I am looking to build an app that runs on a Raspberry Pi in full screen mode. I have already tried JavaFX and swing based app and the performance is really bad.
Before I jump on to SDL(http://www.libsdl.org/) i want to check and see if anyone has successfully build apps using the TideSDK on the PI.
Appreciate your insights on the challenges
You have to give chance to Qt

I have installed Alexa Voice Service (AVS) Device SDK on a Raspberry Pi.
I want to use smart home to turn on a led on my raspberry pi via the Alexa command.
To do this, I followed the following tutorial: https://developer.amazon.com/en-US/blogs/alexa/device-makers/2020/04/create-a-sample-alexa-built-in-disco-ball-with-smart-home-for-av
When I ask Alexa to turn on my led, the answer is "this feature is only supported by Alexa integrated devices".
I wait for Alexa to execute my request.
Is it really impossible to use this feature until the device is certified? Or have I done something wrong?
Thank you very much in advance for your help!
I have a Google Nest and a Raspberry Pi. I would like to be able to send commands from the Raspberry to the Google Nest. I have done some research and I have found ways to control the rpi with the Google Nest but not the other way around. Any clue would be helpful Thanks!
EDIT: I think Google Nest may not be the target but the google home app. In the end I want to be able to do something like this: rpi sends request => light device registered in my google home app opens/closes.
You can target the Google Nest using the Smart Device Management API.
However, there are currently only a few traits supported for controlling the Nest, specifically targeting the on-board camera.
I have been experimenting with home home automation and want to turn my raspberry pi 3 into a hub not something my devices manually connect to e.g from the gpio pins. In many unsuccessful attempts I have tried OpenHab. I would like to mount a touchscreen with a GUI so I can e.g turn the lights on from this control panel instead of via phone or other hubs available like Google Home. If anyone knows how I might do this it will be much appreciated.
It seems like home-assistant with floorplan would work for this. It takes a little bit of configuring but well worth it.
I want to create a game console with my Raspberry Pi and create my own game with an SD Card. Do I need an OS loaded with games or can I insert various SD Cards with different games?
In order to use the Raspberry Pi as a retro gaming console you will have to set it up. Go to the RetroPie Download page and choose the appropriate download for your version of your Raspberry Pi. The go to the RetroPi first installation page and follow the directions. After you complete that you will have to move your roms to the Raspberry pi into the /RetroPie/roms folder on the SD card. I use a Raspberry Pi for classic gaming and I love it.
I think there is some confusion here.
RetroPi IS technically the OS. You then "add" games to it.
If you want to create your own games then you have plenty of options.
You can technically create your own games and export them as NES games to be read by the NES emulator. This is very difficult and requires you to use tools that might be out of scope for beginners. The advantage is that you can put them in eprom chips and play them on an actual NES.
I would instead try to create a game using something like PyGame and play them on a RaspberryPi. Yo uwon't need RetroPi for something like this. Instead you'd need an OS like Raspbian
Yes definately. A raspberry pi without an operating system will not do anything. Its like asking a human to function without a brain. You should check out the retropie project. Its an operating system for the raspberry pi that lets you install roms and play the. You can even use controllers such as a ps3 controller.
Retropie
Head to RetroPie to download the image to your computer. Then, flash it on to the MicroSD with either Win32DiskImager on Windows or RPI-sd card builder on a Mac.
Have any other questions I can help with?
I'm trying to run javafx8 application on raspberry pi model B. but keyboard input & mouse motions are seems bit slow. as a example I did it with one textfield on raspberry pi. when I typing to textfeild there is a delay. tableview also same. when I click on a raw. there is a delay between mouse click and selection. I read some blogs on internet that oraclejvm's performances are great on raspberry pi. Is it possible to run javafx controls without delay on raspberry pi? I done couple of optimization on raspberry pi. is it problem with javafx8 or raspberry pi performance?
As you are probably aware the pi does not like graphics very much. I have had the same problems (with swing rather than javafx). This can happen for multiple reasons. First check your OS version. I assume that your using raspbian which had a soft float version for a while. The armel version is way slower particularly in these areas. I would run apt-get upgrade and update first and if the problem persisted, download the latest version of the OS. You are correct that oracle jvm performance is quite good on the pi so the issue is likely to do with your particular setup.
