24 Next Steps
hut edited this page 3 months ago

These are potential directions that the project could go in the future:


  • Turning it into a musical instrument
  • Connecting it to an extra thumb (see paper) (By going to https://plasticity-lab.com/publications and clicking on the link with the same title as the paper, one can access the full paper for free)


  • Switching to another instrumentational amplifier that works at 3.7V and switching to a lithium battery that supplies 3.7V, eliminating the need for a power converter
  • Switching to operational amplifiers instead of instrumentational amplifiers (to save cost, and perhaps space on the PCB)
  • Adding multiplexers to allow for more than 8 signals
  • Fixing interference issues on signal 2
  • Use linear regulator chip instead of opamp for generating reference voltage
  • Try decent electrodes
  • Use surface-mounted (SMD) pin headers (alternative) and pin sockets instead of through-hole ones to eliminate points of contact on the underside of the PCB
  • Redesign it so that a PCB manufacturer can assemble it completely, except for screws, wires, and elastic bands.
  • Rectification



  • Publish datasets of recordings
  • Publish trained NN model
  • Record a video of setting up a Linux environment to run PsyLink
  • Create data sheets for recent prototypes
  • Create tutorial for running PsyLink UI
  • Add bill of materials to prototypes


  • Design and print stickers
  • Find sponsors
