02Labs

02Labs is my portfolio for systems engineering, data work, security experiments, and technical writeups.

Introduction

Hi, I'm 02loveslollipop. 02Labs is my personal portfolio and lab, where I share projects, writeups, and experiments across systems engineering, data, security, and the other technical areas I like to explore deeply.

Focus (Or lack thereof)

I love lot's of things as you will see in my projects and blog. I think the best way to understand the world is by building, but something shouldn't be built just for the sake of building. I like to build things that are interesting, that solve problems, or that are just fun to me. But also I don't like to be superficial in what I learn whatever the topic is, for me that's a way to show respect to that thing and to myself.

OpenCROW

OpenCROW is an offensive-workflow workstation bootstrap for Codex agents that provisions a dedicated Conda environment, installs native and Python tooling for pwn, reversing, cryptography, and protocol analysis, and syncs vendored skills into ~/.codex/skills for tighter, domain-specific agent routing. It is designed to reduce setup friction during CTFs and security research by giving both the user and the agent a reproducible, modular, ready-to-use environment.

  • Modular toolbox design with separated crypto, pwn, reversing, network, and async workflow skills
  • Bootstrap installer for Conda-based CTF environments on Ubuntu and Debian systems
  • Integrated native tooling for exploitation, debugging, symbolic execution, disassembly, and analysis
  • Vendored Codex skills for persistent SSH, TCP, SageMath, and Minecraft-based challenge workflows

Bad Apple ESP32 Utilities

A clever suite of tools designed for retro-style ESP32 tech demos. Feed it a video and it slices the footage into frames, applies delta encoding and RLE compression, and outputs a bundled C array ready to be flashed directly onto an ESP32. While the original CodeMaker utilized a sequential Cython implementation, the Composite evolution features a modular, parallelized architecture running on Numba (CPU) and CuPy (CUDA GPU) resulting in exponentially faster encoding speeds, and adds native audio support.

LoRa L298N Tank Controller

LoRa‑L298N‑TankController is a hobbyist IoT platform for remotely piloting a tank‑style rover via LoRa radios. ESP‑based controllers drive an L298N H‑bridge while encrypted commands and telemetry flow through Redis streams and a modular microservice backend hosted in Docker‑containers on AWS. It’s ideal for experimenting with low‑bandwidth long‑range control, real‑time media relay and distributed telemetry.
