Found @ CRASH Space No. 2: Industrial Staple Turned Meditation Chime

The staple-chime in its natural environment.

This heavy duty metal something was found in our scraped-of-the-floor bucket. Steve G says it’s a staple. It also sort of looks like a shim. If you know or have a guess, please speak up. The folks at McMaster – Carr couldn’t say.

Here is what I know about it:

What struck me the most about it for my purposes was the beautiful tone it makes so I decided to turn it into a chime.  So the big take away from this project: nothing is one thing.



It may be cheating as far as this series goes but I found a clapper from a bell used in a previous project in my own lab spare-parts section. It is high density plastic on a spring.  I even went ahead and and Arduino program to drive the clapper with a servo, the amount of time for the meditation based on the position of a potentiometer.

This is the staple and bell clapper I planned to use for the meditation timer.

In the end though I was driven to make too many iterations for the staple stand alone to fit into to my less-than-a-day-to-do-and-document time window for these posts. I would probably want a whole day more to really make a case for the chime, the servo and the Arduino. I have posted the svg files for the laser cut stand on GitHub as well.

This stand was cut on an epilog laser cutter with a thin plywood material from Home Depot that I’ve used to make a lamp. I based my stand on the files for this lamp. The tolerance is VERY tight on the slots. I needed a flat-head screw driver and a small hammer to secure the pieces together.

The settings for the laser cutter:
Speed: 30%
Power: 60%
Freq: 500 Hz

Increasing the speed to 50% sometimes works on this material but that is not what I did for this project.

I will definitely let you all know if I come back to join everything together into one piece. The biggest flaw in the stand right now is that it shifts when the chime is struck. In a mechanized version that is all one part, that should be automatically fixed.
