This blog will help you build your own, low cost 3-axis motion sensor using Raspberry Pi and Invensense MPU6050.


The Dilemma of Unwritten Requirements

Jason Sachs October 25, 20151 comment

You will probably hear the word “requirements” at least 793 times in your engineering career, mostly in the context of how important it is, in any project, to agree upon clear requirements before committing to (and hastily proceeding towards) a deadline. Some of those times you may actually follow that advice. Other times it’s just talk, like how you should “wear sunscreen when spending time outdoors” and “eat a diet low in saturated fats and...


Requirements, Specifications and Tests

Kenny Millar June 20, 2013

As a freelance developer of all things embedded, it's important that right through a project everyone involved knows what is expected, who is responsible for delivering, and how to confirm that what is delivered meets the customers expectations.

I have a tried and trusted method that works for me each time, is flexible enough to deal with feature-creep and solid enough to give the client that warm fuzzy fealing that they crave.

I've dound that this method of working has in the past been...


A Working Real Time Clock (RTC) Implementation

Dr Cagri Tanriover March 25, 20132 comments

In one of my projects, data captured from various sensors had to be time stamped in the YearYear/DayDay/MonthMonth, HoursHours:MinutesMinutes:SecondsSeconds format. My initial thought was because there was already a GPRS modem in the system, I could simply configure it to use the network time delivered by the base station when it fired up. Once the GPRS module started up and retrieved the correct time, I could then invoke a simple AT command to read the time stamp into the microcontroller....


Embedded Software Creation II - European Normative & Legislation

Dr. Maykel Alonso December 20, 20116 comments

In this post I will explain the European Normative. I will answer the main questions and I will be open to answer all the doubts any of you could have. Please leave a comment and I will answer if i could.

Why I need to look and accomplish some standards? 

The main reason is if you want to comercialize the product in the European Union, if exists any European Directive that cover the product, the product must be marked with the CE mark. For USA it work in the same way by the...


Complexity in Consumer Electronics Considered Harmful

Jason Sachs October 1, 20111 comment

I recently returned from a visit to my grandmother, who lives in an assisted living community, and got to observe both her and my frustration first-hand with a new TV. This was a Vizio flatscreen TV that was fairly easy to set up, and the picture quality was good. But here's what the remote control looks like:

You will note:

  • the small lettering (the number buttons are just under 1/4 inch in diameter)
  • a typeface chosen for marketing purposes (matching Vizio's "futuristic" corporate...

Patents and the little guy working at home

Mark Browne April 11, 20191 comment
There are pluses and minuses to having patents. As it stands now the patent system is horribly broken and not doing what the founders intended when they set it up.I have some patents through work and it does look nice to see my name on the patent database. It's kinda like wetting yourself in a dark suit - it gives you a warm feeling but nobody notices.Don Lancaster makes a compelling argument that for the little guy it’s best to avoid the whole mess to the degree possible.

Unmanned Ground Vehicles - Design Considerations for Snow and Cold Environments

Ed Nutter December 27, 2016

It's that time of year when the white stuff falls from the sky across the US, and with it comes lower temperatures. These conditions must be taken into consideration when designing a vehicle for outdoor use.

A few definitions from wikipedia:

Flurry: light, brief snowfall

Snow shower: intermittent snowfall

Light snow: over 1km visibility

Moderate snow: 0.5 to 1km visibility

Heavy snow: less than 0.5km visibility

Blizzard: lasts 3 hours or longer, sustained wind to 35mph, visibility...


3D printing for embedded development

Ido Gendel February 19, 2024

Used mostly for creating little plastic objects, the desktop 3D printer is not an obvious addition to the embedded developer's toolbox. However, if you're looking for more reasons to get one, or already have one that's mostly gathering dust, here are a couple of embedded-related ways to get more value out of it.


Embedded Systems Co-design for Object Recognition: A Synergistic Approach

Charu Pande November 4, 2023

Embedded systems co-design for object recognition is essential for real-time image analysis and environmental sensing across various sectors. This methodology harmonizes hardware and software to optimize efficiency and performance. It relies on hardware accelerators, customized neural network architectures, memory hierarchy optimization, and power management to achieve benefits like enhanced performance, lower latency, energy efficiency, real-time responsiveness, and resource optimization. While challenges exist, co-designed systems find applications in consumer electronics, smart cameras, industrial automation, healthcare, and autonomous vehicles, revolutionizing these industries. As technology advances, co-design will continue to shape the future of intelligent embedded systems, making the world safer and more efficient.
