Interactive Devices Final Project: Obsoleting Instruments Concept.

The speed of our advancing technology and the technology that is getting obsolete are on the same pace, 15 years ago, we were using Floppy Disks, 10 years ago, we were still using Compact Discs and the millennials now does not know what a Floppy Disk is. We still see CDs now but they are getting obsolete really soon as there are lesser devices playing them now.

Choosing of the Best Appliances.

For this project, I want to give new life to daily objects which are on the path of becoming obsolete by making them a musical instrument, there are many common appliances that are in this category and should be ancient in a few years time –

CRT TV( Cathode Ray Tube or also known as the old Fat TV)”
Remote Controllers
CD and all devices which plays them
MP3 Player
Old Gaming Console
Top Loading Washing Machine
Landline Telephone
Fax Machine
Public Payphones
Answering Machine
Slide Projector
Dial-up Modem
Basic Alarm System
GPS Units

Bold are appliances which are totally possible for this project since I want to make musical instrument and they naturally produces sound in their normal usage context.

Green are appliances which are Bold and their normal usage context have the interactions when the user use them, which make them exactly what I could use for INTERACTIVE DEVICES.

Since the signification of a Gaming Console is different for every individual, people plays different consoles and different game or not at all, it is difficult for me to create something that all the end user(during the End Of Year Show) will resonate with.

Image result for landline phone
The best of all will be the Landline Telephone as I am sure that most of the end user will have some interaction with it some point in their life and the basic function of a Landline Telephone is to receive a call or to make a call, this resulted in almost the same user interaction throughout the globe – making a call or when the Phone Ring = Pick up.


And the Instrument that I have in mind…

After my researches on musical instruments,
I’ve decided to use the musical box concept where the user could play music by inserting a sheet of musical notes and it will play music digitally.

This could be done by using a set of lasers and photo resistors to read the musical notes on a clear piece of plastic scrolling through the system.

There are 14 sets of Laser and Diodes due to the research I had done on music theory(not posted yet as it is still an ongoing research) whereas there are 8 notes in an octave but only 7 different notes in an octave C D E F G A B C, so by placing 2 octave next to each other, there will be 14 white keys C D E F G A B C D E F G A B as I chose to omit the last C so that it looks visually completed from the looks of piano keys.

And what about the black keys? since I don’t want to add in 10 keys for the major and minor (black), I could use a combination of the adjacent white key to produce the sound of a major and minor. For example if I want the C♯(D♭) key, I could have CD shaded at the same time to produce a C♯(D♭) sound.

Flow of usage

  1. The phone will look like a normal phone with an exception of a slot to insert the musical sheet into the system in the body of the phone.
  2. Nothing can be done when the phone does not ring or the user does not make a call.
  3. Scenario 1 – Phone Ring -> User pick up phone -> voice command user to insert the music sheet -> User insert music sheet -> the phone pull the music sheet -> User listen to the music.
  4. Scenario 2 – Phone does not ring -> User Pick up the phone -> User hear the *toot toot toot* tone of the land line phone -> User dial some number on the number pad -> User hear the tone of an outgoing call -> Voice command user to insert music sheet -> user insert music sheet -> phone pull the music sheet -> User listen to music.


Robotics – Biologically Inspired Robots: Research part 1

What is Biological Inspired robots? First lets break the words into pieces.
Biology – The natural science of studying Life and Living Organism.
Robots – A machine capable of carrying out a complex series of actions automatically.
we could see that the Robotic studies has a lot to learn from the Biological side as most of the nature elements are refined through the years and it should be one of the most efficient way of doing things.

There are 2 methods from nature where robotic could potentially learn from which are

  • Imitating mechanisms found in nature (velcro)
  • Studying organizational principles from the social behavior of organisms(Swarming)

Imitating mechanisms found in nature


In robotics, bionics and biomimetics are used to apply the way animals move to the design of robots. Bionic Kangaroo  by Festo was based on the movements and physiology of kangaroos and one of the most well known Bio-mimicry of a bird was by Flying Machine by Leonardo Da VinciImage result for leonardo flying machine

There are many different variation of the bionics which replaces missing human limbs and they try to make it as close as the real ones, by producing a joint at where a joint should be, and although it might take awhile to get used to it, the technology is getting better over time and we are starting to go past the “Replacement of missing limbs” to “Enhancing human parts” since some of the Bionics worked better than our current limbs. *360 rotation of all joint? count me in.

This really inspired my projects in the turtle idea the spot is also an quad-pedal robot and I really love how it moves, maybe I could incorporate the idea of it into the turtle.

Notice how it move 1 foot at a time when turning and how it walks.


