Now i simply needed to box all components up into one case and make it portable. Yes, on wheels! It’s quite a 3d tetris like task to assemble components.

In order to have a real tuned car look and feel, i had an aluminium sheet lasered and painted with a so called “harlekin” finish. It changes colors depending on the angle you look at it. Basically it is hell of expensive. But my paint guy had some rest from a huge job.

So I would like to thank the anonymous donor of  my harlekin paint. Maybe it was this guy? A Hummer with exactly the same finish as mine…

After assembling and cabling of prototype 2 were still irregularities. This time with the servo. After using shielded cable wherever it was possible, the problem diminished.

As I figured, hacking a brush isn’t that easy, I had a look at how industrial engineering companies are solving the problem. Well they use an air compressor and a dispensing unit. Fair enough, one can fiddle very precisely with it.

The workbench with all components:

My first prototype wasn’t so chic and the electromagnetic field caused by the magnet was so intense, that the stepper motor was uncontrollable. Therefore i planned on doing a new design with a gearhead dc motor and more powerful bass shakers.

Here a picture of the paper prototype i had then lasercut in stainless steel.
