As part of the second prototype, I am looking at making the casing look more futuristic and use interactions that are more independent and less dependent on humans. The clock would be represented in a manner different from the normal analogue or digital view we see. The ultrasonic sensor will be replaced with the representative clock to send updates to the screen. Even powering the jellyfish would be a remote activity from the screen rather than manually doing it.
I was suggested to use a more organic look for the casing. However, considering our futures would be more compact and there would be a fight for space. So I am looking at a more compact design rather than the organic look.
Jellyfish are fascinating creatures that use bioluminescence to attract mates, distract prey and capture predators. They are expected to have a short life span of 1 year and usually bloom in spring or fall. Some species also bloom more than once a year. Jellyfish blooms have been seen to be on the rise since the 1980’s and much of it is contributed to human impact on the environment, which led to global warming and eutrophication. The blooms are also on the rise due to fishing activities and aquaculture. This rise in jellyfish population has negative effects like reduced tourism, clogging of thermal power plants and diamond mines, changes in sea beds and marine ecosystems. Some researchers predict, that at the current rate of bloom, the population will continue to grow for another 100 years.
In my project, I would like to focus on the problem of this problem, and imagine a future where only jellyfish cover the aquatic life and are the only available resource. So I would like to create an iteration of how jellyfish can be used for multiple purposes. Since jellyfish cannot be kept in regular fish tanks, and we’re out of most resources, the jellyfish is biomimicked to be kept in a regular fish tank.
Jellyfish would be the source of many things like:
- Power supply
- News update transmission
and so on.
The ultrasonic sensor would be the inducer of all of the above. Blocking the ultrasonic at a certain distance would make run the servomotor, which would make the jellyfish move vertically up and down. The servomotor would resemble the production of power supply. The LED on the jellyfish would change color over a few seconds, depicting that the required amount of power has been generated and stored in the jellyfish.
There would also be a clock that moves around the tank. When the hour hand is before the ultrasonic (the distance being closer than required for power generation), there would be an update on the website (operated from the phone).
The update would show the following information:
- Current time of the day (imagining time is difficult to tell since its perpetually dark due to pollution)
- Latest disaster or issue identified around the world
- Home temperature status
- Outside weather status
- Stage of jellyfish bloom (imagining every household has to manage jellyfish aquaculture to create their food)
- Quantity of edible jellyfish available for current consumption
Learning how to use LED lights in class, I tried to combine them with sound. So I used the say.js and gpio.js packages to complete the assignment.
Say.js uses the Festival speech synthesis system, supported by Linux, to convert text defined in the code to sound. While GPIO controls the switching on and off of the LEDs.
I combined the two to show the changing of the lights. When the green light switches on, the pi says ‘Hi! Turning light green.’. Whereas, with the red light on, it says ‘Bye! Turning light red.’
A similar system is used at certain traffic light to notify blind pedestrians for crossing. The sounds they usually use are single chirp sounds or beeps. Below is a link from youtube to show how that works in reality.
A smart watch is a computerized wristwatch with functionality beyond timekeeping. Smart watches, that began with basic functionalities like calculations, translations and game playing, are now effective wearable computers.
They offer various operations like:
- Running mobile apps
- Mobile operating systems
- Portable media players
- Mobile phone capabilities to answer calls
They can be made more complex in functionality with camera, measurements, GPS navigations, map display, activity tracker, heart rate monitor and so on. It may support Bluetooth, Wi-Fi or GPS and may be enabled to control and retrieve external data.
There are multiple companies offering smart watches in the market today. Some of them support mobile phones like:
The Hamilton Watch Company introduced the first smart watch in 1972 with a digital display created from LEDs. They progressed from including Microsoft Office in 1994 to a Linux wristwatch in 1998 to integrated speaker and microphone in 1999. In 2000, it was upgraded with accelerometer, vibrating mechanism, calendar, Bluetooth, 8MB RAM, 16MB flash memory and fingerprint censor. Since then, it has been launched with features like Palm OS, LCD display, an external Bluetooth display, and eventually smartphone capability.

Drone is the common name for and unmanned aerial vehicle (UAV). They are used in situations where manned flights are risky or difficult.
There are 2 types of UAV:
- Autonomous aircraft – operated by an automatic system
- Remotely piloted aircraft (RPA) – operated by an external operator on the ground
UAVs have six functional categories:
- Target and decoy
- Research and development
- Civil and commercial
The use of drones is shifting from primarily military to other civil aspects like commercial surveillance, filmmaking, journalism, law enforcement, search and rescue and so on.
A lot of companies like Frog Design or Good Drones LLC are in the practice of designing drones to aid everyday life. For instance, Frog Design came up with a drone concept called ‘Firestorm’, which is fire rescue drone to scout victims before the rescue squad prepares to enter. Another concept is ‘Cyclodrone’, a flying beacon connected to the bike rider’s phone, on a predetermined route. Its purpose is to improve visibility and reduce accidents on narrow roads.
