Learn to build the machines you're curious about
Five tracks, from first circuit to physical AI. Every lesson comes as a written tutorial, most add video, exercises you can run in the browser, and a worksheet you can print.
01
Robotics & electronics
14 lessons · beginner-friendly
Circuits, sensors, motors and microcontrollers — from blinking an LED to a robot that reacts to its world. Starts with zero assumed knowledge.
02
Engineering & maker projects
11 lessons · hands-on
Design thinking with real materials: CAD basics, 3D printing, mechanisms and enclosures. Every lesson ends with something you can hold.
03
Large language models
9 lessons · no math wall
What LLMs actually do, how prompting works, and how to build small useful tools on top of them — explained without hand-waving or hype.
04
Agentic AI
7 lessons · intermediate
Give a model tools, memory and a goal. Plan-act-reflect loops, guardrails, and where agents genuinely help versus where they flail.
05
Physical AI
6 lessons · capstone track
Where the other four tracks meet: perception, control and learning on real hardware. Build machines that sense, decide and move.
Written tutorials
Step-by-step, skimmable, with every schematic and snippet inline.
Video lessons
Watch the build happen — wiring, debugging, the mistakes included.
Interactive exercises
Simulators and checkers that run right in the browser — no setup.
Worksheets
Printable practice for classrooms and kitchen tables alike.
Pair a lesson with its kit
Most builds have a matching parts kit and worksheet pack in the store, so nothing stalls on a missing resistor.
