This is a simple normal flashlight with a weird but cute shape developed from its material which are all from shop and junk shelf. At first I pick up a L shape wood with one tiny hole one the extension L leg. Due to LED fits hole to this tiny hole, I decide make it the light source of this flash light. In the second phase, I drill one big hole and one small hole and for battery and wire. Unfortunately, I found that one battery cannot drive the LED I get from shop. To solve this problem, I found another wood piece from the junk and drill a hole to carry another battery. At last, I cut a piece of card board to cover some hole and wire as enclosure.
Finally. it works!!!
1. never build a battery carrier by ourself
2. measurement and plan matters!
