33 Next Steps
hut edited this page 2 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
  • Try I2C for communication between the individual PCBs. Add a 4-channel ADC with I2C output to each electrode module. Connect each board via daisy chain
  • 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
    • A way to avoid through-hole components for attaching the Arduino is to add contact pads on the power module to which the arduino can be directly soldered on to.
    • Surface-mounted AAA battery clips are available
  • Redesign it so that a PCB manufacturer can assemble it completely, except for screws, wires, and elastic bands.
  • Rectification



  • Publish datasets of recordings -> Sample Signals blog post
  • 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 -> BOM blog post
  • Add blog post on P8/P9's electrode module configurations


  • Add read-only mirrors on GitHub
    • Automate synchronization


  • Design and print stickers
  • Find sponsors
