🎓 B.Tech Engineering Labs

124 virtual experiments that compute for real in your browser: a SPICE-style circuit solver, FEA, lattice-Boltzmann CFD, heat transfer, cycle analysis, robot kinematics, a G-code CNC, DSP and BER, antennas, PID, embedded C compiled by Clang, and Verilog synthesised by Yosys. Every experiment has its own live 3D bench.

🔌 Electronics28 experiments · Devices, analog circuits, op-amps and power electronics, simulated by a SPICE-style circuit solver on a breadboard with a live oscilloscope. 📡 ECE22 experiments · Signals and DSP, analog and digital communication, antennas, links and control systems with real FFT, filter, BER and PID computations. ⚙️ Mechanical35 experiments · Strength of materials, FEA, CFD, heat transfer, thermodynamics, vibration, robotics, CNC and machine elements, each with its own live 3D rig. 🔧 Embedded Systems19 experiments · Microcontroller programming in real C (compiled in your browser), sensors, PWM, servos, displays, serial buses (UART, SPI, I2C, CAN) and RTOS scheduling. 🧩 Chip Design (VLSI)20 experiments · Verilog RTL synthesised by real Yosys in your browser, gate-level simulation with checks, waveforms (VCD), area and timing estimates, and a 3D die view.

How these labs are real

  • Electronics / ECE: modified nodal analysis with Newton–Raphson (diodes, Zener, BJT, op-amp), transient and AC analysis; radix-2 FFT, windowed-sinc FIR and bilinear Butterworth IIR; Monte Carlo BER checked against erfc theory.
  • Mechanical: direct-stiffness FEA (matches beam formulas to 5 digits), lattice-Boltzmann D2Q9 CFD (Strouhal ≈ 0.167 at Re 100), finite-difference heat conduction, air-standard cycles, RK4 vibration, analytic inverse kinematics, a G-code interpreter.
  • Embedded: your C is compiled by Clang (WebAssembly) and runs against virtual time; UART/SPI/I2C/CAN frames with real CRC-15 and bit stuffing; RTOS scheduling with priority inheritance.
  • VLSI: Yosys synthesises your Verilog to gates in the browser; the gate netlist is simulated cycle by cycle with checks and exported as VCD.

These are teaching simulations. They are not certified SPICE, FEA, CFD or sign-off EDA tools, and simulated values are not physical measurements.
