The LED Throwie

"Led Throwies (An LED throwie is a small LED attached to a coin battery and a rare earth magnet , used for the purpose of creating non-destructive graffiti and light displays.) were devised by James Powderly and Evan Roth working together at the Graffiti Research Lab during a fellowship at Eyebeam OpenLab in 2006. The technology, like everything from the OpenLab, is open source and in the public domain. LED Throwies were designed as a new kind of graffiti art to be used on ferromagnetic surfaces like steel. Part of GRL's original campaign involved distributing throwies to a group of people, who were then encouraged to throw them onto a metal sculpture called Alamo, located at Astor Place, Manhattan, New York City."

SANAA, Yemen (AP) &mdash; Yemen's autocratic <a href="http://www.christianlouboutinredbottoms.com/" rel="nofollow" title="Christian Louboutin"><strong>Christian Louboutin</strong></a> leader agreed Wednesday to step down after months of demonstrations against his 33-year rule,pleasing the U.S. and its Gulf allies who feared that collapsing security in the impoverished nation was allowing an active al-Qaida franchise to step up operations.<a href="http://www.christianlouboutinredbottoms.com/" rel="nofollow" title="Christian Louboutin Sale"><strong>Christian Louboutin Sale</strong></a> President Ali Abdullah Saleh is the fourth leader to lose power <a href="http://www.christianlouboutinredbottoms.com/" rel="nofollow" title="Christian Louboutin Shoes"><strong>Christian Louboutin Shoes</strong></a> in the wave of Arab Spring uprisings this year, following longtime dictators in Tunisia, Egypt and Libya.But the deal ushering Saleh from power grants him immunity from prosecution and doesn't explicitly ban him from the country's political life &mdash; <a href="http://www.christianlouboutinredbottoms.com/" rel="nofollow" title="Christian Louboutin Outlet"><strong>Christian Louboutin Outlet</strong></a> raising doubts that it will address Yemen's many problems.<a href="http://www.christianlouboutinredbottoms.com/" rel="nofollow" title="Cheap Christian Louboutin"><strong>Cheap Christian Louboutin</strong></a> The deal opens the way to what will likely be a messy power struggle.<a href="http://www.christianlouboutinredbottoms.com/" rel="nofollow" title="Christian Louboutin Online"><strong>Christian Louboutin Online</strong></a> Among those possibly vying for power are Saleh's son and nephew, who command the country's best-equipped military units; powerful tribal leaders; and the commander of a renegade battalion.Saleh had stubbornly clung to power despite nearly 10 months of huge <a href="http://www.christianlouboutinredbottoms.com/" rel="nofollow" title="Christian Louboutin Cheap"><strong>Christian Louboutin Cheap</strong></a> street protests in which hundreds of people were killed by his security forces. At one point, Saleh's palace mosque was bombed and he was treated in Saudi Arabia for severe burns. When he finally signed the agreement to step down, he did so in the Saudi capital of Riyadh after most of his allies had abandoned him and joined the opposition.Seated beside Saudi King Abdullah and dressed smartly in a dark business suit with a matching striped tie and handkerchief, <a href="http://www.christianlouboutinredbottoms.com/" rel="nofollow" title="Christian Louboutin UK"><strong>Christian Louboutin UK</strong></a> Saleh smiled as he signed the U.S.-backed deal hammered out by his powerful Gulf Arab neighbors to transfer power within 30 days to his vice president, Abed Rabbo Mansour Hadi.