On December 11th, the FCC announced that the band around 6GHz would be open to “very low-power devices.” The new allocation shares space with other devices already using these frequencies. …read more Continue reading The 6GHz Band Opens in the US
[Happy Little Diodes] built a Pi Pico logic analyzer designed by [El Dr. Gusman] using the original design. But he recently had a chance to test the newest version of …read more Continue reading Pico Logic Analyzer Gets New Version
Have you ever considered running your ham radio remotely? It has been feasible for years but not always easy. Recently, I realized that most of the pieces you need to …read more Continue reading It’s Remotely Ham Radio
Typically, if you want to build an FPGA project inside a PC, you’d need a fairly expensive development board that plugs into the bus. However, [CircuitValley] found some IBM RS-485 …read more Continue reading Cheap FPGA PCIe Development
Playing chess has always been a bellwether for computers. The game isn’t trivial, but the rules are managably simple. However, the game is too complex to be easily solved entirely, …read more Continue reading Microchess Remembered
If you want to analyze an antenna, you can use simulation software or you can build an antenna and make measurements. [All Electroncs Channel] does both and show you how …read more Continue reading Antenna Measurement in Theory and Practice
Oscillators may use crystals as precise tuned circuits. If you have a vector network analyzer (VNA) — or even some basic test equipment — you can use it to learn …read more Continue reading VNAs and Crystals
We will admit it. If we found a 386 motherboard as badly corroded as the one [Bits und Bolts] did, we would trash it—not him, though. In fact, we were …read more Continue reading How Corroded Can a Motherboard Be?
OK, I know. We don’t have practical teleportation. But that hasn’t stopped generations of science fiction authors and movie makers from building stories around it. If you ask most ordinary …read more Continue reading A Brief History of Teleportation
There was a time when ham radio operators were known for having long conversations over the radio — rag chewing, as they called it. A new program, LongChat, is a …read more Continue reading LongChat for Ham Radio
