I grew up hacking on 555 circuits, and I design them into commercial products today. Hans Camenzind, you changed the world for the better. Thank you. Rest in peace.

As so many people, since a very long time, I (we) used that 555. A great brain we will miss. Rest in peace.

A VP at a company I was working at 15 years ago insisted on me using a computer to run a piece of production machinery. Because this type of machine has a lifetime exceeding 30 years, I argued against it because of reliability concerns. I was overruled. The computer-controlled machine has had to have numerous computer upgrades over the years to keep up with industry-wide hardware and software changes at great cost in downtime and reliability. The machines run on 555 Timers are still running 30 years later without a failure and are still in production. The computer controlled machine now needs to be completely redone at enormous cost because the hardware is too outdated to upgrade any longer. The moral is, just because we can go "digital" doesn't mean we should.

I'm putting into production soon a simple design that uses the 556 device. It really is amazing what the "old school" technology can still do for little money.

Without the work of what people Camenzind did, Steve Jobs couldn't have done anything. Different people with differentskills, but someonehas to invent the basic technology first. Where would we be without folks who cando that?

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.

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...

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.

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.

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.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
