I don’t know about you, but I rarely have money to spend on projects and whenever possible reusing and re-purposing junk is ideal.  Many of my projects contain parts I’ve purchased at local dollar stores and items found through eBay.

  • Cut the end of the stem and remove the wire.

  • Gut the Artificial Lily Flower by removing its pistil.

  • Using a 8-10″ length of Thermostat Wire that extends just beyond the end of the lily’s stem, solder a 100-330ohm resistor to flickering LED and/or later near the mini switch inside the recycled case.

Do I really need a resistor?

  • Clear LED without resistor = 30mA @ 3vDC
  • Flickering Yellow LED ~ 6mA @ 3vDC
  • salvaged 10 LED string of lights = 6mA @ 3vDC

 

  • Carefully thread the wired LED through the lily and down her stem.

  • Add a piece of heat-shrink tubing, solder jumper wires, and attach connector header.

  • Solder the Rechargeable Li-ion Coin-cell Battery charger output short jumper wires, resistor, to the mini switch and recycled case ( two “AA” batteries ).

  • Solder a simple switching diode, such as 1N4148, to the positive side.
  • Using short jumper wires, solder the Rechargeable Li-ion Coin-cell Battery charger input to the solar panel ~ 5vDC.
