Wi-microDig v6.3x/6.0x (obsolete)
>> Wi-microSystem || Application info || Technical specs || Driver download
The Wi-microDig is a thumb-sized easily configurable hardware device that encodes upto 8 analog sensor signals to multimedia industry compatible messages with high resolution and transmits these messages wirelessly to a computer in real-time for analysis and/or control purposes.
Sensitive in real-time
It has 8 inputs of each 10 bits resolution (1024 steps of each 4.9 mV) that can sample at upto almost 1000 Hz with milliseconds latency to capture even the finest gestures and movements. Use it conveniently with our sensors to create your interactive installation, ultimate controller, .. For hardware hackers, the Wi-microDig features a hardware hacking area to add your own sensor circuit.
Wireless
The wireless transmission complies with the Bluetooth v2.0 standard (using the WIDCOMM or Microsoft Bluetooth protocol stack, but not the Bluesoleil stack), which is a common and reliable protocol that is legal to use anywhere in the world, and at 115.2 kbps much faster than MIDI speed at 31.25 kbps. The wireless range of the Wi-microDig is specified to be at most 400 meter (without obstructions), since it is a Bluetooth class 1 device ! To get the maximum range you will also need a class 1 Bluetooth interface for your computer (note that the built-in Bluetooth interface in Apple computers is class 2 with a much lower range). A Bluetooth interface allows for the use of upto 7 Wi-microDig units simultaneously so it's possible to make a wireless sensor network.
Configurable
It's updateable
firmware v6.3x enables it to operate in both "standalone" mode (sensor data is processed before it is transmitted) as well as host mode (raw sensor data is transmitted). Standalone mode includes various sensor processing and mapping features such as gesture recognition that can be conveniently configured using our EditorX software. Configure it with the editor and it will remember the settings after power down. If you need raw sensor data or if you need more sensor mapping or analysis complexity, use it in host mode with our Link software or in combination with a programming or analysis environment to process the sensor data.
Compatible
Even though it encodes analog (0-5V) sensor signals to multimedia industry compliant MIDI messages, you don't need a MIDI interface to receive them. Because the Wi-microDig uses Bluetooth, the MIDI messages appear on the computer at a virtual serial port (called "COM" port on a Windows computer). Our editor software takes the data from there and allows you to route the data in a variety of ways to the software or device of your choice. Once configured using our EditorX software you can use the Wi-microDig with software that communicates directly with devices through the virtual serial port. Our Link software has even more capabilities. Or you can use our Connect application to map the data to/from the serial port from/to a virtual MIDI port or an OSC port.
But wait, there is more ... !
Actuators
Control different types of actuators: regular binary "on/off" actuators, PWM actuators such as RC servos or digital (I2C) actuators. The pins in the middle row of the input/output connector can be configured as output pins for controlling (binary or PWM) actuators. In order to use these output pins, you may have to change the position of one pin in the housing of the actuator plug so that it inserts into the middle row of the input/output connector. The pins configured for output are for control only. To drive an actuator you need to install a transistor or similar, that is controlled by the actuator output, to enable/disable power supplied to the actuator from the 5V power.
I2C
The Wi-microDig's I2C capability makes it compatible with one of the more common bi-directional communications protocols used in robotics for sensors and actuators - connect upto 4 I2C devices (sensor or actuators) directly to it. It's possible to connect more by daisy-chaining them.
Get it now !
It is sold as part of the Wi-microSystem. To get the maximum range you will need a class 1 Bluetooth interface. The BluetoothAdapter has both these features. Want to use the power grid instead of batteries ? Use the Wi-microGlobalAdapter.
For a thumb-sized, USB-cabled version (no MIDI interface needed) with actuator outputs, check out the USB-microDig, that, together with the USB-microMIDICable can also send MIDI messages directly to your MIDI gear.
For more inputs and resolution, as well as actuator outputs,
check out the Digitizer.
