The motor control aspect of the project was very straightforward. The idea was to create a customised rotating prism display system for a high end retail outlet in London.
The unit required synchronisation of all 3 prisms and also needed to be programmable to change the times and angles displayed. An initial specification of 5 second turn and 20 second pause every 120 degrees was received. This was specified by the final end user and was considered the optimal ratio between the columns moving and being stationary to provide the required level of customer intrigue.
