- Indeed, the gadget is called a Scanner, popular makes are Roboscan and Robozap,
- they consist of a color wheel (gobi), a pattern gobi and a shutter along with
- an Xenon MSR1200 lamp (1.2kW). The scanners are chained together in a bus
- network configuration, the whole lot is run by a PC (Roboscan 2032 controller
- is a PC AT) A top of the range Roboscan costs approx 8000 dollars.
-
- Something that looks more like a laser is called an Emulator, they are made
- by a nevada company, whos name escapes me at the moment.
-
- Anyone here built any disco lighting effects? I'd like to hear from you.
