Reader Viesturs K. submitted the following on a prototype copy machine:
The purpose of this machine is to copy a black shape. On the left side is black material and table is serving as lighter material. Note it works by recognizing a fixed reflection value.
I am a carpenter and I am building a prototype of a carving copy machine. The Next test is to recognize ~6 darkness levels and depending on thecolor scanned, the cutting tool (in this case marker) will cut the programmed distance in the Z axis. For example, black/white pictures would be cut out with terrain.
Of course it can serve as printer/plotter as well, but I need to finish the program for that.
