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

Discord GPT Chat Bot
DiscordGPTChatBot is a lightweight Python Discord bot that leverages OpenAI’s GPT‑3.5 with customizable system roles, giving server owners full control over the personality and responses of the AI. Configure behavior in a simple YAML file, run the included scripts, and watch as GPT‑powered conversations come to life in your Discord channels—with queueing, TTS options and easy deployment baked in.

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.
- Modular architecture with CPU (Numba) and GPU (CuPy) acceleration
- Parallelized video encoding maintaining delta and RLE compression
- Included Composite ESP32 player with experimental audio

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.
