Re: Mother-Daughter Pi's?

WOW!! Once again this community is amazingly helpful!! Thank you. Regarding the post by "Herman" and "ejolson", the "cluster" looked very interesting. At this stage a couple of intended functions were being controlled by a Pi2 and Pi3 but that could be easily changed. I'll also do some research on t...

Mother-Daughter Pi's?

I'm starting an ambitious robotics project and I'm seeking recommendations/guidance for one aspect of this project. I'll have several Pi's controlling various functions such as motors and servos. Other Pi's will be reading sensors. I'd like to have one Pi that takes input and based on that input ins...

Re: Raspberry Pi Desktop for PC versus Pi3 Raspbian

Graphics Drivers? Are there are drivers to install other than what is on the Raspbian PC desktop? If so is there a page that explains what should be installed?

Raspberry Pi Desktop for PC versus Pi3 Raspbian

I installed the Raspberry Pi desktop for PC on a former Windows machine. It was a clean install on a new hard drive. My question is more of how this desktop takes advantage of the processor and GPU? The reason for the question is from an experiment I conducted using a Minoru "3D" camera. I ran an Op...

So I typed in "pair 5C:F3:70:7D:EC:C6 "
The response I got was" Failed to pair: org.bluez.Error.AlreadyExists
If they are truly paired is there simple test to confirm?
