Re: Mini-ITX Motherboard

Maybe that could be a Pi buy option. Supplied without connectors for those using it in an embedded project.

Re: Mini-ITX Motherboard

I just think it's a pity to go to all the trouble of a custom board and then just replicate the rats nest of cables on the inside.
If I was permanently placing a Pi in my own project I would de-solder the connectors and have fixed connections.

Re: Mini-ITX Motherboard

I think it's a nice idea but it's a pity their design requires so many internal cables within the mini-ITX case. I was thinking of something along these lines for a car pc but I don't like the idea of vibration and all those connections. I suppose it was a lot more design work to route the lines fro...

Re: Using RPi as a Standard Robotics Interface

Since we have now heard that we will be able to run the debian variant of ROS on the Pi this is looking very acheivable.

You could use the Robotic Operating System and have the raspberry pi as subnodes. Each RasPi controlling a motor or sensor cluster

Re: Low Cost Vision System

GPGPU sounds like a winner. The camera modules mentioned plug into the GPGPU don't they?
Is anyone familiar with GPGPU programming and could recommend an introduction textbook? Could anyone make a judgement on how difficult it would be to do?

Re: UAV

I also intend to build a uav.
However I will be using the Raspberry Pi for image processing for obstacle avoidance.
Mine will be fixed wing.
Probably a reverse delta wing similar to some of the Lippisch WIG craft.

This will be used to study obstacle avoidance.
