-Archive of material relating to the design of the hacklab [[waterfall]] 
  
-==== Design challenges ==== 
- 
-====== challenge: Lasercutter ====== 
- 
-Grave produced a The [[http://​rebus.hydrus.uberspace.de/​edinburghhacklab/​General%20Holder%201%20-%205mm%20acrylic.DXF |linked file]]. It contains a pattern that needs to nest on an acrylic sheet 300mm x 620mm. 
-Find a way to setup the pieces that a maximum number, can be fitted on to sheet. We need to cut on our laser cutter 250 pieces of it.  
-For production we just have four full sheet and two smaller sheet in stock. 
-Smaller sheet: at least 300mm x 500 mm (Plus 80mm x 120mm) 
- 
-problem: inkscape v0.48 displays each piece as 210.140mm x 157.726mm :  
-confirmed: Max length - 61.5mm, Max width 46.15mm 
- 
-The file saved on jane's kay folder has duplicated elements stacked over each other in it.  
-[[http://​rebus.hydrus.uberspace.de/​edinburghhacklab/​close-pattern-test-1generalHolder%205mm%20acrylic.dxf |This .dxf file should be have no overlapping layer on it and can be used by the laser cutter software.]]

-====== challenge: Trough Construction ====== 
- 
-A trough needs to be built to sit below the waterfall, collect the water, and funnel it away to the tank that the pump is sitting in. It needs to be ~2.2m long (the length of the waterfall + 0.2m splash zone), ~0.4m wide, and ~100mm deep. The bottom of the trough needs to be raised ~0.5m off the ground (or at least, to a level safely above the required submerged depth of the pump). 
- 
-To cover the trough need material that is waterproof and more robust then black bin liner. ​ 
- 
-Grace suggested: 
-Garden pond material.

- 
-====== challenge: Frame Construction ====== 
- 
-A frame needs to be built to hold the waterfall. Currently the idea is to make the 4 black shelving stands (currently in the storeroom) into two A-frames. Each A-frame would be made by tilting 2 stands towards each other and bracing horizontally. These then have to be joined together at a fixed distance of > 2.1m (the length of the waterfall itself). ​