<br><br><a href="http://www.christianlouboutinredbottoms.com/" rel="nofollow" title="Christian Louboutin Discount"><strong>Christian Louboutin Discount</strong></a><br><a href="http://www.christianlouboutinredbottoms.com/christian-louboutin-collection-c-18.html" rel="nofollow" title="Christian Louboutin Replica"><strong>Christian Louboutin Replica</strong></a><br><a href="http://www.christianlouboutinredbottoms.com/christian-louboutin-collection-c-18.html" rel="nofollow" title="Replica Christian Louboutin"><strong>Replica Christian Louboutin</strong></a><br><a href="http://www.christianlouboutinredbottoms.com/christian-louboutin-collection-c-18.html" rel="nofollow" title="Christian Louboutin Knockoffs"><strong>Christian Louboutin Knockoffs</strong></a><br><a href="http://www.christianlouboutinredbottoms.com/christian-louboutin-sneakers-c-11.html" rel="nofollow" title="Christian Louboutin Sneakers"><strong>Christian Louboutin Sneakers</strong></a><br><a href="http://www.christianlouboutinredbottoms.com/christian-louboutin-boots-c-5.html" rel="nofollow" title="Christian Louboutin Boots"><strong>Christian Louboutin Boots</strong></a><br><a href="http://www.christianlouboutinredbottoms.com/new-christian-louboutin-c-20.html" rel="nofollow" title="Red Bottoms"><strong>Red Bottoms</strong></a><br><a href="http://www.christianlouboutinredbottoms.com/new-christian-louboutin-c-20.html" rel="nofollow" title="Red Bottoms Shoes"><strong>Red Bottoms Shoes</strong></a><br><br> He then clapped his hands a few times.&quot;The signature is not what is important,&quot; Saleh said after signing the agreement. &quot;What is important is good intentions and dedication to serious, loyal work at true participation to rebuild what has been destroyed by the crisis <a href="http://www.christianlouboutinredbottoms.com/" rel="nofollow" title="Christian Louboutin On Sale"><strong>Christian Louboutin On Sale</strong></a> during the last 10 months.&quot;Saleh had agreed to sign the deal three times before, only to back away at the last minute.The power transfer will be followed by presidential elections within 90 days.

Mitt Romney presented himself at Wednesday night's debate as &quot;a man of <a href="http://www.coachfactoryonlinesale.com/" title="Coach Outlet"><strong>Coach Outlet</strong></a> steadiness and constancy.&quot;But one response the former Massachusetts governor gave, on a crucial issue <a href="http://www.coachfactoryonlinesale.com/" title="Coach Outlet Store"><strong>Coach Outlet Store</strong></a> of economic policy, might not help bolster that image.Asked at the outset of the <a href="http://www.coachfactoryonlinesale.com/" title="Coach Outlet Factory"><strong>Coach Outlet Factory</strong></a> debate whether he would allow Italy to fail (meaning he would allow its government to <a href="http://www.coachfactoryonlinesale.com/" title="Coach Factory"><strong>Coach Factory</strong></a> default on its debt) and whether the United States has a stake in the ongoing eurozone crisis, Romney <a href="http://www.coachfactoryonlinesale.com/" title="Coach Outlet Online"><strong>Coach Outlet Online</strong></a> said he would take a hands-off approach. &quot;Europe is able to take care of their own <a href="http://www.coachfactoryonlinesale.com/" title="Coach Outlet Stores"><strong>Coach Outlet Stores</strong></a> problems,&quot; he said.Romney added that he opposed bailing out banks on either side of the <a href="http://www.coachfactoryonlinesale.com/" title="Coach"><strong>Coach</strong></a> Atlantic. &quot;There will be some who say here that banks in the U.S. that have Italian debt, that we ought to help <a href="http://www.coachfactoryonlinesale.com/" title="Coach Factory Outlet Online"><strong>Coach Factory Outlet Online</strong></a> those, as well,&quot; he said. <br><br><a href="http://www.coachfactoryonlinesale.com/" title="Cheap Coach"><strong>Cheap Coach</strong></a><br><a href="http://www.coachfactoryonlinesale.com/" title="Discount Coach"><strong>Discount Coach</strong></a><br><a href="http://www.coachfactoryonlinesale.com/coach-classic-bags-c-2.html" title="Coach Bags"><strong>Coach Bags</strong></a><br><a href="http://www.coachfactoryonlinesale.com/coach-crossbody-c-3.html" title="Coach Crossbody"><strong>Coach Crossbody</strong></a><br><a