Modified Version of Digital Weighing scale to eliminate the need of batteries

Description:- I've brought something new and creative on the table.This time the approach is to modify pre-existing conventionally used digital appliances/devices.

About Digital Weighing scale:- It is a device which is purposely used to measure weight. Most of them operate on 5 volt cells.

Challenges/Problems associated with traditional digital weighing scale for kitchen purpose. :-

1. Everytime you will have to buy a cell from market to operate this appliance.
2. Many people can't afford expensive digital weighing scale that operate on a.c power supply so they are left with only choice - they buy a cheap battery operated Digital Weighing scale. 
3. With due course of time the exposed cross-section of typical 5 volt cell gets corodded which,in turn, damages the metal part of appliance thereby making it unfit for further usage.
4. When cells get weak with due course of time we don't know about it directly. Consequently, the digital weighing scale doesn't measure weight of things accurately.
5. Since household folks use non-rechargable cells that won't run eternally so everytime they will have to buy cells.

Eliminate the need of batteries:-

I had a rc helicopter which flew away to a unknow house in my locality due to a loss of signal and never retuned back since then. 

It had a USB charging cable to the Li-ion battery.So I threw its remote into dustbin but kept with me the USB which , after 1 year , is a perfect fit for digital weighing scale for kitchen purpose. 

Just after the incorporation of this USB cable with the weighing scale the need of purchasing 5 volt cells has got vanished.

Procedure is simple:- 

•  In general, open any cell operated device/appliance and look for power supply connections.
• Solder the wires at positive and negative power sourc terminals and extrapolate them out of the device by digging a small hole or by any other means.
• Connect them with the USB cable pre-equipped with overcharging protection and a LED indicator.
• Insert it in a mobile charging adapter you trust and go with the flow.
• Voila! The Project is ready.
•  Now, seamlessly measure weight of vegetables, flour, rice or anything , as much as you can.
