SparkFun Electronics will be closed on July 3rd, 2015 in observance of Independence Day. Any orders placed after 2:00pm MT on July 2nd will be shipped out after the weekend. Thanks!

  • The Arduino code is meant to be run along side the Processing code. It outputs all six pins so you can connect up to 6 sensors and view their output graphically via Processing.

  • The biomedical pads are probably too big for measuring eye muscles but the sensor should be able to pick them up if appropriate pads are used.

  • Are you driving the servomotor directly with the sensor? Usually this is done with a servo driver or microcontroller. If using a servo driver or microcontroller, you’d simply need to map the input values to higher values before sending it to the servo. You could also alternatively increase the sensor gain via the potentiometer marked as Gain in the middle of the board.

  • This is actually the same sensor board as before. The difference is that the sensor board was packaged as a kit but is now sold separately.

  • “Cost of delivering” is already paid for by the customer requesting said “huge volumes of traffic”. ISPs just want to double dip instead of innovating.

  • Have you seen this DIY prosthetic arm? http://www.thingiverse.com/thing:408641

    It was featured on the Today show and only takes ~$250 in parts to build.

  • I’d rather find out before I purchase it…

  • How do the colors align with the 3.5mm jack? e.g. Tip - black, ring - red, sleeve - blue

    • Make sure the cable plug is pushed all the way in the port (yup it happens a lot)
    • Verify the voltages at the power pins are correct (eg +9V to +Vs, -9V to -Vs for 9V battery setup)
    • Make sure you aren’t reusing the electrodes. The ones that come with the kit are one time use only.
    • Check the value of the gain potentiometer with a multimeter on resistance setting. Should be ~20 to 50 kOhm.
    • Electrode placement is really important. If you aren’t sure if you’re placing the electrodes properly, contact Advancer Technologies.
  • Will a 14-TSSOP fit this board?

No public wish lists :(
