      Could you provide any electrical specification?
      Extremely I want to know about EMS and multiplexer.

      I want to stimulate multi channel simultaneously.
      I understand that current firmware doesn’t support this feature.
      And it seems impossible to stimulate multi channel simultaneously because of multiplexer.

      I want to try turn on channel A a little time, and after that turn on channel B,
      and A, B, A, B…
      Probably I can feel it as weak A and B simultaneously.

      It is similar to drive multi-digit 7 segment display with limited ports.

      It works logically but I don’t know electrical limitation.
      If the specification doesn’t available, I want any information related to it.


        Thanks @kumadasu for your inquiry.

        I understand that you wish to deliver stimulus through multiple output channels.
        We are using 72V analog 8-to-1 multiplexers.

        Let us know how you plan on doing the modification and the type of information
        that you might need so we can better facilitate your project.

          I’m sorry for very long absence.

          I understand that you wish to deliver stimulus through multiple output channels.

          Exactly. I especially worry about switching time of on/off and channels.
          Are there minimum time for switching “on and off” and “channel A to B”.
          May switching too fast damage UH hardware?



            The current version of UnlimitedHand is not capable of outputting via multiple channels due to safety limit of the multiplexer.

            If you are a researcher and would like to deliver stimulus via 2 channels at the same time, we do have another device “PossessedHand” which is capable of doing so.

              I didn’t know PossessedHand. But I want hack without new purchase.

              I will hack unlimited hand more myself.

              Thank you.
