We are developing hardware and software tools to assist in the process of “debugging” e-textile circuits. E-textile debugging presents a unique set of constraints due to the flexible and fabric-based nature of project materials.
This is a National Science Foundation-sponsored project: Award # 1742081: Collaborative Research: Debugging by Design: Developing a Tool Set for Debugging with Electronic Textiles to Promote Computational and Engineering Thinking in High School
This is a logic probe for e-textile makers that enables them to easily test and debug their code and circuitry without a multimeter.
A regular multimeter can be difficult to use while your wearable or e-textile is moving or on your body. This device solves that issue, acting as a lightweight and dependable voltage meter that can be easily added to most projects.
The ThreadBoard is a magnetic breadboard for embedded computing that allows for the rapid prototyping of e-textile circuits. The motivation behind the ThreadBoard is to develop a tool that will adapt to the unique set of constraints that e-textile creators face when fabricating an e-textile project.
The Circuit Playground Extension is a tool that enables the user to design e-textile circuitry with debugging in mind.
Circuit Check is a debugging system for testing hardware components. It allows the user to easily check onboard and external sensor information; drive onboard and external actuators such as LEDs; and set pin states and PWM – all without the need to compile code after the initial setup.
