Joe Grand's CV

Was browsing through Grand Idea Studio website and noticed Joe Grand put up his Curriculum Vitae (CV) for download. Out of curiosity, I did just that and scrolled through his impressive references of qualifications, product portfolio, patents, publications and presentations. Something caught my eyes:

Yep, my sequel book was mentioned in the list of publications, alright! That really make my day...

Trilogy Rhapsody

This post has nothing to do with Elisabeth Haydon's fantasy-romance series, The Symphony of Ages. Rather, it is a celebration of the third milestone in my writing journey since completing the trilogy book to the PCB-RE subject.

Since its release less than two weeks ago, sales of the book is climbing steadily, thanks to the support of readers. And while it is not as abrupt as the sequel book, it too has achieved the No. 1 spot on Amazon's New Book listing much like its predecessor:

Since I started out to write my first engineering book in 2013 while working part-time, the journey has been both challenging and rewarding. Compared to other well-known authors in the electronics discipline, I'm still far from a best-seller author (and I don't think it'll probably happen any time soon...). Still, I'm happy how it has turned out and shaped my appreciation for the many kind people out there who supported me through honest purchase, and in return expressed their appreciation for my engaging and entertaining writing style.

I don't think I will be writing a fourth book on PCB-RE, though I had mentioned one by name out of enthusiasm in an earlier post. Likelihood it'll be put on hold indefinitely unless there is enough demand or request from readers on specific topics of interest, which I doubt since the sequel book already covers much of what tools and techniques there are out there.

So yes, the PCB-RE trilogy works is a complete collection. Perhaps some other engineers may take up where I left off to write their stories and experiences in days to come. I would gladly look forward to that day!

Meantime, I'll be taking a break from writing engineering stuff for now...

Intermission Interview

For readers who wondered about the ScanCAD edition of PCB-RE: Tools & Techniques, it's not been formally published but wholly reserved as a marketing and distribution material for ScanCAD's use. If you managed to get your hands on a copy at one of these exhibitions the company participated, count yourself lucky!

Still, I would like to fill my readers in on a rare email interview I had with the CEO, Bill Loving, the details of which was recorded in the said edition. Here is the transcript:

It's not often you get the chance to talk to someone in the PCB-RE industry with a wide portfolio in terms of exposure and experience, much less to share what they know about their tools and trades. So when I was fortunate enough to get in contact with William Loving, the CEO of ScanCAD International Inc., I was tempted to ask him a few questions:

Me : Why is PCB-RE fast becoming an important and indispensable industry?
Bill : PCB-RE is a respected and much needed business activity in the world today. The tools and processes covered in this book are used globally by many companies and even governments to keep legacy systems running and to recover design data that has been lost.

Me : Do you think PCB-RE tools are susceptible to abuse for piracy purpose?
Bill : Any tool or process can be used for good or bad——it's a function of the user. We like to think that our family of customers are working for the good of all concerned. Sure, there will be some bad apples in the group, but we think it's very, very rare in our crowd. Like your good self, we do not condone illegal or unethical activity that will hurt the interest of any individual, company or organization.

Me : How do you think ScanCAD can benefit the PCB-RE community or companies?
Bill : Having been in the business for 27 years, I see PCB-RE as having a greater impact and positive influence not just on a community or company. Having worked with over 1000 companies across 48 countries, I dare say that our products contribute to the overall well-being of our environment. How, you ask? By keeping legacy systems running, we are extracting more value from our earth's limited resources that have already been used to produce existing electronics and systems. Keeping them out of landfills and in operation is a good steward thing to do. This helps on several levels: reduces the waste, extends use of resource and productivity, reduces air and water pollution since new systems do not need to be made to replace the old, etc. In some cases, a PCB may represent only a fraction of the mass of a large system, yet this PCB can cause the entire system to be scrapped if it can't be replicated. Now, that's a big multiplier effect!

Me : Do you foresee yourself and your team doing PCB-RE for the next 30 years?
Bill : ScanCAD will be around for a long time for sure. Like my colleague Jeff said, we have a dedicated and very capable team, with very good people who strive to be a positive influence in the world and do what's right. If I might add, they are also fun to work with! PCB-RE is a strange little niche——one that we enjoy doing——and one that your book has given us some interesting perspective to look at too.

