If you have not read the previous post (Part 1) on this subject, I encourage you but it is not mandatory to do so before reading this post. I’ll still go through the fundamentals in this post. If you just want to see the raw technical details, the schematic and code of this project have been open-sourced here.
I’m part of this voluntary social initiative called Repair Kopitiam (RK) started by the social enterprise Sustainable Living Lab. On a monthly basis, we teach Singapore residents how to repair their household electrical appliances, fabrics and furniture. Our volunteers are called repair coaches. This initiative is similar to Repair Cafes which originated in Europe. My area of speciality is of course in the electrical appliance department.
It is not everyday that one is like a tourist in our own country. I went on a trip with my fellow Repair Kopitiam coaches and others for a practically once-in-a-lifetime experience to Pulau Semakau, an island located 8km south of the mainland. It is affectionately known as a landfill island, where our incinerated trash gets sent.
