist who has launched a successful crowdfunding campaign to refine your gadget, or an obsessive teenager who's built a sellable product in your bedroom, please tell us about it! Enter the seventh annual Popular Science Invention Awards. We’re looking for game-changing products developed by passionate, independent inventors -- not academic or corporate R&D; labs. Popular Science editors will pick 10 entries that best represent the spirit of homegrown ingenuity and solve real-world problems in a practical, innovative way. Then, in our May 2013 issue, seven million readers will get the first look at the winners. This is right up your street, Instructablers, because you have to make a thing, that you can show working, and you are not allowed to enter if you have a commercial or university research department backing you up. Link for more details.

Extreme Futurist Festival 2012

The END OF THE WORLD at www.extremefuturistfestival.com the VORTEX IMMERSION DOME 450 South Bixel Street, Los Angeles, CA 90017 featuring SURVIVAL RESEARCH LABORATORIES show Extreme Futurist Festival is a 2 day arts and technology festival focusing on radical voices of the new evolution. Last year we had a great event and were called "a TED conference for the counterculture" by the LA Weekly. This year we seek to make XFF an even more epic experience. People are going insane over the Mayan calendar hype about the world ending on 12/21/12. This is why we have decided to bring them the apocalypse they deserve. We are throwing an end-of-the-world conference that you will not forget. Children get in free. We will be focusing on cutting edge science and technology along with transgressive performance art and music. Showcasing the most innovative and subversive memetics of our time, we see to highlight an extreme future that breaks the formula of modern culture. The future has been commodified by the mainstream in an effort to make revolutionary technologies easy to digest. As a result we are now living in an era of complacency, in which the true leaders and game changers are made to feel like outsiders. It is time to rise against the dominant current of our society and declare that nothing is too extreme. We refuse to be assimilated into a carbon copied version of a new humanity. As evolutionary agents we will push the boundaries of what it means to transform our species. XFF is organized by Rachel Haywire, Christopher Jannette, and Sean Humphries.

May 2019 site changes: my observations and thoughts

In early May 2019, Instructables' website has been radically reworked with a revamp. Changes I have observed include:Navigation: Many categories and subcategories have been eliminated and instead reworked under other folders as part of the changes (there is no "Play" category and subcategories such as "NERF" and "Paper Airplanes" no longer exist) "Recent" filtering is not directly available to people browsing the site--you must sift through the categories and get through at least two pages to find a way to filter the selected category for "recent" (i.e. Homepage -> Circuits -> Projects -> (Page at which you may select "recent")) There are no filters for searches On the front page and in the categories' main pages, featured projects are emphasizedThe Forum/"Community": Without manually typing in the URL, there is no direct way to access the "community" page Buttons to access the forum among in the category pages are tied to the community pages for that category (as a result. They do not allow you to see the general forum posts of the community without viewers manually deleting the category from the URL and going from thereThe way people navigate about sites controls what they can see and how they see if, so all of these things will change the flow and behavior of Instructables' viewers versus how it was before. Versus before, it is more cumbersome for viewers to get to recent content while featured content is more readily available. This will influence where people go and what they see.----------------------------------What do I believe this means for the future?Drawing on my decade of experience on this site, I suspect viewership of non-featured Instructables will drop. Thus, the viewership gap--between those projects that have been featured and those that have not--will then widen.Of these changes I think people will say you either "get featured or get buried."

The Kids Are Alright

Via The Sietch BlogIf I asked you if giving up your car and plane travel (permanently) was a sensible solution to global warming, most people of adult age (lets say 20+) would have a hard time doing that. However the next generation, the ones who are really going to be screwed by the ill effects of the global climate crisis see things a little differently."new generation of green teenagers are prepared to support radical measures to help the planet, says a new study.A survey of 16- to 19-year-olds by the Future Foundation found more than one in eight (13%) supported a ban on travelling by air for leisure purposes, while one in 10 say they would back a ban on cars if global warming continues to worsen.Almost 10% even say they would be prepared to take part in guerrilla activities carried out by environmental groups.Meanwhile others - primarily girls - are so eco-conscious they have developed a whole new strand of teen insecurity: "green angst", defined as anxiety about one's eco credentials. Others said environmental awareness even influences their choice of friends and partners.The report was conducted on behalf of the National Lottery to inform funding of environmental projects."It might sound like these kids have lost their minds, supporting guerrilla organizations?! But when you consider the kind of world they are going to inherit it makes perfect sense. If you knew that your parents generation was going to leave you a doomed world, you might be a little pissed. No one wants to grow up to inhabit a mad max movie.According to the study released today by The National Lottery (UK organization), half of 16-19 year olds (50 per cent) want plastic bags banned completely, 71 per cent think that unnecessary packaging on food should go, and 13% per cent want a ban on traveling by plane for leisure purposes. While a quarter (24 per cent) think there should be increases on the taxes and tolls affecting cars, one in ten is prepared to go even further and would support a complete ban on cars if global warming continues to get worse.Read more here.

