Hi guys, There is a new sensor ball, called "Blobo". The link of the product is below: http://www.blobo.co.uk/[^] Its SDK is free. Now I am trying to develop an application with it. There two versions of Blobo SDK. The one I use is for Win32 SDK. According to the SDK comments, it is said that I can connect to three blobos at the same time. So I am trying to connect two blobos. However it seems that connection becomes very unstable when I try to connect to more than one Blobo. Does any one here happen to develop any applications with Blobo? Do you have similar questions like mine? I really want to find some people to discuss the Blobo development together. all best wishes,
