Routing the money, that you owe from the shopkeeper which is returned as candies, to charity

Idea: Provisioning the flow of petty cash to charity, which is to be returned to you in place of equivalent costing candies.

Explanation: Atleast in India, I am aware of a problem that when you buy something from shops, many shopkeepers don't return the full denomination of cash that you owe in return to a whole number denomination that you pay. Instead, candies for the equivalent cost are returned to you.

For instance, if I buy a book worth 87 units from a shop by paying 100 units currency, the shop keeper usually returns 10 units currency and for the rest 3 units, candies are given. This is becoming a usual trend and growing.

 How this idea can impact you: In this idea, we somehow enable a system where in you force the shopkeeper to transfer the remaining quantity of money to charity needs, and not accept candies worth for the amount.

Feasibility: Will find it out

Purpose of the idea: Non-profit/Charity

Road ahead: To be decided

AC current for half duplex communication

This is my first blog post on my !deas.

Today I got an idea of using AC current for half duplex communication.

Idea: Using a modulator which intercepts the AC and slightly modulate and transmit it through the same wire. A device which could be clipped to the wire (probably of magnetic origin) can sense the fluctuations produced by the modulator, decodes the message to the computer.

How this idea can impact you: Imaging you plug a special USB device with USB socket on one end and a clip on the other end which is clipped to your table lamp wire. And guess what, your computer is receiving some data from the wire!

Feasibility: Will find it out

Purpose of the idea: Fun
