I bought some solar powered lawn lamps at Dollar Tree so I could make more battery chargers* and also because I wanted to see what else I could make with them, so here we are!
*See them here: Solar Charged Battery!
From one lawn lamp I collected these items:
- AAA Battery holder
- # Metal pole
- # Clear plastic cup
- # Metal head
NiCd Rechargeable AAA battery: 1.2V, 200mAh
YX8018-5v431 LED driver IC
- 4.7K Ohm Resistor
- #Low current LED
- #0.55V Solar panel
The ones with a # symbol I will give instructions for something to do with it.
Step 1: Take Apart the Lamp
Tools you will need:
- Phillips head screwdriver (almost any size)
- Wire cutters
I found that most of the big parts just popped off when I pulled them. Next you have to get to the Electronics:
- Unscrew the top piece (3rd & 4th pic)
- Remove excess glue from anywhere (5)
- Cut the wires from the solar panel (6 & 7)
- Carefully pry off the solar panel (8)
- Scrape off excess glue(9)
- Unscrew the PCB (10 & 11)
- Desolder the electronic parts (12) - How to Desolder
Save all of the parts!
Step 2: Uses for Your Parts
- Large metal tube - Fits NERF darts perfectly
- Metal base & Clear plastic cup - use to make an attachment for your flashlight to turn it into a lantern -Flashlight Lantern
- Battery - use with a battery charger
- LED - great for a Joule Thief because it uses a low current - Joule Thief
- LED driver IC - see the data sheet for it here:
- Solar Panel - 0.66V and 0.55 Amps: use with the same battery charger as above