The Bare Conductive Touch Board is LIVE on Kickstarter

Hi Everyone! Just wanted to let you know that our Touch Board is up on Kickstarter, make sure to check it out! You guys have done such amazing stuff with our Electric Paint, we can't wait to see what you do with the Touch Board.  The Touch Board is a way to turn almost any surface into an interface.In the last two years, you have have shown us that there is a real interest in developing unexpected interactions with our Electric Paint among other materials. We decided to make the electronics a whole lot simpler by developing the Touch Board. It is an Arduino-compatible board with a specific capacitive sensing chip and an MP3/MIDI player on board. Check out the Kickstarter page for all the details. There is a ton of cool stuff about the board, but it basically boils down to three points: Radical Interfaces: The Touch Board uses capacitive sensing to turn any conductive material into an interface. Imagine light switches painted on the wall with our Electric Paint, interactive books or hidden sensors that can detect a whole person. The Touch board can also be used to create distance sensors which work from up to 20cm away - which is as cool as it sounds. No Programming Required: We'll be shipping the Touch Boards pre-programmed to turn touch into sound so all you'll need to do is plug in a micro USB cable or LiPo (we've built in onboard charging) and a speaker and you're ready to go. Touch any one of the electrodes and the MP3/MIDI player will play the associated track from the supplied microSD card. Changing the sounds is as simple as changing the card. Arduino-compatible: We wanted to make sure that this board was easy to use and had as wide an audience as possible so we based it off an Arduino Leonardo. It can be programmed in the Arduino IDE, it works with most shields and it can act as an HID. We're proud to say that we're part of the new Arduino at Heart program. Working with Arduino has been great and they're fully behind the Touch Board. Check out our campaign for a lot more info and let us know what you'd make with the Touch Board! THANKS! - Bare Conductive

two in one: How to work with transistors and how to use a 24v system in a car and a 12v? Answered

1: So I have been playing with transistors, awesome little woks of science aren't they!?  Well everything I have done has been arduino based with the same voltage switching as the transistor's input.  Now of course there has to be a way to send more voltage across than is used to do the switching, but how do you add a ground and prevent that high voltage from entering the controlling circuit.  The basic idea is using an arduino to operate a transistor which controls a 12v DC light source.  Lets assume the arduino can't handle 12 volts and can only get up to 5v which is the highest supplied voltage.  Can a simple resistor attached to the emitter side work? I still feel like the voltage potential on the emitter would be too high for this to work, but I am new to transistors, any wiring diagram recommendations.  I have been through amplifier diagrams, but its too confusing to pick out just what is going on with the transistor, and the most important factor of why. 2: I was looking at aircraft lamps today for the sake of improved vehicle lighting, its quite popular around here, but the majority are 24 volts, at least they are on the brighter end of the spectrum.  Now I know you could use two 12 volt batteries and get the 24 volts and also just pull isolated power from one, (i think) to run the 12v system.  The problem I see is when applying voltage from a 24 volt alternator, It could potentially bring the 12v system voltage above desired levels right?  There isn't a high power easy 12v limiter is there either.  So would these require two completely separate systems along with 3 batteries or are there other ways of handling this task which allude me. Bonus: for all those light lovers check out these incandescent beasts!: http://www.normanlamps.com/index.php/cPath/473_53 Oh no, now I realized these are PS type, there goes those radical fun ideas.  Would this mean probe start or pulse start, and if so how do they work?

Dual energy generation with magnetic Seesaw system and gravity with the help of 3 volt toy motor

This technology is based on  a Seesaw system and magnetic repelling principle Linear motion  .We can generate electricity with very little force with the help of this technology.This will be a radical step in the field of energy generation. In this technology there will be a balance system and two heavy weight magnets(high strength NEODYMIUM MAGNETS) will be attached with each side of this balance system as per diagram. As per diagram there will be two moving weights and these moving weights will move on tracks.These tracks will be fixed at the angle of 8 to 10 degree. Two magnets will be attached on the front side of these moving weights and these magnets will have similar polarity with the magnets of balance system. These moving weights will be attached with two gear boxes and these gear boxes will be attached with two generators. HOW THIS TECH WILL WORK? When one side heavy weight magnet of balance system will be pressed with the help of any kind of external force then this side will come down and repel its side moving weight due to equal polarity of magnets.due to repelling the moving weight will move forward .but when the heavy weight magnet will move upward then this moving weight will move backward due to gravity to get its position back. in this way this moving weight will work to run a gear box and this gear box will work to start a generator to generate energy. This balance system will also work to pass through their side copper coil due to linear movement and in this way this technology will generate Dual energy. WE will take very high strength NEODYMIUM magnets  for balance system. I would like to insist on some following points (1) The balance system will be attached with 'L' form crank with external PRESSING source. (2) The moving weights will also be attached with 'L' form crank with gear boxes. (3) Each side magnet of balance system will work one by one .When one side magnet will come down the another side magnet will move up .These magnets will come down and move up one by one to repel their side moving weight. (4) We can take as much weight as we can of these magnets of balance system .(500 kilogram to 1000 Kilogram or more) to pass through the heavy coils having 100000 turns or more.  (5) External source of pressing this balance system could be anything such as pressing with foot  or solar cell. WE WILL NEED ONLY 3 VOLT EXTERNAL ENERGY TO PRESS THIS BALANCE SYSTEM  AND GENERATE MORE AND MORE ENERGY.

