Perfboard Lab vs Circuit Simulator bitGateLab

Understand electronics by trying it out: Perfboard Lab turns your iPhone, iPad or Mac into an electronics lab. Build a circuit and switch on the power. Right away you see what happens: LEDs light up, buzzers beep, motors turn and hum. And if your maths was off: it smokes, it sparks and the part burns out – without any real damage. SEE WHAT HAPPENS, INSTANTLY • Every change is computed instantly with real physics • Overloaded parts smoke in four levels until they burn out • The analysis explains in plain words what is wrong: an LED the wrong way round, a missing series resistor, a short circuit, an open circuit MEASURE LIKE IN A REAL LAB • Multimeter: voltage, current and power at every part • Oscilloscope: voltage and current over time OVER 20 REAL PARTS • DC voltage source, AC voltage source, current source, solar module and breadboard power supply • Resistors, potentiometers, ceramic and electrolytic capacitors, inductors, switches • Diodes and Zener diodes, NPN and PNP transistors, N- and P-channel MOSFETs, relays, op-amps, voltage regulators and Timer NE555 • LEDs in six colours, an incandescent lamp, a buzzer with a real tone and a motor whose hum matches its turning • Sensors: photoresistor, NTC and PTC, with the brightness taken from the camera if you like JUST LIKE ON THE WORKBENCH • Draw wires with the pen – straight wires with bends and branches • Perfboard, with Perfboard Lab Pro also stripboard with cuttable strips and breadboard as used with Arduino • Copy parts with all their values; text labels annotate your circuit • Real 2.54 mm grid: what fits in the app fits on the real board • Bill of materials with every part and the length of hookup wire • With Perfboard Lab Pro you see your circuit in the 3D view: real parts on the board that you turn, tilt and measure PERFECT FOR SCHOOL AND CLASS • A guided tutorial starts with an LED that burns out and shows you how to find the right series resistor • A free task at your level every day: build, complete, adjust or rescue, with a time limit without Perfboard Lab Pro • AI-assisted tasks that suit your level and explanations step by step on the board (Perfboard Lab Pro) • Lots of ready-made examples: from an LED with a series resistor to logic circuits, transistors and op-amps • The formula collection calculates with the measured values of your parts and shows where each number comes from • Teachers pass their default settings on to the whole class as a file FOR EVERYONE • In many languages and usable with VoiceOver, Voice Control and Apple Pencil • No ads, no tracking FREE The perfboard with almost all parts and their examples, the daily task, text labels, the instruments and the simulation are free. A circuit can have up to 7 parts. PERFBOARD LAB PRO With “Perfboard Lab Pro” you save as many circuits as you like and keep working on iPhone, iPad and Mac. You export them as PDF with a bill of materials and share them with others. Plus circuits with more than 7 parts, op-amp, voltage regulator, Timer NE555, motor, Zener diode, current source, solar module and the sensors with their examples, the stripboard and the breadboard with their examples, AI-assisted tasks and explanations, and the 3D view. • Perfboard Lab Pro is available as a subscription (yearly, monthly, weekly). The App Store shows the prices before you buy. • A subscription renews automatically unless it is cancelled at least 24 hours before the end of the period. Payment is charged to your Apple Account. You can cancel at any time in your Apple Account settings under “Subscriptions”. • Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ • Privacy policy: https://pascalschroeer.github.io/PerfboardLab_PrivacyPolicy/ Legal notice: https://pascalschroeer.github.io/PerfboardLab_PrivacyPolicy/#legal-notice

Circuit Simulator bitGateLab is an electric circuits and analog electronics lab on your PC, phone or tablet: draw a circuit, measure it with multimeters and an oscilloscope, get its frequency response, turn it into block diagrams with the Laplace transform and build it on a 3D breadboard. Works offline, no account required. DRAW AND SIMULATE • DC, AC with phasors and time-domain transients, using modified nodal analysis (MNA), the same method SPICE uses. • Resistors, potentiometers, capacitors, inductors, transformers, thermistors and LDRs. • DC and AC voltage and current sources, a signal generator (sine, square, triangle and ramp) and dependent sources. • Diodes, Zener, LED, Schottky, NPN and PNP BJTs, N- and P-channel MOSFETs, JFETs and op amps with supply rails. • Undo and redo, copy and paste, rotate, replace components and node labels. MEASURE LIKE IN THE LAB • Voltmeter, ammeter, wattmeter and a multimeter-style probe on any node, pin or component. • Multichannel oscilloscope with a trace of every signal over time. • Bode plot (magnitude and phase) plus DC and frequency sweeps. LAPLACE AND CONTROL • Block diagrams: gain, H(s), integrator, differentiator, PID, delay, summing junction and saturation. • Turn your circuit into blocks and get its transfer function H(s). • Step response, poles and zeros, Bode plot and step-by-step diagram reduction. 3D BREADBOARD • Your circuit builds itself on a breadboard with resistors, capacitors, transistors, sources and wires. • Rotate, zoom and choose isometric, top, front or side view. PRACTICE EXERCISES • Generate fresh exercises on series-parallel simplification, mesh and nodal analysis, the Wheatstone bridge and AC RC, RL and RLC circuits. • Each exercise comes with its circuit, a graded question and a step-by-step solution. IMPORT AND EXPORT • Open SPICE netlists (.cir, .sp, .net) from ngspice or LTspice, including model libraries, and Falstad circuits. • Export to SPICE, Falstad and CircuiTikZ for your LaTeX documents, or as an image or PDF. FREE AND PREMIUM • Phone and tablet: every feature free, with circuits of any size and with ads; Premium removes the ads. • Premium: a monthly or yearly subscription, or a one-time lifetime purchase. FOR LEARNING AND TEACHING • Designed as a companion to an electric circuits course: whatever you work out by hand, you can check in the simulator. • Light and dark theme, European or American symbols. • 45 languages. PRIVACY No account and no cloud: your circuits are saved only on your device.
