solar powered throwies

In case you didn't know, a throwie is an LED with a small battery and magnet attached, that can be stuck to any metal surface. would it be practical to make a throwie with a long lasting lithium battery? or a small solar cell? just a thought

Ideas from the center of the universe #1: LED throwie machine gun

NOTE: This is so old, that I don't care anymore. If you do, be my guest to change the rules.Ideas from the center of the universe: Any challenging idea that comes into my weird, weird cranium. (I am not purposely saying that I am at the center of the universe; the title is based off of another crazy idea that I once had.)Okay, I just thought of the perfect challenge: a gun that will launch/fling LED throwies at high intervals, at least 5 per second to make it easy. The throwies can be of any size, as can the launcher. Distance limit is 50 feet horizontal.I might think of a prize later on, but I currently do not have any sponsors.Any discussion whatsoever will happen in the comments on this topic. Links to instructables are required if you have found a solution.Well, get started!YP

Need small battery powered UV emitting LED light for board game

I'm in need of a couple dozen battery powered "throwie" styled (read: super simple)  UV light emitting LED's for a board game prototype.   The devices (12 total) will be built into simple chipboard player pieces on a stand.  I'd like the entire piece (including the chipboard and stand) to be no larger that 1" x 2" x 1", but here is the catch! Each piece will start with 3 pegs placed in the stand (a la the classic board game "Life")  that keep the light on as long as there is at least 1 peg in.  Don't know if this would mean they are pressing a button or completing the circuit, but whichever is safest is ideal! I also need a 2nd version that will operate with a simple on/off switch or button that can be housed in a small piece of foam core board (.25" thick, approx. 2"x 2" piece).  I need 12 of these as well. Concept sketch attached, but more detailed information will be provided upon inquiry.  I would need them to be completed and delivered by Friday, June 8th, 2012. Thanks in advance for your help (whoever the helpful soul may be!)!

*Clears throat* Hm Hm. Dear Public Safety officer:

Dear Public Safety officer, there is a large difference between a bomb, and an LED throwie. Please stop bugging me about the red light on the electrical box, and go do something useful, like stopping a robbery. Thank you, Zem. Basically, I made an LED throwie, gave it to my friends little brother, and where does he stick it? An electrical box... Good boy. Then, not ten minutes later, a public safety officer comes over and says "Whats this? -.-" I say "Its just a light, its not doing any damage." "Okay. Just putting them up for fun are you? -.-" "Yes" "Okay. -.-" And he walks away.

Protesters in China Use LED Throwies

Pro-Tibet protesters in China used LED Throwies to illuminate a large "Free Tibet" banner in China's Olympic Park, right in front of Beijing's National Stadium.On Monday, five pro-Tibet activists unfurled a banner spelling out 'Free Tibet' in English and Chinese in blue LED 'throwie' lights in Beijing's Olympic Park tonight. The five were detained by security personnel after displaying the banner for about 20 seconds at 11:48 pm August 19th. Their whereabouts are unknown. As far as we know, James Powderly, the author of the LED Throwies Instructable is still in Chinese detainment after being picked up by Chinese authorities a few days ago for planning a LASER stenciling event.Throwies are the most viewed Instructable in history, with over half a million project views to date.Article on LED Throwies in Beijing

LED Throwies Picture

So I was in Maplin Electronics yesterday, looking or a specific transistor I needed. I was just browsing the shelves, and found so called "Goodie Bags" of LEDs. Imagine the shock then, when I saw the picture on the front. It was the same picture as is on the original LED throwie instructable! Anyone have any ideas about this? Was permission given to use it? Does it violate the terms of use of instructables?

Throwie concept

Would it be a good idea to solder one led leg to a battery, and the other to a magnet, the put a tab between the two? Has this been tried before? I want to make a few as "flares" for airsoft. Thank you for your help.

