First Idea

Some children do not want to sleep alone in their room, much less with the light off because they are still afraid of the dark.  Given this, the idea of my project arises: an image projector lamp for children, the same one that will be activated by sound (specifically by applause) an easy and fun way of operating for a child. 

That was my first idea, some things changed as I carried out the project: structure for the lamp, way of activating the light, among others.  

What does 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.

How the idea was generated?

"Lamp to treat nyctophobia in children" is the name of my project. The purpose of this lamp is to help children who are afraid of the dark and find it difficult to sleep at night, providing them not only with light so that they are not completely in the dark, but also with images that make them feel safe and happy.

My daughter also went through the same thing and sometimes she doesn't want to sleep alone because she is afraid of the dark; that is why the idea of this project was born. To achieve the purpose of making her feel safe and happy, the images that would be shown should be related to her environment, what she likes and her family.

Who's 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 did 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 were 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 did 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 did they cost?

What parts and systems were made? 

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

What processes were 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 were answered? 

• According to the tests you carry out, an 8-year-old child can easily exchange the images to be projected and quickly learn how the lamp works.

What worked? What didn’t?

• In the final tests of the project everything worked as programmed.

How was it evaluated?

• Tests of the operation and ease of exchange of the images to be presented with an 8-year-old girl were carried out, it worked correctly.

What are the implications?

• Once the lamp is finished, I would like to try other materials and other features (include music, for example).

Photo for recording in acrylic

I worked in INKSCAPE to get the outline of the photo I chose, there is no way for the program to generate the outline of the image by itself, you have to do the outline "manually".

Little prince in 3D

I chose this little prince ornament (free to use), because it represents the first book my daughter read.
