EduVIS Spectrometer

Development is currently paused.

Project Overview

The EduVIS is an educational spectrophotometer I helped design and develop at Paxia LLC, where I serve as one of the co-founders and the lead hardware designer. This versatile instrument was created to make advanced spectroscopy accessible to educational institutions, with a focus on simplicity and affordability without compromising measurement quality.

Key Features

Wavelength Range: 400-700 nm covering the visible spectrum
High Resolution: 0.3 nm for accurate measurements
Fast Sampling: Less than 2 seconds per measurement
Wireless Connectivity: Bluetooth Low Energy (BLE) for easy device pairing
User-Friendly Interface: Cross-platform mobile application
Durable Design: Metal frame built to withstand classroom use
Complete Package: Includes 3 cuvettes and a protective Pelican case

Technical Implementation

Hardware Development

The spectrometer was designed using a combination of modern tools and techniques:

PCB Design: KiCAD for electronic schematics and board layout
Enclosure Design: Fusion360 for the precision metal enclosure
Microcontroller: ESP32 for processing and wireless communication
Firmware: Developed in C with optimizations for power efficiency
Optics System: Custom designed light path with diffraction grating

Software Development

Mobile Application: Cross-platform app for iOS and Android
Data Processing: Real-time spectral analysis algorithms
Experiment Library: Pre-configured setups for common educational experiments (coming soon)
