Re: Maker a timer based winch/actuator system

The timer is trivial. A simple cron job will even allow you to run it at set times of day. You'll find plenty of Python / C examples online that could sort out the GPIO issues for you, which is the bulk of the work. Depending on how complex you make it, it could be a few lines of code or a few hundr...

Re: Loading Video and Slideshow onto my SD card

Omxplayer would be the best choice for the video, but I don't know if the settings would allow you to clamp the displayed video to a section of the screen... Technically all you'd need to do is launch the Omxplayer with the loop option, and launch the sideshow underneath it (since Omxplayer just wri...

Re: Wired PS3 Controller Works in Menu OR Game, Never both?

From memory, the settings you use in the emulator (when the games are running) aren't automatically saved. There's an option in one of the menus to enable saving on exit, as well as one to save the config as is.

Re: Pi 3 sudo rm issue

If you're running this within a script, and the script dies at this point due to the failure, you can use 'sudo rm -f <filename>' instead (which succeeds even if the file doesn't exist).

Re: streaming from cheap HD "sport camera" ?

I got one of the super cheap sport cameras a while ago to play around with. Supposedly 1080p (has it in the options), but only records in 720p, and the quality isn't great. BUT, and I must make this point: you could buy 16 of these cameras (that come with accessories) for the same price as a single ...

Re: Audio for Raspberry

Have you selected analog audio as the output device (left / right mouse click the speaker icon in Raspbian)?

Also, what program are you using to play audio? If you're using omxplayer, you can use command line switches to use analog audio output. VLC has the list of audio devices in one of the menus.

Regarding the messages being on the TV, do you mean while something else is on? If so, you're going to need hardware that injects text into the video stream (which may be an expensive thing to set up). Interaction with those devices will be another issue in itself...

Get a new SD card, write a new copy of Raspbian onto it, boot the Pi with it, then use a USB SD card reader, and your original card, and pull the data off. There are programs out there that will read other file system formats in Windows, but if the card has issues, you're better off with a new card ...

Keep in mind that electromechanical relays have a set number of toggles they can go through before they stop working, and you need to suppress the arcs to ensure the relay lives as long as possible. Solid state relays don't suffer from that. As for what to switch, switch whatever is convenient for y...

If you've somehow managed to download an old version of Raspbian, it won't work on the Pi3. Try downloading the latest Raspbian Jessie image, reimage the card with it, and see how that goes.
