Blooming Flower Night Light (Remix)

To make a long story short, I was looking to create an enclosure to house a AC receptacle, controlled by an Arduino. I soon, stumbled upon Jason Suther's article which featured a blooming flower nightlight via Make magazine link: https://makezine.com/projects/3d-print-this-blooming-flower-night-light/. Jason's design, was very interesting to me and seem to be very cleaver. However, the base is what got my attention, as it was the perfect size for my project; Although the was the right size it did require a few modifications. At the end of the day, I found the process of modifying the STL. file to be problematic, and and deiced to model up the items which I wanted to modify. I have included the STL's and Solidwork files of the items which I have modified for this remix as well as a modified Arduino sketch which runs the led's for 5 minutes. I hope you can get some use out of it.

How I Designed This

Jason's design

The majority of this project uses the the Blooming Flower 2.0 STL files provide by Jason at: https://www.myminifactory.com/object/3d-print-37752

Jason's design uses a 1mm cable to connect the pedals linkage to the servo. I have opted to use a piano wire as it was sitting in my hobby box.

However the following items were modified in order to facilitate my design and personal preferences.

Pot-Lower.stl - Added a feature to the base which is used to house the AC receptacle. In addition, I selected to imbed 3 mm. threaded fittings to screw into the plastic to secure the Base-Lid and the AC recepticale.

Pot-Upper.stl - In order to facilitate the additional electronics, I was required to adjust the location of the power knob. In addition, the Pot-Upper contained a substantial amount of material which if felt could be hollowed out. This also allowed me to embed 3 mm. hex nuts to help secure the Pot-lower to the Pot-upper. It is also helpful as I can now run the wiring through the channels and keep them out of the way of the servo arm.

Screw_Wedge : This is not part of the design, it is only used to help secure the 3 mm. nuts into the Pot-Upper. I found that the angle which is required to mount upper to the lower was causing the Pot-Upper some damage as the screw was forcing the nut into it's seat. The wedge help with minimizing the damage.

Base-Lid.stl - The base-lid has been used as a mounting surface for the 120 v Relay and 120v to 5v power converter. In addition the lid has been modified to uses 3 mm. bolts to secure it to the Pot-Lower.

Electronics-bracket.stl - This bracket was changed to include a mount for a SG90 Micro Servo Motor and a sliding mount for the Arduino Nano. In addition, i wanted to ensure that the bracket did not flex and ended up using one of the Stems mounting screws to provide additional support.

Axis_12x_NeoPixel : In my hast to order the NeoPixel rings I inadvertently ordered the 12x instead of the 16x therefor I recreated the axis and the mount for the NeoPixel.

Axis_12x_36mm_NeoPixel: This is a derivative design fo the Axis which is intended to fit the HiLetgo 12 Bit WS2812 5050 RGB LED Ring. The inner diameter is 36mm.

The following Items have been added to the project:

Electrical_Plate.STL: Simply used to cover the face of the receptacle.

Purchased Parts and Hardware

These are the items which I purchased for the project

1 x Power Cord

1 x GERI™ AC to DC Power Module Supply Isolation Input: AC86-265V Output: 5V 1A (Amazon)

1 x RobotDyn - Thyristor 1 channel AC Switch (Solid State Relay), 3.3V/5V logic, AC 110V/220V/5A (peak 10A) (Amazon)

10 x M3 Brass Knurl Insert Nuts Metric Threaded (Outside diameter: 4.2/5mm) (100 Pack) (Ebay $6.00)

2 x 3mm x 20mm LG. Hex Drive Rounded Head Screws

4 x 3mm x 8mm LG. Hex Driven Flat Head Screws

1 small zip tie for to secure Power Cord

Some Glue for secure the Stem to Axis you could use Super Glue

General Notes:

Instead of using 3 mm. pins or Screws as the pivot for the pedals. I found a piece of 3 mm. filament which I cut to size.
