- | Computer fans were obtained from recycling e-waste (though fans with two wire worked best). Fans from power supplies and internal CPU cooling were used. After initial testing, it was found that most modern equipment used fans with motor controls that were much harder to retrofit. Increased weight was also a concern.

- | A template was developed to help participants create accurate shapes: the template was one half the kite, split vertically. - using an existing crease in the bag made this more efficient. Although black bags are more readily available, green or preferably orange bags make it easier to see the template outline after it was drawn. | + | A template was developed to help participants create accurate shapes: the template was one half of the kite, split vertically. - using an existing crease in the bag made this more efficient.

Because the final design required the membrane to be taped along the edge before cutting for added strength, initial cutting from the bag was about 1cm larger than the template. | Because the final design required the membrane to be taped along the edge before cutting for added strength, initial cutting from the bag was about 1cm larger than the template. | ||
