After the second day we went to evergreen for observing and sharing elderly’s problems, now it’s time to make a project that can help the elderly to solve the problem.

My team, team three also known as soulmat3 team build a tools named PrevenThief. PrefenThief is a tools that can help the Elderly acknowledge who is coming, such as Official from evergreen or not. As we know some people can do disguise to steal the elderly’s stuff.

This system can notify the elderly whether a person who coming are official or not. This system use a card with QRCode as an access to visit and notify the elderly with a voice command. This system also have a sonar sensor that can detect a person on front of the door, and then the camera in front of the door can grab a picture of a person who stands in front of the door in 5 seconds with 7m of distance. So we can acknowledge who are the person come to visit the elderly’s home.

On this project, I learn about how to help other people with the problem that they have with the best solution and effort. And also I learn how to work with other people, even from the other country like Singapore’s student especially RP’s student. We can share our experience, our mind, our knowledge, our idea, and so on.

On Wednesday, we went to visit the Evergreen and Hollywood Veggie. The purpose of the visit was to find a problem, which will have to solve. After looking for information in the Evergreen, we got a problem. The problem was about the lighting system, and emergency ropes.

In the second week we were in Singapore. We’re doing some kind of research to create a lighting system with Raspberry-Pi. After discussion with the group, we agreed to make the Automatic Lamp System. This system uses the principle sum. When people go into a room, the sensor will count +1, and if there are people out of the room, then the sensor will count -1. As long as the value of the sum is greater than 0, then the room lights will turn on.

We decided to make an Automatic Light System simulator. Once we agreed with our project, we bought equipment and components we needed. After getting the materials we needed, we started working on our project. We create a program for the sensor, arrange sensors on the doors. Sensors made of two pairs of infrared transmitter receiver.

Sensors are arranged side by side, so that when someone comes from the right side to the left past the sensor, then +1, if from the reverse side, then -1. After successfully with sensors, we try to add other features to press the remote as an emergency ropes replacement. Initially we did not know what to use. Then Mr. Jason bought us a remote control relay.

This is Radio Frequency Remote, so that it can be used even obstructed by the wall. We have not used this remote module, so we had to try it. After successfully find a way of operation, we immediately add it to our project. How do remote module work is to emit radio signals at a certain frequency, then the signal received by the receiver, then the signal is converted into a logic 0 or 1 (low or high). The logic then used to drive a relay. So that the movement of this relay, then we use to turn on the alarm bell.

We also added a master switch to turn off all systems, especially when the user wants to sleep. In addition, the system will turn off automatically when no one in the house.

All of scholars from Indonesia and SOI students at Republic Polytechnic went to Evergreen where elderly live. We were given a problem and we have to find out the solution with our technology Raspberry Pi. As I told at my old posting when we visited Evergreen, we found many problems. And we have to discussed in our team about what technology we needed to use. Finally we decided to make a system that has two function observer and security system called Homade Pi. And the result will be reported or sent to the officer.

At Monday October, 12^nd 2015 we went to IDA Labs where we can see many interesting projects from any technology such as electronics, robotics, 3D printing, etc. We supposed to get ideas and as reference place to help us list down the components that we need to build our project. Then we estimated the price of each components, every teams will be given SGD 100. Furthermore, we went to Sim Lim Tower (Electronics Shop) to buy components.

The next day, Tuesday till Thursday we have to build our project. These are things that we needed and bought, but some of them has been provided by campus.

• Raspberry Pi as a mini computer
• Grove Pi as a bridge to connect Raspberry pi and Grove Sensors
• Ultrasonic Sensor to detect any suspicious movement in front of the door
• Gas Sensor to detect gas leak
• Light Sensor to turn on/off lamp automatically based on intensity of sun light
• Buzzer as an alarm
• LED as simulator to substitute lamp
• Wires to connect two or more components to raspberry pi pins.
• Bread Board to make circuit
• Resistors
• Pi Camera to capture any suspicious movement
• Wifi Dongle to connect internet

First day, we did installation OS Raspbian Wheezy and some Raspberry Pi’s configurations. And we also tried to make a circuit for the sensors and LED on bread board but we failed make sensor’s circuit. So in the second day we bought Grove Pi to make it easy without stringing wires on bread board. Then we just have to plug and play the sensor on grove pi, but before it we have to install library of each sensors and grove pi. For LED we needed to make simple circuit. In the Third Day we configured email and made the graph for display the record of the result as report.

 

 

 

 

I got so many experiences of making this project. I learned what is PBL (Problem Based Learning) and the way to solve the problem. How to communicate with user, actually it’s so hard to make other people understand our purpose. Some of them didn’t need any system to help their life, whereas I am sure everybody need technology for their life, they just don’t have enough knowledge to know it. So this is our challenge. And also we learned something new everyday together and built the projects together. And we have done the presentation well.

