Bolas, or boleadoras, are throwing weapons used to trap / capture prey. Traditional bolas are made of weights attached to the ends of three connected sections of cord. When thrown, the weights will spin around the taut cords until the bola hits it's target. If the bola is thrown correctly the weights will have enough momentum to completely circle the target multiple times, wrapping / trapping it with the cords. (obligatory wikipedia link)"E"
is an abbreviation for electronic, it was very popular in the 90's before the whole "I"
fad. It can still be spotted today lurking next to mail.
This project describes the process of building a bola that uses LEDs and batteries as the weights, and a short length of cord as the cord.