There you have it! End of intermission.

Trilogy Controversy (Part 3)

The rocky mountains of Colorado are not only a majestic sight to behold, situated in the midst of this scenic setting is the office of a remarkable company that has as its mission to help other companies manage the precious resources of our planet by means of PCB-RE. If you haven't guess it, ScanCAD International is what I'm talking about.

I had not the faintest idea what I was getting myself into when I posted my request via the company's online portal, without any particular expectation that it would get read or answered. Just one day after ScanCAD auto acknowledgement of my request, I received a courtesy email from Jeff Rupert, the director of sales and business development of the company. Wow... did I strike gold or what...? I went into overdrive and wrote a reply with a more formal and detailed introduction of myself and the sequel book I was writing, indicating the areas of interest for the PCB-RE subject.

Jeff, as I began to call him, became interested and got his CEO, Bill Loving, into the picture. Before the dust settled, I was already corresponding with these two heavy weights of the company that has a long history in the PCB-RE practice, with businesses spanning 1000 companies in 48 countries. That's pretty mind boggling to say the least.

Incredibly, Jeff took on the challenge to write the chapter dedicated to ScanCAD's diverse approaches with Bill overseeing the progress. There were discussions back and forth as we exchanged ideas and views on the content and presentation. When the first draft was done, Bill roped in his team of staff to do a thorough proofreading, listing out grammatical and typos so meticulously and stringently you'd thought we were doing audit on a major contractual document! When we were finally done and satisfied, the chapter had not only become the largest in the book but also the most informative on their product ever assembled. It's a win-win situation which both parties could walk away with a great sense of satisfaction.

As usual, I included Bill and Jeff's bios to give them credit with acknowledgement to their staff as well for doing a fantastic job. At my request, they submitted the following portfolio photos:

In appreciation for their tremendous contribution to my sequel book, I produced a ScanCAD edition featuring their chapter as a promotional material which they are free to reproduce and distribute to customers and at international exhibitions.

Bill was kind enough to pen the Foreword to both books and even bulk ordered my books as additional giveaway gifts and bonuses. What set out as a humble request from an obscured author ended up as a windfall that rekindled my passion in writing and confidence in knowing there are people who not only believed in what I do but went further to support my works. I felt deeply indebted to these wonderful people who made writing the book worth every bit of toil and sweat.

And if I may add, they ARE the motivational force behind my writing the trilogy book...

Trilogy Controversy (Part 2)

Sometime in October 2016, I came across a blog that featured a reader's personal review of The Art of PCB-RE, which in my opinion was well-written and fairly objective. On the good side, this is what he wrote:
The book guides you throughout the whole process (of PCB-RE) ranging from all necessary preparations, documentation, tools needed to the final document visualizing the PCB. 
One could argue that it is more a book on Visio than a book on reversing PCBs. It is! But this may perhaps also be one of its strengths as it describes the importance of documentation of the process. I personally find it a good feature being a friend of thorough and easy to read documentation and all. I was thus quite positively surprised to find the extensive documentation used throughout the reversing processing. Many underestimate the importance of documentation, which ironically is one of the reason why this book was written in the first place.
Of course, he did lament the lack of other PCB-RE techniques which would be nice to include in the book (I did mention a little here and there, but The Art of PCB-RE is primarily focused on the manual approach with the average engineers in mind who do not have access to expensive or exotic equipment):
Throughout the book I could however not get rid of the feeling that I wanted more on the PCB reversing techniques... As the author is trying to revive/repair old or undocumented hardware, his process is quite non-destructive. I would like to see some other tricks discussed like for example delayering a PCB, a subject that Joe Grand, a dedicated hardware hacker at Grand Idea Studio writes about in a few great presentations and papers. 
It would also be nice to see more advanced topics like chip-off techniques as this in many cases is a very necessary process in order to be able to both document and interact with parts of the PCB or its components. This is especially true when it comes to BGA – Ball Grid Array components. There is a bunch of cheap and easy to use tools available for this purpose. 
Perhaps way out of scope and a bit too advanced as it may be out of reach for many, it would be nice to mention methods like computer tomography 3D scanning or fluoroscopic techniques available which may be available at university campuses for example.
Well, I heard him loud and clear. Be careful what you wish for! So after some deliberation, I started researching various industry PCB-RE practices and papers. However, real detailed information was rare, if much, to be found online. And though I came from a test engineering background and worked on quite a number of high-end test platforms, to undertake the task of writing a sequel book that covers these PCB-RE methodologies and equipment was way over my head. The more feasible way is to invite experienced engineers to contribute their knowledge in the fields of their expertise.

