Overclocked Intel CPU draws 1kW
https://www.electronics-lab.com/overclocked-intel-cpu-draws-1kw/
by Thomas Scherer @ elektormagazine.com The impressively powerful i9-7980XE CPU from Intel boasts not just 18 cores and 36 threads but also an unlocked clock multiplier. The spec was clearly an open invitation to Roman Hartung who has something of a reputation when it comes to overclocking processors. In tests he was able to crank […]
DSETA board with an AT89C51ED2
https://www.electronics-lab.com/dseta-board-at89c51ed2/
Jesus Echavarria tipped us with his latest DSETA board with an AT89C51ED2. Some months ago I review the DSETA board due the obsolescence of the microcontroller. I use this board in some projects succesfully. But when I try to manufacture a batch of this boards, I found that the microcontroller (AT89C51RE2) was obsolete. So, the […]

Alzheimer’s Wearable Assistant
https://www.electronics-lab.com/alzheimers-wearable-assistant/
A smartwatch with fall and location detection, reminders and more, designed to help you or your loved one with Alzheimer’s! When I saw Infineon’s Sensor Hub Nano, it appeared to be a good candidate in such a project, because of its very small size and BLE capabilities. With the accurate pressure sensing, it could be […]
Nutube – low power vaccum tube
https://www.electronics-lab.com/nutube-low-power-vaccum-tube/
A new vacuum tube which puts vacuum fluorescent display technology to practical use is in distribution from RS Components. Nutube, similar to a conventional vacuum tube, has an anode grid filament structure, and operates exactly as a triode vacuum tube. Also similar to a vacuum tube, it creates the same characteristic rich overtones. By applying […]
Researchers Innovated Highly Effective Silicon Microchannel Thermal coolers For Processors
https://www.electronics-lab.com/researchers-innovated-highly-effective-silicon-microchannel-thermal-coolers-processors/
One of the limiting factors for the computing power of processors is the operating temperature. A research team led by Dr. Wolfram Steller, Dr. Hermann Oppermann, and Dr. Jessika Kleff from the Fraunhofer Institute for Reliability and Microintegration IZM, has developed a new as well as an efficient cooling method by integrating microchannels into the silicon […]
