Background: Mekong Delta has been struggling to get fresh water due to droughts – and salt intrusion becomes harder and harder. How the system works: We use https://thingspeak.com to create account to upload data of salt level in water, so everyone can see the data from this page.
Background: People with disabilities can find it hard to use/control smart devices. Therefore, we chose this topic to help these people to access smart devices more easily. How the system works: The program is coded in Python, with face recognition When a user moves their face up-down-left-right… the mouse arrow will move accordingly. Eye blinks are equal to left/right click, closing both eyes means the mouse will glide up/down depending on the nose movement.
“Previously, we just saw a vending machine, but we didn’t know how it works. So we got quite curious and imagined, one day we can build a vending machine on our own” Chan Tran said. Our vending machine uses magnetic cards to scan, record and confirm identity of users (especially at schools). The USP being, that the machine can connect to the parents, so the parents are in control of what the studnts buy at school. That way, they can controle how much money is being spent and what the kids consume.
The farm has a water storage channel, which is used to water the leaves of the plants. When the humidity is below 65%, the drop irrigation system will be activated. The lighting and watering/irrigation systems are controlled via website. The roof works with automatic opening and closing depending on the light, temperature and rain sensors.
There is a push to find medical equipment that may be used to help COVID-19 patients. A team of young students, aged 12-15, in the Mekong River Delta in Vietnam, is working on an initiative to develop a prototype for a low-cost breathing machine. 30 club members have been guided by Dariu’s technical advisors to assemble two different designs, including an open-source blueprint from the Massachusetts Institute of Technology (MIT). Some parts of the ventilator are 3D-printed by the students. There are groups of university lecturers, students, and researchers trying to develop the prototype in Vietnam. However, these are the youngest kids being on a life-saving mission.
The idea is to develop an environmental friendly and floatable house that is adaptable to seasonal floodings in the Mekong River Delta. The house is made of bamboo and equipped with smart technology. Micro:bit is used as the central controlling system to connect and control other external sensors, such as lighting, humidity and proximity, and motor servo. The humidity sensor is used to transfer a signal to the Micro:bit to operate the house with up and down lifting; the light sensor for auto-lighting; the motor servo for opening/closing the main doors.

When looking at the container library donated by The Dariu Foundation at his schoolyard, Cuong Tran, 14 years old, told his classmate Phu Nguyen that he wished the container library were movable, so that they could move it from school to school. They decided to develop a movable house as their summer project. Micro:bit is used as the central controlling system to connect and control other external sensors such as lighting, humidity and proximity, and motor servo. A light sensor is used to transfer a signal to the Micro:bit for automatic lighting; a humidity sensor is used for watering, and pumping; a motor servo is utilized for opening/closing the main doors. “Our dream was to make a house that’s able to fly like a drone,” said Cuong Tran.
During the school closure, a group of students, aged 12-15, has been filling their free time by operating their 3D-printers to produce little plastic parts, known as ear savers, to help health care workers taking part in the COVID-19 response. The group found the design online and received the 3D-printers with support of The Dariu Foundation, to produce ear savers, designed as ear relievers for masks that the health care workers wear. And the demand for such ear savers has been huge. The students can print four at a time, each batch taking about half an hour. With breaks, one printer can make 60 pieces per day. They were able to send 1,000 pieces to health care workers at local district hospitals, to give their ears a break from the pressure of constant mask-wearing.
A group of secondary girls recognized that waste disposal was becoming a huge problem where they live in the rural Mekong River Delta area. People threw all kinds of waste into dustbins – a very common practice. They wanted to create a smarter solution. They developed a garbage truck using the Micro:bit device, which helped classify solid and recyclable rubbish, before being sent to treatment factories. They got to present their device to the Deputy Head of Vietnam National Assembly Committee for Culture, Education, Youth, Adolescents and Children, the deputy head of the ICT Department of Ministry of Education and Training, and Country Director, Vietnam, Laos, and Cambodia – Google Asia Pacific.
The system uses a sensor to measure air quality. Once gas/CO2 is detected, it sends a signal to a relay, to turn on a speaker, which then warns the people in the room with a loud noise.
All the patient’s information, such as blood pressure, pulse etc. are monitored and appear on the screen, next to the bed. The system sends a warning signal to the attending doctor/staff, if any of these stats are irregular and/or of concern.
