You don't see it vibrating even though it has a high power and a frequency as low as 3kHz. You cannot see a high frequency vibration.

What will be accomplished in this Instructable? Completion of this Instructable will result in a piezoelectric energy harvesting "boot." With use of other electronic components, this unit will be able to power other small devices that have a low power consumption. Because of this change in the electric field, the piezoelectric material produces an output electric power. This rearrangement causes a change in the dipole density and therefore a change in the electric field between the dipoles. This is done by rearranging the dipoles of the piezoelectric material. This allows a mechanical force to be applied to the material to deform it slightly and the material will produce an output electric power. Piezoelectric materials exhibit the piezoelectric effect. For the £150 for a timer of eBay, do I scrap the idea? Or, it would be a really useful tool for a clock and watch repairer so is it worth putting the time in and making this, which I'm willing to do providing I'm not going down an impossible or very difficult path.**Patent Pending - United States 61928067** Introduction What is piezoelectric energy harvesting? Piezoelectricity translates to “electricity from pressure.” The prefix piezo in Greek means to press or squeeze. The second job would then be allowing you to select the KNOWN beat from a menu and it displaying the error + or - from what it should be, a much easier value to work with as you can then adjust the watch to try and correct the error.Īny help appreciate. The first job would be just listening and capturing the average beat time. We are describing a beat as a tick or then a tock. Would this be possible with an arduino? Most watches beat at between 4-8 beats per minute. These are available reasonably from China, they are a very very basically a pickup microphone, listen to the tick tock and time it. I repair watches and make clocks and I've always wanted a timing machine. Hi, I'm very rust with arduino and micro controllers but did a good few projects a few years back including making a coin change machine and a few other bits ( Homemade 10p Coin Change Machine - arduino, ch-926 and cube - YouTube)
