Step 5: Toss your Throwie

The LED throwie is ready to be tossed onto a ferromagnetic surface. Practice tossing your throwies. Work on your accuracy and your own personal technique. Every throwie wont stick every time, but if you toss them gently, they will stick eventually. Get them up high and in large quantities for greatest enjoyment.
I have posted a how-to on making throwies with removable tabs where you can pull it out to turn the LED on and slide it back in to turn it bad off. It's not very hard to implement, and is quite useful for conserving battery power.<br/><br/>Here's the link: <a rel="nofollow" href="http://flickr.com/photos/everythingdigital/sets/72057594069888500/">http://flickr.com/photos/everythingdigital/sets/72057594069888500/</a><br/><br/>I'm also working on throwies that automatically turn on upon sticking to something and off when they are removed (as suggested above), and I have a few prototypes working but there are still some bugs to work out.<br/>
I have included your how-to on the <a rel="nofollow" href="http://graffitiresearchlab.com/?page_id=13">G.R.L. Throwies site</a> and in the upgrade section of the throwies instructables post. Thanks so much for the mods and looking forward to the next rev!<br/>
<p>Best quote: &quot;Throw it up high and in quantity to impress your friends and city officials.&quot;</p><p>How long do they last?</p>
Unknowable. Friends can be fickle, and city officials often disappear once installed.
<p>not sure city officials would be that impressed.</p>
<strong>INTRODUCING:</strong><br /> <br /> Throwies on steroids - <br /> The <strong>LED ULTRIE!</strong><br /> <br /> 7 LEDs arranged in a ring<br />
<p>Hello! Do you have an instructable for this one? I want to apply something similar for a soft toy I'm making, just took my first steps on LED 'wiring' yesterday and your solution seems to fit what I had in mind... without entering into Arduino land _I'm not ready yet! Thank you :)</p>
<p>so simple yet so powerful </p>
I have great news, you are today&#39;s winner of the &quot;I Made It&quot; Challenge for the month of june.

fun with LED throwies
<p>Will be amazing for party... Maybe next NYE.</p>
<p>wow that is cool ;)</p>
<p>Thanks for that, very helpful.</p>
<p>Letting the &quot;wrong&quot; LED lead touch the battery won't cause a short or <br>damage either component. LEDs are diodes and only function one way <br>round. It won't harm the LED to be reverse-biased, and indeed it's <br>designed to be connected this way in larger circuits. Lithium batteries <br>shouldn't present a disposal hazard when used in this way, as they'll be<br> fully discharged when they do reach landfill.<br><br>Better than chucking them once they've run down, why not &quot;catch&quot; them with a stick/net/string, and re-build them with a new battery?</p>
<p>is this instructable actually promoting the fabrication of &quot;throwies&quot; (as in &quot;throw-away&quot;) that consist of an LED and a Lithium Battery?<br><br>if so, I would like to line up with Shuyler, ask the author to educate himself concerning the ecological and social aspects of his proposal and publishing it on Instructables.com</p><p>I also agree that &quot;Instructables should have nothing to do with promoting it, and neither <br>should anyone else.&quot;</p>
<p>Are you serious it's a light bulb and a battery throw it around have a little fun and throw them away... What's the harm?</p>
I have little hope that facts will convince anyone who defends this practise.<br>but you asked what the harm is and I'll answer:<br><br>the harm is the battery<br><br>the hazardous ingredients of practically any type of Alkaline battery make it absolutely crucial to mindfully dispose of &mdash; not just throw them anywhere.<br>landfill should NOT be an option for disposal here.<br>closed substance cycle waste management defenitely is.<br><br>besides, throwing that kind of stuff is mere waste of material<br>(the value of wich unfortunately does not show in its price)<br>&mdash; economically and ecologically speaking.<br><br>(the fact that this type of button cell also contains lithium might also be a problem as lithium occures in such a concentration nowhere on this planet &mdash; except in man-made batteries.)<br><br>((and I would even regard it less of a problem if it WAS an actual light bulb, but it isn't. It's a piece of epoxy, sticking to a piece of acrylic, holding a little semiconductor&hellip;))
<p>Thats +1 Please don't pollute our earth for fun, that is total ignorance !!! </p>
<p>Ok, it's hazardous, but what kind of damage would throwing a few outside do? I probably sound ignorant to you, but I really just want to find out how big of a problem it is in actual numbers and what it will do to environment (I'm guessing the damage it causes is to the environment).</p>
<p>dude, this was posted 10 years ago. </p>
<p>Do you have to use the 10mm Diffused LED lights, or can you use 5mm or 3mm</p>
<p>Any LEDs will work. Just 10mm look the best.</p>
<p>Wow, hard to believe this was posted 10 years ago.</p>
<p>that is cool</p>
<p>It's great!<br>My nephew has long enjoyed doing it<br>Thank you very much for sharing. Keep going</p>