Throwies reimagined - Really I did tried :) :| :/

Seeing other forms of making interactive throwies, eg using microchips impresses me.However i think it is important that we try parts of the B.E.A.M philosophyhttp://en.wikipedia.org/wiki/BEAM_roboticsNamely keeping things simple, and avoiding the use of microprocessor.The component of a interactive throwie is that it has1. Power storage2. Trigger3. Circuit4. LED5. (optional) Power collection of radiant energy.I like to see more suggestion on ways we can address each issues.But to kick start the issue, can you see if my idea is feasible.essentially for my prototype not-yet throwie, I used a circuit from http://unconventional-airsoft.com/2003/11/16/momentary-fan-switch/#more-21to create a throwie that on sensing motion, doesn't flicker but turns on for a while.By ensuring that i use few and simple componants, i hope to keep cost per throwing down.Unfortunately my problem is that using a resistor to keep the capacitor from draining too fast from the base, actually decreases the voltage drop to an unacceptable level at the led.On my end it is unsolvable for the moment. Maybe you can work out how to make a cheap throwie, that can still do these functions or more.Any ideas how to solve this?Other Ideas for throwies1.Open and attach a switch to a barometer, to have a air presser passive trigger.2. A leave shaped pad with two conductors that do not touch, to act as rain sensors. (Resistance increase when leaf dries)3. Is sensitive to infrared radiation from side, so that the throwie is trigger-able by other activated throwies. (As well infrared devices)4. Has a short loop of coil to recharged capacitors, by outside induction.5. If activated rarely, uses a tiny single solar cell to charge capacitor.6. Has a hook to be easily collected for recycling. (Using a simple loop of wire on a pole [Like a dog catcher pole] )7. A single thermistors in series with led.8. A tricolour LED, and a Two light resistor. One LDR acts to sense if it is day an night, if night a low power light is activated. Only when an object strays near, and reflect light into another LDR, does the throwie get triggered at all.9. A throwie triggered by vibration.10. A throwie that responds to radio waves.

Remotely controlled throwies

I'd love to make some throwies that can be remotely controlled. At a minimum I want to turn them on and off, colour and brightness change would be fantastic.  What's are the options for doing this - what's the cheapest, lightest, smallest way to control them remotely? Some kind of RFID and switch? Is this going to drastically raise the price from about $1 a piece, or could it be done cheaply? How many could feasibly be controlled at once?

Suggestion: LED flyies

I've seen LED throwies, LED floaties but not LED flyies. Since I don't yet have my camera and I don't have an interest in throwies but I know a lot of people do... Anyone fancy making an LED flyies instructable? LEDs and button batteries, taped together and taped to the bottom of helium filled balloons. The balloons then tied together with cotton thread to make a mat of flying LEDs! Any takers?

LED Floaties fundraiser

I've heard so much about LED floaties,throwies,and everything else. But, I was thinking this could be used at a community cookout or something like that as a fundraiser. People buy an LED item and release it. Money could go to charity or fund. Any thoughts?

LED Throwies Kit?!?!

I was surfing some electronic websites this morning and I came across a kit that looked surprisingly like an LED Throwie. Except that this was called an LED "Art Object" Kit.LED "Art Object" KitHere is the description of the kit:Kit consisting of a small 3V BR2032 Lithium battery, a 10mm clear lens blinking red LED and a small rare earth super magnet. No soldering necessary -Just connect up the LED to the leads of the battery. Use clear tape (not included) to attach the super magnet to the battery. You are now ready to throw your miniature bright red "piece of art" onto any steel structure where it will flash for days. Complete with magnet, LED, battery and diagram.

Throwie/Blinky using LED for Solarpower or using Radiowaves

Hello,I was wondering if its possible to make a "battery-less" throwie or blinky.I know there have been some solar throwies arround, but when looking through a message-board I found two circuits that use radiowaves or photovoltaik properties of a LED.The only difference is that the "bettery-less" throwie would have to collect power untill its dark, and then feed from it.Since I am not really into all the electronics yet, I do now know how well capacitors will keep their load, and if a aditional day/night switch detector will consume much power.The LED-drives-itself circuit: LED drives itself from Mikrocontroller.net(I've read in the forums that preparing the LED with sandpaper so its diffus will make it less angle dependant to charge?)The Radiowave-Blinker circuit: Radiowave blinkerfrom the german electroniwerkstatt-Forum (Click and look at end of toppic)A simple day-charge / night-operate circuit (such as a garden solar night light)[http://solar night LED https://www.instructables.com/id/EPYWPCC3M0EVYE00UZ/ CLICK]Has anyone build something like that?

LED Throwie Bop

I've been a Masters student for the past two years and recently decided on a topic that investigates alternate/awkward styles of presenting DIY tutorials (If you're curious what this means, let me know and I'll give you a bit more information). I guess working at Make Magazine and Instructables for 6 or 7 years made an impact. For my first foray into this I decided to make a tutorial based song, and LED Throwies seemed the easiest thing to do it on. I'd love to hear what you may think, and if anyone is interested, I'd be glad to show you what other methods I come up with as I think of them. You can listen to the song here, and if you're curious about how we came up with that, you can check out the making of in the previous podcast. Lyrics: Hey Ho, Let’s Throw x4 First you grab your batteries Then you grab your LEDs Magnet, Tape, Accessories The LED Bop The anode to the plus bit The cathode on the alternate Then tape it to your magnet The LED Bop Hey Ho, Let’s Throw Toss them in the air now Where they land, I don’t know They’re all charged up and ready to throw Repeat x3

Nuclear powered throwies keep Boston on terror alert for sixth decade, seventh on horizon.

