Final Project - Smart Tool Cabinet with RFID Tracking#

I build a Smart Tool Cabinet that tracks tools using RFID cards for access control and mini switches with individual microcontrollers in each tool slot to detect when tools are removed.

What It Does#

RFID Access Control - Each person gets an RFID card to unlock drawers they’re trained to use
Tool Tracking - Mini switches in each tool slot log when tools are taken and returned
Automatic Alerts - System alerts if tools aren’t returned on time
Usage Logging - Tracks who used what and when

No more missing tools! The cabinet knows everything.

Who It’s For#

This Smart Tool Box is designed for anyone working in a collaborative maker space — whether it’s a Fab Lab, school workshop, university makerspace, or community workshop. It’s particularly valuable for:

Lab Instructors and Managers: To track tool usage, monitor availability, and maintain an organized workspace
Students and Makers: To easily access tools, know when they’re available, and contribute to a better-organized lab
Tool Owners: To keep track of their equipment and prevent loss or misuse
Facility Coordinators: To gather data on tool usage patterns and plan maintenance schedules

Components#

Hardware:

RFID reader & cards
Mini switch sensors (one per tool slot)
Solenoid locks
XIAO ESP32C6 and CH32V003J4M6 microcontrollers
Custom-fabricated enclosure

Software:

RFID authentication system
Switch monitoring & data logging
Alert system
Mobile App (IOS and Android) for notifications and tool status

Why This Project?#

It solves a real problem (tools going missing), teaches me RFID + electronics + microcontrollers, and is actually feasible to complete. Win-win! 🚀

Tools & Skills I’ll Learn#

✅ RFID Technology - I’ve never done this before, so that’s gonna be cool to learn

✅ Sensor Integration - Reading multiple sensors and processing the data

✅ Electronics & Circuits - Wiring up solenoid locks and buzzers

✅ Microcontroller Programming - The actual code to make it work

✅ 3D Design & Fabrication - Designing and fabricating the enclosure

✅ System Integration - Making all these different parts work together

✅ Database/Logging - Keeping track of all the data

Timeline & Breakdown#

This is lowkey a pretty big project, so I’m breaking it down:

Challenges I’m Expecting#

Power management - All these components use power, gotta make sure it’s efficient
Durability - It’s gonna be used a lot, so it needs to be tough
Cost - All these sensors and components aren’t cheap lol

But honestly, that’s what makes it fun. Solving hard problems is what engineering is about!

Why This Is My Final Project#

At the end of the day, this project is:

✅ Feasible - I can actually finish it in time

✅ Complex enough - Uses multiple technologies and skills

✅ Practical - It solves a real problem that people face

✅ Impressive - Looks cool and works even cooler

✅ Educational - I’m gonna learn SO much doing this
