Electronic and Technical Arts

The Electronics and Technical Arts studio at BARN is generally modeled after a “makerspace” or “hackerspace”. We are interested in rapid prototyping and fabrication, 3D printing, electronics circuits, robotics, embedded electronics, and software. We like to experiment, and try new things.

Some of the equipment we have:

  • Full Spectrum 45 Watt CO2 laser cutter
  • Ultimaker 2+ 3D printer
  • Prusa i3 Mk2 3D printers (currently 2)
  • Four-channel Digital Oscilloscope (Rigol DS1104Z)
  • Microscope and hot air soldering station
  • Lots of miscellaneous hand tools

New members can receive orientation and training on equipment during our posted open studio times. Open studio times are also a great opportunity to stop by and check things out as a non-member. For non-members, there is a $10 drop-in fee to use tools.

You can contact us with questions here.

Laser Cutter

Our laser cutter is a Full Spectrum Gen 5 Hobby model, with a 45 Watt tube. It is generally capable of cutting wood products up to 1/8” and acrylic (Plexiglas) up to 1/2”. It can also mark many other materials. Its cutting capacity is approximately 20” x 11-1/2”.

The Laser is available for use during open studio times, by trained BARN members.

There is some support from the company website, including tutorials and manual

We usually use the free program Inkscape to design for the laser.

Makercase is a tool for generating box plans.

3D Printer

Our main 3D printer is an Ultimaker 2+. Users are responsible for providing their own filament, although there may sometimes be some on hand. Filament should preferably be true 2.85mm. PLA, Nylon, and PETG are all acceptable materials. We have had good results with ProSpec and MeltInk brand PLA filaments from Amazon or ProtoParadigm.

Our other 3D printers are Prusa i3 Mk2 models. These require 1.75mm filament.

Use Cura to slice your model for printing. The default profile for the Ultimaker 2+ is fine, but for the Prusa’s the default profile needs changes, we’re still fine-tuning it though. Stop by during “open studio” times for the currently profile settings.
