Big update! Ohmie's been busy at the workbench: - Ohmie World (Beta) is open. Find the door in Projects: walk Copper Town, light your first LED with Pip, take the Copper Trail and duel its trainers on a real breadboard. Sign in and head west to the Battle Grove to challenge other inventors live: same questions on both phones, first correct answer scores, first to five. - Ohmie World keeps going after the first day. A daily loop that hands you the next thing to build, the Digital Village to explore, arena levels that grow with your live battles, and a battle review so you can see what you got right — and wrong — before the rematch. - The Logic Lab is now a native 3D world. Fly it, land at ten level walls and build real circuits from a single lamp up to a latch and a clock, banking XP as you climb. No web view, all native. - Ohmie now speaks Spanish, Czech, Brazilian Portuguese and German. Pick one in Profile → Language (German is still being finished). Lesson narration stays English for now. - Robotics grows by 23 lessons (Grippers & Grasping, Motion Planning, Robot Balance, Robot Decisions) with Blender and MuJoCo scenes, and Degrees of Freedom gets its own section.

Big update! Ohmie's been busy at the workbench: - Logic gets its own wing. A whole Combinational Circuits unit lands: OR, AND, NOT, NAND, NOR, XOR and XNOR, each with a hands-on studio where you flip the inputs and watch the truth table fill itself in. The MUX and the SR latch move in next door. - Logic Lab, torn down and rebuilt. A cleaner ink-and-cream bench, real wire routing, and pinch to zoom out when the build gets big. Four new projects to wire: the SR latch, the flip-flop, the D latch, and a full ALU laid out the way Ben Eater does it. - Charge & Electrons starts over, properly. The opening section is rewritten lesson by lesson: see the idea revealed, build it on the bench, then prove you have it. No more reading about electrons. - Every lesson reads itself now. Recorded narration covers the whole catalogue, not just the early sections, and each page reads once on its own. Mute is per lesson, so you decide where the voice helps. - Ohmie wakes up. A new loading screen where he looks around and blinks before handing you the app, a streak flame that stays cold until today's lesson is done and then catches, and a lesson-complete screen that charges up your daily goal like a battery.

Big update! Ohmie's been busy at the workbench: - Arduino has entered the workshop. A new track in Programming starts at the very beginning: What Is Arduino? — what that little blue board actually is — then Hello, World!, where you write your first real program and the board does what you told it. No setup, no fuss, just code that runs. - 1947 — The First Transistor. A new story lesson rebuilds the Bell Labs breakthrough bench by bench: seven experiments from a bar of germanium to the moment the signal came out bigger than it went in. The part that started everything, built by you. - Sensor lessons come alive. Three lessons that used to be read-only are now labs — drag, tilt and probe the sensor yourself instead of taking our word for how it behaves. - Signing back in is instant now. Ohmie recognizes returning accounts — no walking through onboarding twice, and your leaderboard name is your account wherever you play.

Big update! Ohmie's been busy at the workbench: - Your progress now follows you. Sign in once and your streak, XP, coins and finished lessons ride along to every device you own. Start a lesson on your phone at lunch, pick it up on your iPad that night. - Digital Circuits is its own subject now. Thirty lessons of bits, gates and the machines that compute, opening with How Chips Speak: how electricity carries information at all, before a single 1 or 0 turns up. Predict what the circuit will do, then watch it actually do it. - Build an AND gate out of real transistors. Wire two of them in series and see for yourself why both inputs have to be on. One light source, no diagram standing in for the thing, just the thing. - Ohmie shows up after your first lesson. He turns up animated, asks whether you're coming back tomorrow, and your streak starts right there. - Flashcards for Digital Logic, plus a review sheet for The Two-State World, so binary sticks before the gates arrive. - You decide what gets built next.

Big update! Ohmie's been busy at the workbench: - iPad learned to rotate. Every orientation now works — flip to landscape mid-lesson and paths, benches and labs re-flow to fit instead of locking you upright. - Components got rebuilt around seven hands-on benches. Read resistor color bands and stack your own band by band, sweep a potentiometer, flip real switches, seat a diode the right way round — then wire up an actual night-light from the parts drawer. - Capacitors is a full section now: nine benches of charging, holding, draining, fading and bursting, capped with a decoder bench that makes timing finally click. - Circuits II gets analysis you can feel — six new benches that put loads and loops under your fingers instead of behind formulas. - New WHY? button, starting in Circuits I. Every answer keeps its explanation one tap away — peek when you're curious, skip when you're sure. - The Discord door now stays open for good — grab the permanent invite from the News tab and come hang out.

