    Know How... 242: AquaVase, Part 2

    We finish part II of our hydroponic vase using LEDs and a 3D printed stand.Project Overview We're adding decorative LED lights to our AquaVase Parts List These parts aren't necessary for the operation of HydroVase, but they ARE cool and geeky! :) WS2812 SMD Strips Arduino Voltage Regulator 26-30 AWG Silicone Wire Heat Shrink Tubing Tools List 3D Printer Soldering Kit Hot Glue Gun Screwdrivers Pliers All of the STL files can be found at: https://dl.dropboxusercontent.com/u/9042212/KH242_AquaVase_Base.zip Segment Summary We're designing a 3D object that can hold our 5" Vase and the electronics to illuminate the bottom. Interesting Design Features of the AquaVase_Base The bottom panel is 2MM thick and the shell is between 2-3mm The stands for the aluminum square tubes are 2-3mm thick and are supported by the bottom panel & their connection to the lower vase ring There are curved buildouts on either side of the lower vase ring that will hold the WS2812 LEDs There is a port towards the read of the base for providing power to the Arduino and WS2812s Shell_A Import a1_Hollow_BottomShell.stl Use the "Inspector" to turn the a1 into a "Hole" Import a2_Solid_BottomShell.stl Import a3_UpperVaseSupportRing.stl Import a4_VaseHollow.stl Use the "Inspector" to turn a4 into a "Hole" Export as "Shell A" Delete All Objects from the Build Platform Import b1_BottomShell_Platform.stl Import b2_Base_Hole.stl (Turn it into a "Hole") Import b3_VaseSupportRing.stl Import b4_RiserHollow.stl Raise b4 by 2mm Use the "Inspector" to turn b4 into a "Hole" Integration Import "Shell_A" Export BaseIntegration - Part II (Base)Procedure Cut your LED strips to match the LED holders in the Base Frame Measure/Cut/Strip/Tin your wires to connect the LED strips to the Arduino controller Solder your strips to the controller Pin 3 to Strip 1 DIN Strip 1 DOUT to Strip 2 DIN GND to Strip 1 GND Strip 1 GND to Strip 2 GND 5V to Strip 1 VIN Strip 1 VIN to Strip 2 VIN Solder the Voltage Regulator to the Arduino 5V to VIN GND to GND Load code to Arduino Attach LED Strips to LED Supports Run power out the access port Connect all power leads to the 4 channel Remote Cut one of the power wired to the pump and run it through Channel A (A-B) 12 Volt GND to the GND leads of the Remote, Grow LEDs, Full Spectrum LEDs, and Arduino VoltReg 5V Power to Remote, Chan B-B, Chan C-B, Chan D-B Arduino 5V to Chan B-A Grow LED 5V to Chan C-A Full Spectrum LED 5V to Chan D-A These show notes have been truncated due to length.
