Idea: A movable „arm“ that allows going back, forth, left and right (movement in x and y direction) with a changeable „nose“. Make the printers inner movements visible outside of the casing.

~~Schematic for~~ the ~~electronics~~ with ~~four 555 Timers~~:

Cutting the „arm“ pieces out of Kappafix (accessible, easy to work with, strong enaugh and flexible at the same time). Gluing them together (sandwiching) for a better stability.

- ~~monostable mode~~ (~~trigger~~) for ~~„on“~~ and ~~„off“~~

~~- astable mode~~ for ~~heart beat sound~~

[[File:cutting2.jpg]]

~~- monostable mode (trigger)~~ for ~~„hell“ sound~~

The upper arm needs a „Slider“ - Something that is glued to one part of the arm holding the other (movable) part of it in place. It is important that the „Slider“ is not too tight nor too lose. It should not be too hard to push the flexible part in and it should not have too much space to the left and right at the same time.

- ~~astable mode~~ for ~~„hell“ sound (using~~ the ~~same speaker)~~

[[File:cutting3.jpg]]

The „Slider“ made of papercard glued to the longer side of the upper arm.

[[File:ReexWheel1.jpg]]

The lower (static) arm did not move back and forth - the pressure from the wheels of the printer was too low. Another single wheel had to be installed that allows the back wheels to apply more pressure on the arm. The same thing has been done in the front later on.

[[File:3erWheel.jpg]]

How can the „joint“ of the two arms move to any x/y direction? It needs wheels that are like rolling spheres. This prblem has been solved with wheels from the hardware store: they contain axle bearings that allow them to circle around their own case. Three of these wheels are enough for a stable platform.

[[File:ReexAllParts.jpg]]

Bringing the parts together with a threaded rod and nuts.

[[File:ReexCallibration.jpg]]

defining the reachable area by pushing the arms to their maximum position.

[[File:ReexPWM.jpg]]

The PWM Schematic for controlling the speed of the DC motors.

[[File:ReexPWMcase.jpg]]

The PWM module in its case with a knob to control the motor speed and a connector for a 9V DC power supply that works with 220V AC from a common power plug.

[[File:ReexHbridge.jpg]]

Bringing the parts together with a threaded rod and nutsH-Bridges for spinning each DC-motor back and forth.

[[File:ReexHbridgeCase.jpg]]

The „Game Pad“ in a Kappafix case.

[[File:ReexWired.jpg]]

Everything brought together and wired up.

[[File:Reexfirst.jpg]]

The first drawing..

„Self Portrait“ with and without additional stabilation.

[[File:ReexSelfieMe.jpg]]

„Self Portrait“ with knowledge of the creator.
