A prop from Live Escape Grenoble using PyQt5.
A real word prop, we have created a fortune teller table with a cowhide top and 36 flashable alphanum characters with powerful LEDs, this prop (named alphabet in French at the time) is powered by a Raspberry Pi; the game master send a clue which is spelled character LEDs. Some flashing effects are available to scare players.
Players must place a Tarot card in the correct place on the table to win the challenge that opens the door to the lounge.
This is a good example of RFID shield.
The LEDs are wired in a matrix:
SRD relays have been replaced with transistors to be silent and reliable:
We use a MIFARE RFID-RC522 module:
http://wiki.sunfounder.cc/index.php?title=Mifare_RC522_Module_RFID_Reader
| RC522 pin | Raspberry Pi 3 pin name |
|---|---|
| SDA | GPIO8 |
| SCK | GPIO11 |
| MOSI | GPIO10 |
| MISO | GPIO9 |
| IRQ | Not connected |
| GND | GND |
| RST | GPIO25 |
| 3.3V | 3V3 |
We have hacked MFRC522.py from MFRC522-python for GPIO mode and due to a trange behavior (when a card is present: it loops detected/not detected), we need to read the NFC tag twice.
This prop was created before PyProps library was released so there is no dependencies with PyProps.
You will have to install following Python packages:
$ pip3 install paho-mqtt
$ pip3 install PyYAML
$ sudo apt-get update
$ sudo apt-get install qt5-default pyqt5-dev pyqt5-dev-tools- enable SPI in raspi-config
- check:
$ lsmod | grep spi
spidev 16384 0
spi_bcm2835 16384 0- install python library
$ sudo apt-get update
$ sudo apt-get upgrade- download and install SPI-Py
$ cd ~
$ git clone https://github.com/lthiery/SPI-Py.git
$ cd ~/SPI-Py
$ sudo python3 setup.py install- test reading a tag
$ sudo python Read.pyStart main.py script in /home/pi/Room/Props/PyProps/QtProp/FortuneTellerTableProp/:

The command to relaunch the prop is :
$ ps aux | grep python | grep -v "grep python" | grep FortuneTellerTableProp/main.py | awk '{print $2}' | xargs kill -9 && screen -d -m python3 /home/pi/Room/Props/PyProps/QtProp/FortuneTellerTableProp/main.py -s %BROKER%Fortune Teller Table Prop as a prop for xcape.io Room
This prop is used as a prop for xcape.io Room software.
Commands are in French; look at the code in AlphabetApp.performAction() method.