Since he mentioned the big name of Joe Grand, I decided to take a gamble and write to the kingpin as a first attempt. Guess what? He replied! I simply couldn't believe it... Not only did Joe gave me his permission to reproduce his work, he even vetted and edited the draft and inserted additional stuff to make it more up to date. To top it off, when I asked Joe for a photo to put it in the author bio section of the chapter, this was what he provided:

Was I flattered and floored or what! Of course, there was no prize for guessing which of the two I selected for his bio (grin!). But wait... another big surprise was awaiting me as I pondered and sent out several other invitations...

Trilogy Controversy (Part 1)

George Lucas' iconic Star Wars Trilogy was a big hit with loyal fans the world over, yet there are always critics who read the original novels by Alan Dean Foster and felt strongly that the order of screening did not conform to the actual story line depicted in the books. Lucas, of course, had his reasons to film series IV (Star Wars), V (The Empire Strikes Back) and VI (Return of the Jedi) as the classic trilogy in the pre-90s...

before going on to produce series I (The Phantom Menace), II (Attack of the Clones) and III (Revenge of the Sith) as the next set of Trilogy films.

Similarly, there are people who may be confused about my series of PCB-RE books and perhaps questioned the need for a trilogy instead of just one volume. I'll have to admit that when I first started out to write about this topic, a trilogy is far from my mind, let alone a sequel book. After all, I was just starting out as a relatively unknown indie author with a passion to share my knowledge of 15 years in this niche field, something which other PCB-RE engineers might not want to do or thought it too big an undertaking to worth their time or effort.

To be honest, The Art of PCB Reverse Engineering was published without any fanfare or advertising, and with much trepidation. Thankfully, the response was encouraging with readers who posted their comments on Amazon, one by a J. Ryan I thought was pretty cool:
Reverse engineering PCB's is to electronic circuit boards what hacking is to computer software... something people do, but no one admits to doing it, LOL. 
Mr Ng not only does it, but he lays out a very clear and systematic approach to the entire process. I am self-taught in this field, and it was a real joy to find that someone had actually written an entire book on the subject. I highly recommend this book to anyone interested in the topic.
Even now as I look back, the emotions still run high to know that there are those who do appreciate my hard work, though admittedly I made an early blunder as an inexperienced author to have my book published in full-colors, and consequently priced beyond the reach of the average reader due to high printing cost. I realized it soon enough and went to work to produce a non-color edition that seen a wider readership.

I was quite content to leave things as is and went to write some other genre of books, co-authored with my wife as a way of saying thanks to her for supporting me in pursuing my lifelong writing passion. But as fate would have it otherwise...

Twitter Chatter

Since posting the release of my new book on Twitter, there has been quite some flurry of feedback and following:

It remains to be seen just how well received the trilogy will be as I have not advertised nor promoted it, but simply depend on my loyal readers to spread the word around.

The book is priced affordably and filled with many hand-crafted schematics, drawn and re-drawn using Microsoft Visio for the best visual appeal and overall learning experience, and photos are carefully selected and edited for quality and clarity, coupled with an enjoyable literary style of writing and sprinkled with generous and informative footnotes. It should be worth every cent and time invested.

Into the Final Lap...

Have not been updating my blog for quite a while as I was busy working on the final chapter of the trilogy book. There were plenty of schematics to draw and re-draw just to make sure readers get the best bang for their buck, besides writing the chapter content.

