Picture of LED Flowers
What would be a better present for your valentine than a bunch of flowers? The flowers I made glow nice in the dark and dont fade away. They dont need water, but electric energy to live. Here is how to make a bunch of LED flowers for your valentine.



I lend the circuit from the "Conrad Advent Calendar 2012". German users might know these electronic advent calendars that provide an experiment a day in the advent time. If you spent your advent time with the "Conrad Calendar", you can already go and make the circuit of Day 24. If not, you can buy them in every electronic component store.

Step 1: Parts and Material

For the electronic circuit you need:
  • 6 LEDs different colors
  • CMOS IC 4007
  • 3 capacitors, the original circuit uses 100nF caps, but I used 1µF capacitors to make the fading slower
  • resistors: 3x 10M, 6x 4,7k
  • 9 V battery and battery clip
  • perfboard
  • socket terminal strip
  • wire
For the flowers you need:
  • bell wire
  • green insulating tape
  • heat shrink tube
  • white translucent paper
  • green translucent paper

What kind of translucent paper did you use? From the images, it kinda looks like the paper used to stuff gift bags.

I used the paper we use to cover our breakfast (bread) in germany, but you can choose what you like. Also printed paper may look fine if it has a nice print....

Ich bin gespannt!Danke.Last year I made a bunch of 3 origami tulips with flashing LEDs inside. No chip at all. LEDs are soldered in parallel. Drinking straws(green) were used as stalks. I must say your LED Blumen look much more impressive.
