Story

Hey all, I built Widget with young builders on my mind. I've made Widget with the Adafruit Crickit, which is the perfect tool to get into robotics, and it can be used to customize what your robot will be.

Adafruit Crickit

The Adafruit Crickit is the heart of this build. I want to note, I used a Hack Vape pen to make the smoke, so please note it's not part of the main build, but an add on. I will explain how I added it, but since it is a kid build, smoke can be dangerous, so please be responsible.

Assembly

First step is always printing out the parts. I always start off with the head. I used a Skyrim dragon base and added a ball joint. I try to print it at a 30-degree angle.

Dragon head

Next is the body and wings.

I want to give a special shout out to Thingiverse user "HSATURN". I used their Double wing flexi Dragon, to make the wings for widget. I added servo connectors to them so the wings can flap with servo control. {https://www.thingiverse.com/thing:3488794}

The body and the neck are next. The dragon neck has a servo placement, and it makes moving the head back and forth very easy.

Neck and main body

Adding it all together is pretty easy, the build is 7 parts in total. I did make a neck cover as well to hide the wires. It's hot glued to the body.

Neck cover

Smoke

The smoke detail I added later using this cosplay tutorial I found:

Widget has a hole in his neck that you can use a silicone tube and attach it to the end of the vape pen and feed it through the hole in his neck. I also used hot glue to seal it into the neck and to glue the vape pen to the base.

Please ignore the LED, that's for lighting up his mouth.

Finish

That's about it, I recommend using MakeCode to decide what you would like your dragon to do, and program it beforehand. Happy tinkering!
