THIS GEIGER COUNTER HAS FEW PARTS

With all the focus on biological problems, we might forget that sometimes it’s handy to know about radiation hazards, too. [Ryan Harrington] shows us how to make a Geiger counter with very few parts, and you can see the results in the video below. The glut of surplus Russian tubes has made this a common project, …

Engineers produce smallest 3-D transistor yet

Process that modifies semiconductor material atom by atom could enable higher-performance electronics. Researchers from MIT and the University of Colorado have fabricated a 3-D transistor that’s less than half the size of today’s smallest commercial models. To do so, they developed a novel microfabrication technique that modifies semiconductor material atom by atom. The inspiration behind …

Two bits per transistor: high-density ROM in Intel’s 8087 floating point chip

Ken Shirriff has a detailed write-up about the multi-level ROM in Intel’s 8087 floating point chip: The 8087 chip provided fast floating point arithmetic for the original IBM PC and became part of the x86 architecture used today. One unusual feature of the 8087 is it contained a multi-level ROM (Read-Only Memory) that stored two …

SINGLE ATOM TRANSISTOR WITH ULTRA-LOW POWER CONSUMPTION

Karlsruhe Institute of Technology (KIT) researchers in Germany have developed a single-atom transistor that can reduce the power consumption of electronic systems significantly. The device is being developed by Professor Thomas Schimmel and his team at the Institute of Applied Physics (APH). The single-atom transistor switches electrical current by controlled repositioning of a single atom in a gel electrolyte. The …

Ultra small DC-DC Converter with integrated inductor

The XCL206 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one tiny package (2.5mm×2.0mm, H=1.0mm). A stable power supply with an output current of 600mA is configured using only two capacitors connected externally. Operating voltage range is from 2.0V to 6.0V(XCL20xG:1.8V-6.0V). Output voltage is internally set …

Brand New BiCMOS Flexible Transistor

The transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things since its very first practically implemented device as a point-contact-transistor invented in 1947 and getting the Nobel Prize in Physics in 1956. Now, engineers from the University of Wisconsin-Madison (UW-Madison) have built the most flexible, fully-functional transistor in the world! The BiCMOS (Bipolar Complementary Metal Oxide …

Thermal design: Get the heat out of the electronics

If you have high-powered LEDS, or a power supply, or are trying to control larger motors, you have to get a lot of heat out of your circuit boards. The classic way to dissipate heat is to bolt your power transistor to an aluminum heat sink. That is a slow, messy, and expensive proposition, especially …
