The Kodak DC215 is an upgrade to the DC210/200 cameras. Though still limited to about 1 megapixel, the camera is slightly sharper than it’s immediate predecessors and still 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 DC215 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. A few additional wires attached to the PCB allow for more complex short circuiting to be conducted on the breadboard.
