Re: Cloud robotics demo code (now with actual code and links to BBC and FT)

Are you still planning on posting your code?

I can offer my github repo as a landing place if you want. I have started some similar projects for the Rover. One of which is to drive it via a android app.

Re: issues with PI SD Card .. Failing to boot... and a Heartbeat between PI and Arduino

I think I have an alternative solution. We can do a heartbeat over the I2C interface used to send cmds from PI -> Arduino. It would just be a command that is sent every 30 sec or 1 min. It refreshes a global on the Arduino side. When the Arduino sets the power down, it waits for X secs and if the gl...

Re: Forward-thinking: Jessie or Stretch? Python 2 or Python 3?

Python as the outside interface into the rover would be great, a way to program the rover over ethernet or BLE to tell it to do things. (Move forward, take a picture, video, etc..). Maybe even a graphical interface for real young coders (kinda like turtle). We could even have an interface in the 'sp...

Re: Raspberry Pi doesn't start

This does not sound like it is recoverable. What size SD card are you using? I would use a min of 16GB now. As the base image will fit ina 8 GB part but once you start adding things and updating (it has to d/l the updates and then apply them) it can eat up the space. I had an issue of runnging out o...

Installing Webmin -- on Rover

I am using Webmin running on the PI to configure network access (Samba, NFS, etc..) as well as manage installed packages. It has a great web interface that lets you update packages, install new ones, manage servers, etc.. Easy to install on the PI. apt-get (Debian/Ubuntu/Mint) By adding the webmin r...

Re: pin mapping between Raspberry Pi and main board connector?

Great!!

I will look at this and create some docs to detail the interface.

Will post a link to them when I am done. Will put them into one of the repos I have created on github or maybe make a new one for docs??

Re: issues with PI SD Card .. Failing to boot... and a Heartbeat between PI and Arduino

The heartbeat is just a kernel module, this could be a standalone module or incorporated into another one. It is no big deal. Have done it multiple times in the past. If you do not want to always have to run your code as sudo or some other such nonsense you have to start lookign at kernel modules. B...

Re: pin mapping between Raspberry Pi and main board connector?

Kevin,

The community really needs these specs.

If it will help I can take a schematic and create a doc from it detailing the pinout, etc..

Re: Forward-thinking: Jessie or Stretch? Python 2 or Python 3?

I propose C and kernel drivers and actual applications.

Python is good and all but it does not get you the speed and flexibility of having kernel level code.