OK, so it's an attention-grabbing headline, but the potential is now there.Radio-isotope batteries (the same things that have kept the Voyager craft alive since the seventies) can hold a million times as much charge as a standard chemical bettery the same size.As radioactive isotopes decay, the charged particles they emit are trapped by semiconductors and turned into useful current.  Past versions of the battery have used solid semiconductors, which suffer damage from the radiation, so need to be large to survive as long as the isotope.  Now, a team from the University of Missouri has developed a liquid semiconductor that can survive the damage whilst having much less bulk, and have put together batteries the size of a coin.  They are working on much smaller versions, capable of powering micro- or nano-scale devices.Just imagine the possibilities...University of Missouri - Nuclear battery linksBBC Story

Cheap LED, Batteries and magnets

Hi, I want to make a whole bunch of lowtec-throwies, just a simple version to decorate and take pictures here, not the ultra-bright highly magnetic kind.The problem right now is that 200-300 throwies with cheap LEDs would cost more then $100 if I get the parts at our local electronic store (and that without magnets)."besthongkong" has 1000 LEDs for $10+$10S/H (=2 cents each) but does anyone know another cheap source with a larger variety and colors of low cost LEDs, maybee even low current ones? Maybee even in Europe?Second thing: Batteries. Lithium cells are rather pricey at that quantity, and cheap button cells seem to do the job.I had a couple of 1,6v LEDs on two button cells with diods I had lying arround (voltage drop). It was not very bright but they still glowed a week later.I had a cheap 12 pack assorted buttoncell blister, and I foundhttp://www.dealextreme.com/details.dx/sku.61But they seem to have even worse quality ;-) Idd probably have to use three or more and still throw some out.I remember an experiment using wire and coins, lemon juice or vinigar, which made a LED glow dimly. Any Idea how long before this DIY-Batery runs out?Third thing: Magnets!DX has 20 for less then $2. but I guess at that weight I could just magnatize some scrap metal and cut it into pieces. Thats about a third of the costs even with all the shipping :-)Anyone here that knows any other good site for LEDs, magnets and such that ship to europe?

US Distributor of HB Electronic's LEDs - www.Buy-LEDs-Online.com

I just completed an order for a couple hundred LEDs and batteries that Instructables will be using at SXSW next week to make LED Floaties at PopSci's SXSW afterparty. I ordered them from Buy-LEDs-Online, a US distributor for the well written about HB Electronics. HB Electronics is the recommended vendor of LEDs for LED Throwies and LED Floaties. They ship direct from China, but unfortunately they were out of stock on their throwie packs. Buy-LEDs-Online helped me out by providing everything we needed with great phone and email support and super fast shipping. Robert from Buy-LEDs-Online was not only very helpful, but said that he knew of Instructables and that he uses the site to determine what products he should carry. So, if you're looking for LEDs for your next project, I highly recommend getting them from Buy-LEDs-Online.This is not an advertisement and my opinions are unsolicited. These are the words of [www.instructables.com/member/noahw noahw], LED purchaser, Instructables Content Producer, and debutante extraordinair.

Friend of Instructables and Friend of Humanity Held in China

Long-time friend of Instructables James Powderly of GRL, FFFFFAT LAB and Throwies fame is currently reported to be held by the Chinese Government for over 24 hours without further word for planning a pro-Tibet LASER Tag event in Beijing. "James is proud to have been kicked out of the Synthetic Times new media art exhibition in Beijing because he wouldn't censor his little art project. James wonders why organizations like the MoMA, Parsons, Eyebeam, Ars Electronica and many other arts and cultural institutions around the world who claim to support free speech and expression would participate in a show like this. But they did! It was after being kicked to the curb by the show's curator that James connected with Students for a Free Tibet and decided he would go to China anyway and do what he though was right in support of Tibet, Taiwan, free speech and the people of China. James lives, if indeed he is alive, in the County of Kings, Brooklyn, and teaches at the Communication Design and Technology program at Parsons the New School for Design. I am James Powderly and I approve of this message."We wish the best to him and his family.This via Boing Boing.

