This June I took a Friday afternoon tour to Sparkfun, organized by their new education department.

Greeting us at the entrance is a robotic dinosaur!

Like all hackers, we started with a grill…

Ninja dart attack!
Never knew this, but if you take lilipad parts out of the PCB board, what is left would work as ninja darts! Photo shot in their workshop space.

Testing driver board for stepper motors. Grrrrrr…..
