These glowsticks can be used anywhere you want to glow and in any colour you want. I invented them when trying to make my laptop stand more attractive. But you can use them as throwies by attaching a little magnet on it. I explained the instruction before on my Laminate Parque Laptop Stand project but this was before Let It Glow contest :D so i want to enter the contest with my LED Glowstick project. Same photos, but a separate project.
Step 1: Parts & Preparation
Step 2: Start to Make a GLOWSTICK
I inserted two LEDs at the ends of the straws and used heatshrink to make it tight.
You can use just one straw to make a LED glowstick throwie. On my project, power wasn't a problem but if u want to make a portable project with 3 volt batteries like CR2032 u must insert the LED just one end of the straw and close the other and with a tape or something. Or u can insert a burned (dead) LED as a mirror for more light effect.
