Math should open doors, not close them. Yet for millions of visually impaired and blind students and adults, something as basic as a calculator can be a barrier instead of a tool.
STEM Engine is building a full line of LOW COST, fully functional braille calculators designed specifically for visually impaired and blind users, from early learners to advanced STEM students. These calculators are tactile, high-contrast, Braille-enabled, and include clear audio output in both English and Spanish (My First Talking Calculator). They work independently, right out of the box.
We are raising $50,000 to bring all three calculator models, from basic (My First Talking Calculator ) to scientific, into production so that visually impaired and blind learners can access math with confidence, independence, and dignity.
The Problem
For many visually impaired and blind students, math tools are either inaccessible, overly complex, or prohibitively expensive.
In classrooms, testing environments, and at home, students often rely on:
Outdated devices that do not meet modern learning needs
Workarounds that depend on constant assistance
High-cost specialty tools that are out of reach for families and schools
This lack of accessible, affordable tools limits independence and sends a quiet but damaging message about who does not have access to math and STEM learning.
The Solution
STEM Engine is creating a tiered line of accessible calculators that grow with the learner:
One-digit calculator for early math
Three-digit calculator for more advanced operations
Scientific calculator for secondary education, college, and workforce use
Each calculator is designed with:
Braille labeling
High-contrast tactile buttons
Clear audio output in English and Spanish
Independent, out-of-the-box usability
These tools are built to support independence, confidence, and full participation in math and STEM, without requiring constant assistance or additional technology.
Why This Matters Now
Access to math is access to opportunity.
As education, testing, and workforce pathways increasingly rely on quantitative skills, visually impaired and blind learners cannot afford to be left behind due to inaccessible tools. Early access builds confidence. Continued access supports persistence. Advanced access opens doors to college and careers.
This project is about more than calculators. It is about equity, dignity, and ensuring that visual impairment does not limit potential.
How Funds Will Be Used
Your donation will directly support continuing
- Refinement and development of three calculator models
- Engineering and software development for audio and accessibility features
- Accessibility testing with visually impaired and blind users
- In-house pilot manufacturing using 3D printing
- Materials and components for initial production runs
- A small production and assembly workspace
- Outreach to schools, families, and organizations serving the visually impaired and blind communities
We are committed to transparency and will provide donor updates as milestones are reached.
Who Is Behind This
Stem Engine is a 501(c)(3) nonprofit founded in 2025. The team brings together experience in engineering, software development, and operations, united by a mission to expand access to STEM through practical, human-centered design.
We believe accessibility should be intentional, affordable, and built in from the start.
Call to Action
