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.

Discount hackables!!

Parts:

  • Artificial Lily Flower
  • Flickering LED
  • Thermostat Wire
  • 100-330ohm Resistor
  • Mini switch
  • Solar-panel ~ 5vDC
  • Rechargeable Li-ion Coin-cell Battery
  • Rechargeable Li-ion Coin-cell Battery charger = TP4056 Mini USB 1A Lithium Battery Charger Module
  • USB to mini USB ~ 5ft. cord
  • Optional ~ hand-crafted vase station

Steps:

artificial lily flowers

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

remove stamen from the lily

  • Gut the Artificial Lily Flower by removing its pistil.

thermostat wire

wire strippers

  • 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? Probably.

  • 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.

battery charger

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

open them up!

  • Gut everything from the case!

drill a few holes

  • Drill a few holes. One for the solar panel wires, and the other for USB connector.

solar panel

  • 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.

assembled rechargeable power pack

  • Insert the switch and wrap wires so they lay flat inside the case.

testing assembled rechargeable power pack

  • Test the output.
  • Optionally, attach USB to mini USB cord to the charger
  • Store inside a hand-crafted vase station.
