DIY Camping Lamp from useless stuff

I've found two pieces of lithium battery from old mobile phone.

A charging circuit board from a dead battery pack.



And a LED panel from a dead desktop light.



By adding a simple switch, a new camping light were born:

I made a paper box to cover the battery.

With this battery pack charging circuit, the charging speed is now faster.

I used a mobile phone mounting to fix it on a small tripod, and then to use it in actual scenario.

It has been over 8 hours and it's still up and kicking.

More than enough for overnight camping.

Weight reduction, some DIY work

Drilled some holes around the handle of my pan, forget to record the weight before.

I believe around 2-3g and maybe 5g maximum?  Anyway, it's easy and no harm to the functionality.

I am not those kind of ultra-light person, I just want more weight reduction for easier hiking, and maybe even bring more stuff or food.

I checked the original weight from the manufacturer, and they said 40g.  So the weight reduction is 5g which means 12.5%.
