Re: How to use relative path to my script...

Generally, using relative paths are preferred unless you're 100% sure the file system the script is being copied to is exactly the same. You can find a nice description in the wikipedia article for more information: https://en.wikipedia.org/wiki/Path_(computing)

Uh-huh. :roll:
I have done quite a bit of research but I am lost at the moment as I am not sure how to go about using OpenCV to detect a colour and then return a value to my programme.
Let's see what you've accomplished. Post your code.

Re: Processing updated

They now have a helpful installation/usage guide at Processing for Pi, too.

I was happy to see that too. Processing on an RPi was kind of "iffy" for awhile but it's getting better with every release.

Re: HELP! power outages wiping SD cards

No worries. It was a bit of a generic "one size doesn't fit all" statement.

Re: Automation and Control

Instead of looping and sleeping, how about using interrupts? Not sure why you'd want to do this. Adding the necessary masking and detection adds more complexity to the programming. I mean, sure, you could, but your problem domain is simpler. Interrupts I consider better for events that are asynchro...

Re: HELP! power outages wiping SD cards

The problem of sd-cards that can corrupt themselves when turning power to them off suddenly isn't solvable by doing something with the PI. Actually the problem can be mitigated somewhat by using onboard power, such as a lithium battery. 1.8vdc is enough to power an SD card generally speaking. Addin...

Re: HELP! power outages wiping SD cards

A probably cheaper solution is to research one of the methods of having a read-only SD card. The problem with this is that you have no where to write the logs, etc. I think, although I haven't tried it, one can create a Read only SD card but have to direct any write operations to a USB device. My u...

Re: HELP! power outages wiping SD cards

When testing the units for power cuts and outages, the power outage is removing the image from the SD card meaning we have to re-image. Um, no. It doesn't remove the image. As mentioned, it may corrupt it. If you want "fail proof" corruption protection then you'll need a ROM with self-boot code add...

There's still the possibility of incompatibility with dbus but you'll have the bluez version you want to test it with.

Nope, not without using a stacking header from here: https://www.adafruit.com/product/1979 You may have to get a couple and stack them to clear the fan. Remember to use longer standoffs to secure the sensor hat to the RPi board.
