A teacher has to wear different shoes on different occasions. We become doctors, engineers, mashions, police, judge, accountant, and so on and we do just fine, and being scientist wasn’t very difficult either. It was during science exhibition last summer that I was working closely with my friend who was initiating the show. I got to see how skillful our students were in creating replications, but it was a rare thing to see anyone creating anything that is original. Everything seemed like inheritance from the past batches- volcano, hydraulic machines, steam boats, lighting bulb from potato, ... My friend asked me if I could show them what a science exhibition means in simple terms, and I said I will illustrate with a simple invention.
The inspiration came from necessity. Every household needs a sangphoo each, and sangphoo needs burning charcoal to function, which is not available any more. Worse even when we have to offer a suu in the middle of the night when someone falls ill, the idea of starting the fire in sangphoo is a big hassel. This gave me the inspiration of creating an EzSangphoo that could be started at a click of a button.I completed three prototypes and presented during the Science Exhibition but because I was not participating in the competition I kept it at the gate and made the chief guest click the button, what happens next is seen in the picture!
Built: EzSangphoo is built on normal earthen sangpho with basic circuits and everyday objects. The challenging part is controlling current flow to the filament, because the size of coil used in it is so small that it will blow off on 240 volts. Moreover using 240 volts in a sangphoo, which is expected to be used mostly by old people, could spell electrocution risks. Therefore we need to have a special device that could adapt the current flow to less than 12 volts.

The simple idea can be replicated by anyone for personal use, but if someone wants to mass produce this then please notify me, so that I could take you to the court lol.
