Chibitronics White LED Circuit Stickers - Megapack, 30 white LED circuit stickers

Works well

I wanted a tiny light for my greeting card making and these fit the bill. You couldn't find a tinier light and the instructions give you plenty of info for easy installation. And you get ton of them in an order, well worth the money.

I bought some double sided copper tape and a boat load of batteries and set off to my craft room to make cards. It has taken me a while to figure out how to lay out all the elements in the confines of a card but I'm getting better. These little stickers work great! I have had to pull them off multiple times when I messed up the tape layout and they have stuck back down just fine. In the picture of the stickers it looks like there are 10 stickers so I thought the rest were behind. It turns out that what looks like one piece contains 3 tiny stickers so you are seeing all 30 stickers in the picture. I didn't realize that at first because I had never used them before. I would recommend these sticker lights and I look forward to showing my grandson how to make circuits and play with them too.

I used Chibitronics LED Circuit Stickers in an art class to make light-up greeting cards. I had previously done the same class with Surface Mount LEDs. Surface Mount LEDS are much smaller--about the size of a grain of rice--making them very difficult to work with. Chibitronics larger overall size and adhesive backing make them easier to work with. Chibitronics triangular shape also makes identifying polarity very easy. Chibitronics have built in resistors which allows all color lights to work with every other color light. This is not true for Surface Mount LEDs. Surface Mount LEDS are much cheaper- about ten for a dollar compared to a dollar each for Chibitronics. Next time I work with seniors or kids I'm going to spring for the Chibitronics.

I found these too hard to get them to consistently light up when the circuit is closed. Sometimes they did, but sometimes they didn't.
