The Midcoast Mini Maker Faire ain’t your grammy’s craft show. It’s much, much cooler. How cool? How about the Icycle Bicycle (an ice-cream maker powered by pedals), or underwater robots, or the latest innovation in space-suit gloves? All sorts of geeky/neat stuff with be on display at the Camden Public Library (55 Main St., Camden) from 11 a.m. to 3 p.m. It’s free. librarycamden.org. And tonight, out-there composer/musician Thomas Kozumplik unleashes “TommyTom’s Time-Machine,” the first in a three-part series of monthly performances melding ancient instruments and modern technology to make genuinely groundbreaking sounds, at Portland Yoga Studio (616 Congress St., Portland). The 8 p.m. show also includes work from his other projects, Loop 2.4.3. and Clogs. Suggested donation: $10. 807-3807. portlandyoga.com.
