How do you make a magnetic LED light?

Directions for Making LED Throwies

  1. Start by pinching the leads of your LED over a coin cell battery.
  2. Cut a small piece of electrical tape and wrap it securely around the LED leads and battery.
  3. Add a strong magnet on top of the taped battery.

Can you put LED lights on paper?

Not very likely since LED bulbs don’t get as hot as halogen or incandescent bulbs, but there’s a remote possibility a component failure results in a short circuit, which might cause a fire, but very unlikely. Would not recommend it, as it could stop it from ventilating properly.

How do you make Throwies?

To make an LED throwie, you will need tape, an LED (any size or color), a 3V lithium battery (CR2032), and a small disc magnet. LED GLOWIE: Slide the longer lead (leg) of the LED over the POSITIVE (+) side of the battery. When both leads are touching either side of the battery, the LED should immediately light up.

Can LED lights catch tissue paper on fire?

Lamps that are kept on a bedside table have an even greater risk of causing a fire, if an extremely hot incandescent light bulb should come in contact with a piece of clothing, paper or any other flammable materiel or liquid. With LED light bulbs this hazard does not exist.

How do you make wire paper lanterns?


  1. Find a mold for your lantern.
  2. Wrap the wire around the mold.
  3. Remove the wire frame from the mold.
  4. Secure each opening of your frame with wire.
  5. Form a base for the lantern.
  6. Check for stability.
  7. Cut paper panels.
  8. Glue the first panel to the wire frame.

How do you light up an LED throwie?

LED Floaties — Put throwies (minus the magnets) inside 12″ helium balloons and light up the room or the sky. LED Swimmies — Slip throwies inside plastic fish toys and light up a pond or pool party. Motion-sensing LED Throwies — Use a scrap of guitar string to make an intermittent switch so the throwie will flicker when it’s jiggled.

What is an LED throwie?

Developed by the Graffiti Research Lab a division of the Eyebeam R&D OpenLab, LED Throwies are an inexpensive way to add color to any ferromagnetic surface in your neighborhood. A Throwie consists of a lithium battery, a 10mm diffused LED and a rare-earth magnet taped together.

What are some cool hacks and mods for the LED Throwies?

NextPrev Since MAKE first published the LED Throwies how-to by Graffiti Research Lab in 2006, we’ve seen dozens of cool hacks and mods. Here are a few favorites from the MAKE blog: Programmable LED Throwies (Throwie Talkies) — Stick an Atmel ATtiny microcontroller on your throwie and the LED will flash messages in Morse code!

How long does a throwie last on a magnet?

Conclusion A throwie will shine for 1-2 weeks, depending on the weather and the LED color. To get one off a ferro-magnetic surface, don’t pull it, or it might come apart. Instead, slide the magnet sideways while lifting it with a fingernail or tool.
