the price is quite expensive if you ask me,
i meet the guy behind that product in particular the sensors,
i know a guy that used eyesweb for research and use the sensor of eoware but with arduino with good results, have a look at arduino if u don’t know it.
But in reality u can buy that type of sensors and they are very cheap too!
I always work with arduino and sensors from alectronic shops, and infact that sensors aren’t custom made by Eoware apart from some isolating and some little integrations.
sure, Arduino Rocks!!! i have one and extra Atmega168 to build another in a breadboard, its fancy, you can connect anything and arduino is a friend for any software, you can connect almost any sensor and extend its capabilities with other cheap chips, in my humble opinion its the best option, and works very well with vvvv…
