Today i had a transparent peace of a packaging and there was a scrape in it.
But when i went to the rubbish bin i saw that the scrape in the packaging cached the light from my lamp and reflected it.
This brought me to the idea to scrape some marks into it and illuminate it with a green LED.
Well, after i saw the result it didn´t took long for me to build a scale Heads Up Display (HUD) .
The bottom plate is made from Depron and the black struds at the side are made from cardboard.
It looks pretty cool and it´s also verry light (about 1 gramm).
