R2D2 spraying fog !!!!

I used a smoke spraycan, the name of this spraycan is " Magican" probaly there are other brands to, i found this spraycan here in Belgium.

Mounted in front of the body . On top of the can a lever is mounted and this lever is activated by a simple servo. Find and see the result on video here ...............

How to make this.

We mount on the plastic lid of the spraycan the command ,including the servo,that way when we have to replace the empty can, nothing but the can has to be replaced.

What do we need .

Two thin metal pieces of 4 x7 cm.( 2' x 3,5' ) We screw these at two opposit sides of the lid.

To have a good fix of the lid to the can we use an attachement ring as on the photo.

Here the lid is well fixed to the can.

The lid is prepared by drilling two holes in it. One to have acces to the push button ( the sprayer button) and one to have an output for the nozzle.

We need a lever , i found an usefull one , this is the sort of lever used to keep a cubboard door open .

We cut that in to two parts

Here we have a lever and a piece that will push the spray button.

On top of the lid we fix a piece of plastic or wood that is somewhat larger than the lid

Both are fixed on top of the lid.

The plastic piece is mounted at the opposit side of the nozzle. Clearly visible is how the lever is mounted.

Furthermore we need a small metal piece to fix the servo

Mounted on the servo.

Screwed on the lid and holding the servo

The part sticking out at the rear of the lid, is to fix the whole on the upper ring of the frame.

On the right the original nozzle , i replace that with the extended nozzle to bring the jet into the opening of the large data port of the robot.

Finished.
