Click for detail

The microDig is a thumb-sized easily configurable hardware device that encodes upto 8 analog sensor signals to multimedia industry compatible MIDI messages with high resolution and transmits these messages 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 1500 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 microDig features a hardware hacking area to add your own sensor circuit.

Configurable It's updateable firmware v5.1 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 one of our editors. 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 in combination with a programming or analysis environment to process the sensor data.

Compatible The microDig encodes analog (0-5V) sensor signals to multimedia industry compliant MIDI messages, and transmits them using a physical MIDI interface. On the sensor input side, note the microDig's I2C capability which is one of the more common protocols used in robotics - connect upto 4 I2C devices directly to it. But you can connect many more I2C devices, since they can be daisy-chained !

Far and beyond. If you need to use the microDig further away from your MIDI setup or interface than the cable permits, use a MIDI cable extender, or go wireless with the MidAir. Check our page with other products to use with I-CubeX for 3rd-party solutions. You can also use our ExtensionCable-5 to place sensors further away.

Get it now ! It is sold as part of the microSystem. For more inputs and resolution, as well as actuator outputs, check out the Digitizer. For a thumb-sized, faster and USB-cabled version (no MIDI interface needed) with actuator outputs, check out the USB-microDig. For a thumb-sized, faster and wireless version without actuator outputs, check out the Wi-microDig.
