Creative Name of the Skill I Learned
What I wanted to learn, and why it interested me: [Your text goes here. Should be a short description of what you wanted to learn and why you chose it. A couple of sentences.]
Final outcome: [Your text goes here. Should be a short description of where you got to in your final build. A couple of sentences.]
Images of final creative/exploratory output
[Final image or video. Your image caption goes here. Remember to add alt text if needed.]

Process and reflection:
[Your text goes here; at least 150 words. Address what your process was, e.g. what did you make/do first; how did it go; what did you make/do next; etc.
Include a reflection at a minimum addressing what you learned, any surprises along the way, and how you feel about where you ended up.]
Technical details
[Electrical schematic. Add a brief caption for clarity; this could be as simple as "Electrical schematic" but you can also use the space to describe anything that would be useful for your reader, e.g. "The 12V power came from a LiPo battery, not drawn."]
