I have been asked (by a mate who is studying architecture) to design and build a sequencing control system for 64 solenoids that control a mixture of UV tonic and air into a manifold of pipes to be pumped around a structure for a team participating in the Luxcity Project.
Their page can be found here ( http://stajegrouparchitects.wordpress.com/), or a news article ( http://events.nzherald.co.nz/2012/luxcity/christchurch-city/christchurch), or the Luxcity event page itself (http://www.luxcity.co.nz/, as of Dec 2017, link unavailable).
The project page can be found at Electronics->Projects-> Luxcity UV Tonic Control System.
