add / check bluetooth icon in desktop panel

Add a folder (e.g. .rasqberry-config) that contains config infos (e.g. number of LEDs/Qubits, GPIO pin used for LED strip, etc).
Add menu option in rasqberry-config to set and/or modify these settings.

port Quantum Coin Game to RasQberry with TFT display
see https://github.com/JanLahmann/Fun-with-Quantum#1-quantum-coin-game
Currently it uses Jupyter notebooks and Rise, which doesn't fit well to the small 4'' touchscreen

A RasQberry that is using a pre-built SD card image will be "offline" - and not be able to connect a new (local) WLAN.
A description is needed how to re-gain access to the RasQberry, using the touch display only (and no ssh access, etc).

The Raspberry Tie 5 & 16 demos need to be configured to work while the raspberry pi is offline.

hi Jan.I have problem to the rasqberry automatic setup.https://github.com/JanLahmann/RasQberry The hat sense line is not activated when I do the automatic setups on this link. When I install it manually, I add it into the dtoverlay = rpi-sense config.txt file, then it work. I guess it throws a lot of things into the config file in auto setup and doesn't see or open because the files are conflicting

config-new.txt

add airplane mode that disables all WLAN/bluetooth/etc transmission

Starting point might be:
https://raspberrytips.com/disable-wifi-raspberry-pi/

during the installation procedure, bluetooth apparently becomes broken.
Identify where this happens and if possible resolve this issue so that bluetooth can be used (BT keyboard, etc)

New demos can be made available through desktop icons.
Currently the *.desktop files are copied only during initial setup (do_rasqberry_enable_desktop_vnc() in rasqberry-config).
This needs to be changed in order to add new desktop icons (and new quantum demos) automatically, as they become available in the RasQberry GitHub repo.

There seems to be a regression that prevents from building (installing) retworkx, which is a prerequisite for qiskit-aer.

  ERROR: Failed building wheel for retworkx
Failed to build retworkx

Cleanup code
simplify raspberry-config and other scripts, etc
create subdirectories to artwork, scripts, config files, etc

add "standard" WLAN config (guest WLAN)
check if connected to LAN/WLAN, if not create WLAN AP so that incoming connection is possible for further configuration.

Currently, the RasQ-LED demo can only be started from touch screen desktop.
Thus, it cannot be used on a system without a touch display.
Add an option to start this demo in rasqberry-config.

install times could be significantly reduced if binary whl files for retworkx and qiskit-aer would be available on piwheels.org.
See https://www.piwheels.org/project/retworkx/ and https://www.piwheels.org/project/qiskit-aer/

detect if TFT display or SenseHAT are attached
detect which TFT display model is attached
enable (and/or autostart) corresponding demos for display or SenseHAT

Starting points might be:
Detect HDMI display: tvservice -s -n -l 
Detect SenseHAT: /proc/device-tree/hat/

remove Qiskit 0.25.4 from rasqbery-config
keep Qiskit 0.25 (which will install the latest release in 0.25)

provide option to attach an external HDMI display (in addition to the TFT touch display)
Displays (4'' TFT and external display) should be mirrored

port GHZ Game to RasQberry with TFT display
see https://github.com/JanLahmann/Fun-with-Quantum#4-ghz-game-under-development
Currently it uses Jupyter notebooks and Rise, which doesn't fit well to the small 4'' touchscreen

rasqberry-config option "bloch autostart"requires several reboots and then manually selecting this menu option again.
This reboot cycle should be automated (using crontab and @reboot statements; similar to the SenseHAT setup)

Add an (orchestration) application that get auto started when booting with SenseHAT attached.
This app let's then choose which demos to start (Raspberry-Tie or Qrasp).
After finishing the demo, control returns to that orchestration app.

Splash Screen instead of boot log messages

While Qiskit installs on the Raspberry, it would be good to make sure it also executes correctly.
Some of the Qiskit elements have regression tests.
These need to be executed on Raspberry and the output analysed.

adding a pre-installed / pre-configured RasQberry SD card image to the Raspberry Pi Imager, https://www.raspberrypi.org/software/

per default, two VNC screens should be made available:

1. mirror of the 4'' touch display
2. full HD virtual desktop that can be used for demos that require a higher resolution than the 4'' display can provide

Disable chromium fullscreen message.
See: https://www.reddit.com/r/Agario/comments/4aj631/tip_how_to_remove_the_full_screen_message_on/

I was connected the 4 inch screen to the Raspberry PI, the pins necessary for the LEDs to work are closed. Where do we attach the pins, how do we overcome this problem?

create desktop icon to access https://github.com/JanLahmann/Fun-with-Quantum (usable via VNC)

Currently the API Token is stored in multiple locations. This should be changed to just one.

I found 12 led ring and bought them.how do i connect this to raspberry. Could you tell and show us step by step how to connect with visuals?and what is the run command?

3D model provides new option with closed backplane (i.e. no display) and mount for Raspberry Pi Zero.
"display" will be the LED ring with 12 LEDs.
Define and implement a standard demo (maybe similar to Raspberry-Tie) for this setup.

create menu for touch display
to select demos, key settings, etc

develop and implement concept for RasQberry with SenseHAT

what quantum demos to use
how to control the system with the joystick (select/start/stop the demos; shutdown RasQberry)
...

see. https://qiskit.slack.com/archives/C017SC2JS6L/p1603258234011600

Could you please add a hint how to get the "IBM Q Experience access token" to be entered in rasqberry-config?

enable nightly regression tests for Qiskit install
with email notification in case of issues/failures

evaluate if Kaleidoscope would fit RasQberry.
If yes, add Kaleidoscope

design & implement a twitter monitor app for the 4'' display

Disable under voltage warning
See: https://scribles.net/lightning-bolt-under-voltage-warning-on-raspberry-pi/

probably use ansible, similar to how https://wiki.satnogs.org/SatNOGS_Client_Setup works

Qiskit can also be installed on the 64 bit version of Raspberry Pi OS, https://downloads.raspberrypi.org/raspios_arm64/images/
Need to check if all other components work as well on 64 bit OS.
Then decide whether to make 64 bit the default for RasQberry.
