Last weekend I was at the first annual National Maker Faire held at the University of the District of Columbia. It was a relatively large Maker Faire with a lot of interesting projects on display. In addition to individual makers, there were a number of organizations presenting their involvement in STEM education and creation of makerspaces. A number of hackerspaces and makerspaces were attending as well as universities and commercial companies.
Here are some projects I captured on camera:
Mini underwater glider that uses a large syringe as a buoyancy engine.
Submersible made from PVC pipes and simple hobby motors, waterproofed using small plastic canisters and wax.
OpenROV underwater exploration robot (www.openrov.com).
NIST presented a lego "Watt Balance", a weight measurement instrument built as part of educational outreach (arxiv.org/abs/1412.1699).
Louisville Hackerspace had a several-feet-long model rocket on display (www.lvl1.org).
Another group had drawing bots.
There was a continuous 3D printing setup that uses a plastic film as a conveyor belt. The system uses air suction to keep the film stationary during printing (mobiumsolutions.com).
A Benjamin Franklin sculpture assembled from pieces 3D-printed by different individuals (www.wethebuilders.com).
NIH 3D Print Exhange, a biomedical 3D model repository (3dprint.nih.gov).
Samsung ARTIK, a new IoT platform (www.artik.io).
A pick-an-place machine for assembly of surface mount electronic components.
An automated in-house plant growing system (www.growbox.io).
And there were Legos,
and an R2D2.
Here's a link to the official event page listing all makers.