User profile pages have been changed, for the worst

Instructables has reworked user profile pages in a radical way. Profile pages are now wholly different from what they used to be. Content is no longer divided by its type (instructable, forum, comment, favorite, etc.), it is divided into two sections: the user's projects...and everything else. The section on everything else encompasses every activity related to the user in question. This cluttered list of activities can include everything from viewers favoriting the user's projects, replies to the user and even (deleted) spam comments left on the user's projects. There is no way to divide things up to look at them by their individual types--you must sift through everything manually. As far as the user's content goes, only five projects are visible to the marauding viewer at a glance. There is no indication to viewers over how many projects have been posted by the member in total. Versus the previous layout: Fewer projects are being shown The total number posted by the user is now unclear The number of subscribers had by the user is now unclear The 5 projects which are shown are displayed with smaller images than before. Absolutely every aspect of presentation was superior under the old layout. The only vaguely positive new development is the ability for an author to control what five projects they desire to spotlight. In light of the massive costs, it is not a major plus. If the viewer does make their way to the page which carriers all of a user's projects, they will again find its contents unfiltered. There are no filters to weed out content by featured status, views or popularity. There is still no indication of how many projects there are either. Patches do not appear to be of any value anymore, as they are nowhere to be seen on profile pages. ------------------------ This change has destroyed profile pages. I have been around Instructables for many years and have seen many layouts--this layout is, without a doubt, the worst yet. The layout of profile pages must be reverted to the previous style. Content is being downplayed like it never has been before. Most of a person's profile page is now dedicated to what other people have done. Users' profile pages--what were once pages dedicated to their stuff--are now dominated by others' stuff. When a user goes to my profile page, I want them to see what I have posted. That is why they went there--to see my content. They are not there to look at others' content. Under this new layout, viewers will have to work harder to find results on these profiles and are more likely to lose interest in the content of the user. The lack of intuitiveness to the layout will only aggravate and put off viewers. Content creators will probably bear the brunt of the fallout of this change if it's not quickly undone. Interest in and viewership of their content will likely decrease in time if things do not change. In turn, content creators may decide not to withdraw and discontinue sharing their works. Whomever made the layout what it is now may have had the best intentions. However, it is time to accept the fact that the new layout is completely inferior to the previous one and that it needs to be scrapped.

Ionizing vs. non-ionizing radiation, units, and safety (updated)

Note: This was originally intended as a reply in the Americium-241 Science forum topicWhen people talk about "radiation," they are referring to many different things, and are probably thinking of some things that don't even apply. "Radiation," the invisible energy given off by radioactive materials, can be either "subatomic" particles or electromagnetic. The most common particles emitted are "beta rays," high-energy electrons, and "alpha particles," helium nuclei. Some sources can emit neutrons, protons, or "positive beta rays" (anti-electrons, or positrons), but those are much less common.The units we use to measure radioactivity are becquerels (Bq, decays per second) or curies (Ci, 3.7 x 1010 decays per second). Since the effects of radiation depend on their energy, another unit of interest is absorbed dose, the energy deposited per unit mass of target, measured in grays (Gy).Safety experts classify radiation into "ionizing," meaning there is enough energy to knock electrons out of atoms or molecules, and "non-ionizing." Infrared and ultraviolet light are non-ionizing, as are neutrons. Alpha particles (helium nuclei), beta particles (electrons) and gammas (as well as lower energy X-rays) are all ionizing radiation. The three have substantially different effects on biological systems, even at the same absorbed dose. Consequently, for radiation safety purposes, scaling factors are applied to produce numerical measures (sieverts, Sv) of "effective" or "equivalent" dose, that can be compared across different kinds of sources.Here's a small table with information for some commonly encountered sources. Isotope Source Activity Dose rate Am-241 smoke detector 35 kBq (1 µCi) 11 µSv/yr @ 1m Te-99m MRI contrast 740 MBq (20 mCi) 1.6 Sv/hr @ 1cm C-14 atmosphere, body 0.23 Bq 10 µSv/yr K-40 bananas, body 4.4 kBq 200 µSv/yrWhat you should see clearly from this is that the natural radioactivity in your body is comparable or larger than that in a common smoke detector. At SLAC, the limit for exposure to sources at the lab by most staff (including me) is 20 µSv/yr (5 mrem).As I noted above, neutrons are sometimes lumped in with ionizing radiation in non-technical "radiation safety" classes (we call them "the photon is your friend" training :-). That is not really accurate -- neutrons don't interact with electrons(*), and so cannot ionize directly. They can interact with hydrogen nuclei (protons), knocking them out of complex organic molecules, and leave behind ionized fragments and free radicals. The can also be absorbed by otherwise stable nuclei, making them radioactive; those new nuclei may in turn give off ionizing radiation.Neutrons lose energy much more slowly in passing through material, and so can penetrate much farther than ionizing particles or gammas. The nuclear interaction [http://en.wikipedia.org/wiki/Cross_section_(physics) cross-section] is much more important here than dE/dx (ionization) energy loss. Materials rich in carbon and hydrogen (for example, paraffin) are far more effective at neutron shielding than dense metals like lead.(* for the expert readers) Yes, there is n-e scattering through W and Z exchange, but the cross-section and energy scales are completely irrelevant to this discussion.

