VFD (Vacuum Florescent Display) Clock
Components are new but have been rejected from the assembly line in the electronics factory, normally due to bent pins and other mild deficiencies. We saved these throw-aways and used them for the clock. The circuit boards used were custom designed and manufactured using a rapid prototyping process (CNC Machining). Three plates (boards) were specifically designed; one for holding the displays and interface button, one for the clock electronics and one for the speaker, and to act as a base for the entire clock.
