// PRODUCTION-GRADE ENGINEERING
Solos HUD: Reverse Engineering & Redesign
Reverse engineering Solos smart glasses to build custom apps, followed by a complete hardware redesign and custom 3D-printed housing for enhanced portability and battery life.
V Plotter: V-Bot
A portable, dual-stepper V Plotter capable of drawing on large boards, featuring a web interface and modular crab-inspired gondola.
Underwater Scooter
2 builds — 2025-06-28 → 2025-07-02
Smart Ebike Charger
ESP32-based smart charger for a custom 6S ebike battery pack, designed to safely use a LiHV charger on standard LiPo cells by cutting off at a timed voltage threshold that accounts for IR drop. WiFi-enabled with live web dashboard and OLED display.
Head Tracking DJI O3 Air Unit
A 2-axis head tracking system for the DJI Goggles 3 and O3 air unit using an MPU module and ESP32 C3 Superminis.
Rapid Prototyping & R&D
// PROOF-OF-CONCEPT BUILDS
Water Sprayer FPV Drone
A mini FPV drone modified with a custom 3D-printed and salvaged syringe water pump system for a game of Senior Assassin.
Heated FPV Battery
An ESP32-C3 powered active heating system to maintain FPV battery temperatures in extreme -30°C winter conditions.
FPV Drone
4 builds — 2025-03-30 → 2025-10-09
FPV Gel Blaster Drone
6-inch analog FPV drone rigged to carry and fire a gel blaster, combining FPV freestyle hardware with a combat payload.
April Fools ESP32 Prank Devices
Fleet of ESP32 prank devices deployed on April Fools using ESPNow — the first time deep sleep was used to extend battery life. Came with 3D printed fake AirPods as decoy props.
Smart Glasses for the Blind
Glasses fitted with an ultrasonic sensor and speaker that beep to warn visually impaired people of nearby obstacles.
Static Electricity Generator
High-voltage static electricity generator using a voltage multiplier and AC HV circuit, repurposed as a wearable negative ion generator with a ground plane touching the floor.
Custom RC Flying Wing
Fully custom RC flying wing with a scratch-built controller board translating ELRS CRSF signals to SBUS for the servos via an ESP32. Never flew — lives in the project drawer waiting for its moment.
Air Quality Sensor
ESP32-based sensor logging PM2.5, VOCs, temperature, and humidity, with an OLED readout and an Adafruit MQTT dashboard. Enclosure uses a cheap IKEA part as the structural base.
BLE Macropad
2 builds — 2025-01-06 → 2025-01-10
Night Vision Goggles
DIY night vision goggles with a high-power IR illuminator and a dual-battery system for extended runtime.
Smart Ski Goggles V1
A smart ski goggle prototype built in one day that uses internal reflections to display the time.
Custom Ender 3 — Klipper Build
A fully rebuilt Ender 3 running Klipper with a direct drive extruder and PEI sheet. Started on a Raspberry Pi Zero 2W, migrated to a Pi 4 after persistent crashes. Still the main printer.
Weekend Hacks
// THE SCRAPBOOK
Remote Firework Detonator
A remote and timed detonator for a firework rocket built in 30 minutes using an ESP32 C3, a relay, and a custom match igniter.
Stark Varg Charger Case
Compact 3D printed enclosure for the Stark Varg electric motorbike charger, designed from scratch in Onshape by measuring the original unit. Abandoned — the Ender 5 available at the time couldn't print it reliably.
Ebike 48V to USB-C PD Adapter
Step-down adapter that taps the ebike's 48V battery and outputs USB-C Power Delivery, turning the bike into a mobile charger.
Automatic Curtain Opener
Morning curtain automation built by hacking a smart plug. Worked flawlessly every day for two months before the mount gave up and it fell off.
3D Printed RC F1 Car
Fully 3D printed RC F1 car running brushed motors and ESC gifted from a friend, with FlySky radio control. First project to use TPU and bearings in a 3D print.
Ski Helmet Speaker
Custom speakers built to fit flush inside the earcups of a ski helmet, completely hidden from the outside.
DIY Electric Turbojet
An attempt to build a functional turbojet using an electric turbocharger — a BLDC motor spinning a custom-designed turbine to force air into a combustion chamber. It failed, loudly.
Desk Build
Custom desk built from scratch with $60 and a drill. Still standing.
Electric Skateboard
Fan-powered electric skateboard built on a shoestring budget using a cheap Amazon ESC, motor, and a 3S LiPo. A propeller and printed fan shroud replace a conventional belt or hub drive.