After at the 2nd day  we visit Evergreen for observing and sharing some story with elderly we finally do a thing that can help elderly with their problem.

My team (Timm1Team) is making Pi Light Up which is emergency lamp and house monitoring system using motion sensor and voice command. Why we build this? Because when we talking with the elderly she told us that she some time forgot to turn on the lamp when she go to the toilet in the middle of the night and make she cant sleep well. And also there’s a big issue that the staff ever find elderly that already passed away in her room and no one realize that for a week. We think that the best way how to solve that problem is using cctv to monitor the elderly, but the elderly having a privacy issue and don’t want to use any technology.

So we get the conclusion using motion and voice command to make the elderly save and can help the staff to take care the elderly without operating any technology.

What i learn while developing this project is how we can think how to give the best solution we have to every problem that given to us. And also how to work together as a team, share some ideas, share knowledge, share experiences.

This day we’re going to Universal Studio in sentosa island. We’re go there using commercial bus then after we arrived there the rest of it we’re having a lot of fun with Singaporean students and also Indonesian. We spend all day there, basically just have a loooooot of  fun there.

We’re end up tired in this day but we have  thousand memories of fun, sharing, caring and learn how to always stick together as a family of TF SCALE 2.

I cant wait this day because of today is where I will be in the most beautiful place in Singapore, Central City, and The Icon Merlion. First we arrived at Marina Barrage, the Marina Barrage is one of the reservoirs in Singapore. The guide briefed us and told about the roles of Marina Barrage. It plays an important parts in helping to alleviate flooding in some of the lower lying areas of the island. As we know Singapore is too hard in providing fresh water because of the geographic location surrounded by sea. So the place is also important in providing fresh water.

At 1^st floor there were galleries of water forming process. How The Marina Barrage works, why that is important to them and why did they made it. Sure they used sophisticated technology to turned sea water into fresh water. They created that place in case of Singapore often flooded at the past. So they thought about how to make something to prevent flood.

I learned the way they are thinking, so it may be able to apply in my country in Jakarta because of there is too often flood.

 

 

 

Marina Barrage itself have created some much needed recreational space. It’s a popular place to run, bike, sail boats, and take wedding photos. At the top of Marina Barrage we can see almost the central city of Singapore, especially the popular place such as Marina Bay Sands, Singapore Flyer, Flower Dome, etc. We did some group photos in there. We were so delighted to be there and see the popular places in Singapore at the same time at top of buildings.

Then we went around to Merlion. We passed Flower Dome, Helix Bridge, Singapore Flyer and many buildings. It was so exhausting but all paid off with the beauty of the city, The Merlion was surrounded by many tall buildings and the design of the exterior buildings are so amazed and wonderful.

Hey-hey-ho~

Enough with the playing-around-somewhere stuff. Things getting serious after we went to IDA and Sim Lim Tower to buy materials for our project. We looked around, looked around, looking for stuff we can use to develop our project using Raspberry Pi.

In addition, three days after October 12th was TIRING. We have to develop our project in those three (almost) sleepless days. Seriously.

Of course that efforts mean something. I learned how should teamwork will be. If a part or more doesn’t want to listen to others, that is not teamwork. Something may be done, but it won’t make each members happy or it won’t be as good as if the real teamwork runs.

Of course not only technical knowledge I got from those (almost) sleepless nights, but also this. If you want to earn something, you have to go through hardship and make efforts to be released from that hardship. I mean, look at this after our presentation.

Hey-hey-ho~

So I’m here again to write about my first week in Singapore, which is started from October 5th to October 11th. A week of fun, I have to say. After what I wrote in my post before, at October 8th, we gathered as respective team to do Raspberry Pi project. We were brainstorming, actually, about what is the problem(s) we found the day before in Evergreen and from that problem, we decide what system to make.

After that, in the evening, friends from RP took us to the Woodlands Waterfront Park. It’s beautiful to see sunset from there.

So yeah, my other adventure was in October 10th to Marina Barrage. I learned a lot of how is the system here in Singapore to produce fresh water. From what I heard, it’s pretty hard and thus I know why Singaporeans are very aware of water usage and promote to use water effectively.

And from there, they took us around (a very, very long walk, phew!) and our final destination for the day was the Merlion Statue which is a landmark for Singaporean. I must say that almost everything is useless when you do it alone, right. So that’s why human need others to live. So do I. Without friends, It must be boring to do even the most FUN stuff.

And the next day, we went to Universal Studios Singapore. What’s the purpose? Of course to HAVE FUN!

So after a week, I think what I learnt is to have a clean, and healthy life. It can be started from ourselves, like to not throwing rubbish away at any place. If we start from each of us (no need to ask others to do so), all people will do the same good thing (like what they do here in Singapore). Oh, and also to use water properly.