12v solar panel/battery setup project- NOT lead/acid

Hi, I have a project that I'm trying to design/build and could use some help/advice with some of the electrical theory. I feel like this should be really simple but I'm having a lot of issues. I have done a lot of googling but can't seem to find applicable answers so I started my own thread. Any help will be greatly appreciated! If I can solve this, I will be happy to write up a detailed instructable so that others can use this information as well.  The short version: Trying to build a lightweight solar panel>battery pack>UHF radio charging setup. Nominal voltage is all 12v. I'm having difficulty regulating amperage between the units. The long version: My friend is in charge of a campsite which needs to have a 2-way radio on at all times. They need to be able to charge these radios on-premise because they are out there for a little over a week at a time. A solar panel seems ideal for this application. The whole charging setup needs to be lightweight since it is a >10 mile hike into the campsite. Ideally, I would like to use an array of NiMH AA batteries because they are small, relatively cheap, and can be replaced easily if there is an issue. I am also under the impression that they handle repetitive charge/discharge cycles well. I am not married to that though so if there is a compelling reason to use lipo or something else, I am open to that. The radio: is a Motorola Radius CP200. The wall charger that comes with it outputs 14v at 1.5 amps. The battery in the radio (according to the sticker on it) is 7.4v 16.21Wh lithium ion. Setup 1 that I've been trying: I have a 12v solar panel charging a pack of AA NiMH batteries. I started with an 8-pack holder but moved up to a 10-pack to increase voltage and total mAH a little. I've been using little voltage regulators in between the solar panel and the batteries as well as between the batteries and the radio. These function as diodes and help me get the correct charging voltage. My problem is that I can't regulate the amperage. The battery pack will pull as much as it can from the solar panel, and the radio will pull as much as it can from the battery pack. What ends up happening is when I first plug the radio into the battery pack, it works fine. But after a couple minutes, the amperage skyrockets to like 3 or 4 or more amps. The voltage regulator hits some sort of thermal protection limit and the whole thing shuts down. I tried throwing this amperage regulator in there as well to keep it below 1.5 amps, naively thinking that it would just affect the amperage and not the voltage. But what happens is when it's in constant amps mode, it just cuts the voltage to compensate and keeps the total power the same. Setup 2 that I've been trying: I thought maybe since I was having issues with the 'smarts' of these batteries charging and discharging, I would switch over to USB battery packs since they have a lot of built-in protection circuitry. I got this solar charger, an older version of this battery pack, and used the same voltage regulators to step up the voltage from 5v to 14v to charge the radio. I get the same issue of high-amperage discharging of the battery pack. I tried using this step-up converter between the battery pack and the radio but it doesn't seem to work or maybe I'm not using it correctly (I can't seem to get the adjustment pots to actually do anything...). It seems like I'm thinking about current wrong or something. Any suggestions or insight into what's wrong with my approaches would be super helpful. If anyone has any suggestions for radically changing my approach, I'm open to those as well. Thanks for reading!

The golden age between the first terror attack and the last.

Two nights ago at the MOMA I got the chance to catch Weimar NY (A Golden Gate Affair). I had my reservations at first, but my girlfriend kept insisting it would be absolutely marvelous darling and, in fact, it was. For those of you like myself who probably had never heard of this before, Weimar NY is a cabaret, burlesque, gender-bending, performance art, radical left-wing, extravaganza celebrating "the golden age between the first terror attack and the last."Having been part of post-9/11 New York I can honestly say that this is something that could have only developed as a response to that time-period. It's a document, celebration of and response to a certain amount of uncertainty, fear, depression and general hopelessness that descended upon New York after the fall of the towers and to that effect is still somewhat relevant today even if and especially because the face of the city changed after that morning. Something became different when all of a sudden the rest of America became New Yorkers.I think Penny Arcade (an infamous and outspoken ex-Warhol Superstar) summarized it best when she pointed out the difference between New York City and San Francisco. As she saw it, both places were filled with annoying disgusting tourists, but in San Francisco they leave. I think what she means by that is after 9/11, when all of a sudden everyone thought they were a New Yorker, there was a sudden influx of new migrants to New York different from all previous migrations. Again, as she also states, it used to be that people went to New York to reinvent themselves and now they were coming to reinvent New York and turn it into a suburb no different from any other. And it's out of this feeling that Weimar NY grew. It grew out of the alienation of the freaks, geeks, criminals, anarchists, drag queens and general delinquents that used to flood to Manhattan to be at home that were being pushed out by the influx of chain stores, Chase Banks, Gucci wielding bleach-blonds, meatheaded corporate-types and every other boring sort of mediocrity that usually just stayed home in its suburb. Personally this hits home because I grew up north of the city in the suburbs and the first chance I got to escape the suburbs I fled to New York City to be amongst the socially delinquent part of society. I was fortunate enough to get there just before anyone outside of the city knew who, what or where Brooklyn was, when the Moldy Peaches were still playing house parties and the Yeah Yeah Yeahs hadn't accidentally formed one evening in some bar on the LES (and for that matter no one referred to the Lower East Side as "LES" and you could still get stabbed there for pocket change). This was back when the city was dangerous and full of possibility. After the towers fell things changed. At first it was quiet and sad. But New Yorkers aren't the type to sit home and feel sorry for themselves. Shortly after the city burst with life and this sudden vibrant outburst of life, creativity and happiness drew incredible people from all over the world who once again shifted everyone's attention to New York. And these incredible people... incredible happenings... incredible everything! for that matter, then started gaining lots of people's attention and drawing people increasingly not-so-incredible. Once this started happening, almost overnight, it got to the point where Penny Arcade could refer to Manhattan as "suburbanized."Personally, it was the night I discovered that the Second Ave. Deli (an infamous New York institution) had been shut down and was going to be replaced with a Chase Bank that I resolved I had enough and needed to leave New York. It was almost officially no longer home or a refuge for the marginalized, unwanted and magnificent. This left an even bigger question, "where does one go from here?" I still have not resolved this issue (but am happily in San Francisco for the time being). And I don't think anyone has. I forget where I heard, but someone said recently that every period of time has its city. For instance, at the end of the 19th century it was Paris and the end of the 20th it was New York. The keyword there is "was." I personally think Weimar NY has picked up on this feeling and have encapsulated the "golden age between the first terror attack and the last" and will continue to carry on the torch of the grand society of wonderful weirdos and infamous outcasts so long as someone else is willing to listen.Any which way, I doubt if they will perform outside of New York City ever again, but should you happen to in the NYC, I recommend checking it out.(end rant)

