My friend had built himself a new amplifier, and once I saw it I think I need to share this amazing amplifier to others.
The one on left hand side is a lighter amplifier my friend made before, the right one is this time 'lead'
Follow are the building process of this ZIPPO BTL from my friend
1. Draw a 1:1 image of the amplifier and test the size
2. Solder parts
3. He used 1 3.7V Lithium-Ion battery, 3 opamp this time and use IE80 to test
4. Key point of ZIPPO BTL, a ZIPPO Lighter. Open holes on it
5. Finally, insert the amplifier into the ZIPPO Lighter
FINISH
Thank you for watching.

An externally hosted image should be here but it was not working when we last tested it.

What is the purpose of the third op amp?
2 of the opamps are for BTL
1 of them is the buffer before VR
