      The large flipdot module consists of seven 1x7 flipdot strips in an active bipolar matrix. Each dot occupies 0.6" square. Rows and columns have both a MOSFET based high- and low-side driver connected to the power supply pins. The module allows only for one dot to be flipped at one time, but it can flip any dot in 550µs.

      The module is designed such that multiple modules can be combined in a larger setup without borders or inter-module gaps. The 7x7 module works with the controllers below.

    Controllers

    • Active Flipper Control - Cascade-able x16 Controller

      625x450 625x450
      2500x1800 2500x1800

      The Active Flipper Controller uses a small ARM micro-controller with serial, SPI and I2C communication channels. The flipdot module, either large or small, is controlled through the two 16pin headers at the bottom. The controller automatically adjusts the drive-strength and timing depending the supplied voltage.

      The controller accepts high-level commands on the communication channels to set dots, lines, characters, patterns and configuration settings. The commands are automatically forwarded to the next controller and 16 controllers may be cascaded and controlled through one single communication channel, while retaining the ability to address each controller/flipdot separately.

      Cascaded controllers operate independently and each connected flipdot module can operate at the same speed. That means that 16 cascaded controllers can update all 16 connected flipdot modules at a maximum of 33 frames per second (or more than 26000 flips per second in total).

      A 3.3V serial console is provided for debugging purposes and manual configuration, using a standard connector pinout commonly used in serial-to-USB breakout boards (like Adafruit's FTDI-friend and Sparkfun's FTDI breakout). Also, firmware debugging is possible on the provided SWD connector.

    • Active Flipper Control - Passive Controller

      600x350 600x350
      2400x1400 2400x1400

      The Passive Active Flipper Controller is a scaled down controller and only provides a basic interface to the large and small flipdot modules. It consists of a set of de-multiplexers and buffers to control the 28 flipdot module's control lines. The de-multiplexers ensure that no short-circuit can arise on the bipolar matrix of the flipdot module. A pulse-shaper is used to ensure the proper current through the flipdot coils.

      No timing or measurements are performed on the passive controller and all intelligence must be supplied by the user. The user drives the X/Y selection lines and controls the pulse/charge cycle on demand.

    • Active Flipper Control - Differential Input Controller

      flipperctl-small-design

      In development.

      The Active Flipper Control with differential inputs is optimized to have as few external connections as possible. The only connections are power and differential input. The controller accepts high-level commands to flip dots and patterns as well as optional configuration data.

      The Communication is based on RS485 with 3.3V signaling and a 3-bit address can be set with dip-switches for operating the differential input on a bus-structure.

      The controller measures the supply voltage and actively controls the timing to flip any dots, ensuring proper operation under a variety of operating conditions.

    • Active Flipper Control - Master x64 Controller

      flipperctl-6x4-design

      In development.

      The Master x64 controller controls up to 64 differential input controllers. There are eight buses driving up to eight differential input controllers, including power supply. The Master x64 controller incorporates both 10/100 Ethernet (auto speed, auto MDI/MDI-X) and a galvanic isolated RS485 bus (with termination switches). The RS485 bus uses the same CAT5 cabling as Ethernet and comprises an A/B-bus structure controlled by straight/crossed cabling to create the proper T-shaped RS485 bus.

      The Master x64 controller can operate as a bridge between Ethernet and RS485, where it may become a RS485 master controller, driving up to 31 RS485 slaves on the same bus. A total of 2048 flipdot modules can be controlled in this fashion without compromising update speed. Each and every connected flipdot module can operate at 30 frames/s update speed.

      A broad variety of configurations is supported such as 8x8, 7x9(+1), 6x10(+4), 5x12(+4), 4x16, 3x21(+1), 2x32, 1x64 and "just a bunch of modules". Upstream control from a PC is free to define any applicable configuration.

    • x64 Wall Panel

      mech-x64-design

      In development.

      A 3mm aluminium backplane cut-out to support 64 large 7x7 modules with differential input controllers and a master x64 controller. Multiple of these wall panels may be combined to create even larger walls. The backplane adds support holes for mounting into a larger frame or backing wall.

      Alternatively, the backplane can be delivered for small 7x7 modules and configurations other than 8x8, like 2x32 and 4x16.
