Installation of piezo elements on the wheel
07/16/2018 at 18:14 • 2 commentsI have installed the piezos on the wheel with the help of the Double sided sticker! Otherwise, the piezo elements will be broken due to the heavy force by the wheel on the piezos.

Bridge Rectifier!
07/16/2018 at 17:07 • 0 commentsHere the piezo elements produce AC, So we want to rectify that. So I made a bridge rectifier for the rectification process using the four 1n4007 diodes.
We know that rectifiers are used to convert AC to DC, but not a pure DC. There would be considerable AC component in their output, called ‘ripple’, in addition to the desired d.c. component.
Most sophisticated electronic systems need pure DC supply to drive, or power them. To construct a good power supply which gives pure DC output, we need to remove or filter out the AC component from the output of rectifiers. As a filter I used 220 micro farad, 25 volt electrolytic capacitor.

Arranging the Peizo's
07/16/2018 at 14:57 • 0 commentsI have bought Ten piezo elements from the store for cheap.They are arranged in the series for hooking up in to the tyre.
