This is the first of what may become a series. On Work In Progress Night a foulaber will bring a work in progress to the lab and work on it for a few hours. Anyone interested can drop in to check it out and discuss the project, receive or give advice, or bring a similar project and work on it. There is no promise that anything will actually work, but it should be fun!!!
While the idea of putting a couple steppers on an etch a sketch to produce etch a sketch drawings seems straightforward, there are actually a number of tricky points. There is quite a bit of mechanical backlash in the sketch, meaning that the order in which you draw lines makes a lot of difference. The image processing required to generate a scene which can be drawn in a single line from a picture is also interesting.

Cost: Free, although pass-the-hat style donations to support the lab are encouraged.
