Do you have a link for the part and any details how you connected it to the Pi?

Looks good! What's that installed in the other eye socket?

These worked for me: Enerpower 14500 850mAh - 2,4A Netherlands https://eu.nkon.nl/rechargeable/14500-16340-18350-18490-18500/enercig-14500-800mah-2-4a.html

@Mr Robot What value capacitor worked for you? From the photo I guess you just plugged it into one of the three unused servo connections on Nyboard

Thanks @Rongzhong Li I think I'll try adding an additional capacitor first as that seems to have less of a downside than the reconfiguration.

I guess this is the same issue as https://www.petoi.com/forum/clinic/partially-alive

I bought some Enerpower 14500 850mAh - 2,4A batteries and managed to complete calibration. I can now reliably switch between poses and the servos return to the correct position each time. However, I have noticed that the Nyboard resets sometimes when all the servos move either when running the WriteInstinct program or the Nybble program (Nybble beeps and I see the same text in the serial monitor as when I reset the program). I'm guessing that the power drain causes a brownout on the controller. @Rongzhong Li is this expected? Is there a workaround?

@Ton van Overbeek That's interesting. I had "all" selected and could find Qlist and the Adafruit driver but not IRemote

Wow, that's really unintuitive. I hit the same issue as Boris today with Nitecore 14500 Li-ion Battery 850mAh NL1485. I've just ordered some Enerpower 14500 850mAh - 2,4A batteries.

Doesn't work: Nitecore 14500 Li-ion Battery 850mAh NL1485

@Rongzhong Li 1.8.9 on both Linux and Mac

The google docs specifies installing Remote via the arduino library search: "Go to the library manager of Arduino IDE (instruction: https://www.arduino.cc/en/Guide/Libraries), search and install Adafruit PWM Servo Driver, IRremote and QList." This didn't work for me (no search results for IRemote). I had to go to https://z3t0.github.io/Arduino-IRremote/ and install it as a .zip library
