The Wi-miniDig is a palm-sized hardware device that encodes upto 8 analog voltage signals (such as generated by sensors) to multimedia industry compliant MIDI messages with high resolution in real-time. It transmits these messages wirelessly to your computer, much faster than MIDI speed, using Bluetooth, which is a common and reliable protocol. It allows for the use of multiple Wi-miniDig units simultaneously so it's easy to make a wireless sensor network. It's firmware v4.5 enables it to operate in both stand alone mode (sensor data is processed before it is transmitted) as well as host mode (raw sensor data is transmitted). Stand alone mode includes various sensor processing and mapping features such as gesture recognition that can be conveniently configured using one of our editors. It is sold as part of the Wi-miniSystem. For a wired version with MIDI cable, check out the miniDig. For more inputs and resolution as well as the ability to control actuators, check out the Digitizer.
