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.”
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.
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).
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 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).

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.
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.

Every week, Adafruit masterminds Limor Fried and Phil Torrone host a live on-air Show-and-Tell, where folks can join in and share the details of specific projects they're working on. Last week, Adafruit community member Dan shared his hard-learned tips and tricks for milling small wood pieces on an Othermill.
In January of 2016, University of California San Diego opened the doors to their nearly 3,000-square-foot makerspace classroom called the EnVision Arts and Engineering Maker Studio. Fully stocked with a wide variety of design, fabrication, and prototyping tools, EnVision is housed in UC San Diego’s Structural & Materials Engineering building.
A TEAM THAT SHIPS TOGETHER STAYS TOGETHER
As of today, we are finally caught up with our backlog and shipping Othermill Pro orders when they are placed. It seems like a small shift, but this is huge for us. Each time you make a new version and put it out into the world, it is just like launching a totally new product. Here are some cold hard facts about how long each iteration took.
