Twenty-two makers will present their gizmos, contraptions, crafts and obsessions at the fourth Midcoast Mini Maker Faire Saturday, Sept. 10, from 11 a.m. to 3 p.m. Makers will be exhibiting their projects in the Camden Amphitheatre and Camden Public Library, off Atlantic Avenue.

Several makers are returning with updates on their previous projects, and many are new this year. As always, there will be many hands-on makers, offering attendees a chance to create on the spot.

The Farnsworth Art Museum, a mainstay at the event, will present a community art project. Using nothing but plain masking tape, participants will be able to contribute to a large piece of improvised sculpture.

Elizabeth Lally will show her mandala stones and guide participants of all ages to paint their own. Three-dimensional texture is created by applying layers of acrylic paint; circles can blend or stand alone. Using tiny brushes, fairgoers will create symmetrical masterpieces using stones collected from local beaches.

New this year, but familiar to Penobscot Marine Museum attendees, will be the opportunity to have an authentic tintype photograph taken. Cole Caswell makes tintype portraits, a popular form of photography during the Civil War. The process involves wetplate collodion chemistry and forms an image on a sheet of blackened metal. Caswell, adjunct faculty researcher at Prescott College and adjunct faculty at Southern Maine Community College, has brought his portable tintype set-up the Midcoast several times this summer.

The Midcoast Mini Maker Faire is a collaboration between Camden Public Library, Midcoast Magnet and the Steel House; and is sponsored in part by Make Magazine. Admission is by suggested donation of $2 per person, $5 per family. The annual event offers everything from hands-on to high-tech and is very family-friendly.
