I revised the PCB so that it's now IEC60601-1 compliant for safe use on humans as well as with 32 electrodes for better spatial resolution. Also there is updated software with a choice of Gauss-Newton approximation, Back Projection and GREIT algorithms available at https://github.com/openeit

See the new higher resolution image reconstruction! 

Super small PCB with Bluetooth for wireless transmission too. Still working on refining the details but so far so good! 

Soon, after one last PCB revision(yes the final one now *fingers crossed* ), I'll start generating more test images on humans and animals and of course - fruit.