href="http://www.coachfactoryonlinesale.com/coach-kristin-bags-c-5.html" title="Coach Kristin Bags"><strong>Coach Kristin Bags</strong></a><br><a href="http://www.coachfactoryonlinesale.com/coach-madison-bags-c-6.html" title="Coach Madison Bags"><strong>Coach Madison Bags</strong></a><br><a href="http://www.coachfactoryonlinesale.com/coach-op-art-bags-c-7.html" title="Coach OP Art Bags"><strong>Coach OP Art Bags</strong></a><br><a href="http://www.coachfactoryonlinesale.com/coach-poppy-bags-c-8.html" title="Coach Poppy Bags"><strong>Coach Poppy Bags</strong></a><br><a href="http://www.coachfactoryonlinesale.com/coach-purses-outlet-c-9.html" title="Coach Purses Outlet"><strong>Coach Purses Outlet</strong></a><br><a href="http://www.coachfactoryonlinesale.com/coach-satchels-sale-c-10.html" title="Coach Satchels Sale"><strong>Coach Satchels Sale</strong></a><br><a href="http://www.coachfactoryonlinesale.com/coach-tote-handbags-c-11.html" title="Coach Tote Handbags"><strong>Coach Tote Handbags</strong></a><br><a href="http://www.coachfactoryonlinesale.com/" title="http://www.coachfactoryonlinesale.com/"><strong>http://www.coachfactoryonlinesale.com/</strong></a><br><br><br>&quot;My view is no, no, no. We <a href="http://www.coachfactoryonlinesale.com/" title="Coach Factory Online"><strong>Coach Factory Online</strong></a> do not need to step in to bail out banks either in Europe or banks here in the U.S. that may have Italian debt.&quot;Sounds clear enough. But asked a related, though different, question at a debate last month -- what he'd do if a Eurozone crisis put the global financial system on the brink of <a href="http://www.coachfactoryonlinesale.com/" title="Coach Factory Outlet"><strong>Coach Factory Outlet</strong></a> collapse -- Romney, in contrast with his rivals, sounded much more open to getting involved.&quot;Clearly, if you <a href="http://www.coachfactoryonlinesale.com/" title="Coach Handbags"><strong>Coach Handbags</strong></a> think the entire financial system is going to collapse, you take action to keep that from happening,&quot; he <a href="http://www.coachfactoryonlinesale.com/" title="Coach Purse"><strong>Coach Purse</strong></a> said. &quot;In the case of Europe right now, they are looking at what's happening with Greece. Are they going to <a href="http://www.coachfactoryonlinesale.com/" title="Coach Online"><strong>Coach Online</strong></a> default on their debt, are they not? That's a decision which I would like to have input on if I were president of the United States and try and prevent the kind of contagion that would affect the U.S. banking system and put us at risk.&quot; He added: &quot;I'm not interested in bailing out individual institutions that have wealthy people that want to make sure that their shares are worth something. I am interested in making sure that we preserve our financial system, our currency, the banks across the entire country.&quot; How it would be possible to preserve &quot;banks across the entire country&quot; without aiding individual banks was left unsaid.Given public opposition to bailouts, it's perhaps not surprising that Romney might want to move away from his apparent earlier openness to taking action.
I don't really like the message on there..... but as an important enlightenment leader said, "I do not agree with what you say, but I will defend to the death your right to say it!" 20 points to whoever can guess who said it.
Zapp Branagan
actually, my history teacher said it.
Zapp Branagan is your History Teacher
well then zapp branagan's history teacher is peter griffin.
I was going to say something here but I won't. Everyone to his own.
2008. so long ago... I now know that posting about politics on the internet is like putting your arm into a starving lion's cage after covering it in meat and doing gazelle calls.... someone may come take your arm for it if you're not careful.
I believe you did. Who else would be posting from your profile. Duh.
technically, I typed it. win.