Something from Nothing: Films on Design & Architecture

If you're interested in Yerba Buena Center for the Arts' TechnoCRAFT exhibition, you might also want to know about the design film series we're hosting this summer.  See below for more information. SOMETHING FROM NOTHING: FILMS ON DESIGN & ARCHITECTURE Sundays, Jul 11 thru Sep 5, 2 pm In conjunction with our TechnoCRAFT gallery exhibition, we present these eight matinee screenings, covering not only design, but architecture, motion graphics and craft. Sun, Jul 11, 2 pm Refrigerator Fetish: Vintage Industrial Design Films We kick off the series with a selection of funny, bizarre, and maybe even educational vintage product design films, from the 1920s forward. Examining the sensuality of the fridge, the rhapsody of the pencil and the mysterious polishing of unknowable objects, this promises to be a one-of-a-kind day at the movies. Presented live by film archivist Dennis Nyback. Sun, Jul 18, 2 pm Citizen Architect: Samuel Mockbee and the Spirit of the Rural Studio By Sam Wainwright Douglas Citizen Architect chronicles the work of the late activist architect Samuel Mockbee, and his radical educational program known as the Rural Studio. The program teaches students about the social responsibilities of architecture and charges them to provide original and inspirational homes and buildings (mostly from salvaged materials) in rural west Alabama, one of the poorest communities in the country (2010, 60 min, digital video). Preceded by the short Robin Hood Gardens (Or Every Brutalist Structure For Itself) by Martin Ginestie (2010, 17 min, digital video) Sun, Jul 25, 2 pm wow+flutter Assembled by onedotzero, the London-based cutting-edge new media group, this compilation program showcases the most progressive and unpredictable work in motion graphics and short-form media. Fresh talent and celebrated masters alike strive to expand, blur and explode traditional notions of what future moving images could be as a playground for creative expression. (2009, 70 min, digital video) Sun, Aug 1, 2 pm The Greening of Southie By Ian Cheney This incisive new documentary is set in the traditionally Irish-American working-class neighborhood of South Boston, where a new kind of building is taking shape. From wheatboard cabinetry to recycled steel, bamboo flooring to dual-flush toilets, the Macallen building is a leader in the emerging field of environmentally friendly design. But Boston's steel-toed union workers aren't sure they like it. And when things start to go wrong, the young development team gets a little more than they bargained for. A film about building the city of tomorrow…today. (2008, 72 min, digital video) Sun, Aug 15, 2 pm Infinite Space: The Architecture of John Lautner By Murray Grigor John Lautner was the Southern California architect. Even if his name isn’t familiar, you have likely seen pictures of some of his most famous works, such as the space-age “Chemosphere,” the octagonal house on a hill, which has become a Los Angeles landmark. Lautner believed that the purpose of architecture is to create timeless, free, joyous spaces for all activities in life. Infinite Space traces the lifelong quest of a man to create “architecture that has no beginning and no end.” (2009, 90 min, digital video) Sun, Aug 22, 2 pm Rem Koolhaas: A Kind of Architect By Markus Heidingsfelder and Min Tesch Rarely has an architect caused as much sensation outside of the architecture community as Rem Koolhaas. His outstanding creations such as the Dutch Embassy in Berlin, the Seattle Library, and the Casa da Musica concert hall in Porto are working examples of his visionary theories about architecture and urban society. An engaging portrait of the man and his work, the film takes us to the heart of his ideas. Koolhaas has stated "it's the only film about me that I have liked." (2008, 97 min, digital video) Sun, Aug 29, 2 pm The Visual Language of Herbert Matter By Reto Caduff SPECIAL SNEAK PREVIEW! A revealing look at the life story of a highly influential mid-century modern design master. Known as a quintessential designer's designer, Swiss-born Herbert Matter is largely credited with expanding the use of photography as a design tool and bringing the semantics of fine art into the realm of applied arts. Through never-before-seen footage, personal photography and stunning graphic design, the film explores the social and cultural impact of his personal visual language that influenced a generation of designers and artists. (2010, digital video) Sun, Sep 5, 2 pm Handmade Nation By Faythe Levine This charmingly low-fi film documents the contemporary crafting community. These artists, crafters and designers marry historical techniques, punk and D.I.Y ethos while being influenced by traditional handiwork, modern aesthetics, and politics. (2009, 65 min, digital video) Where: Something from Nothing: Films on Design & Architecture – 701 Mission St., San Francisco, CA 94103 – YBCA Screening Room Public Info: 415-978-2787 or ybca.org $8 regular; $6 students, seniors, teachers & YBCA members Enjoy same-day gallery admission for all YBCA presented films!

