nodeclock is a node.js based distributed sports timer

originally designed for bouldering competitions

Installation procedure (Debian/Ubuntu/Raspbian)

Login in to a console as user pi and then execute

sudo apt-get update
sudo apt-get install nodejs npm git
sudo npm install --global https://github.com/baycom/nodeclock.git
sudo cp /usr/local/lib/node_modules/nodeclock/dist/nodeclock.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable nodeclock
sudo systemctl start nodeclock

Now you have installed the nodeclock service and you can point your local browser to http://localhost/manage If you know the ip address or the network name of the nodeclock system you should be able to access the Manage page from everywhere you like.

To update nodeclock simply call the install command again:

sudo npm install --global https://github.com/baycom/nodeclock.git

On a Raspbian system you might want to start Chromium in fullscreen mode on startup:

sudo apt-get install --no-install-recommends xserver-xorg xinit
sudo apt-get install realvnc-vnc-server raspberrypi-ui-mods chromium-browser
mkdir -p ~/.config/autostart/
cp /usr/local/lib/node_modules/nodeclock/dist/chromium-browser.desktop ~/.config/autostart/

It also makes sense switching off screen blanking:

update the /etc/lightdm/lightdm.conf file and add in the [SeatDefaults] section the following command:

[SeatDefaults]
xserver-command=X -s 0 -dpms

You can use the nano editor:

sudo nano /etc/lightdm/lightdm.conf

After all you may want to disable the syslog daemon to prevent your SD card from being worn out:

sudo systemctl stop rsyslog
sudo systemctl disable rsyslog

If you need the audio to be sent to the 3,5mm headphone jack follow [these instructions] (https://www.raspberrypi.org/documentation/configuration/audio-config.md)
