If you want to find your inner peace... over and over again, this might be an interesting project for you :-). Of course it is more a fun project than really useful. I just had the idea of making something like this and the execution is a little bit crude, but it works.


Things I needed to get this done:

  • Arduino (nano)
  • Servo
  • Breadboard and some wires
  • Soldering iron
  • Wooden bowl, box... etc.
  • Thin Plywood
  • Fine sand
  • and some household tools, nothing special

Step 1: Making the Lid

The box was flying around in our basement, so I just had to saw a lid from thin plywood. After I marked the center I drilled a hole and thinned the plywood a little bit to make more room for the servo. To complete this step, I just glued two pieces of scrap wood to the lid and screwed the servo onto the lid.

Step 2: Adding the Electronics

As for the arduino code I just took the example sweep code and added a delay at the beginning of the loop so that you have time to gain inner peace ;-).

For the power supply I took a 9v block and added it to a usb plug with a power switch in between, so that you can power up the "destruction feature" as you wish. For the cables to the servo I used some header terminals and soldered jumper wires to them so that the arduino can be easily taken out of the box. After everything was soldered I used some electrical tape to isolate everything.

Step 3: Making the Fork and Assembling the Box

As a tool for the micro zen garden you need some kind of fork. I made this out of scrap wood and three small nails. At first I just hammered the nails in but that made the wood split. So a pre-drilled the holes with my Dremel and that worked out fine.

A small piece of wire mesh was mounted onto the servo and so your sculpting will not last very long once the servo starts to turn ;-).

Thank you for reading and if you watch the video, you will see what this useless device does.

<p>uuuuummmmmmmm.... anyone else notice the 'Enraging' in the title, as in, make you mad?</p>
<p>or is it a typo and it means <em>engaging</em> mayby</p>
<p>Hi HLightning11, thank you for reading. I meant enraging as you mentioned in your first post.</p>
<p>Very nice! Just as a thought: using a motor for vibrating should be a) easier and b) reduce the risk of sand falling down the hole and mess the servo. Else a brilliant gift for nerds (like me) xD</p>
<p>Thank you for reading, Thomas. You are right. I think I have a broken PS3 controller somewhere and I might try this with the rumble motors.... Thanks!</p>
<p>I can't stop giggling!! So counterproductive to a mellow mood!!</p>
It is all about fun. Glad that you like it and thanks for watching ;-)
what exactly does this do?
<p>nothing more than stirring up the sand</p>
<p>That's funny!!! Messin with the Zen....</p>
<p>Thanks for reading!</p>
what is it?
<p>I have added a link to the video in the first step. Thank you for reading!</p>
no video link on mobile
<p>sorry, wasn't aware of that. I have added a link. </p>
