The idea of the sewing machine as a platform to charge mobiles was conceived maybe around the third week of our internship. With Derek's ingenuity
, Shibin's electrical knowledge
, and my ... ability to concede to crazy ideas... , the sewing machine was planned out with a good deal of research. The premise of the sewing machine mobile phone charger
revolves around the following points:
- Produce current sufficient for the charging of mobile batteries.
- Use materials that can be found off the street at the lowest price possible
So! Finding the parts...
Last Saturday we went down to the electronics bazaar down on Lamington Rd where they have everything related to electronics. While many of the shops tried to rip us off royally (shopping with a white guy with long blonde hair is not recommended for getting good prices in Bombay), the shopkeeper at "Vishal Electronics" was very patient, and helped us find whatever we needed. We got tons of little parts, including a few packets of JUMBO LEDs. Including the motor, gears, and circuits, we spent a total of about 10$.
Great! We found all the parts we needed... Now all we had to do was get the foot-powered sewing machine.
So we managed to find a street where almost every
shop sold new sewing machines--strategically located right next to the street where all the shops just sell doorknobs (??). So, after some serious bargaining, we managed to pick up a new foot powered sewing machine for around 25$. Done!
I should mention that it was kind of hilarious when we carried this thing into our fancy office building in the Bandra-Kurla Complex. We got all these looks of disbelief--people wondering why we would start a tailor shop in the IL&FS Financial Building.