8 Reasons you'll rejoice when we hit $8 a gallon gasoline

This article in MarketWatch written by Chris Pummer mostly matches my opinions. My favorite is #2Here is the text:SAN FRANCISCO (MarketWatch) -- For one of the nastiest substances on earth, crude oil has an amazing grip on the globe. We all know the stuff's poison, yet we're as dependent on it as our air and water supplies -- which, of course, is what oil is poisoning.Shouldn't we be technologically advanced enough here in the 21st Century to quit siphoning off the pus of the Earth? Regardless whether you believe global warming is threatening the planet's future, you must admit crude is passé. Americans should be celebrating rather than shuddering over the arrival of $4-a-gallon gasoline. We lived on cheap gas too long, failed to innovate and now face the consequences of competing for a finite resource amid fast-expanding global demand.A further price rise as in Europe to $8 a gallon -- or $200 and more to fill a large SUV's tank -- would be a catalyst for economic, political and social change of profound national and global impact. We could face an economic squeeze, but it would be the pain before the gain.The U.S. economy absorbed a tripling in gas prices in the last six years without falling into recession, at least through March. Ravenous demand from China and India could see prices further double in the next few years -- and jumpstart the overdue process of weaning ourselves off fossil fuels.Consider the world of good that would come of pricing crude oil and gasoline at levels that would strain our finances as much as they're straining international relations and the planet's long-term health: 1. RIP for the internal-combustion engineThey may contain computer chips, but the power source for today's cars is little different than that which drove the first Model T 100 years ago. That we're still harnessed to this antiquated technology is testament to Big Oil's influence in Washington and success in squelching advances in fuel efficiency and alternative energy.Given our achievement in getting a giant mainframe's computing power into a handheld device in just a few decades, we should be able to do likewise with these dirty, little rolling power plants that served us well but are overdue for the scrap heap of history.2. Economic stimulusNecessity being the mother of invention, $8 gas would trigger all manner of investment sure to lead to groundbreaking advances. Job creation wouldn't be limited to research labs; it would rapidly spill over into lucrative manufacturing jobs that could help restore America's industrial base and make us a world leader in a critical realm.The most groundbreaking discoveries might still be 25 or more years off, but we won't see massive public and corporate funding of research initiatives until escalating oil costs threaten our national security and global stability -- a time that's fast approaching. 3. Wither the Middle East's cloutThis region that's contributed little to modern civilization exercises inordinate sway over the world because of its one significant contribution -- crude extraction. Aside from ensuring Israel's security, the U.S. would have virtually no strategic or business interest in this volatile, desolate region were it not for oil -- and its radical element wouldn't be able to demonize us as the exploiters of its people.In the near term, breaking our dependence on Middle Eastern oil may well require the acceptance of drilling in the Alaskan wilderness -- with the understanding that costly environmental protections could easily be built into the price of $8 gas. 4. Deflating oil potentatesOn a similar note, Venezuela's Hugo Chavez and Iran's Mahmoud Ahmadinejad recently gained a platform on the world stage because of their nations' sudden oil wealth. Without it, they would face the difficult task of building fair and just economies and societies on some other basis.How far would their message resonate -- and how long would they even stay in power -- if they were unable to buy off the temporary allegiance of their people with vast oil revenues? 5. Mass-transit developmentAnyone accustomed to taking mass transit to work knows the joy of a car-free commute. Yet there have been few major additions or improvements to our mass-transit systems in the last 30 years because cheap gas kept us in our cars. Confronted with $8 gas, millions of Americans would board buses, trains, ferries and bicycles and minimize the pollution, congestion and anxiety spawned by rush-hour traffic jams. More convenient routes and scheduling would accomplish that.6. An antidote to sprawlThe recent housing boom sparked further development of antiseptic, strip-mall communities in distant outlying areas. Making 100-mile-plus roundtrip commutes costlier will spur construction of more space-efficient housing closer to city centers, including cluster developments to accommodate the millions of baby boomers who will no longer need their big empty-nest suburban homes.Sure, there's plenty of land left to develop across our fruited plains, but building more housing around city and town centers will enhance the sense of community lacking in cookie-cutter developments slapped up in the hinterlands. 7. Restoration of financial disciplineFar too many Americans live beyond their means and nowhere is that more apparent than with our car payments. Enabled by eager lenders, many middle-income families carry two monthly payments of $400 or more on $20,000-plus vehicles that consume upwards of $15,000 of their annual take-home pay factoring in insurance, maintenance and gas.The sting of forking over $100 per fill-up would force all of us to look hard at how much of our precious income we blow on a transport vehicle that sits idle most of the time, and spur demand for the less-costly and more fuel-efficient small sedans and hatchbacks that Europeans have been driving for decades. 8. Easing global tensionsUnfortunately, we human beings aren't so far evolved that we won't resort to annihilating each other over energy resources. The existence of weapons of mass destruction aside, the present Iraq War could be the first of many sparked by competition for oil supplies.Steep prices will not only chill demand in the U.S., they will more importantly slow China and India's headlong rush to make the same mistakes we did in rapidly industrializing -- like selling $2,500 Tata cars to countless millions of Indians with little concern for the environmental consequences. If we succeed in developing viable energy alternatives, they could be a key export in helping us improve our balance of trade with consumer-goods producers. Additional considerationsWeaning ourselves off crude will hopefully be the crowning achievement that marks the progress of humankind in the 21st Century. With it may come development of oil-free products to replace the chemicals, pharmaceuticals, plastics, fertilizers and pesticides that now consume 16% of the world's crude-oil output and are likely culprits in fast-rising cancer rates.By its very definition, oil is crude. It's time we develop more refined energy sources and that will not happen without a cost-driven shift in demand.

