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.

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.

Boost Your Boards: Speeding Up PCB Prototyping with Engraving Bit Isolation Milling

Posted by Ezra Spier on May 9, 2016 3:35:36 PM

 

What if I told you that you could mill precise PCBs in a fraction of the time, increase trace precision, and essentially eliminate the experience of breaking bits? Starting with version 0.27, the Otherplan Public Beta makes this possible with a new feature: engraving bit isolation milling.

How to Make PCBs On a Desktop CNC Mill

Posted by Owen Smithyman on Jan 22, 2016 10:30:00 AM

This post provides an overview of how to design and prototype printed circuit boards on a desktop CNC mill. Most students do not have access to a CNC mill in their electrical engineering or electronics classes. In most classes, students make circuits using breadboards, which allows them to make connections by plugging wires and components into a grid. This method is great for very simple circuits, but it quickly becomes messy as circuits increase in complexity, to the point where it becomes very difficult to troubleshoot.
