According to the video [1], the MSP430 supports lychees, kiwi, papaya, mango, asian pears, lemons, and strawberries, and a quick Google search does not show anyone getting it to work with a potato. There's nothing stopping you from trying, of course, but these are all fruits and the firmware is not open source, so you may have difficulty getting it to recognize a potato.