Evelyn Beatrice Hall ackshully said it first~ I win !
That quote is often misattributed to Voltair. If it's him you were referring to, I'm right and I get 20 points. If I'm wrong, please enlighten me to who you were quoting.
yes, it is Voltaire. and why do you say missattributed? I I'm ill informed, I'd like to know.
I thought it was Voltair too, but then I saw this:<br/><a rel="nofollow" href="http://answers.yahoo.com/question/index?qid=20080925055220AAPcWVe">http://answers.yahoo.com/question/index?qid=20080925055220AAPcWVe</a><br/>
Nice, accurate and to the point. I think the representation of these LED are actually superb one. This is my first visit to your site and I want to take this moment to say that I really love this blog. It has been a good resource of information for me in my research on circuits of LED.

its tempting to make a response....with Bush or McCain...........
Yea that sounds like a simpler/cheaper way
does it HAVE to say OBAMA?!?<br />
at least it doesnt say &quot;OSAMA&quot;
How about &quot;GW BUSH&quot; wouldn't that be just as ridiculous?
Try not to make an Instructable with political stuff in it. You have every right to do so, but some people will criticize you for it. I am not criticizing you, but there are some people who will not like you for your political beliefs. They are called "radicals," and both major U.S. political parties have them. Sorry for the gloomy comment. Otherwise, cool Instructable! :)
I agree look how much effort is being put into politics instead of this cool and nifty idea.
cool AND nifty? two for one :P
LOL, they are called "patriots" because they know what is really going on behind this steel curtain knows as US politics. :P
oh come on unless you ARE behind the "steel curtain" no ne really know what is "going on " politics are an unwinnable war! happiness nd long life to all those laidback!! cheers!
... radicals kill people for political/religious reasons criticism is human...
So Jesus killed people? Last I checked, he was pretty radical...
win :)
Um, LED Throwies are a form of graffiti which has stemmed many different forms of street art that deal with political views. In fact graffiti itself is now used to spread political messages. That's like saying I made and instructable about Wheatpasting and people don't expect me to put some kind of propaganda in the instructable.
Got it... Thanks... I know, I think a debate was on and I was looking at the LED throwing GRL post at the same time. Thanks :)
I&nbsp;like this instrucable too...<br /> <br /> Can we &quot;throwie&quot; him out of office?&nbsp;
Correction... &quot;<em>instructable</em>&quot;.
hey great work, how long does the batterie last?<br /> <br />
I love this! great work... yay for obama!
Just had a brain-blast. Tape is handy but will eventually fall off. Instead of taping the leads of the LED to the battery, you could use a "conductive when cured" epoxy. You can find some on ebay. 20 points to whoever can guess where "brain-blast" is from.
OOH! OOH! JIMMY NEUTRON!<br/><br/>(I feel like a failure for even knowing that.)<br/><br/><sup>(and sorry for shouting.)</sup><br/>
Haha nice
+20 points to you
Maybe instead of a sheet of plastic one could recycle a plastic bottle?
That sounds like a much cheaper way! Just cut the ends off a plastic bottle... of course, it needs to be one that has a paper or plastic wrapper on the outside that can be removed, otherwise your message will be obfuscated by the printing on the bottle.
actualy, why cut the ends off... just need one end to feed the message into... and depending on the size of the battery, it may fit into the smaller hole on the side. Perhaps just glue the magnet to the outside instead... I like this idea... just make sure you rinse out the bottle, and wait for it to dry... nobody likes a wet message!
one problem i see ~~OSAMA~~ OBAMA IS BAD FOR THE ECONOMY
yeah, 'cause tax cuts and big spending was helping us dig out of the hole we were in. i'm not all for obama, but he's a better fit than the connecticut cowboy.
he's never led anything!
haha, i get it, "he's never LED anything"
is that why he's bad for the economy, or are we just gonna bounce from accusation to accusation? i ask because i wanna know whether to stay involved in this conversation.
