Running logistics for technology classes in New York

By Ben Combee I work with a group called HTINK that teaches low-cost classes in New York City related to technology. This week, we're doing two classes, one on bioelectricity and one on clockwork mechanisms. The first class went very well, with the group making a bunch of low-cost ECG machines using sensors and laptops. The second class was also great, with a clock expert showing off old mechanism and explaining how clocks through history work. Related Link
