Just like last semester I am still very interested in crystals, crystalline growth and the way the growth can be manipulated. Currently I am experimenting with a sound proof box that I developed last semester [], crystals solutions and noises.
For this class I am not yet sure what my project will be about. I am interested in building my own crystal radio, testing different crystals with it and see what noises can be detected in the urban space as well as in the woods.
Here are some inspirational links:
