Introduction: LED Flowers
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
- 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
- socket terminal strip
- bell wire
- green insulating tape
- heat shrink tube
- white translucent paper
- green translucent paper
Step 2: Solder the Circuit
Solder the circuit following the diagram to a perfboard. Instead of soldering the LEDs, use parts of the socket terminal strip where you can stick the flowers later.
Step 3: Make the Flowers
Cut two pieces of wire (10 inches long). Solder the LED to one end of the wire. Isolate the contacts with shrinking tube. Twist the wire.
Step 4: Make the Flowers (2)
Now wrap the wire with green insulating tape to get a nice stalk.
Step 5: Make the Blossoms
Step 6: Make the Flowers (3)
Cut out two leaves of green translucent paper and tape it to the stalk.
Now make 5 more paper LED flowers...
Stick the flowers to your circuit. Insert it in a vase, connect the battery and you are done. Give the LED flowers to your loved one and enjoy the fading blossoms...
We have a be nice policy.
