After the November Toy Drive, Signal Centers will host a workshop to teach participants how to adopt the toys and make the switches.  The 3-part workshop will include basic soldering and tool safety with practice on scrap wire; adapting a toy from start to finish; and making switches for the toys.  No experience is necessary.  This workshop is ideal for families wanting a volunteer project, organizations wanting a team-building activity or families/caregivers of a child with a disability. 

In 1991, Signal Centers opened Assistive Technology Services, providing technology services to ten counties in Southeast Tennessee. The focus of Signal Centers' Assistive Technology (AT) Services is to promote the incorporation of technology in the lives of people with disabilities. AT Services uses technology to empower people with disabilities, to give them control and to provide them with choices in all aspects of their lives.

The AT Center is one of five Assistive Technology Resource Centers in the Tennessee Technology Access Program (TTAP). It is also one of forty certified Assistive Technology Resource Centers in the national Alliance for Technology Access (ATA).

We provide demonstration, reutilization and design, device loan and training services for individuals, caregivers and professionals.