Roll over ads with sound

The "roll over "ads that have talking messages and sound are most annoying. So bad, they will cover an area I want to click. Some of them won't close until they have there say.  I was so turned off that I closed the page and left. I hope instructables will see the negative effect these have and put an end to it. Two of them popped up at the "6 cent throwie" and at the "contact us" page. I believe one was titled Hangover Days and some other concerning Microsoft.

Adult Swim and Interference Inc - This NOT the work of the GRL

An advertising agency managed to shut Boston down with a guerrilla marketing campaign gone bad. Inspired by the GRL (the people behind LED Throwies), Interference, Inc, whose website appears to be blank right now, created some LED-based graffiti to promote a cartoon. Our friends at the GRL were not impressed, and posted a response here.Like a dog in heat, a producer/reporter from Inside Edition tracked me down earlier today hoping to find, and I quote, "a techie willing to explain these light-bulbs attached to magnets that are all over Boston." I tried to explain that the GRL and LED Throwies had nothing to do with it, but perhaps subtlety is lost when you're hot on the trail of a story. Carl, if you're out there, these are the links you weren't interested in getting from me. The people who actually are behind this posted the video below (which was removed by the original author, but reposted by the GRL). I grabbed it from here.There are lots of very interesting questions around this whole issue: When does art become advertising; how can we as "techies" educate those around us as to what's a bomb and what's art; and who is responsible for actions like these that shut down a city? The artists? The corporation that put them up to it? The government for making itself and the public so paranoid? In any case, join me in watching how this unfolds.

LEDs for dummies

I have been looking at some of the LED projects here and they look great, I would like to try out a few of them with my 12 year old. But never having worked with electronics before we are both total beginners. So I haev two (for now!) questions, what projects are suitable for begineers (the LED throwies look easy, but what else?) And people keep saying to buy them online, or ebay, but there are LOTS of different kinds, so can someone kindly give me a basic shopping list a few types that would be suitable for a few basic projects. Thanks

LED batteries voltages and resistors?

Hi, I'm planning on making some throwies... I see that you can use a 10mm LED with a 3v watch battery without any resistors. Can I use a 5mm 1.7v LED with a 3v watch battery as well? Or could I hook 2 5mm 1.7v LED's to one 3v watch battery without using resistors? Is there any other watch type batteries that work well with a 5mm 1.7v LED? I don't want to connect them to AAA batteries lol... could hurt someone when throwing those. The reason I ask is because the 5mm LED's are like 1/10 the cost of 10mm LEDs. Thanks

Build Night LEDs at Numurkah Secondary College

Numurkah Secondary College hosted is first ever Instructables build Night, featuring LEDs. A fun night was had by all, making different projects, playing with the laser cutter, 3d printer, vinyl cutter and attaching LEDs to everything including small children. Throwies were a very popular project, also a couple of sound modulators were build on the night, and a chaser that was designed for florescent tubes was converted to LEDs.  The monkey Light, and blinking faux neon signs were a hit will the little kids, and big kids alike. Thanks to Instructables for supplying the LEDs and batterys and also to Instructables member 'motoring'  for organising the night.

anybody willing to make an instructable for this? (wireless power schematic)

So, I absolutely love the "Wireless LED Throwie" project here: http://mindtomachine.blogspot.com/search/label/wireless%20power videos: https://www.youtube.com/watch?v=p0-_ZX2oMyI https://www.youtube.com/watch?v=ieGOd2F_8MQ But there's some conflicting info (10uf capacitor in the parts list but 1uf on the pcb template, and pcb doesn't match schematic or what's shown in the video), and some info is just never given (transmitter coil diameter and number of turns). I want something like this where the transmitting coil is much larger than the receiving coils and can hold multiple, rather than the sizes being matched.  I'm hoping somebody a bit more advanced than I am would be willing to tackle this first and take notes.

a DIY optical port

I have been intrested in optical computer for a while but found them rather expensive to build so I tried to look for cheaper ways to build some key features like the gates. The basic idea is to use solar cells that power a led. For and OR-Port you use solarcells where it is enough that one of the side gets light to make the led burn. To make and AND-port, you can put a resitor in between so that it really needs the power form both channel sot make a led burn. For a NOT-port you put an invertor in, so that when it burns it gives no signal, and wheren it does not receive light it burns this because of a battery it caries. A NOT-port is almost like a led-throwie.I do hav emore but wanted to know if this would be a good place or not, or if someones intrested in hearing on how to build a full optical computer, still basic, but almost completly optical, or if it would be better to post this on the microprocessor group at the opencourseware of the MIT ?

Who's in Las Vegas?

