via HACKADAY: Scribble Your Way To Quick Printed Circuit Boards

There are a variety of techniques employed by electronic constructors seeking the convenience of a printed circuit board without the inconvenience of making a printed circuit board. Dead bug style construction in which the components float on a spiders-web of soldered leads above a ground plane is one, Manhattan style construction in which pads made […]

The Great American Eclipse: Virginia Tech researcher grapples with a year’s worth of data

Stationed in an empty field at Shaw Air Force Base near Sumter, South Carolina, Virginia Tech electrical engineering professor Greg Earle and his team waited for the total solar eclipse of 2017. Rather than traveling toward the path of totality to see one of “nature’s most awe-inspiring sights,” Earle prepared to put his three-year-old hypothesis […]

via HACKADAY: The components are INSIDE the circuit board

Through-hole assembly means bending leads on components and putting the leads through holes in the circuit board, then soldering them in place, and trimming the wires. That took up too much space and assembly time and labor, so the next step was surface mount, in which components are placed on top of the circuit board […]

via HACKADAY: Attack Some Wireless Devices With A Raspberry Pi And An RTL-SDR

If you own one of the ubiquitous RTL-SDR software defined radio receivers derived from a USB digital TV receiver, one of the first things you may have done with it was to snoop on wide frequency bands using the waterfall view present in most SDR software. Since the VHF and UHF bands the RTL covers […]
