As soon as an electric appliance breaks down or goes discarded, it is either thrown in the junk or is used for some totally non electronic purpose. Here is an interesting DIY post by Sreekesh which details with making out a night lamp using the same used electric parts which are not used anymore. The lamp is based on solar energy, i.e. one can charge the lamp in the daytime and get the output in the night, thus making the usage totally free. Moreover, if one makes the lamp from as many recycled materials, he can get the lamp done in quite low costs. Such prototypes can do a lot good in those areas where people cannot afford electricity at night. Recycled materials come in use when the chassis and switches of the lamp is made.
