To My Readers



If this is the first time you're visiting my blog, thank you. Whether you're interested or just curious to find out about PCB reverse engineering (PCB-RE), I hope you'll find something useful here.

This blog contains many snippets of the content in my books to provide a more detailed overall sampling for my would-be readers to be better informed before making the purchase. Of course, the book contains more photos and nice illustrations, as evidence from its cover page. Hopefully, this online trailer version will whet your appetite enough to want to get a copy for yourself.

Top Review

I started doing component level repair of electronics with (and without) schematics more than 40 years ago, which activity often involves reverse-engineering of printed circuit boards. Although over the years my technical interests have shifted into particle beam instrumentation, electron microscopy, and focused ion beam technology fields, till this day——and more often than not——PCB repairs have returned multiple multi-million-dollar accelerators, FIB, and SEM instruments back to operation, delivering great satisfaction and some profit.

Many of the methods described by Keng Tiong in great details are similar to the approaches I've developed, but some of the techniques are different, and as effective and useful as efficient and practical. Systematic approach and collection of useful information presented in his books are not only invaluable for a novice approaching PCB-level reverse engineering, but also very interesting reading and hands-on reference for professionals.

Focus on reverse engineering instead of original design provides unique perspective into workings of electronics, and in my opinion books by Keng Tiong (I've got all three of them) are must-read for anybody trying to develop good understanding of electronics——together with writings by Paul Horowitz and Winfield Hill, Phil Hobbs, Jim Williams, Bob Pease, Howard Johnson and Martin Graham, Sam Goldwasser, and other world's top electronics experts.

Reset, ReSET, RESET...!!!

I'm not much of a fan of the World Economic Forum, an international non-governmental and lobbying organization that meddles with the economic affairs of the world. Since the start of the CoVid-19 pandemic it's founder, Klaus Schwab, has been entertaining the possibility of a Global Reset, a move that he believes will help bridge the gap between the rich and the poor. But not many people buy into his idea, especially his wry remark:

Seriously, we'll own nothing and be happy? 50 years on since founding the WEF (or as some people say, WTF), he may be close to realizing his dream of owning a large part of the world with the rest of the global elites, while the rest of us are expected to loan the earth from 'them', our masters. This is one BIG RESET I would rather not see happen.

The only kind of reset that is of real benefit is the PoR i.e. 'Power on Reset'. Most electronics and computer systems depend on it to function properly and predictably, though getting the charge-up time correctly is a matter of trial and error.

Now, if only there's a Re-SET that can redistribute the wealth of these greedy globalists to the needy and hardworking people of the world, that would be nice, isn't it? We just need to find THAT switch to the MARTIX...
