Othermill PCB Milling and Masking Tutorials from SAIC

Posted by Goli Mohammadi on Apr 18, 2017 9:04:00 AM

Founded in 1866, the School of the Art Institute of Chicago (SAIC) is not only one of the most well-respected art and design schools in the U.S., but it’s also known for its forward-thinking interdisciplinary curricular offerings and for pushing the envelope on what education in the arts can look like. We’ve previously covered their use of desktop manufacturing tools and are proud that Othermills are among their robust tool offerings.

High School Robotics Team Uses Othermill to Mill PCBs and Salvaged Aluminum

Posted by Goli Mohammadi on Apr 4, 2017 9:55:00 AM

By day, Bloomsburg, Penn.-based educator Tom Gill teaches physics and astronomy at Central Columbia High School. After school, he mentors two robotics teams: the Jaybots and the Jayborgs, the names a nod to their school mascot, the blue jay. A year ago, Tom added an Othermill the teams’ tool arsenal. He recalls, “I was inspired to get one because of the variety of tasks that it can perform and how it complements our other equipment, such as laser cutters and 3D printers. Another big factor was its small footprint and relative quiet operation, so it can be run during the school day next to the library.”

Why Burn-In and Break-In Processes Are Essential

Posted by Sam Prest on Mar 21, 2017 9:30:00 AM

In order to ensure that a product works well straight out of the box and performs reliably over its lifetime, it's important to consider a "break-in" or "burn-in" process for certain critical components. The difference between these two processes is subtle but important to understand when evaluating how and why to implement them. Both can play a critical role in maximizing lifetime and minimizing failures, ensuring a positive experience for end users.

UC Berkeley's Jacobs Institute Invites Innovation Through Interdisciplinary Programming

Posted by Goli Mohammadi on Mar 20, 2017 6:12:55 PM

In August of 2015, UC Berkeley opened the doors to Jacobs Hall, home of the College of Engineering's Jacobs Institute for Design Innovation, described as their "interdisciplinary hub for learning and making at the intersection of design and technology." The 24,000-square-foot building houses a wide variety of creative spaces and tool labs, including individual dedicated labs for wood fabrication, CAD/CAM, electronics, A/V production, and advanced prototyping, as well as all-purpose makerspaces (with Othermills proudly among the tool offerings).

Intro to Electronics Product Design Part 2: Electronic System Architecture

Posted by Janet Stillman on Mar 14, 2017 9:00:00 AM

In the first installment of this five-part series, we worked through the process of defining the early requirements for our system: a convenient solar oven. In this second installment, we run through the steps of designing an electronic system architecture, with a heavy focus on the specific design of the solar oven controller. We’ll attempt to meet all the requirements for a test platform that were elaborated on in the previous article.

Winter Othermill Project Roundup

Posted by Amber Hancock on Feb 28, 2017 6:18:00 AM

Winter is almost over, and that means it's time for another Othermill Project Roundup! Throughout the season, we've collected quite a few Othermill-made creations from community members near and far, and we're excited to share them with you. Projects range from 2D engravings made using SVGs, to both simple and complex PCBs, to 2-1/2D mechanical parts in all shapes and materials (wood, polycarb, and aluminum, just to name a few).

Design for Manufacturing: Can We Mill This Master Cylinder Adapter?

Posted by Sam Prest on Feb 21, 2017 9:18:40 AM

The part in question, with tooling, rendered in Fusion 360.

People often contact us asking if a specific part they've designed can be made with a desktop CNC. In this article, we use one example part to show you how to determine if a part can be milled and what size tools and raw material we’d need.

Intro to Electronics Product Design: Defining Requirements for a Convenient Solar Oven

Posted by Janet Stillman on Feb 14, 2017 11:04:34 AM

This is the first in a series of five articles that will provide an overview of an electronics system design process, using the example of a solar oven controller. The process described here works for both simple and complex designs. Complex designs usually merit more iterations and more layers of optimization, but the steps are about the same.
