Another analog giant passes... a big loss for the industry and an inspiration to generations of engineers.

Sergio was my professor at SFSU in the 80's. I have fond memories of getting photo copies of a new chapter each week of his Op Amp book that he was writing at the time. I have recently read (but cannot remember exactly where) that you can make almost anything using 555s. We are getting to the days when many of the innovators are gone. Williams, Pease, Jobs and now Camenzind. The real question is where is the next wave of innovators going to come from?

Hans was generous enough to help out with judging the 555contest 2 years ago. It was really great getting to correspond with him and even better getting to see all the fun things people did with the 555 chip.

I believe you are correct. There was a need to innovate in the 555 era. Now it is more packaging and marketing; trading brain cells for eyeballs, and it will get worse. For every exceptional innovation, there are many more tweaks to the innovation, at least in electronics.

Please do not equate Jobs with Camenzid. Jobs was a Marketeer with a great sense of product. He innovated by using the inventions of others in new styling and packaging. Camenzid was an inventor and an engineer. His invention was the core or key component of many other inventions and together brought innovations to the public through myriad companies.

The site is down right now, but if people are interested in seeing some of the amazing things people did with the 555, type "555contest" into YouTube or Google. Lots of amazing entries.

Before microprocessors were readily available, I designed a bazillion machine controllers using the 555 Timer in Sequential Logic. Never had a failure or had it lock up from a power glitch. I had the internal circuitry memorized and used it in ways it was never designed to be used by utilizing the various transistors and functions available through the pins. I still remember the page number in the Sighnetics Data Book it appeared on, page 6-49, and that was 30 years ago. The best, and most useful chip every designed...

Go to his website and download his book on designing analog chips: http://www.designinganalogchips.com/ Maybe you then will be one of our future gurus - like he wanted you to be.
