Hey! I'm going to be getting a Nybble in the new year, possibly two, so please note I haven't yet got the actual bot in hand :-) Sorry in apologies for the litany of questions, I've been looking/researching and can't find the answers, so I'd just like to make sure. I'm looking at batteries for powering it, and I'm based in the UK. Amazon search gives me this option, I just wanted to check it will be suitable: ( https://www.amazon.co.uk/EBL-Capacity-2800mAh-Rechargeable-Batteries/dp/B01JGF425I/ref=sr_1_fkmr0_1?keywords=EBL+14500+3.7V+800mAh&qid=1575860598&sr=8-1-fkmr0 ) Furthermore, with regards to customising the frame: what sort of paint is suitable. I'm assuming acrylics, or acrylic airbrushing, but I just want to double check. Obviously, this will just be the wooden frame not any of the mechanisms/bits behind it. I was just thinking of something silly like adding tabby stripes. Finally, perhaps a silly question: I'm going to be mounting a Raspbery Pi to it, hopefully. Is 3 (Model A), or 4, more suited? And, do you just add it to the frame of the body/board -obviously with relevant connections-, which is as I understand it? I'm pretty ok at model-building, and fairly average at programming so I'm hoping the "learn as you go" approach will be suited, plus the open source nature and all the really good community resources. Cheers :-)

Just wanted to share my 3D printable version of the original Nybble as seen in Volume 70 of Make Magazine. This is such a great little design and my daughter is loving her new pet kitten! https://www.thingiverse.com/thing:4015171
