To start you Will take the cans and cut the lips off the top, so they can fit on top of each other. Then I cut three slits equally spaced apart. I also you Will need to poke some holes in the sides to allow air flow.
I tested mine out and found that I needed more holes so hooked some in the top. Before you continue be sure light the candle to see if it goes out. If it does then you will need to poke more holes. This step is all about trial and error.
In this step we will build the circuit. Just follow the scamatic and you should be fine. Other wise, I added the pictures of me building the circuit. Use them for reference when building it.
next I took my heat resistant epoxy and glued the cooler to the top can. I recommend placing something on top to prevent it from falling off as it sets over night.
this step is pretty simple, I trimmed down the circuit board.
To finish is simple, light the candle, cross your fingers, and hope for the best. If it didn't start charging right away then give it a moment becuase it takes time to heat up. Thanks for viewing, and don't forget to vote.
