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.

Hi, i want to make led throwies more tough. By that i mean that i want to be able to throw them on cement, without breaking at all. Iv been tryin to put them in a plastic container, but it hasnt worked. So if anyone has an idea to make them tougher, and maybe even waterproof, let me know!!!!!!!!                                                                    PLZ!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

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

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?

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?

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.

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

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!)!

Do Led Throwies really last up to 1-2 weeks?

I've been reading a post in Evil Mad Scientists about the scientifics and workings of Led Throwies and it got me thinking: If a CR2032 has a value of 250mAh (tops), and an LED consumes about 20mA, then doing the calculations (250/20) we have that the battery would run out of juice at about 12hours, then how are led throwies lasting weeks?!! Maybe I'm an idiot and this isn't the right calculation for this kind of thing. Can someone show me the light?

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.

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?
