Electric Garden Workshop at Creative Coding Utrecht #1
> 22 March 2025
︎This was a 4-hour workshop (part one from two-parts workshop) organised to share knowledge on how to make microbial fuel cells, which are the basic components that make up the electricity-generating garden.
︎First hour was an introduction to the Electric Garden research by Sunjoo Lee. Afterwards, We made electrodes with stainless steel wool and carbon felt, and composed the mud cells in recycled containers. The mud was collected by Sunjoo Lee from puddles along the river Vecht in Utrecht.
︎The mud cells need time to brew, because microorganisms will start multiplying to large numbers on the electrodes and start making more and more electricity. This takes at least about one to two weeks.
︎There will be a follow-up workshop after two weeks, which will be about building energy-harvesting circuits that can use this mud cell’s electricity to power small motors or even microcontrollers, sensors and data transmitters.
