The Kodak DC200 and DC210 cameras are essentially the same except that the DC210 has a zoom lens where the DC200 does not. Though limited to about 1 megapixel, the cameras both are able to write Flashpix (.FPX) files which are considerably higher quality than the default .JPG compression built into most Kodak cameras of this era. The added circuitry to the DC210 includes a square wave oscillator used to drive an NPN transistor to facilitate in shorting signals to ground, introducing raster interference and moire based patterns. A potentiometer is used to vary the resistance between points. The ribbon cable attached to the CCD is a break-out wire than allows for more complex short circuiting to be conducted on the breadboard.
