ftPi

This is yet a preannouncement of my fischertechnik raspberry mix project.

the idea

Cheap and easy to use alternativ to the expensive fischertechnik txt controller.

what we want

Hardware

• Controlling motors (at least 4, maybe more)
• reading switches (digital read, at least 4)
• reading sensors (analog read)

Software

• flowbased Development ( Known from fischertechnik software)
• webbased controlling (eg: like rc remote , or Smartphone gyro)
• fpv mode (Support for on Board Webcam with live stream)

Used Components

Hardware

• Raspberry Pi 1 (can be newer) (Raspberry Zero @ 5$ will probably work, but without fpv/webcam)
• Arduino Motor and Stepper Head (can be stacked for more motors - 4 DC or 2 Stepper) link
• (upcomming) Arduino Servo Head (supports up to 16 servos) link

Optional

• USB Powerbank - for mobile Raspberry power supply
• 7.4 V Lipo - for motor power (you can use the powerbank instread, but that makes it a bit weak - fischertechnik requires 6/9 V for the motors)

Software

• Raspbean Wheezy (newer not tested yet)
• NodeJS as FrontEnd Server
• Python Autobahn as Backend Server
• Websocket communication
• GoJS for Programming UI
• mjpg_streamer for webcam access

Status:

• I've got the first working edition (for developer or linux gurus only) XD

TODOs:

• Upload the code
• pray for ne licence / patent problems
• write a guide
• link all stuff
• clean the code
• publish in ft community
• learn how to publish on github correctly ;)
• find someone fixing my typos

and mutch more
