The San Antonio Public Library will host the first-ever Mini Maker Faire on Saturday, Oct.17 from 11 a.m. to 4 p.m. at Central Library. Part science fair, part county fair, and part something entirely new, the faire is an all-ages gathering of tech enthusiasts, crafters, educators, tinkerers, hobbyists, engineers, science clubs, authors, artists, students, and commercial exhibitors.
