A sample of Dan's projects that make up OSML
We needed a collaboration space to be the starting point for project design. After researching other solutions, we came up with a design with a semi-circular table with seating for four. Laptops loaded with lots of design software all connect to the big screen through an HDMI switch, so that any laptop can be instantly displayed on the main viewer. The table itself is counter-height, so it’s easy for others to walk up and easily join the conversation. The semicircular table top was cut in a four-foot radius with a hand router and homemade trammel.
We designed a modular reception desk that leveraged existing components (white laminated shelving and whiteboard) which met all functional requirements, including ease of assembly. The logo was cut out of acrylic on our laser cutter. Total project time: three days.
We implemented a “Maker Safety & Operations Certification Program” this year to baseline safety procedures, as well as to encourage members to learn new skills and get their “driver’s license” on more machines. The “big board” is prominently in the reception area and gets lots of visibility. The sign at the top is double laser cut acrylic (clear panel with black letter inserts). The greatest challenge of this build was cutting a four foot sign in a three foot laser cutter.
When we went with our UCSD team to the Mojave Desert to launch their liquid-fueled rocket with a 3D printed engine, we decided we wanted to broadcast the event live on Youtube. To provide dedicated power for our satellite terminal, laptops and webcams, we designed a portable solar generator using off-the-shelf components, welded steel frame, and laser cut instrument panel. We’ve displayed this at two Maker Faires (powering our booth), generating a great deal of interest.
Another quick welding project that has been very useful. The table top is removable, so that in the event of any damage or warping, the wheeled frame can be easily reused.
This was one of our first pieces of equipment, and started as a kit from Probotix. We added drag chain cable carriers, a chip shield, and a custom vacuum shoe system. The chip shield and vacuum shoe parts were CNC cut on the router out of polycarbonate. The green vacuum hose connectors were custom designed and 3D printed for a perfect fit.
Rocket Test/Transport Stand
When the UCSD team was nearing completion of fabricating the Vulcan-1 (a 20-foot tall liquid fueled rocket with a 3D printed engine) in our facility, they needed some type of test rig to securely hold and protect the rocket vertically for cold flow testing (using liquid nitrogen at full system pressure). We suggested a test stand design that could also serve as a shipping rig to protect the rocket in transit. The test/transport stand was fabricated in 14 hours, and worked perfectly for cold flow testing and transport (designed to precisely fit inside a specific U-Haul trailer).
