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:
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.
Ni-MH cannot supply enough power. You will need Li-ion 3.7V batteries in pairs. The size is 14500.
I have only tested Pi3B, Pi3A+, Pi0. Pi4 was released after Nybble.
The wood has one layer of coating. You can experiment with different paint(oil/water based) on the wooden frame after popping out useful pieces.
I am not a specialist in batteries but those batteries have the wrong voltage (1.2V instead of the preferred/required 3.7V) and form factor (AA instead of the slightly larger 14500 - this one is not required but a good indicator if you have the right batteries)!
I have NiteCore NL1485 850mAh 14500 3.7V 3.15Wh batteries. Try shopping in specialized battery shops but I bought mine in bol.com (living in Belgium).
(For the other questions, I haven't painted my Nibble (yet?) and although I bought a Raspberry Pi 4B and connected it, I have not experimented yet with it... took a break when I finally saw Nibble walking, yeah! Next vacation is make Nibble think...)