Big update! Ohmie's been busy at the workbench: - Ohmie now runs natively on iPad. Every lesson, lab and build gets the bigger screen, with the layout tuned so circuit paths and benches stay readable instead of stretching to the edges. - Onboarding is career-first: Ohmie asks what you're actually building toward, then the new Recommended for You shelf keeps your next step one tap away instead of buried a level down. - Circuit Lab opens with new guided starter projects, so there's always something on the bench to pull apart. Zoom is smoother, board length now fits the circuit you're building, and the bench got polish throughout. - OhmieCAD free play gets a proper COMPONENTS picker — the parts catalog laid out as a grid you can actually browse. Boards can be reshaped, and the error checker got a lot stricter, so your design tells you what's wrong before you build it instead of after. - Build an 8-Bit Computer got a full visual overhaul, and the leaderboard is cleaner with a redesigned weekly card. - Your First Circuit is back, seated right after Components.

Big update! Ohmie's been busy at the workbench: - Build Your First PCB is now coached end to end. Ohmie walks you through all six studio beats, one step at a time — pointing at the exact control he wants with an amber pulse, stepping in when you stall, and celebrating when the board comes together. - The PCB studio got easier to handle: drag chips to move them, a hint when you tap the tray and nothing happens, a bigger close target on the mission header, and the board now pans straight to any error the checker finds instead of leaving you hunting for it. - The Voltage Divider lab earns its second scope probe. PROBE 2 unlocks in the scope mission with its own guided step, and the oscilloscope draws both channels together — a flat input over the climbing output, so you can finally see the divider doing its job rather than take our word for it. - Every new divider lab now opens on a genuinely empty bench, and FINISH re-checks your wiring against the real board before it banks the mission.

Big update! Ohmie’s been busy at the workbench:     •    NEW Programming — two complete tracks. Arduino Coding is 114 lessons across 19 sections: your first Blink sketch, C++ types, loops, functions, digital and analog I/O, PWM, timing, the serial monitor, state machines, structs and classes, libraries, motors and drivers, I²C/SPI/UART, and a final autonomous robot. Python Basics runs 67 lessons from print and variables through lists, dictionaries, functions, modules, classes and debugging.     •    NEW Semiconductors — the transistor, taken apart properly. Eight sections and 60 lessons: what’s actually inside one, meeting the BJT, MOSFETs as switches, building logic out of transistors, using them as amplifiers, driving real loads, and how to choose and debug the thing when it misbehaves.     •    NEW Circuit Lab — a free-build breadboard sandbox with capacitors, switches and an oscilloscope, running on a transient engine that tells the truth about what your circuit does. The Projects tab is now three doors: Circuit Lab, PCB Lab, Robotics Lab.     •    NEW Your First Circuit — twelve lessons that take you from nothing to a working loop.     •    NEW SLAM — nine lessons on how a robot builds a map of a place it has never seen while working out where in that map it is.     •    NEW Flashcards — 8 decks, 117 cards, every symbol hand-drawn: Circuits I, Circuits II, Components, Capacitors, Diodes, Transistors, Op-Amps, and PCB Basics. Quick-fire recall for what you just learned. Decks open as you finish the course behind them.     •    NEW Review sheets — a one-page poster behind every deck. The whole topic laid out in symbols, worth reading before you drill and long after.     •    NEW Robot Kinematics — two full courses. Forward Kinematics turns joint angles into where the hand lands; Inverse Kinematics works backwards from a target to the angles that reach it, including the two answers every elbow has and how to pick the better one. Each ends in a lab where you drive the arm yourself.     •    NEW How Robots Sense Motion — nine lessons on the IMU: accelerometers, gyros, and how a robot works out which way is up.     •    NEW Inductors — eight lessons on the part that fights change: why current cannot jump, what the turn-off kick is, and where the energy actually goes.     •    NEW RC Circuits and Decoupling Capacitors — the charge-and-discharge pair behind timing, plus why every chip on a board wants its own little reservoir.     •    NEW Meet the Arduino Family and Arduino Uno vs. ESP32 — which board to reach for, and what changes when you move up to Wi-Fi.     •    NEW project: The RC Delay Switch — eight modules on the resistor-and-capacitor pair that makes a circuit wait. Watch the capacitor fill, size the delay yourself, then build it for real on the bench and probe it like you would with a scope.     •    Interrupts rebuilt — twelve lessons, from “stop polling” to debouncing, volatile, and waking a sleeping board.     •    Serial Protocols rebuilt as one course — UART, SPI, and I²C, each opened up message by message, ending by wiring a robot with all three.     •    PCB Basics rebuilt, two lessons longer. “Build it for real” hands you the loose circuit from lesson one and has you construct it on a breadboard — real parts, real rows — before the course turns it into copper. “How parts hold on” covers through-hole against surface mount, and why anything that gets yanked goes through a hole.     •    NEW Top 5 Mistakes — the five classic beginner blunders in PCB design, and how to dodge each one.
