555-timer

Yet another Atari Punk Console 🙉 hardware implementation

Photorealistic 3D breadboard simulator in your browser — real analog+digital circuit sim, path-traced renders, Liquid Glass UI, AI circuit generation. Zero microcontrollers.

A basic full-bridge inverter built to demonstrate the conversion of DC (battery) power into AC (alternating) power using electronic switches and the principles of PWM. (2019-20)

555 Timer PWM Driver with Schematic, PCB, and Case

An Atari Punk console with dual NE555P chips.

Density-based traffic light built entirely from discrete logic ICs — counters, a comparator, flip-flops and 555 timers decide which road gets green. No microcontroller, no firmware. Proteus simulation.

An old school digital clock made using transistor-transistor logic chips: counters, logic gates, flip-flops and other integrated circuits.

Designed and simulated a Pulse Amplitude Modulation (PAM) system using a 555 timer as the sampling pulse generator and an analog message signal in Proteus/LTspice and KiCAD

Aspiring Full Stack Embedded Engineer with hands-on experience in automotive electronics. Passionate about turning complex schematics into high-quality, manufactured hardware. My first major project, the J-Letter Sequencer, was proudly sponsored by PCBway.

A 555 timer based servo controller designed in KiCad, including the schematic, PCB layout, 3D model, and fabrication files

Hardware reaction time game using 555 timer, 4017 counter and 4011 NAND gate

Pure hardware implementation of a 3‑digit safe lock using off‑the‑shelf logic ICs (no firmware/microcontroller).

Hands-on electronics portfolio with Multisim and Altium Designer projects, from LED timers and guitar circuits to power, automotive and ATmega644PA PCB designs.

Two-stage inverting amplifier (buffer + summing/low-pass filter) and a three-NE555 timing chain generating a delayed pulse per clock edge — designed, simulated in TINA-TI, and verified on the bench.

Design of A Colour Sequence Detector for a 5-core Harness Cable

Schematic and PCB design for an adjustable LED flasher circuit based on the NE555 timer IC configured as an astable multivibrator.

This project was done during course ELEC 291 at UBC (University of British Columbia) in February 2022.

Analog hardware-only driver drowsiness alert system built using 555 Timer IC logic — no microcontroller involved.
