EV Go-Kart Fleet Maintenance System
RPM Raceway · Work Project · Feb 2025–Present
● Live
Summary
Hands-on EV systems work maintaining a fleet of 60+ electric go-karts at RPM Raceway. Day-to-day responsibilities include battery pack diagnostics, electrical fault isolation, drivetrain servicing, and developing a consistent pre/post-session inspection process.

Full Details
Fleet Scale
60+ electric karts, 8–12 operational sessions daily. Each kart runs multiple back-to-back sessions — any downtime directly impacts revenue, so turnaround speed and accuracy matter.
Battery Systems
Cell voltage monitoring, charge cycle tracking, capacity degradation assessment, and connector/terminal maintenance on multi-cell lithium packs. Identify and swap degraded packs before they fail mid-session.
Fault Diagnosis
Electrical fault isolation across motor controllers, wiring harnesses, and battery management systems. Use multimeters, load testers, and visual inspection to diagnose under time pressure.
Real-time IoT energy monitor built on an ESP32 DEVKITV1. The PZEM-004T v3.0 measures AC voltage, current, watts, and cumulative kWh over UART. A 20×4 I2C LCD refreshes every 500 ms, a DS1307 RTC timestamps all readings to a microSD card, and the ESP32 pushes data to ThingSpeak over WiFi every 15 seconds. Test results with a 60 W load: 118.3 V, 0.48 A, 56.7 W — all within 5%. Total build cost: $86.41.
Most home energy monitors cost $80–$299+ (like the Sense) and still require subscriptions. Goal: a sub-$90 open-source build delivering real AC readings — voltage, current, watts, and kWh — with cloud logging and no recurring fees.
What I Built
ESP32 monitor using PZEM-004T v3.0 over UART, CT clamp for non-invasive current sensing, 20×4 I2C LCD at 500 ms refresh, DS1307 RTC for timestamps, microSD for local CSV logging, and ThingSpeak cloud push every 15 seconds over WiFi.
Issues I Solved
Fried an ESP32 by connecting the 5V ACS712 output directly to a 3.3V ADC pin — rebuilt with an inline fuse. CT clamp was on the neutral wire (reading 0A) — moved to live wire. LCD showed nothing — found a missing I2C jumper wire.
Results
60W test load: 118.3V · 0.48A · 56.7W — all within 5% of expected. LCD: 500ms refresh. ThingSpeak: 15s update. Total cost: $86.41. Build time: 88 hrs vs 57 planned — extra from troubleshooting the fried board.
Five register-level 8051 Assembly programs written for CTEC 350 — Microcontroller Based Systems. Work covers timer modes, interrupt-driven routines, keypad scanning, 7-segment display multiplexing, and look-up table implementations. Final project: a 4-digit safe keypad system with combo lock logic, multiplexed display, and ISR-driven scanning.
A 4-digit combination lock using a 4×4 matrix keypad and 4-digit multiplexed 7-segment display. Timer 0 Mode 1 ISR drives the display multiplex at ~1 ms per digit. The keypad scanner reads rows/columns on P1 and maps presses through a look-up table. When digits 3-5-7-9 are entered in sequence, the display flashes OPEn. The * key clears entry at any time.
16-bit timer (Mode 1) generates a 200-cycle delay between counts. Counter starts at 15 and counts down to 0 on Port 1 connected to a 7-segment display. Values translated through a look-up table at address 300H for 7-seg encoding.
Same countdown logic but using Timer 1 in Mode 2 (8-bit auto-reload). Reload value stored in TH1 for automatic restart on overflow — no software reload needed between counts. Demonstrates the difference between manual 16-bit and auto-reload timer modes.

Project 3
Binary Countdown Timer with Interrupt
Interrupt-driven countdown using Timer 0 ISR (ORG 000BH). IE register set to 82H to enable Timer 0 interrupt globally. Counter display updates in the main loop while the ISR handles timing — demonstrates the event-driven interrupt model versus polling.

Project 4
Additional Assembly Project (Project 3)
Further register-level 8051 programming covering PSW flag manipulation, conditional branching, and additional I/O port interfacing techniques developed throughout the CTEC 350 course.
Quick Python script to log cell voltages from a CSV export, flag cells below threshold, and output a plain-text service report. Built to speed up pre-session battery checks at RPM.
Scans a local subnet with socket pings, pulls hostnames via nslookup, and prints a tidy table of active devices. Used it during lab setups at NYIT to confirm switch ports before imaging.
Random-delay LED lights up, user presses a button — reaction time prints to Serial Monitor in ms. Built as a warm-up project learning interrupt handling and millis() timing in embedded C++.
Script that takes system size (kW), avg daily sun hours, and local utility rate — outputs estimated annual production and savings. Used to sanity-check Aurora Solar reports before client delivery.
Single-page browser app with a step-by-step checklist for assembling and configuring a PC — POST test, driver installs, network join. Keeps a completion log saved to localStorage. Used for client builds.
ESP32 pulls CPU load and temperature from a local PC via a tiny Python socket server, displays live stats on a 128×64 OLED. Born from wanting a physical readout on my desk during lab sessions.
Four distinct portfolio design concepts built from scratch — Editorial Amber, Plumeria Pink, Tropical Pill Nav, and Coastal Turtle. Each has its own color system, typography, canvas animation, and layout.
Qualifying data, 3-driver telemetry overlays, sector comparisons, standings, and live 2026 timing via OpenF1 API. Currently being reworked — FastF1 Python backend, real lap-by-lap telemetry, two-column desktop layout.
