17. Applications and Implications¶
This week I’ll be answering some essential questions for my final project.
What will it do?¶
My project is a surrounding interactive lamp. It will react to sounds in the room or music playing in the room. The lamp will also change colors based off the temperature in the room.
Who has done what beforehand?¶
This is something that really hasn’t been done before. I came up with the idea because I thought it would be a cool addition to my bedroom. So I am creating this project entirely from scratch.
What will you design?¶
I will design everything got scratch. I will design the base and sides of the lamp and I will be creating the electronics.
What materials and components will be used?¶

Where will they come from?¶
Every single part listed above was found in my Fab Lab. I did not have to purchase anything for my project.
What parts and systems will be made?¶
I will make the sides of my lamp with 1/8” thick wood. I will create the base with the 3/4” thick wood.
What processes will be used?¶
Laser Cutting¶
I will be laser cutting the side pieces of my lamp with the floral design I made onto it. I will also be using the laser cutter to cut out a piece that will help hide my electronics and support my Neopixels.
CNC Milling¶
I will be milling out the base of my lamp. It will be two pieces stacked that I will use to help hide my electronics as well.
Board Milling & Soldering¶
I will be milling out the board I designed then soldering the components mentioned above onto it.
Molding and Casting¶
I will be doing a 2 part mold to create a hollow half-sphere to illuminate and cover my neopixels.
3D Printing¶
I 3D printed the mold for my hollow half sphere. I also 3D printed two holders for the sides of my lamp so it can be held together without glue.
Interfacing¶
I interfaced both my sound and temperature sensors to read the values it was putting out to adjust the code and make the sensitivity correct.
CAD¶
2D¶
I used Corel Draw to create the floral pattern for my lamp sides. Then I used it to create my lamp base then exported it out to aspire.
3D¶
I used Fusion 360 to create models of me pieces and a model of my whole final project. I also used it to design the lamp side holders and the mold for my hollow semi-sphere.
Electronics Design¶
I used KiCAD to create a board specific to my project. I added all neccesary components in a schematic then designed it all onto the board.
Embedded Programming¶
I used Arduino IDE to program my Attiny1614 Processor through my SAMD11 UPDI Programmer.
Input & Output Devices¶
I used the temperature sensor and sound sensor as my inputs to display onto the neopixels which is my output.
What questions need to be answered?¶
-
Does the sound Sensor pick up background noise?
-
How good is the sensitivity of the sensors?
-
Is the temperature sensor made for indoor temperatures?
-
Is the lamp itself bright enough?
-
Is the lamp nice to look at as well as functional?
How will it be evaluated?¶
The lamp should be evaluated on the functionality. The determining factors are the sensors and if they do what they are told to do in the code. If the lamp picks up sound well and changes based on room temperature climates should be the main evaluations. Also a part of the evaluation is how it looks. Is it visually appealing and are the wires hidden? I believe that if all of those are up to par then project is a successful prototype.
