- Piezo ceramic wafer
Reply
I’ve been checking the website of the company you recommend and I noticed that the wafer is way too expensive. Do you know where can I get the piezoelectric of these dimensions as salvage? I have worked with piezoelectric on clock signal generators for microcontrollers but they are tiny compared with the dimensions required for this project. Do you have any suggestion?
Thanks!!

It says you need a M324 operational amplifier chip. Should this be a LM324 because my electronics store never heared of it. Or other wise where can I order one??

- Nano or Micro Farad caps?

This looks like a fun project! The parts list in the magazine article states micro farad caps. The online schematic shows nano farad caps. I suspect nano ones are used but would like confirmation. Any thoughts?Posted by Paul Oh on March 31, 2008 at 11:14:41 Pacific Time

You are right. They are nano. There was a typo that didn't get fixed. Sorry about that.

This is very cool. I wish I could think of a project to incorporate it into...Posted by drysdam on February 24, 2008 at 18:41:24 Pacific Time

The first thing I thought of to use this for is for a base that would go below my turntables or even for the whole table that the stereo equiptment sit on. The less vibration that is going into the turntable the clearer the sound. People use all kinds of bases from marble to mdf to try to neutralize the vibrations. This would be a perfect application although on a bigger scale than the project here. I wonder if there would be any electrical or magnetic interference.Posted by namyen on March 25, 2008 at 20:25:15 Pacific Time