The worst time of my life

If three years ago somebody had told me that I would be at Maker Faire, using my cyborg arms, watching Arc Attack playing the “Doctor Who” theme, and meeting Adam Savage from “Mythbusters”, I would have said that person is crazy or is mocking me. But I was there. With Instructables. It was awesome when Adam Savage, in the middle of his conference, yelled to me “Hey man! Nice borg!!”. “OH MY GOD!” I thought, “ADAM SAVAGE FROM THE MYTHBUSTERS TOLD ME I MADE A NICE BORG!!” But, beyond Adam Savage, the giant robots, the fire and electricity shows, the beautiful steampunk women, the good energy, the delicious food and the pictures with Daleks; the most beautiful, shocking, awesome and magical moment of the Maker Faire 2013 was when I had just arrived at the Autodesk booth. I saw the giant map of DIYers from around the world, and I realized my picture and profile were representing Colombia and I was one of the three leading makers of South America. I was paralyzed remembering all this journey, from being a complete loser without a future to that point in time and space when I felt absolutely happy, calm, and at peace with myself. It was worth it to keep fighting, just for that sublime moment. I felt like a Rock Star. Not because I was, but because Instructables and Autodesk made me feel like one. ……………………………………… When people ask me “Why do you love Instructables?” my answers are always the same: because the site is awesome, has amazing projects and great contests with cool prizes; because Instructables is the only one who has supported my DIY activities, especially in my country (Colombia) where science and technology aren’t priorities, and so on. But I never gave the complete answer. And now, after these fantastic five months as Artist in Residence, I want to tell the truth: I love Instructables because they were with me in the worst time of my life. ……………………………………… In 2009, I lost my job as Security Analyst in an important Colombian company. I thought I could subsist thanks to my junk projects and creating my own business, but almost nobody was interested on buying recycled crafts (besides, I wasn’t as good then as I am today.) And the only interested people wanted my works for free. It was not enough for a living, so after a few months I started looking for a job. Due to its economic situation, Colombia has high rates of unemployment and it’s very hard to find a job, and there’s no government subsidy for unemployed workers (sorry Colombia! One day, I will talk about all your beautiful and fantastic things, because you have a lot. But not today). Besides, when you are a former military officer the only civilian jobs you can apply for are in security because nobody thinks you can be creative; and if you are, nobody takes you seriously. Every two weeks I had an interview. Every interview ended with just another “we will call you.” It’s time to confess something to the world: at the same time, I was diagnosed with mild Borderline Personality Disorder and depression. It’s not something that “SHAZAM! You are nuts!”. No. I knew from years ago there was something wrong about me, but just in that moment I found out what I have. Just in case you ask: no, this condition doesn’t make me a bad employee, and I’m very competent in my work. No, I’m not some kind of evil psycho. Just a little bit creepy sometimes, but I always try my best to be a good person. And no, I’m not trying to look like a “dark and bizarre, Tim Burton style” character just because I want to look interesting. It may work for an artist or a teenager, but not for somebody trying to get a job in the security business or a stable relationship. I didn’t have any health insurance; I didn’t have money for any treatment and, in case I could afford it, there is a social stigma about persons with some kind of mental disorder, and no company would be interested in hiring a security manager with that kind of problem. So, I had to keep it to myself. I didn’t even tell it to my family. And my girlfriend broke up with me. So, my life was “complete.” I was without a job, love and almost without my sanity. Almost all of my “friends” were gone. I was drowning in debts. I didn’t have money even for basic things. I had to return to my mother’s house. I lost every goal, every dream, and every hope. The situation was so desperate that I seriously thought about giving up. But only two things stopped me from doing that. One was Carolina, the only friend I had in that moment. The other thing was Instructables. ……………………………………… I found the site several months after because I was looking for simple robots ideas. Then, I saw Instructables has contests, and I entered my first project (the “SPD Exoskeleton”) for the 2009 Halloween Contest. A lot of people made awesome comments about my project, and I received my first prize: the “Photojojo!” book and a Robot T-Shirt. “What? I just post pictures of my project on an internet site and they give me free stuff? Interesting!” Then, I made another project, the “Valentine’s RoboGrinch”. I was a finalist in the 2010 Valentine’s Day Contest. People around the world commented about my ideas, and my projects started to become popular being featured in other sites and blogs around the planet. When I got the First Prize on the Dead Computer Contest, I gave to my mother the netbook I won. It was the only present I could afford to give her in a long time. In my darkest moments, when I thought about giving up, I remembered I had some project on Instructables I didn’t finish or publish, and then I keep fighting just one or two days more, because I didn’t want to leave it uncompleted. When I finished it, I endured one week more, just for knowing if it was successful in a contest. Sometimes I won. Sometimes I lost. When I could get some money, I used it for buying tools or materials for the projects, instead of food or paying debts. Because I started to think that every project, every idea I was making, every instructable I was writing, was my little legacy to humanity. Probably one day I will die, but at least in some part of the Internet, it would be a proof that I made something good, something that could be appreciated by anybody, and my life was not in vain. And I started to win more contests. It felt good, because I thought “I’m a loser, but this loser is kicking butts!” With so many fantastic authors, the competition got tougher, so I had to improve my skills (and my English. Instructables was the only opportunity I had to improve and practice this language.) I became very good at making stuff with plastic trash and limited resources! Besides, without knowing anything about me and my personal situation, even without being on the same country, the Instructables staff and community were (and are) very special and kind with me. They always made me feel respected and loved. Instructables was the only escape I had from my reality. This site has thousands of users and still they had the time to talk to me, to care for me, to make me feel like part of a bunch of friends! They were the only people that didn’t see me or treat me like a loser or somebody who needed to be pitied. They were the only ones that made me feel I wasn’t completely alone on this planet. All of this situation