Re: Get smart TV feed

Does the TV have output available to a video recorder? If yes ... does it allow the "smart" content to be recorded? Alternative approach ... are the video sources that you want available via a Kodi add-on? If yes - then you could use Kodi on RPi to provide your "smart" viewing and then run Hyperion ...

Re: MPEG2 patents expiring

If you went to a car dealer and were considering a car with a window sticker price of 22 thousand and was told that "after dealer markup, that'l be 220 thousand" would you think they were gouging, or would you just roll over and "pay the vig". But what if the dealer said it would be 22 thousand and...

Re: RPI 3 B+ rainbow screen

If not already done .... use you RPi3 to update the software on the SD card then try it in the RPi3B+

sudo apt-get update
sudo apt-get dist-upgrade

(assuming that your SD card already has Raspbian Stretch on it)

Re: Is it possible to read 10 tons digital weight scale sensor with raspberry pi ?

My reading is that "this 10 tons wight scale" means that they already have the weighing machine in use and now want to try to read it via a different mechanism (probably in addition to the existing way). If that is the case then would need to know the details of how it makes data available - or at l...

Re: Hdmi no output on pi zero w

Is your Pi0in a case?
If yes it is possible that the case is preventing the mini-HDMI connector going all of the way in.
I had that problem and resolved it by shaving some plastic from the end of the mini-HDMI connector.