Eric and I will be running an Instructables play area at Autodesk University in Las Vegas this year. If you live nearby, or will be in Vegas between November 28-December 1 2011 (the week after Thanksgiving), comment here or send me a PM!  We'd like to invite you to stop by, show off what you're working on, and play with some of our toys.  Why will this be awesome?  The folks from Epilog will be laser-engraving your gear, we'll be making LED Throwies and marshmallow guns (with a shooting gallery!), Lion Brand is sending yarn, and we'll be assembling 3D cardboard models like this.  There may also be a giant inflatable Instructables robot. So! Do you live in or near Vegas?  Are you visiting, or attending AU?  Let me know, and stop by our booth at The Venetian. It's free to visit our space, as it's outside the conference proper. SUPER-SEEKRIT BONUS: if you stop by and identify yourself as an Instructables member, you'll get one of our awesome new limited-edition Robot lapel pins.

im new. questions about led and a 9v.

Circuit boardim trying to create a circuit board with leds on it that spells out my handle. i was thinking of using it as a throwie or like a calling card. im totally new to this so i didnt want to try and use a printed circuit board since i have never done anything like this before. i used a circuit board i bought at radio shack. im building it with standard super bright 5mm leds that are about 2.1 v and im not sure how many Ma. i assume 25 Ma. no matter how i plug these numbers into my formula (source volts - led volts / Ma) the leds always seem to run hot. i cant figure out what resistor to use. the power supply is a 9v battery. i also would like to know how to string about 30 of them together off one 9v. i know its alot but can anyone give me some advice or help me out?

alkaline batteries connected in parallel, quick question

Okay, doing some throwie-inspired LED "artwork" and I'm using alkaline AA batteries instead of the CR2302s or similar smaller cells to get way more mAh and extend the life of my display. I've got all the proper resistors and AAs connected in series to get the right voltage, etc... but I want to rig up a second set of AAs in parallel. I've found a few posts and websites talking mainly about lithium cells and/or specifically rechargeables connected in parallel, but nothing on alkalines. I know to make sure they're of the same make, type, not to mix new and old (aka the same mA)... but will leaving parallel alkaline batteries connected until they are all used up cause any problems, possible fires, leakage, plagues, end of the world? I've found one web page talking about if one of the cells in parallel was lower in mA (or maybe only if it's faulty?) it could drain faster and possibly short, draining the energy from the other cells, possibly causing a fire hazard... Not good for my artwork or the places it will be displayed. Any thoughts would be greatly appreciated. Thanks for the help!

Toggles, LEDs, and Ultimate Frisbee

So here is my challenge. I play an ultimate frisbee pickup game every week (Tuesday at the Harvard commons in Cambridge, MA, at 7PM stop by and play!). We have a great LED frisbee that extends the games into the night, but once it gets really dark telling teams apart becomes challenging. I hit upon the idea of making LED 'throwies' for one's body. Take a little 3v watch battery, tape the leads of the LED on with some electrical tape, and then use a safety pin clip it onto to clothing, and blamo!, you have an LED pin that makes playing ultimate frisbee in the dark surprisingly easy, fun, and colorful. There are some problems with this. First, it takes a little time to wire up the LEDs. It is a fun group activity to start with, but this is a pickup game so people wander in all of the time to play, and each time this happens someone has to run off to make some more LED pins. It would be awesome if I just had a bag of them ready to go. Second, I have to pull the pins apart after each game. Third, my red and yellow LEDs (blue and green are fine) really need a resistor as they tend to go dull. Finally, I would really like to make these guys a little more robust by fixing the leads on more solidly. So, with that said, here are some things I could use some ideas on. 1) Cheap toggles. I needs them. I would be willing to toss a few more dollars at these pins if I didn't have to tear them apart each time. Toggle switches would mean I wouldn't have to tear out the battery each time. I am having a really hard time finding cheap small toggles on the inter-tubes. Does anyone know of some good places to look? There is also the added challenge of finding a way to attach the toggle in a mildly robust manner. 2) I am looking to rig these pins up into something a little more sturdy. I was pondering soldering the LEDs to the 3v coin batteries I am using and then super gluing the solder. Is this workable, or should I just break down and buy some battery holders? If battery holders are the answer, again, does anyone know of a cheap place to look? Finally, does anyone have any other interesting suggestions? I am willing to drop a little money into the project, but I really don't want to be spending 5 dollars per pin. In my ideal world my final product would look like an LED, a battery, and switch mounted on a safety pin in such a manner that if someone sticks it to their shirt and rolls into the ground it doesn't break. Getting all of those things to come together in an even vaguely cost effective manner is proving to be a bit of a challenge. Any ideas would be great!
