Frequently asked questions
When will I get my order?
If the TI-84 calculators and Arduino components are in stock, your order will be assembled and shipped as soon as possible. If any parts are unavailable, we will source them from our suppliers and ship your order promptly once everything is ready.
How are your products manufactured?
We work with pre-owned TI-84 calculators that we carefully source, then modify in-house by installing Arduino-based hardware, programming the system, and fully testing each unit before shipment. Every calculator is assembled and verified by us to make sure it functions properly before it reaches the customer.
How does the TI-84 work?
It works like a standard TI-84 calculator, with added AI capabilities. Simply connect it to your phone’s hotspot, run the program, and get step-by-step help or answers directly on the screen.
You can also reset the RAM at any time to return the calculator to its original state, and easily reinstall the program with a simple command when needed.
