500 Terawatt Shot Smashes Laser Record

The Lawrence Livermore National Laboratory's National Ignition Facility laser system of 192 beams produced more than 500 terawatts of power and 1.85 megajoules of ultraviolet laser light to its target. This is 1,000 times more power than the entire United States uses at any instant in time!

Find out why researchers hope this new laser record will change the world, plus the latest robotic and biomedical inventions!
Servo Motor

How It Works: Servo Motors

Chances are you've used servo motors in your electronics projects before. They can be used to help robots walk or to drive remote-controlled trains, planes and automobiles. But do you have any idea how those powerful and efficient little puppies work?

Street View

How'd They Do That?

Google Street View

Marc Weber, Founding Curator, at the Computer History Museum in Mountain View, CA takes an in-depth look at mapping technology and its origins. A project originally inspired by top-secret army rescue mission training, Google street view is a technology we all take for granted.

Learn how the technology we take for granted came to be and how it's captured.

Club Jameco Project: DIY Audio Easter Egg

Audio Easter Egg Club Jameco member David Allen Thom has designed a kit that is fun for all ages. It creates a chirp that sounds like a chick from inside the Easter egg. You can create a harmonized choir or a variety of egg tones that is likely to entice any hunter. The kit's circuit is based on multiple oscillators built from a single 74HC05 Hex inverter that emits chirping sounds based on differing resistor values. And it is all designed to fit into a plastic egg!

Create your own chirpy egg basket chorus.

Club Jameco projects are created by hobbyists like you. Anyone can design a project and earn a commission every time the kit sells. Find hundreds of electronics projects and learn more at www.ClubJameco.com

My Story: LED Propeller Clock

Propeller Clock Long-time Jameco customer and retired electronics teacher Bob Blick says that this is one of his coolest projects. The spinning LEDs not only keep super accurate time, but rely on the Persistence of Vision (POV) phenomenon, so the electronic clock's numbers appear to be floating in air.

Build your own POV clock with these step-by-step instructions.

Greg's Corner: The End of Time

Greg Corner It was a warm sunny Tuesday in July. I stepped out for a bite to eat. When I returned I was stunned to see that 300 new emails came in while I was at lunch and that number would grow to over 700 before the day ended. While others routinely ignore customer emails or delegate the responsibility, I've bragged for more than a decade that I answer every customer personally the same day. But how could I possibly meet that commitment?

Read about my emotional roller coaster as I tried to live up to my commitment to myself.

Yes, I really respond to every customer and generally that happens within four business hours. I find that the value of the information I get is worth much more than the cost in time that it takes to respond. Write me some time and tell me how we can do our job better.

Regards,
