```
|
|
|
|
* connect the button and LED to pins as shown in `buzzctrl.sh`
|
|
* create a file "secret.txt" containing the http://user:pass@10.1.1.xx part of the URL
|
|
* adapt the URL in buzzctrl.sh
|
|
* adapt spaceapi URL in spacestatus.py
|
|
* put .mp4 videos into ~pi/ and they will show when your hackerspace is open you can add videos and they will be taken into account automatically
|
|
|
|
when booting, the button led uses morsecode to send the low byte of the IP adress in decimal
|
|
|
|
`phone_notification_client.sh` communicates with pidor's `doorbuzz_wrapper.sh` to command the flash light

# new: using redis to manage the 60 led circle
|
|
|
|
```
|
|
sudo apt-get install python-pip redis-server python-redis
|
|
```
|
|
|
|
* redi.sh comes from here: https://github.com/crypt1d/redi.sh
|
|
|
|
```
|
|
cd ~
|
|
git clone https://github.com/jgarff/rpi_ws281x.git
|

cd rpi_ws281x
|

sudo apt-get install scons swig python-dev
|

# setup watchdog
|
|
|
|
```
|
|
sudo modprobe bcm2708_wdog
|
|
echo "bcm2708_wdog" | sudo tee -a /etc/modules
|
|
|
|
|
|
sudo apt-get install watchdog
|
|
sudo update-rc.d watchdog defaults
|
|
|
|
sudo sed -i 's/#\(watchdog-device\)/\1/
|
|
s/#\(max-load-1\s\)/\1/
|
|
' /etc/watchdog.conf
|
|
|
|
sudo service watchdog start
|
|
```
|
|
|
|
|
|
Note: `projectionscreen.sh` is a standalone program called remotely by pidor because pidor knows the IP adress of the projector but doorbuzz has the RF remote connected.
|
|
The remote command works with ssh, so install pidor's root pub key into `~pi/.ssh/authorized_keys`

|
====
|
|
|
|
* create a config file
|
|
* put more of the hardcoded values from code into parameters
|
|
* make code resilient against missing commands (e.g. gpio not in PATH)
|
|
* move script to run in screen instead starting from rc.local
