Sorry, but the X-ray finger detection doesn't pass the sniff test. IR, sure. X-ray, that's just silly.

I have to admit, once you've used the original built-like-tanks HP test equipment, nothing else seems to measure up. But hey, leaving that aside, I'm intrigued by your bio. I'm curious about accents. To my admittedly not hyper-trained ear, English spoken in Zimbabwe/Rhodesia and South Africa especially, sounds quite similar. And not too different from English spoken in Australia and New Zealand. So here's my question. If I may ask, when you moved to Oz, did everyone notice your accent and ask about it, or not? (Or perhaps you fooled them all, and me, by sounding like a yank?)

I enjoyed many years working as a design engineer at HP. One of best projects was working on a new full-custom CMOS chipset at the calculator division in Corvallis, Oregon. We could do it all in those days because the standard-cell approach wasn't around yet or suitable. We created our schematics and simulated them with HP Spice and proprietary logic simulators. We could walk over to the CMOS process engineer's desk and discuss spice parameters nuances, or discuss bus contention detection with the guy that wrote the logic simulator. We could even do our own CMOS layout and netlist extraction and verification. We could wear a "bunny suit" and enter the CMOS fab to watch our wafers be processed, and manually probe them at a probe station to verify internal circuit operation. HP created as many as 7 full-custom ASICs for a new architecture in those days and the teamwork was amazing. I learned so much from the high caliber people I worked shoulder-to-shoulder with. I also witnessed some of the most amazing assembly language code reviews. In those days of 1MHz CPU clocks and 4KB SRAM chips every cycle and byte mattered. During a code review you could hear one engineer tell another: "if you move instruction XXX before instruction YYY you can eliminate instruction ZZZ saving two bytes and three clocks"! We also frequently heard from customers whose calculators had survived amazing destruction, including one from a bombing in Ireland. It was grand engineering on this scale that is the legacy for things like the HP-35, HP-41 and HP-48. I am sure hundreds of lucky engineers like me participated in a similarly fulfilling engineering environment at other HP Divisions around the country. It was truly the best of days!

I was hired by HP as a Production Engineer in 1965 in Loveland CO. One of the products I was responsible for was the 200CD. In those days it wass literally raw material to finished product. It seems to me that we made everything in Loveland except the basic electronic components.

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
