Dear Early Bird Backers,

In case you receive Nybble early, please find the following animations as basic assembling instructions. Some of them were created earlier and are slightly different from the version you receive. I'll update them in the coming week and add more notes to help you figure out the puzzle.

When assembling, there shouldn't be any part that requires excessive force. So be careful not to break those tiny pieces, but take careful observations on the videos. If you have any questions, please post them here with pictures or videos.

Thanks for your support and now let's start a wonderful journey together!

Happy New Year!

Based on your feedback, I'm making a shared google doc to better chapterize the following tutorial. You can comment on each section to help improve its contents. If you caught me editing the document, we could even chat in real-time! After the contents are pretty fixed, I'll find a better way to present it on a dedicated webpage.

In the tutorial playlist, I have more hand-on instructions besides the animations.

If you have a problem during use, please post under the Clinic category and describe your question with a short subject. Thank you!

Part list:

There are five different screws used in the kit. I think coloring them differently is more helpful than words:

A is for attaching servo arms. D (sharp tip) is for attaching servos to the frame. A and D come in each servo's own little bags.

B is for attaching servo arms/circuit boards to the frame. In later versions, it will be replaced by C.

C (flat tip) is for binding the thighs.

E (always the longest) is for the battery holder.

There are three types of springs. The 9x thick springs are for the thighs; the single thick short spring is for the neck. It will be replaced by the previous thick springs in later versions; the two thin short spring is for the battery holder.

The metal hinge of the battery holder should be bent towards the battery pack to avoid blocking the knee servo's path.

There's an update on the shoulder pieces:

You may notice that the 4th piece (pink) is almost the same except the curve on one side is cut flat. It’s actually an improvement. It's adjusted to accept a Raspberry Pi and give access to its two USB ports. If you are assembling Nybble as is, put the pink one on the bottom side of the tail shoulder. If you want to add Pi later on, put the flat one on the top side of the tail shoulder. In that configuration, you won't be able to install the spine due to the height constraints.

Again, make sure you read the tutorial (google doc) before assembling!
