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
