Really looking forward !! Will your Nybble supporters get an early info once you will promote it?

Would you mind sharing some STL once all parts are aligne and finished? I would love to print those in wood-PLA to give my robot an "exchangeable" head.

Great reengineering ... I love this forum. Good job Eric!

Hi! I do use this charger: https://www.amazon.de/gp/product/B0711YZ3YL/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 It works like charm.

Crowdfunding is always a risk for funders (as on every kind of financial business support, - ask shareholders). But in case of Rongzhong Li all supportes found a trustworthy and reliable person. So - "Thank you Rongzhong, for making this crowdfunding a success! Very good job." I personally made really worse experiences in past - but you need to stay confident.

Thanks for your reply. OK - understand that orders do have higher priority. Looking forward!

@Mr Robot & Rongzhong Li ; what exactly is function of that "extra capacitor in parallel with C3 (or the power line of any servo)." and how is it working? What type of capacitor did you use?

@robogeppo isn´t that is separate topic

see post: Partially alive ... it might help here, too.

Great support! It turned out, that a value of 580 works quite good as by now. NYBBLE IS WALKING! Many thanks Rongzhong Li !

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

Update: Finally it works! As assumed, rootcause had been the protected batteries. Type: Enerpower 14500 850mAh - 2,4A WORKS!

Got my ones from http://eu.nkon.nl in Netherland (I am myself from Germany). Type: Enerpower 14500 850mAh - 2,4A Not arrived yet. I will report, as soon as they are a ailable.

Works: SANYO 14500 800 mAh (based on thread Aaron Perkins , see post "Under voltage issues")

@ Christophe Cachin: maybe an important update for you, have a look at Frustration level: very high and REPORT: Batteries NOT working with NYBBLE

@ Felix Cat , Please check also your type of batteries. In case, you have an issue similar to above, please report.

Thanks for supporting with your cross check. That helped a lot, as I now at least have a new chance to get Nybble working one day. Well - that behaviour as shown in your video does now look much more like my pussy cat. Oh boy. At least - another a step forward. I should get my new batteries next week. I´ll report back, as soon as I can. Many thanks for your investigation. Looks like, that we get closer and closer to a better product. I would recommend to inform your supporters about this "issue" so they do not waste money as me on wrong batteries. Based on Rongzhong Li initiative, report your batteries in this post , please.

I´ve ordered a new set of "unprotected" batteries ... https://eu.nkon.nl/rechargeable/14500-16340-18350-18490-18500/enercig-14500-800mah-2-4a.html
