Individual assignment

Propose a final project masterpiece that integrates the range of units covered. Your project should incorporate:

• 2D and 3D design
• Additive and subtractive fabrication processes
• Electronics design and production
• Embedded microcontroller interfacing and programming
• System integration and packaging

Your project must answer the following questions:

What will it do? 

Once the lamp is energized, every time the sound sensor detects a signal (at the suggestion of my girl every time you blow on the sensor) it will activate the light change and the way in which this light is emitted; In addition, the images and decorations that are placed on the lamp can be interchanged.  

What has done what beforehand? 

Here is a list of projects based on lamps made in Fab Academy:

• Smart - Interactive Lamp, by Fab Academy 2019 student
• Led lamp with capacitive touch sensors, by Fab Academy 2019 student
• Lamp with ultrasonic distance sensor, by Fab Academy 2020 student
• I CAN SENSOR YOU, by Fab Academy 2021 student
• LUX the smart lamp, by Fab Academy 2019 student

What will you design? 

• The 2D design of the body of the lamp and the image in acrylic
• 3D lithophane
• The Fab Xiao RP2040 board

What materials and components will be used?

For the body of the lamp (box for the lamp):

• 3mm MDF

For lithophane and ornament (Image for free use):

• PLA filament

For acrylic image:

• 3mm acrylic

For the electronic part:

• Seeed Studio XIAO RP2040
• KY-038 sound sensor
• led strip WS2812B
• Breadboard FR1
• 0 ohm resistor
• 499 Ω resistor
• 1K ohm resistor
• 1 LED
• 1Button
• 03 Female Pin Header 1x3
• 02 Female Pin Header 1x5
• 5VDC power supply

Others:

• USB Type-C cable
• ON/OFF switch
• female plug connector
• connector cables
• Nuts and bolts

Where will they come from?

• MDF and 3mm acrylic from local suppliers
• The sound sensor and led strip from Naylamp Mechatronics - Peru
• PLA filament from KREAR 3D
• Electronic components from Amazon

How much will they cost? 

What parts and systems will be made? 

• Box for the lamp
• Lithophane and 3D ornament
• Acrylic image
• Electronics

What processes will be used?

• For the design of the box for the lamp I used Freecad and laser cutting.
• For the design of the acrylic image I used INKSCAPE, laser cutting and engraving
• For the design of the lithophane I used 3dp Rocks and 3D printing
• To design and manufacture the electronic board I will use EasyEDA and the process of milling and soldering.

What questions need to be answered? 

• Can it be used by children easily?
• Will the children be able to interchange the lithophane and the acrylic image without difficulty?
• Will the RGB led strip work correctly according to the programming before the signal sent by the sound sensor?
• Will any loud sounds detected by the sound sensor interfere with the lamp's operation?

How will it be evaluated? 

• That each time the sensor sends a signal, the LED strip must show a certain color and in a specific way (a single color of light continuously, change of color of light, variation of light intensity and colored lights).
• Ease with which children can interchange the lithophane and the acrylic image.