After over a month of hard work, I'm happy to announce that the first draft of the book was finally submitted for proofing with a new book cover artwork (click here for a preview). Keeping my fingers crossed to release it on my 10th wedding anniversary just like my first book four years ago...

Here's another two-page sample of chapter 7:

Do help to spread the news so that people who are interested in this subject will also get a chance to learn the practical aspect of this niche skillset through the contributions of like-minded engineers in the book. Much appreciated!

Tea with Wesly Lo

Met up with Wesly Lo of ABI Electronics for afternoon tea during his business trip here. It was eight years since he came over to my workplace to give training on two testers we ordered from him. Good time catching up. He even bought my book along to get a personal signing. ;)

Quadcopter RE

Completed the chapter on X-Ray PCB-RE about two weeks ago, and now beginning with the chapter on quadcopter RE.  Progress is a bit slow as the Chinese Lunar New Year is just two weeks away and there's a lot of preparation to be done including the annual spring cleaning.

Here's a two-page sample:

While there are four categories of drone types, I will focus on the more popular and widely deployed, the quadcopter. Of course, there are many articles and write-ups on this drone model but I hope to cover more grounds in a systematic way of analyzing its design and parts.

The DJI developed models, in particularly the Mavic Air, is of interest to me. I may not be able to post its schematic diagrams even if I reverse engineer it as there are legal implications if I do. However, a detail inspection into its components should be no issue since there are teardown videos on various drones online.

To be sure, a good understanding of how a commercial drone is put together certainly helps any drone enthusiast appreciate his or her kite better and who knows, it might come in handy for troubleshooting and repair when a fault develops.

Anyway, it's too early to know how the chapter will go. Hopefully, it will be worth my time to write and for my readers to read.

A Shred of Sliver Lining

Continuing from my previous post on the setbacks encountered during the writing of my trilogy book, just when things seem dark and despondent despite my best effort to keep on working, I received an email out of the blue from the president of Elgris Tecnologies, Inc., Igor Luvishis.

He wrote:
First of all, let me thank you for the work you do writing about PCB reverse engineering. As our company is working in this field for many years, I really appreciate your effort.

We got both of your books with the PCB-RE Tools and Techniques book arriving just few days ago. This second book is devoted to the PCB-RE tools available on the market.

It's a pity that Elgris Technologies and our tool (E-studio For Test) are not mentioned in the latest book. 'E-studio For Test' is one of the major tools used by customers for schematic generation from netlists for boards that are being reverse-engineered. 
We will be glad to work with you and to help/participate in any possible way by writing, providing material, sponsoring a section or chapter devoted to Elgris Technologies tools.

We would also be happy to discuss other potential business arrangements with you.

I look forward to your response.

It's definitely a game changer with this surprise voluntary contributor knocking on my door. I see a shred of silver lining breaking through the dark clouds, and that's a good thing indeed!

Setbacks and Crawlbacks

If being a self-publish author is hard enough, imagine trying to orchestrate several contributors for an engineering book!

In the second half of last year, I invited five PCB-RE engineers to contribute a chapter each for my trilogy book. Along the way, one dropped off after showing initial enthusiasm; then another delayed replying my emails and I found out later that his dad passed away and he was having a hard time coping with work. Then near Christmas, the one whom I had such high hope dropped a bomber and pulled out after telling me he's just landed on a new job.

Such frustrations and disappointments are real and can sometimes throw the progress of a book off course or even terminate it prematurely. But I'm not one to give up easily, so in the midst of these setbacks, I have worked doubly hard and come up with two additional chapters to compensate for the loss. The chapter on X-Ray PCB-RE using an Arduino UNO is near completion. Here's a two-page sample:

I foresee the release of the trilogy book will be delayed till early February or perhaps March. Readers of my first two books will have to wait a bit longer, but I'm sure it will be worth the while...

Chapter 5

Another contributor to my trilogy book has submitted his draft chapter for review. Though I will not mention his name at this time, I'll give my readers a clue: he's a PCB-RE engineer from ENA Electronics Inc, who also leads a team doing various RE projects. Here's a two-page sample of his work:

I'm still in the process of vetting and editing, and will be going through the finer details with the writer himself to ensure an accurate representation of what he intends to share in his work experience, while at the same time providing an overall consistent and pleasurable read for potential buyers of this (I hope) much anticipated book.

