    The SCN5 or SCN6 actuators are the most common and best known actuators for a commercial or private simulator. They are build in in many commercial and proffesional simulators. They are tested by many professional racers and have a big press response. They are most common and you are always taken seriosly if you go with this setup. If you own such actuators X-Sim will only pass through the data to them and they will do the rest as in proffesional tested simulators. X-Sim itself offers a wide range of different setups for this actuators. Of course, you do not need them in the first steps but you will love the details if you got into it.

    The SCNx actuators are of course expensive compared to DIY actuators. However you have less setup work and the best feeling for this money. This actuators are simple to connect and need less service time. They are also very silent and usable in a normal private apartment without making the neighbour angry.

    We at X-Sim.de do not sell this expensive actuators and cannot give warranty for this devices. It is highly recommended to buy them directly at the official reseller in the world. He is informed about this forum and the members which like to get a professional device with very less money.
    In the first step you can try to get some old SCNx actuators from eBay or sometimes from this forum. Simple search for SCN5 in eBay or visit the private marketplace of this forum. Be carefully with the deals, we give no warranty for the sellers.

    Here is the link to the online shop where you can get a pair of SCN5 actuators with 100mm (standard) for around ~850$ (7/2012):

    https://miraiintertech.com/e-store/products/SCN5.html

    This is the official reseller for this product worldwide. It is not possible to contact the factory directly.
    He is very firm with a cheap delivery of this heavy devices in all countries and all the members of X-Sim have positive response with this reseller.
    You can buy SCN5 100mm or 150mm if your weight is below 90kg. Some are using the actuators with a weight of 100kg but it is recommended to look closer for the SCN6 actuators.

    Additional you may need:
    – one USB to RS485 converter per SCN5 actuator
    – the mounting parts for the SCN5 decices (same shop)
    – a ball joint with the fitting thread
    – some fitting connectors to avoid the warranty loss and the needed cables. The wiring is described in details in the hardware thread below.
    – for each SCN5 actuator you will need a power supply with 24V and 3A . If you search for a switching power supply you may get one with a bif inrush current which can destroy your actuator electronic. It is better to get transformators out of halogen light equipment or from DIY shops like pollin, reichelt or conrad electronic. Some members have also managed to find a good single power supply for two actuators.

    Please read this thread for details how yu can wire the SCN5 actuator to X-Sim.

    We support unlimited SCNx actuators connected to the PC. This means you can not only build a 2DOF racing seat, you can add a third axis some time later if you like to increase your degree of freedom.
    If you own a pair of SCN5 actuators you can build a simulator around them like many did before you. Do not think you need a plan to build such a simulator, simple build it. Start with a chair and follow the guideline of your woodcrusher sample simulator with your favorite material.

    Pololu Jrk 12v12 USB Motor Controller with Feedback


    Warning: Invalid argument supplied for foreach() in /var/www/ud09_148/html/shop/wp-content/plugins/google-language-translator/google-language-translator.php on line 473

       

       

      Overview

       

      The jrk 12v12 is a versatile, general-purpose motor controller that supports a variety of interfaces, including USB. The 6 V to 16 V operating range and high continuous output current of 12 A (30 A peak) allow this board to control many medium-sized DC brushed motors. Analog voltage and tachometer (frequency) feedback options allow quick implementation of closed-loop servo systems, and a free configuration utility (for Windows 7, Vista, or Windows XP) allows easy calibration and configuration through the USB port.

      Key improvements over competing products and earlier Pololu motor controllers with feedback include:

      • USB connectivity with emulated serial (COM) port allows direct motor control from a PC.
      • Ultrasonic PWM to eliminate switching-induced motor shaft hum or whine.
      • Robust, high-speed communication protocol with user-configurable error condition response.
      • High internal resolution (12 bits) for smooth and flexible calibration to various input and feedback devices.
      • Current sensing and limiting.
      • Reversed power protection.
      • Field-upgradeable firmware.

      Main Features of the Jrk 12v12

      • Simple bidirectional control of one DC brush motor.
      • 6 V to 16 V operating supply range.
      • 12 A maximum continuous current output (30 A peak).
      • Four communication or control options:
        • USB interface for direct connection to a PC.
        • Full-duplex, TTL-level asynchronous serial interface for direct connection to microcontrollers or other embedded controllers.
        • Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo controller.
        • 0–5 V analog voltage interface for direct connection to potentiometers and analog joysticks.
      • Two closed-loop feedback options:
        • 0–5 V analog voltage.
        • Frequency/tachometer digital input up to 2 MHz with 1 ms PID period.
        • (Open-loop control with no feedback also available.)
      • Simple configuration and calibration over USB with free configuration program (Windows 7, Vista, and Windows XP compatible).
      • Configurable parameters include:
        • PID period and PID constants (feedback tuning parameters).
        • Maximum current.
        • Maximum duty cycle.
        • Maximum acceleration.
        • Error response.
        • Input calibration (learning) for analog and RC control.
      • Optional CRC error detection eliminates communication errors caused by noise or software faults.
      • Reversed power protection.
      • Field-upgradeable firmware.
      • Optional feedback potentiometer disconnect detection.