lasted one year and two months. Instructables kept me fighting almost all of that time. ……………………………………… Finally, in September of 2010, I got a job. It wasn’t the best (honestly, it was horrible!), but at least I was working. Four months later, I got a better job as security manager of a business center, enough to start paying debts. On October 2010, I went to the Colombian equivalent of Comic-Con, using the Cyborg suit I built for the Instructables’ Dead Computer Contest. Thanks to this, a beautiful woman found me out of the crowd, because she loves robots. She became my biggest fan and we shared a big love. I never thought I could find a love like that. She was the girlfriend I got thanks to Instructables! She was the inspiration of my “Cyborg Heart in a Can”. And I gave it to her. And then Instructables interviewed me as Featured Author. I would be the first Colombian to be a Featured Author! That was awesome! In total, I have won twelve Instructables contests and two challenges. Thanks to Instructables, people of all the world know about my cyborgs and my Roboplanters. (The funny thing is I’m still feeling like the black sheep of the family!) ……………………………………… It was 2012. After one and a half year of relationship, my girlfriend and I broke up, for good (our respective problems were stronger than our love.) Besides, I was stuck at work and I couldn’t study something art or robotics related because the restrictive schedule of my job. So, the depression was returning… I was lying on the couch watching “Doctor Who” when a phrase get stuck in my mind: “All of time and space. Everywhere and anywhere. Every star that ever was. Where do you want to start?” And then I realized that nothing was tying me to Colombia and I could apply to the Instructables Artist in Residence Program. I wanted to know, at least for a few months, how it was to be in the most awesome company in this world. So I quit my job, I sold most of my belongings, I packed my Dremel, my trench coat and my sonic screwdriver, I said goodbye to my family and I traveled to San Francisco on February 27th of 2013. I didn’t come for the “American Dream”. I came for the “Instructables Dream”! ……………………………………… What can I say? How can I describe the most fantastic experience of my life, using just a few words? How can I summarize five months of happiness, learnings, DIY and good energy, when every day was an amazing adventure? I felt, after 35 years of life, I finally arrived in the place I belong. I met the faces behind the site I love and admire. You know who they are (sorry for breaking the magic but, please! Update the Instructables Team page! A lot of awesome people are not there!) I’m trying to not mention specific persons, because I shared awesome experiences with each one of you. Every one of you taught me something, every one of you made me feel appreciated, every one of you does a fantastic job keeping this site working. And I want nobody feels excluded of this post (Sherry always fights for sending out prizes on time, silently. Why nobody says “Thanks Sherry?”) Because Instructables is more than servers and computers and projects and internet. Instructables is the people. From the beginning, Instructables and the Autodesk Consumer Group made me feel like one of the team, like part of something bigger than myself. The Pizza Thursdays, the Marvelous Mondays, the Build Days, the Design Nights, became magical events for me. But it wasn’t only Instructables and Autodesk. This beautiful city of San Francisco taught me real lessons about tolerance, respect and being yourself. It doesn’t matter if you are radically different to the other people. Just be a nice person, do your job and respect the others, and everyone will respect you. I had never touched a CAD software, because I didn’t see any possible use for it in my life. And I thought it was something so complicated that only engineers and designers could use that kind of program. But then I went from 0 to 123D Design! I learned the basics in just two days and I fell in love with this awesome program, and it’s free! (But, seriously guys, try to fix that problem with the crashes. Everyone in the lab knew that when I screamed, it was because the program had a crash and I hadn’t saved the progress). And later, I learned how to use a 3D printer, a machine beyond my wildest dreams! I remember the infinite sadness the first time I went to the amazing Pier 9 (new installations of Instructables and the Autodesk Consumer Group) and thought I could never try that fantastic technology; and the happiness when Noah told me I could stay two months more! You have all the best freaking hi-tech tools in this freaking world, and you don’t need to be a NASA scientist or a millionaire to use them! This place is waiting for people of all the world, to come with their ideas! (It doesn’t matter how crazy they are). 3D printers, laser cutters, a water jet, a bunch of expensive machines I still don’t know the names of, an awesome test kitchen, metal and wood shops, even a sewing area! And all available for the DIY community! But, more than being on Pier 9 because the fantastic machines, I loved to stay here because Instructables.  My life has good things and bad things, successes and failures. But being part of Instructables and sharing moments with all of you has been the most memorable experience of my whole existence! ……………………………………… I want to say something to my dear friends of Instructables and Autodesk: if one day, for some inexplicable reason, you feel like your work is meaningless, you don’t like it’s Monday or simply you forgot what this is all about, just remember something: you will never know exactly how many lives Instructables has touched: how many persons found their true calling thanks to the projects, and how many persons found a hobby that makes their life happier. How many couples fell in love thanks to the delicious recipes and romantic crafts, and how many parents shared precious moments with their sons building something. But now you will always know, at least, Instructables and Autodesk saved one life. My life! ……………………………………… I wish to finish my post with some “Doctor Who” quote. I love “Doctor Who”, because is all about being awesome and optimistic and keep smiling even in the worst situations or despite you are feeling absolutely sad and alone. And the series has a lot of badass and beautiful quotes! But now, when I have to start packing my bags, when I have to return to my hometown where I have to pretend I’m a “normal” person and try to get a “normal” job again, when I have to say goodbye to my coworkers (that are at the same time most of the only real friends I have had in my life), and to the greatest organization I have had the honor of being part (where for first time in life I felt truly appreciated, respected and loved, and happy because it was Monday and I could go to work in a company that is making of this world a better place); there’s one, and only one phrase that I got stuck on my head; the last words of David Tennant as the Tenth Doctor when, standing alone after saying goodbye to his loved ones (and to the most awesome time of his life), his final moment comes: “I don’t want to go.” Mario Caicedo Langer Former Artist in Residence.
