0 Point Ruler is an interesting concept ruler to solve the minor issue we usually encounter from using conventional ruler where we have to adjust to 0 point to draw a line in order to have an accurate measurement. To eliminate that process, this concept ruler automatically starts at 0 point each time your pencil touches it, it marks the numbers that go before and after.
The top side of 0 Point Ruler has been designed to be a pressure-sensitive touch screen which requires electricity to work. There’s a built-in generator that utilizes kinetic energy generated when you stick your finger into the gear and rotate it.
