Introduction: Solar Powered Lamp
In this Instructable you will learn how to make a lamp that should charge during the day and then be able to operate during the night. It is a good beginning project for those looking to practice soldering and also those who want to delve a little into solar power and rechargeable batteries. Just remember to have fun.
Step 1: Materials
For this project you will need:
- A camping lantern (it doesn't matter what kind, although I recommend one that runs on 3 D batteries)
- A 6V solar panel
- 3 Rechargeable batteries (I used NiMH, but those are the most sensitive to overcharge, so you may want to use a different type)
- 7 wires (This will depend on the amount of batteries you need, I needed a 7th because the lantern I used needed one extra connection)
Step 2: Assembly
Solder 3 wires to each wire from the solar panel. Solder 2 of the positive wires to the negative ends of the battery case. In the picture above, it is the two lowered metal circles in the separate orange part. Then solder one of the negative wires to the the positive end of the the battery case. In the photo above, it is the elevated circle in the separate part. Connect the remaining negative wires to the positive ends of the two batteries, and the last positive wire to the negative end. Finally (in my case), I attached a wire connecting the elevated orange piece on the separated piece to the indent in the main lamp. If you've done everything correctly, you should have a lamp that can charge during the day and then be functional during the night. If nothing else, it will work when it is bright and sunny.
We have a be nice policy.
