Every so often, maybe once or twice a week, Ugandan housewife Mrs. Moyonjo would bicycle twenty miles from her powerless village to the nearest city, where a strange industry of professional gadget chargers would recharge her mobile phone.
One day, her working battery was unscrupulously replaced with a battery with far less capacity, necessitating her Mrs. Moyonjo to make the twenty mile bicycle ride herself every day.
Like any real hacker, her response was an emphatic “Fuck that” and dreaming up a home brew solution involving a long string of D batteries. Which seems like a rather expensive solution, but at least batteries are probably sold locally.
Just a fantastic little triumph of a third-world maker, but the fact that there are entire businesses set up in Uganda dedicated to charging mobile phones for people is the real gobsmacker.
