Low Cost Magnetic Loop Antenna For 10-12 Meters

“I decided to build a magnetic loop antenna that would cover the ham radio frequencies from around 20 to 30 Mhz so I could use it on portablewith my Magnum 1012 hand held radio. This is what I come up with. Since those bands are heating up now with the progress of the new sun spot cycle, this should be fun to use with the low power output of the radio and should make a better antenna than the duck...

High school students call around the world via amateur radio club

Gabrielle Calise/The Gainesville Sun Bryan Clark, a 15-year-old Loften High School student and vice president of the ham radio club, attempts to make contact with other radio operators. The high schoolers stand in a cluster around a desk in the classroom, listening to the crunching waves of static as the operator turns a dial on the radio, searching for a clear signal. “If they sound like Donald Duck, then you’re a little off frequency,” said club adviser Bob Lightner. Students at the Professional...

Project Jacquard – Weave touch and gesture interactivity into any textile

Project Jacquard makes it possible to weave touch and gesture interactivity into any textile using standard, industrial looms. This is possible thanks to new conductive yarns, created in collaboration with our industrial partners. Jacquard yarn structures combine thin, metallic alloys with natural and synthetic yarns like cotton, polyester, or silk, making the yarn strong enough to be woven on any industrial loom. They are indistinguishable from the traditional yarns that are used to produce fabrics today. The complementary components are engineered...

Why Modern Makers Are Bringing Back Ham Radio

More than a hundred years ago, a few intrepid amateurs began experimenting with a new means of communications known then as “wireless.” These protohackers — soon to be known as hams — foretymologically obscure reasons — began building their own electronics gear, hoping to use it to communicate with others. By the early 1920s, amateur radio operators were talking with and even transmitting images to complete strangers on the other side of the world. By the 1980s, ham radio was in...
