About Me

I have a background in software development, mostly in C/C++ and Java.  I spent my career building software and teaching software development best practices.

In 2013, I purchased an Arduino Uno board just for fun.  I wanted to do some embedded systems programming, which I never did at work.  Big mistake!  🙂  I purchased sensor shields and breakouts that can be found on eBay and I created some projects. But, if using an Arduino is nice for prototyping, it’s not convenient as a permanent solution because it’s too easy to disconnect a wire (not to mention the cost).  I looked for an alternative and found smaller Arduino boards (Arduino Pro Mini) that could easily be fixed on a breadboard, for prototyping and the on a PCB as a permanent solution.

But, wait!  What’s a PCB?  I ended up reading books about how to design my own circuits and PCBs. I also learned how to use a software called Eagle to design my boards. Then, I started etching PCBs and learned how to solder through-hole components.  I soon realized that even Arduino Pro Mini boards were too expensive and were doing too much for most of my projects.  This is when I started using Attiny micro-controllers directly.

Using Attinys was a different beast and brought it’s own set of challenges including the program (firmware) limited space (1Kb to 8Kb).  After some research, I learned that I could accomplish the same things with much smaller C programs by using the Attiny registers directly.  Something else to learn about!!!

In the mean time, I purchased a CNC machine (ShapeOko 3).  After some experimentation, I realized I could stop using chemicals to etch PCBs by using my CNC instead.  It toked a lot of experimentation but I am now able to produce PBCs in a reliable manner.

Now, I am about to start experimenting with SMD components.  I just acquired a T962 PCB reflow oven and a whole bunch of SMD components.  Once I receive everything, I will definitively start posting about that!

I hope you will enjoy my site.  My goal is just to share about what I learned so it can help others in their journey.  I would also enjoy learning new stuff from you!

    I had a question regarding the “Useful Links” page on your website. Are you accepting suggestions for the page?

    If you are, I would like to suggest adding Maker Pro under the “Arduino” header. They are an active, open source platform for maker projects much like Hack A Day. These projects are centered around Arduino, Raspberry Pi, Intel Edison, home automation and more. And better yet, the content is completely user generated. Here is the URL for their website if you would like to have a look:


    Let me know what you think of this suggestion or if you need any additional information!