Once the content of this chapter is incorporated, the trilogy book will hit almost 300 pages. There's one more contributor to go and I shall be giving him a tinker after I'm done with this review task.

Twilight Zone

I'm not referring to the well-known TV series by Emmy Award-winner Rod Serling, who served as host and wrote more than 80 episodes of the original show's 150-plus episode run. But doing PCB-RE does has its strange mix of confusion, frustration, jubilation, and trepidation along the way. In fact, what's left of the unverified portion of a PCB, I called it the twilight zone.

Just as we enjoyed the suspense and surprise ending at each episode (if you're that old like I am, chuckle), there will always be the same feeling when you reach this portion of doing PCB-RE. Then again, where's the fun and challenge if PCB-RE is a piece of cake?

So take it from the man himself:
“You unlock this door with the key of imagination. Beyond it is another dimension: a dimension of sound, a dimension of sight, a dimension of mind. You’re moving into a land of both shadow and substance, of things and ideas. You’ve just crossed over into… the Twilight Zone.”

Tuesday, November 20, 2018


After one year and nine months, and 122 posts later, my blog has garnered over 10,000 views. This is cause for jubilation as another milestone is achieved.

The number of countries has also hit 85 though it slowed down quite a bit since. Of course, it would be nice if readers can help promote and recommend my blog if they have been helped or inspired by what I've written. I'm sure there are still many out there who're interested in the PCB-RE topic but not many are aware of the resources available here and in my books.

Christmas is just slightly over a month away and it's a season to share good tidings of great joy. I'm sure if my readers can help some to find what they need here, it will most certainly bring a smile of gratitude in return.

Would you do that favor?

PhreakNIC 21

Was watching a video presentation on YouTube by Jonathan Ryan at the PhreakNIC 21 annual hacker and technology convention, when near the 26-minute mark during the Q&A session someone posed a question and he whipped out my book, The Art of PCB Reverse Engineering, to answer.

That was some pleasant surprise indeed, considering the event was slightly over a year ago! Now that my sequel book, PCB-RE: Tools & Techniques, was out since the beginning of this year, wonder if he had also purchase it and showcase at the recent PhreakNIC 22 event last month...

Readers interested to watch this video, click here.

Chapter 6

One of the contributors to my trilogy book, PCB-RE: Real-World Examples, has submitted his draft chapter for my vetting and review. I will keep his name and the rest of the contributors in confidence for now. Here is a two-page sample of what you can expect:

PCB-RE involves multi-disciplinary skills and a good deal of engineering experience. Besides the manual method of doing PCB reverse engineering which I'll showcase in my own chapter, there will be other techniques shared by different engineers in their own fields of expertise. Chapter 6 focuses on firmware hacking and you'll learn some very useful lessons as the author takes you step by step through the process, illustrated with many photos and screenshots.

To date, the trilogy has attained 240 pages. I expect it to hit the same number of pages as my other two books when the works of the other contributors come in and take their places.

Black or White

This post has nothing to do with the late Michael Jackson, or even Mike Binder. Rather, it's about a book on doing manual PCB-RE which is in the works, alongside the trilogy book which I'm also working and coordinating with a few contributors.

I've come up with two versions of the cover, one in black and one in white:

Would like to hear from my readers which of these two cover designs is better.

Some readers may ask, "What is the reason for this book? Why work on another when you're already working on the current book?" Inspiration is a funny thing, really. While writing my chapter in the trilogy book, an idea just popped up in my mind to write a bare-bone PCB-RE book for those who simply want the essential know-how of the manual approach, but with enough depth to help them take on real-life projects: a no-frills guide to doing PCB reverse engineering by hand.

In a way, it will supplement my first book, The Art of PCB Reverse Engineering for what it lacks of a complex board example, but which is still full of useful information in documenting the PCB-RE process using Microsoft Visio. However, the book will also be a complete guide in its own right as far as manual PCB-RE is concerned, and with a lower price tag that should appeal to more engineers interested to learn this covert art.

