Introducing The VolksEEG Project
Introduction
The VolksEEG project is an open-source project with the goal of creating an electroenchephalogram (EEG) machine, fully cleared by the FDA for standard clinical use. All designs will be freely available for others to manufacture.
The project was founded by Alan Cohen, a medical device systems engineer with an electrical engineering/software (EE/SW) background in Boston, USA, and Dr. Bryan Glezerson

Review: Prototype to Product
Prototype to Product: A Practical Guide for Getting to Market, by Alan Cohen, is a must-read for anyone involved in product development, whether in a technical, management, or executive role.
I was reminded of it by Cohen's recent episode on Embedded.fm, 388: Brains Generate EMF, which is worth listening to a couple times through, especially if you're interested in medical device development. And in fact his first episode there,
Learning From Engineering Failures
Contents: IntroductionI'm an informal student of engineering failures. They guide a lot of my attitude and approach towards engineering.
This is rooted in two of my favorite quotes:
- George Santayana: Those who do not remember the past are condemned to repeat it.

Acceptance Tests vs. TDD
Contents:My Guiding Principles As An Engineer
These are my guiding principles as an embedded systems software engineer, forged over 40 years of experience. They shape the way I work and approach problems, and maintain my attitude in the face of adversity.
You may find them useful as well, whether working as a developer, a manager, or an executive, alone or on a team, when things are going well, and when they aren't.
They're a combination of favorite quotes and my own bits of derivative wisdom I've sprinkled...
Dumb Embedded System Mistakes: Running The Wrong Code
ContentsAdvice For High School Students
ContentsYour Career Archive
Clive Maxfield and Adam Taylor recently published a series of blog posts about how to get and keep an engineering job, discussing preparation in high school through early career stages. I've just started a new job, and wanted to add some information on a particular aspect of changing jobs, the employment background check.
Over the past 10 years, I've changed jobs several times. Three of those jobs, including the most recent two, have required background checks as part of...
Simple Automated Log Processing
Text log data offers a wealth of information from an embedded system. At least during prototyping and development phases, most systems have some kind of serial log output, or use semihosting methods to log to a serial output channel in a debugger. Then you can capture the logs to a file.
The problem is that they tend to accumulate large volumes of data. Logs can be many thousands of lines long, especially when you run long duration tests. Finding information and evaluating trends in the...

Examining The Stack For Fun And Profit
Well, maybe not so much for profit, but certainly for fun. This is a wandering journey of exploration and discovery, learning a variety of interesting and useful things.
One of the concerns with an embedded system is how much memory it needs, known as the memory footprint. This consists of the persistent storage needed for the program (i.e. the flash memory or filesystem space that stores the executable image), and the volatile storage needed to hold the data while executing over long...

Review: Project Management for the Unofficial Project Manager
Software development projects are notorious for having problems. Late, over budget, not working properly, making people's lives miserable all around. Embedded systems add the further complication of hardware to that.
How many of us have lived through problematic projects? Hopefully some of them have at least been ultimately successful to make all the suffering worth it in the end, but there are plenty that haven't.
I don't consider myself a project manager, or a manager...

Six Software Design Tools
Contents: IntroductionHere are six tools to help you with software design. The first two are very simple, almost deceptively trivial, while the last four are more involved. They apply universally, to all types of software, all types of systems, and all languages. This is part of good engineering discipline.
At face value, this is just a bunch of acronyms,...

The Self-Directed Virtual Internship
A number of my LinkedIn connections are college and university students at the bachelor's, master's, and doctoral levels, from all over the world. The embedded systems community constantly amazes me.
One fallout they're experiencing from COVID19 is cancellation of summer internships. This is very unfortunate, because an internship represents maintaining educational momentum and preparing for launch of a career with a taste of the real working world, along with some financial...
Some Advice For Working From Home
The other day I posted a short video of my WFH setup (and here's a May 1st upgrade). Today I have some general advice for WFH for people who are new to it.
I've been doing it randomly for the past 5 years, usually just one or two days a week here and there. Now it's a full-time thing for the duration of the coronavirus. So some of this wanders afield a bit, settling in for the long haul.
Some of it is based on things I've built up over years. It's unreasonable to expect that...
