Final Result

 

 

The idea for this project came from wanting to create something new, useful and design-oriented. I was inspired by thinking about what I would like to do when I get home and relax: I would sit on the sofa with a glass of red wine and listen to music, recharge my smartphone and turn on a soft light, not too intrusive.

 

 

THOUGHTS

I first thought about the design of the project and wanted to create a simple design that wouldn't clash and could be easily placed anywhere in the house, from the bedside table to the dining room

ELECTRONICS COMPONETS

 

 

 

 

WHAT COMPONENTS DO I NEED?

I definitely need a wireless charger to charge my smartphone, I need a speaker to listen to music and then for the light I decided to use a LedRing

 

 

REALIZATION

The first thing to do is the box that will contain all the other elements, then through Autodesk Fusion 360 I make the sketches of my box and then I save them in the format readable by ShopBot and I mill it including holes and cuts

The second thing I do concerns my LedRing: I draw the PCB in Eagle that will run my LedRing and I go to solder the various components

Once I've done that, I use Arduino to program my Attiny44 so that the LED changes colour every few seconds. To be able to switch the LedRing ON and OFF I will put a button.

 

I HAVE CORRECTLY PROGRAMMED MY ATTINY_44

 

 

Now that my LedRing is working and the program is working, I have to think about its support and to do that I use the 3D printer. Since I need a magnetic base, while printing I put a magnet on both the LedRing support and the support inside the case so that they attract each other.

I have a doubt: since the components of my project use different voltages, I need to create a PCB where I will solder a Voltage Regulator in order to manage correctly all the voltages of my project.

Now that the stand is working and the magnets are in place, I can concentrate on the speaker: first I attach the speaker to the inside of the case, then I have to figure out how to connect the cables and what they correspond to. One of the cables corresponds to the 3.5" jack where I can plug in music. The other cable I will solder to the PCB.

KACK 3.5

 

 

 

 

Once the speaker is set up, I deal with the wireless charging that has a MicroUSB input on one side and on the other side it will be attached to the PCB so that it receives electricity with the right voltage, since there is the Voltage Regulator. Then, with the 3D printer I print the base measuring the space in the box and making sure that my device can be recharged without problems.

Since it is not very aesthetic to see the speaker cone, I use the 3D printer to print a cylinder that will cover the speaker on the box.

Now that all my devices are connected I have to attach the SUPPLY, which is the connector that will bring all the voltage to the board that will then carry it to the individual elements.

SPEAKER COVER

 

 

 

 

All the cables are in place, but they are "floating" in the vacuum and risk detaching and unplugging the components, so I decided, with LaserCut to laser fixtures so that the cables are kept in place and not "floating" in the box. At the same time, though, if I need to remove, change, or adjust the cables, I have to make sure to remove them, so I chose a size where I can still pull them out.

I have a doubt: since the components of my project use different voltages, I need to create a PCB where I will solder a Voltage Regulator in order to manage correctly all the voltages of my project.


 

 

 

 

 

 

NOW I TRY TO ASSEMBLE EVERYTHING TO SEE THAT EVERYTHING WORKS CORRECTLY AND IF NECESSARY MAKE CHANGES.

 

 

 

 

Assembled everything I realize that the support of the LedRing is not very nice because you can see all the wires inside, so I decided to laser a piece of plexiglass in a colour that matches the colour of the support so as not to see the inside of the support.

 

 

 

 

!EVERYTHING WORKS! But since I don't like the look of it, I decided to use the Vynyl Cutter and then attach black vinyl around my project

 

 

 

 

NOW IT HAS TO BE TESTED TO SEE IF IT WORKS

PREVIEW OF MY PROJECT

 

 

 

 

 

 

 

DETAILS:
- This project is only a prototype, in the future will be applied some changes such as Bluetooth module for the speaker, a wireless charger crafted and innovative, maybe a touch controller on the base to turn it on or to adjust the volume of the speaker and other details to make it then unique and innovative and make it not only a project but also a design object to be proposed to the market.

 

- In addition, in one of the two magnetic bases there would have been the magnetic fluctuation module but unfortunately there were problems with some electronic components so it could not be realised but it will certainly be an update that I will do in the future.

 

 

 

 

ANSWER TO QUESTIONS:

 

What does it do?

- Is an interior design object that charges a wireless device, plays music and relaxes you with a soft light.

 

Who did what first?
- First i made the box to contain everything so that i could see the total size and especially if there was enough space inside for all my electronic components.

 

What did you design?
- A hollowed out "box" that could contain all my electronic and non-electronic components.

 

What materials and components were used?
- MATERIALS: wood, PLA, metal, MDF, PCB
- COMPONENTS: speaker, wireless base, cables, led ring x12, attend_44, capacitor, led, resistors, batteries put in series.

 

Where do they come from?
- Some parts i bought but only for time reasons (wireless charger, speaker cone), others i made myself in the workshop.

 

how much did they cost?
- Making an estimate once the project is finished, considering everything and the possibility of customising the object according to the home furnishings, I'd say about €500.

 

Which parts and systems were made?
I made the general box of the project, I printed the magnetic bases (with the magnet inside), the support for the led ring that would contain all my electronic components, I changed and soldered all the cables, lasered the cable clamp, programmed my attiny_44, milled and soldered all the boards in the project (led ring and Voltage Regulator), put vinyl on the outside of my project to make it look better.

 

Which proc esses were used?
- Milling
- Laser cutting
- 3D printing
- attiny_44 programming
- Vinyl cutter to put a cover on the perimeter of my project
- welding

 

Which questions were answered?
- When I thought of this project I thought of the question: What would I like to have, to do in the evening when I got home and the answer was that surely my devide would be a bit drained, but I would like to listen to some music with a soft light.

 

What worked? What did not?
- In general everything worked, but in the details the LED did not change colour as I had programmed it, so I reprogrammed and revised it.

 

How was it evaluated?
- Interesting, but some parts needed modification: the led ring did not change colour and therefore had to be reprogrammed.

 

What are the implications?
- The implications are: studying the project in every "comma" and then learning things I didn't know before.
