The last 5 months have been incredibly busy for me. I have been teaching electronics and design at a high school in San Francisco.

It was stressful at times -teaching and learning programming simultaneously can get you in a muddle, but it was also wonderfully rewarding to be learning with students, and to work in a collaborative way.
Here are a few of their project pages:
