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).
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.
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.
We recently heard from one of our intrepid community members, Dave Cox, who reached out to share a guide he's written about using the Othermill and Otherplan to make mechanical prototypes using Altium. Dave is an engineer at SeeScan, a company that specializes in designing, manufacturing, and supporting diagnostic and utility-locating equipment.
After we put the finishing touches on each lovingly handmade Othermill in our Berkeley factory, we send it off to its new home, knowing it'll be making amazing things in the hands of our brilliant community members. The fun part for us is seeing what our Othermills have been up to since they flew the nest. You all inspire us!
OMC community member Duncan Haldane has built the world’s greatest jumping robot. No, seriously. Haldane’s bot is named Salto (short for “saltatorial locomotion on terrain obstacles”), weighs 100 grams, is 26 centimeters tall when fully extended, and can jump to 1.007 meters. Impressive, to say the least.