Judging from the progress so far, the trilogy will probably be available sometime in early 2019. But I hope to get this book out by end of 2018 or earlier, depending on how well the contributors to my trilogy are doing.

So keep a look out for more news on these two books...

Analog Zone

Analog ICs are generally simpler compared to their digital counterparts, yet their configurations and connectivity can be more complicated and illusive than we imagine. This is evident as I worked on the Analog Zone of the board, which to date I've covered about two-thirds of the content. Here's a two-page sample:

I'm actually running a little out of steam due to eye and mind fatigue. Writing is definitely hard work compared to hands on which, I suspected, might be the reason why many engineers prefer to work on projects rather than writing reports, or for that matter engineering documentation.

Time for a much needed break!

5-Star Review

It's been quite a while since my sequel book, PCB-RE: Tools & Techniques, received a review, so I was pleasantly surprised to see one, and a comprehensive one, from Sales Manager Mr Daniel Evans of Saelig Company, Inc.

If you're not an engineer, you may think of reverse engineering as a black art by which copycats steal technology or clone a product. Among engineers, the vast majority of reverse engineering is done to facilitate equipment maintenance. 
Regardless of industry, electronics repair shops are often asked to fix circuit boards from equipment that is no longer supported by the manufacturer. Perhaps the support period has expired, or the company is out of business. There may not be any source for a replacement board. The only way to keep the equipment running is to fix the board. In some cases the cost of replacing the equipment may be tens of thousands of dollars, even millions of dollars. So repairing the faulty board can be extremely cost effective, even if the repair costs thousands. 
In cases where a replacement board is available, the cost and/or the lead time to acquire a replacement board may be prohibitive. Repairing the board is a better option. 
Whether the equipment is old or new, a schematic may be helpful or essential for repairing a board. But schematics are often not available, especially for older unsupported boards and even for some newer boards. That's where reverse engineering comes into play. 
PCB-RE Tools & Techniques is a comprehensive resource for anyone or any organization that needs to make schematics for printed circuit boards (PCB). While the author has over 30 years experience in circuit board testing, reverse engineering and repair, the book is much more than one man's experience in reverse engineering. The author has leveraged the reverse engineering expertise of a dozen other engineers from around the world. The result is a compilation of information, techniques, and equipment that will help achieve better, faster solutions to the problems that reverse engineering can present.
Coming from someone with relevant experiences in test and repair equipment, especially the highly popular RevEng system from ABI Electronics, this is a strong endorsement on my book indeed. Thanks and much appreciated, Dan!

Transition Zone

The next step in doing PCB-RE on a mixed-signal board is identifying and tracing the connectivity of the 'transition zone'. This is where 'digital' meets 'analog' in the form of ADCs and DACs:

Readers of my book, PCB-RE: Tools & Techniques, would have been quite well acquainted with the various strategies mentioned in my approach in doing manual PCB-RE. In this trilogy book, readers will be able to see how theory is put into practice, not just by me alone, but by a collective group of other engineers with their own methodologies as well.

Moving on to the next zone...

Digital Zone

Been working on Chapter 3 of my trilogy book, and today I've just finished the 'digital zone' of the real-world PCB example. Here's a two-page sample:

The 'digital zone' covers address, data and control buses, common signals, communication drivers and receivers, jumpers, etc. Next, I'll be covering the 'transition zone'. As to what that is, I'll leave my readers to guess until I'm done with that section.

There's still a lot of grounds to cover so let's get going...

Re-engineering Our Minds

Just received a complimentary copy of the book 'Think to Thrive' from the author Dr. Henry Toi himself, a personal friend of mine:

The subtitle 'Re-engineering your mind for growth' is interesting and insightful, coming from the pen of one who is a thinker as well as an educator. Somehow it struck me that just like reverse engineering PCBs, our minds too need to re-engineer not only to stay relevant and useful, but to attain the next level of excellence.

And that is something for us to THINK about, isn't it?

Interested readers can order a copy at the following online stores:
