The Store Is Always Open

My online store is open now and forevermore. Shipments are going out on time. I will update you here if there are any expected shipping delays, such as me being out of the office, asleep or under the weather.

At the moment, I am updating some of the back-end stuff on the store web page. If it gives you any grief, please contact me directly and I will be happy to take care of you and your order personally.

New Product: 12 LED circle

12LEDcircle - Click for larger, more detailed image
Today I’m happy to announce a new addition to my blinky LED kit line-up, the aptly-named “12 LED circle”, or 12LEDcircle for short. It’s a small, round PCB with 12 bright blue LEDs around the edge. It comes with a pre-programmed microcontroller that lights up the LEDs in various mesmerizing patterns. You can see a demo of the various blinky modes on my YouTube channel.

The assembly instructions, schematic and source code are all available as well.

Kits are in stock and ready to ship today for $12.95.

A Tiny Adventure

The store will be closed for a week starting today, 12 July 2016 until 19 July 2016. I will be off on another tiny adventure to a faraway land. You can still email me at but it might take me a while to get back to you. I will most likely not be able to receive phone calls, however.

Back from Adventures!

OK, I’m back now. Wow, what a trip! I traveled to three continents (counting this one) and got to meet lots of interesting people.

The store is back open again. Shop to your heart’s content!

New products are on their way. Your old favorites are here, as well. Additionally, I’ve upgraded the web site to be encrypted by default, so all transactions (even your browsing) should remain relatively confidential now.

It’s good to be back. The yard is showing some signs of neglect, but hopefully I’ll get that sorted out shortly.

Do drop me a line and let me know how you managed to get along without me for so long!

Off to Adventures!

I’m leaving the country for an unspecified amount of time in pursuit of challenging adventures. Unfortunately, I won’t be able to process any orders during the duration.

But don’t worry! You can still purchase my products from BG Micro, the Maker Shed, Sparkfun Electronics and Solarbotics in Canada. You can also still buy my books on Amazon.

More details as the adventure unfolds!

I Wrote Another Book

Building Your Own Electronics Lab

Building Your Own Electronics Lab

I wrote another book.  This time it’s about building your own electronics lab, titled Building Your Own Electronics Lab.  It gives the reader a gentle introduction to electricity and electronics and how to safely learn and play with them.  Basic tools and components are discussed and some simple starter projects are presented.  The main idea that I tried to put forward is that the electronics hobby is fun.  It’s also fun to share with others.

Both paperback and e-book versions are available from, or find it at your favorite bookseller using the ISBN 978-1430243861.

My New Phone Number is (330) 732-5307

Effective immediately, my new phone number is (330) 732-5307.  Give me a call sometime and let me know what’s going on.

Lux Spectralis 2 Now Available

I’ve updated the popular Lux Spectralis kit.  The circuit still does exactly the same thing (blinks multi-colored LEDs).  I simplified the whole thing and reduced the component count.  This will make it easier to assemble.  You can download your own copy of the assembly instructions.

The new Lux Spectrlais 2 kit uses three separate LEDs for the red, green and blue color channels.  This will make it much easier to modify for custom color combinations.  The new PCB is a little bit smaller than the previous version.  It uses electroless nickel immersion gold (ENIG) plating on all the electrical contacts, which has its own advantages, electrically, but I did it because it’s more beautiful and contrasts well with the black solder mask.

The kits still comes with a 3xAAA battery holder with a built-in power switch.  The lighting modes are identical to the previous version.  The price remains the same.

I Wrote a Book

Over the summer, I wrote a book about Arduino internals, called Arduino Internals. It is being published today by Apress. It has a lot of detailed information about Arduinos as well as Atmel AVRs. There are several projects in the book that illustrate some of the topics. It’s a paperback book that runs to just over 350 pages. There’s also an “ebook” available in several popular formats.
You should be able to buy your very own copy today from Amazon with a nice little discount and free Super-Saver shipping. You can also go to your favorite book seller and buy a copy. Just use the ISBN number 978-1430238829. To buy the ebook, go to the book’s page on the Apress web site,
This was a very exciting project for me. It’s my first book. I hope you enjoy it.

Update:  The publication date has been bumped to November 16, 2011.  I don’t know why.
