Through the years I have learned to improvise in the design and construction of teaching equipment. Often a commercially offered solution is unreasonably expensive, unsuitable, or simply unavailable. I have built extracellular electrodes, suction electrodes, and a cricket locomotion tracker. I am very interested in finding inexpensive solutions to teaching laboratory biology and neuroscience at the high school and college level. Some of the resources I have collected are gathered together here for those who would like to start exploring the world of homemade, shoestring biology.
