CraftingTable — Learn Electronics By Building Real Circuits

CraftingTable (formerly Inventr.io) makes story-driven electronics kits. Each kit comes with a filmed video course: you build real circuits on a breadboard and program a microcontroller, starting from zero experience. 24,000+ customers in 34 countries, selling kits since 2018.

Our best-known kit is 30 Days Lost in Space: 31 filmed lessons (Day 0 to Day 30), about 10 hours of video, taught by Dr. Greg Lyzenga, a Harvey Mudd College physics professor and NASA JPL scientist. Ages 12 and up (as printed on the box). The kits use the HERO Board, HERO XL, T-Display ESP32 and Raspberry Pi Pico WH, programmed in C++ and MicroPython. The video lessons for every kit are free to watch on this site.

Free Browser Circuit Simulator

Build and run real circuits in the browser with no hardware at all. The circuit simulator emulates the actual microcontroller chip, so the code that runs in the simulator runs on a physical board. Wire parts on a virtual breadboard, write the code in the built-in editor, compile it, and watch LEDs, buzzers and displays respond. Finished code can be flashed to a HERO Board over USB straight from Chrome or Edge. Open the simulator.

Daily Quest

A new circuit challenge every day at /daily-quest: finish the wiring or fix the code. Free, no kit required, solvable entirely in the simulator.
