Little BTL Amplifier - ZIPPO BTL
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
Thank you for watching.
