Also its not too much about electronics, that has not changed since the first project (bechele 1) because it consists of cheap ready made parts. At prices of about 4 euro for a PCA9685 PWM controller direct form china, self made simply does not make sense. However you need to know the used parts and how to wire up, therefore the description here:<\/p>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-luminous-vivid-orange-color\">Related links:<\/mark><\/strong><br><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\"><a href=\"https:\/\/bechele.de\/?page_id=199\">Project main wiring<\/a><br><a href=\"https:\/\/bechele.de\/?page_id=1083\">Servo Board Chaining<\/a><br><a href=\"https:\/\/bechele.de\/?page_id=202\">The Joy Stick<\/a><\/mark><\/strong><\/p>\n\n\n\n<p>The Hardware of the project consists of the following parts:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Raspberry Pi 3 Modell B, Raspberry Pi 1B or <a href=\"http:\/\/www.orangepi.org\/orangepipc\/\"><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">OrangePi PC<\/mark><\/strong><\/a><\/li>\n\n\n\n<li>16 channel PWM servo controller(s) from Duinofun, DeekRobot or Adafruit based on chip PCA9685<br>If you need more than one PCA9685 PWM PCB, see the following link how to use several:  <a href=\"https:\/\/bechele.de\/?page_id=1083\"><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">Servo Board Chaining<\/mark><\/strong><\/a><\/li>\n\n\n\n<li>Here you can find more about how to wire the recommended components: <a href=\"https:\/\/bechele.de\/?page_id=199\"><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">Project main wiring<\/mark><\/strong><\/a><\/li>\n\n\n\n<li>Analogue (or digital) model building servos &#8211; for example&nbsp; SG90, MG90 or many other types.<\/li>\n\n\n\n<li>Plug based power supplies 5V 1x for Rasperry Pi and 1x for each servo PCB (The partition of the power supplies prevents of electrical disturbance and is actually mandatory) You may also use a big 5V power supply for several PWM servo PCBs. But make sure each board has its own power line to the power supply. I noticed, that chaining the servo power through the Extension pins leads to problems with electric disturbances, that caused the PWM PCBs to work unreliable.<\/li>\n\n\n\n<li><a href=\"https:\/\/bechele.de\/?page_id=202\"><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">The joy stick<\/mark><\/strong><\/a> (self made) with data processing via Arduino Micro Pro and transfer via serial interface to the Raspberry Pi.

Just set up you audio mixer in use (alsamixer) accordingly. <\/li>\n<\/ul>\n\n\n\n<p>I recommend to use one of my 3D printable eye mechanics, since the time to build them is much less than making your
