["Projector","Native resolution  > 640x480\nThrow ratio  < 3\nBrightness  > 1000 ANSI lumens","My project was based on the dimensions of the Ikea LÄTT whose inside dimensions are 2' x 1.5' (60 x 45 cm) and thus nicely fit the 4:3 image of a 2-throw-ratio projector 4' (120 cm) above the table","$300","Acer P1185","http://www.projectorcentral.com/projection-calculator.cfm"]
["kinect sensor","- V1 kinect (1414) i.e. kinect for Xbox 360\n- The kinect pulg is not compatible with a computer USB, sot buy a Kinect Sensor USB AC Adapter or solder a power supply (see on the left)","- An instructable to solder the power supply is here:\nhttp://www.instructables.com/id/Wiring-an-Xbox-Kinect-for-USB/\n- kinect V1 can not detect objects closer than 20” (50 cm) (limits the highest mountain in the sandbox)","$40","Used V1 kinect","http://www.ebay.com/itm/Microsoft-XBOX-360-Kinect-Motion-Gaming-Sensor-Bar-Only-Model-1414-/131787696725 "]
["Wood for the sandbox","- 8' feet of 1x10” wood board for the box \n- 100” stud\n- small stud for setting up the kinect sensor & securing the sandbox on the table","- pine or a harder wood for the box and the main stud.\n- lightweight wood like poplar for the small stud (the kinect is not heavy)\n","$20","see links","http://www.homedepot.com/p/1-in-x-8-in-x-8-ft-Pine-Common-Board-914835/100322328\nhttp://www.homedepot.com/p/2-in-x-3-in-x-96-in-Select-Kiln-Dried-Whitewood-Stud-845000/202059590\nhttp://www.homedepot.com/p/1-1-2-in-x-1-1-2-in-x-3-ft-Poplar-Hobby-Board-0Q2X2-27036C/202563493"]
["Junction elements","- 4 large steel angles for the box\n- 2 small steel angles for the kinect sensor support\n- carriage bolt and cap nut (stay free of any sharp edge)\n- nails\n","- stay free of any sharp edge\n- the stud supporting the projector are mounted on the box so take strong steel angles and heavy wood for the bax to ensure a stable structure (indeed up really fine in my case, I am not worried that the projector may fall)","$15","see links","http://www.homedepot.com/p/Simpson-Strong-Tie-18-Gauge-Double-Truss-Clip-DTC/100375299\nhttp://www.homedepot.com/b/Tools-Hardware-Hardware-Fasteners-Bolts-Carriage-Bolts/N-5yc1vZc2fj"]
["Play sand","- a bag of 50 lbs (25 kg) of regular sand is enough\n- alternatively: kinetic or any other indoor play sand (like Brookstone sand which is the same as kinetic sand or Sand alive that I also tried)","- regular sand is cheap but has to be regularly hydrated and tend to stick on the hands\n- kinetic sand is really nice but more expensive","- regular sand: $3\n- kinetic sand : $100-$150","Regular sand","http://www.homedepot.com/p/Quikrete-50-lb-Play-Sand-111351/100318476\n"]
["child table","- a child table for securing the box\n- alternatively: use some more wood to","- the Ikea LÄTT table is just the right height for children","$25","Ikea LÄTT child table","http://www.ikea.com/us/en/catalog/products/50178411/ "]
