From a tiny sample of tissue no larger than a grain of sand, scientists have come within reach of a goal once thought ...

A simple AM transistor radio can be made with surprisingly few components, but for a circuit with a reasonable performance they suggest six transistors to be the optimal number. If we think about ...

A step forward in the development of diamond CMOS integrated circuits. A research team at NIMS has developed the world’s ...

Wayne recommends double-walled heat-shrink tubing. This type of heat shrink includes an inner lining of hot melt glue with ...

“If you have a broken radio and you have the circuit diagram, you’ll be in a better position to fix it,” said Nuno da Costa, Ph.D., associate investigator at the Allen Institute. “We are describing a ...

Each PCB is housed within a Radio Frequency Current-Voltage (RFIV ... are for attaching additional antennas to form the tomography array. Figure 4. RFIV circuit board diagram. The input signal at ...

"We don't know the frequency, so we need to keep tuning and trying different ones, like searching for a good radio station ...

One of the great things about our growing number of local low-powered community FM stations is the ability to find programming you can’t find elsewhere.

My first battery-powered radio — a ten-transistor Realtone — came from my Aunt Ina when I was about seven. I used to think I was ten, but the songs from 1973 would be wrong: I distinctly ...
