10. Mechanical design & machine design
This week we used prototyped machine called Echo Garden . Maxumum idea was to create machine reproducing melody sound createrd by user and inflate "flowers" made of vinyl film.

- Relying on founded draw wistle was modeled and ptinted, but its tint was to high and sensitive.
- To make it more tunable we tried to scale up inner hole (the outlet point of the injected air) and scale down width of air cutter excise. In result scaled up did not work well, scaled down became lower and less sharply rising, but still not well manageble.
Concluded that need try to scale wistle referencing to acrilic tube volume and diameter, so shifted from wistle to organ contruction.
- Exist 2 organ pipes types according to the principle of sound extraction: Reeds and Labial. Labial (reference) have differenses in constuction, so few refences were used.
- Detail have cone part with expansion, bending wall for air flow smoothness and outlet crevice ( 1.35 mm ), second part is tube with rectangular hole and blade.
- Tried two modifications: ears (concentrating external air flow) and smaller blade-crevice distance ( 18 mm -> 9 mm ).
- Was used tree type supports to reduce consumption of material, wall layers count changed (2 -> 4) to make wall ( 2 mm ) more solid, safer and probably better for resonation.
- Used three less collibrated printers for spare print.
- Printed well, fits accurate, sounds deeper and smoothier.
