I Have just funded this great value 3D camera on Indeigogo :
I went for the camera only (Astra Pro) perk rather than the one with built in computer as this is scheduled for possible November delivery rather than Feb (fingers crossed they don’t have too many delays). This may provide a useful add on (in addition to Tango) for the ‘Bring me the bacon challenge’, plus it will be generally useful for my robotics research 
I am sure some of you folks might also be interested in this device for similar reasons…
Consider this the start of the project thread for working with this interesting device
regards
Al
