A HUGE hardware and software project is installed during 2015 at the railway station of Mons in Belgium.

Fred Sapey-Triomphe installed a 168m² LED screen that shows videos and interacts with the passengers flow with passive sensors.

YGDES/Yann Guidon designed and installed all the electronics and software (C/VHDL). A special motherboard for the WizYasep extends its features to provide 20 asynchronous outputs and sequence the power of 4 blocks of PSUs. All video data are streamed through a 100Mbps Ethernet network.

The installation is no more since january 2016 but it remains an incredible memory ! It saw the WizYasep's first deployment and we matured many techniques that are being reused for other projects. Thanks to everybody who supported us !

It's an incredible amount of work but everytime I visit it, I see people taking selfies. It's rewarding when your work makes people cheer and smile and "wow" :-)
