Not all of us have CNC machines, laser cutters and 3D printers, and I’ll bet most of us didn’t start out that well equipped. The low-cost drawing machine that [jegatheesan] made for his daughter ...

A raster drawing from a scanner can be converted to a vector format for later use, such as finite-element analysis. Raster drawings can be compressed to store in less disk space than the same drawing ...

Stepper motors are great for projects that require accurate control of motion. 3D printers, CNC machines and plotters are often built using these useful devices. [InventorArtist] built a stepper-based ...

With the advent and proliferation of tablets, using a pen to annotate or even sketch is becoming more and more useful, if not necessary. Enter the Space Pen. Now, you can sketch or annotate 3D models ...

Researchers have developed an automatic drawing machine that uses pens and pencils to draw metamaterials -- artificially engineered composite materials that derive their properties from patterned ...