Studying organizational principles from the social behaviour of organisms

From the behaviors of ants, one ant may not be much and does not do much, with simple rules given to each type of ants, a society of ants will be able to do so much more and is really efficient. Hence on the idea of collective artificial intelligence in swarming in ants, fishes or birds, we could see the potential by using swarming in robotics by using local rules and global behaviors could allow us to scale the robotic ability into a scale unimaginable to us. 10 swarming robots could work, but 10 thousands swarming can do so much more, each individual robots just have to know where its immediate neighbors are.

The studying of insects like ants could really benefit the field of science and robotics.

This remind me of something that is in Big Heroes 6

Inspiration from this?

I’ll end this part of research here and if I have anything more to add, I will add them in another part afterwards.




Interactive Devices – Research 3: Music theory

As someone who doesn’t have and music knowledge, if I want to do a project on a musical instrument, it may be beneficial for me to learn some crash course music theory or some sort to increase my understanding of music.

Lets start from the fundamental of music, the physics.


These 3 videos are on music composing

Interactive Devices – Device of the week 3: Electric Paint Lamp Kit

Conductive paint had been here for some time and the application for seemed to be really a next level to interactive devices. This is an example of the usage of a conductive paint, Electric Paint Lamp Kit.

The Conductive Paint Lamp Kit is a simple product which springs from the novelty of Conductive Paint and what made it so special is that it is the most basic element of any circuits- forming connections between parts. With conductive paint, we could form electric circuits on any paintable surface which means the possibilities are only restricted by the surface and our imagination, In the Lamp Kit, it uses only simple Light up board, some printed paper and Conductive Paint in different combination to form 3 different variation of lamp, if we were to use other modules of sensors or output, I am sure that it would be really fun to play with these.

Like for example, if we were to use projections on top of the conductive paint on a wall, it would be like so.

This is definitely an interesting project to be done and would be possible for us to complete with our current knowledge after some explorations.

Another project which latches on the idea on a set of more advanced conductive paint is this, the Electroluminescent (EL) Device.

The Electroluminescent Strips could be created by using a few layers of different paints.

and how to create that exactly could be found here:

In Conclusion

The element of interaction within the Lamp kit not only acts like a Lamp, it is also a DIY kit which the user would participate in making it into a final product which gives the user a sense of involvement and increase their liking on the product as it was made by them. Maybe I could incorporate this idea of involvement into my final project where the users could create something that runs in the system which I created.

Also, Conductive Paint seemed really interesting to play with it and the potential of it is endless, we should be able to see better Conductive Paint and Conductive Paint Projects in the market really soon and I probably will purchase one to play with and maybe make it into a project or something.


Robotic – Final Project Ideas, Researches and Prototypes.

A Continuation from the previous Idea and Research, Part 1 where I wanted to do an Animatronic Turtle.

The Difference between a Turtle and a Tortoise is that all Tortoises are turtle and not all turtles are tortoise. Generally, Tortoise live on land and turtle lives in water most of the time, with exceptions which I’ll not go into. However in my Project, I’ve decided to use “Turtle” as I simply prefer the sound of Turtle more than Tortoise.

First thing.

How do Turtle/Tortoise walk?

Tortoise are cute! and the way they walk naturally are quite robotic =D

the “Hand” are much longer and the “feet” are much shorter in comparison. This is how a Tortoise retract its head, by bending its “neck” inwards. maybe I could emulate this.

29:43 – 30:20 where they talk about the locomotion of the tortoises

I could use a lever system to move the front and back legs so that I could use smaller motor and all 3 motor placed in the shell so the overall weight of the feet will be greatly reduced to allow me to use smaller/weaker motors.

From my research I’ve done and found this EEZYbotARM on Thingiverse which I could use it to study the mechanics I could potentially use in the feet of the Turtle.

The two motor is at the base of the mechanical arm(Typebot), in comparison to our typebot, This Typebot system is less efficient unless the torque of the motor far exceed the weight of the system and only a when there is a short (A) to (B) distance(longer fulcrum, more torque needed to turn it)

So to understand how fully it works and if there are any restrictions to this lever system, the best way is to having a study model to study how I could incorporate it into my Turtle. I also purchased a few servo few weeks ago and they also arrived so I used them in the study model.

The movement is really smooth and the movement coverage is definitely good enough for my turtle, However this system could barely carry its own weight as the base is relatively heavy, this Lever system could work great as a Type bot kind of project because doesn’t need to carry the base of the robotic arm, in my opinion, this probably wont work in my Turtle since each leg will still carry its motor weight because they are all in the shell, so having Motor(A) not carrying Motor(B) is of less importance since Motor(A) and Motor(B) will ultimately carry the weight of (A)+(B)+the mount+components+the shell in the end.

In Conclusion

I’ll need to find a more efficient system or use a bigger motor to do the work of lifting everything in the shell along with the motors and still able to cover the movements. Now my main concern will be

Weight of motor VS its Torque
Size of Motor (slightly bigger motor will result in MUCH BIGGER TURTLE which I’ll try to avoid as I wanted a COMPACT turtle, not a monster.)
Movements of motor especially within the shell.
