No Pots? No Problem!

Forrest Jameco Puzzler By Forrest M. Mims

The year is 2021 and the Federal Panel of Obsolete Technology (POT) has banned the manufacture, sale and use of manually adjustable (analog) potentiometers, trimmers and the like. Only digitally-programmable potentiometer technology can be manufactured and used. Consultant Leo Smith is an analog old timer with a thriving business designing work-arounds for circuits that would work much better if "old-fashioned" analog components banned by the POT were still available. How did Leo design a rotary-style, continuous (no steps) volume control for a children's portable radio without breaking the law?

Football Line

How It Works: Football's Magical Yellow Line

By Robert Cong

Football is back in action. Beyond the rivalries, the fanatics and the tailgating, there's some pretty amazing technology. We count on that yellow line to tell us where the first down is, and in fact, it's hard to imagine how people ever watched football without it. How's it done and what's the technology that paints the yellow line on our screens? It's not nearly as simple as it looks. We explain the technology and hopefully will heighten your appreciation at the same time.

How the heck do they get that yellow line in there?

Listen and Learn

By Greg Harris

Listen and Learn Last month's newsletter hadn't been out more than an hour when a reader replied, "I just wanted to let you know that I'm going to get a haircut before going home. Is that ok?" I quickly replied and told him that "Jameco is pro-haircut" and it was fine with us.

Not long after, I had to place an order with a company that was supposedly an expert in e-commerce. The system frustrated me and I wasn't able to place my order. I call to ask for help but everyone that could help was apparently on vacation, so I asked for the president’s voicemail. The person on the other end of the phone actually laughed at me... at which point I lost it.

What's amazing is what happened next... read more.
