    HI Marten.
    I will probably re-print the finger-tips tomorrow and start again as I’m not happy with them.
    I am trying to get the measurements you asked for but the numbers are changing continually – going radically up and down. I have attached the red and black to each wire in the finger and have tried with a couple of fingers where the tip…[Read more]

    Hi, Marten.
    I understand now where to connect the SIP resistor. I note that there are type A and type B in those resistor networks. Is the one I need the type A? (isolated). I have been asking around but haven’t yet found anyone who knows or who knows which value I need. If you find out can you reply please?

    • Hi Humanoid,

      Can you measure for me the open value and the closed value from the sensor ?
      If I now these value’s, I can choice a SIP resistor value :)

      Thanks in advance…

      Regards,
      Marten

    I have a question about the finger-tip sensors. I notice that the nervo break-out boards have the same 3 input pins as the servo ones (pos, neg and S). The finger sensors only have 2 wires for each. The circuit diagram looks like the 2 wires go to the positive and S pins only. Is this correct? If so do we ignore the ground pin? Is there anything…[Read more]

    • You need to order two SIP resistor_network they look like this:

      The NervoBoard has the option to solder one at the sensor side.
      You need a 8-pin version (with seven resistors).
      I only don’t now which value you need to…[Read more]

    Hi there. I only just got your message as I’ve been hovering mainly around the myrobotlab shoutbox. I’ve just finished the head, torso, left arm, shoulder and lower stomach. Currently printing the right arm. Highly recommend the myrobotlab web-site. They are really helpful and friendly. Good luck with your 3D printer.

    Hi,
    I wonder if you can help me. I have printed out ClavifrontV2 and Claviback v2 and SternumV1. They don’t appear to fit together. I noticed there is no Sternum V2 for either front or back. The explanation mentions that one in the photos is the earlier version but it’s unclear which picture is being referred to. I assumed that ClavifrontV2…[Read more]

    Thanks very much. Hopefully my new 3D printer will have the appropriate software to open these files when it arrives.

    • Your 3D printer software will be able to read the STL files and convert them to a format that the 3D printer can use (g-code). But if you want to change them, the you need a 3D modeling software. I and many other people use Blender. It’s open source and free to use. You can find it here: https://www.blender.org/ After installing it you also need…[Read more]

    Hi, Does anyone know how to open the STL files in Windows 7? I keep getting a ‘Certificate Trust List’ error when I try to open the downloaded file? Does anyone know what this means?

    • This answer is in the Forum:
      You are using a Windows computer and the default file extension for STL is “Certification Trust List”. It’s a Windows thing. If you click directly on an STL file, you will get this message. You need to right click on an STL file and change the file association to whatever program you are using to view your STL…[Read more]
