Logic Circuits Simulator vs Bias Handbook

Logic Circuits Simulator is the digital design tool built for the way you actually study. Build circuits with IEEE-standard gates, sequential logic, Karnaugh maps, and reusable chips, all with schematic-quality wire routing that looks like the diagrams in your textbook. Rebuilt from the ground up for Version 3. COMBINATIONAL LOGIC Design with the full set of IEEE-standard gates: AND, OR, NOT, NAND, NOR, XOR, XNOR. Grow any gate from 2 to 8 inputs as your designs scale. Drop in constant rails, Ground and VCC, for clean schematic structure. Every gate auto-labels with its Boolean expression, complete with proper overlines for negation. SEQUENTIAL LOGIC Build counters, registers, and state machines that simulate live. Adjustable-speed clock with pause and single-pulse control. D, T, and JK flip-flops. SR latches. Every memory element exposes both Q and Q' outputs, the way your textbook draws them. SCHEMATIC-QUALITY WIRE ROUTING Wires route themselves with orthogonal paths, rounded corners, hop bridges over crossings, and junction dots at branches. Your circuits look like real schematics, not tangled diagrams. KARNAUGH MAPS & MINIMIZATION Flip any truth table into a Gray-coded Karnaugh map for 2-4 variables. See covering groups in color and the minimized sum-of-products expression, generated with Quine-McCluskey, the same algorithm your textbook uses. REUSABLE CHIPS Package any combinational circuit as a custom IC with named pins. Stamp instances like real chips, U1, U2, U3, into bigger designs. Build a full adder once, then drop four instances into a 4-bit ripple-carry adder. Your chip library syncs across devices via iCloud. TRUTH TABLES Generate truth tables for any circuit with up to 8 inputs. Intermediate gate columns show the signal flow, not just the answer. Export to CSV for your lab reports. 7-SEGMENT DISPLAY Drive a 7-segment display with 4 binary inputs to show hexadecimal digits, perfect for visualizing counters, decoders, and arithmetic circuits. BUILT-IN EXAMPLES Open working classics with one tap: half adder, full adder, 2-to-1 multiplexer, 2-to-4 decoder, NOR-gate SR latch, 2-bit ripple counter. Examples open as editable copies, learn, modify, and save your own version. ICLOUD SYNC Your saved circuits and custom chips sync across iPhone and iPad via iCloud. Start a design on iPad, finish it on iPhone. On-device-only mode available in Settings. SHARE YOUR WORK Export circuits as .lcs files to share via Mail, Messages, or Files. Embedded chips travel with the file, recipients see your design exactly as you built it. Export PNG snapshots and CSV truth tables for reports. WHY V3 IS DIFFERENT Logic Circuits Simulator V3 is a ground-up rewrite. New canvas, new tools, new everything. Circuits saved in 2.x migrate automatically the first time you open V3. Built by an engineering student, for engineering students. Always ad-free. No in-app purchases. No subscriptions. HAVE FEEDBACK? Email hkem.moh.ar@gmail.com. V3 was shaped by feedback from users like you, and the next version will be too.

Bias Handbook is a curated reference guide to the cognitive and behavioral biases that shape human thinking, judgment, and decision-making — now with visual diagrams for every bias and a built-in library of the behavioral-design frameworks professionals use to change behavior. Explore well-known biases such as confirmation bias, anchoring, survivorship bias, framing effects, the availability heuristic, and many more — each with a clear definition, real-world examples, a visual diagram, and links to related biases. New in this version: the Frameworks tab. Go beyond spotting biases to actually applying behavioral science, with 12 of the field's most trusted frameworks — COM-B, the Behaviour Change Wheel, the Theoretical Domains Framework, the BCT Taxonomy, EAST, MINDSPACE, Nudge, the Fogg Behaviour Model, Self-Determination Theory, Dual-Process (System 1/2), the Theory of Planned Behaviour, and the Transtheoretical Model. Each is explained in depth, illustrated with its own diagram, and cited to its original peer-reviewed or government source. Designed for students, researchers, product teams, behavioral scientists, marketers, investors, and anyone curious about how the mind works, Bias Handbook makes complex behavioral concepts easy to understand and accessible anywhere. Features: • A comprehensive, growing library of cognitive and behavioral biases • Visual diagrams — every bias has a clean, color-coded schematic that captures the idea at a glance • NEW — Frameworks tab: 12 in-depth behavioral-design frameworks (COM-B, EAST, Nudge, Fogg, and more), each with its own diagram • Diagnostic questions, end-to-end worked examples, implementation playbooks, templates, and practice exercises for every framework • Every framework cited to its original trusted source • Fast in-app search across names, aliases, and summaries • Filter by category — Decision-making, Memory, Belief & Probability, Social, and Self-perception, each with its own color • Bias of the Day — a fresh bias on the banner the first time you open the app each day • Bookmarks — save biases worth revisiting in a dedicated tab • Personal notes — capture how each bias shows up in your work or life, with a tab listing every bias you've noted • Daily reminders — set a time for a gentle nudge to learn one bias a day • Clean, intuitive browsing experience • Cross-references between related biases • An educational reference for psychology and decision science • Regular updates with new content Built by the Center for Behavioral Decisions, a research and consulting unit working at the intersection of behavioral economics, psychology, and decision science. Understand how biases influence decisions — and learn the frameworks to change behavior in everyday life and work.
