I thought I could do something cool with a coke-bottle so I thought.. what about a lamp and here it is...
What you need:
- Soda-bottle (the older looking, the cooler)
- Two wires around 10-12 cm
- Two LEDs, with your choice of colour, (I used white ;))
- Two resistors, size depends on you supply voltage, since I want it bright and my supply voltage is 5 volts from USB, I used 120 ohm
Corrections and questions will be appreciated.
Step 1: Cleaning
just to get the last bit of coke out and removing the sticker if the bottle has one.
