Sometimes you need to display a number nice and large, making it easily readable at a good distance. [Lewis] has just the thing for that: a big expandable 7-segment display. The build is modular, allowing it to be extended from 2 to 10 digits and beyond. The digits themselves are made of 3D-printed parts assembled onto […]

There have been plenty of Z80 computer builds here on Hackaday, but what sets them apart is what you do with them. [Andrew] writes in with his Z80 single-board computer made from scratch, using the Arduino standard headers for its I/O. In turn, since he needed an easy way to program the flash memory which holds
Z80 COMPUTER IS BOTH ARDUINO AND SHIELD Continue Reading
Efficient as fiber optic cables are at transmitting data in the form of light pulses, they do need to be physically supported, and they can only handle a finite amount of power. Still, what’s the alternative … just send those focused pulses through the air? Actually, that’s just what scientists at the University of Maryland
“Air waveguides” used to send optical data through the air Continue Reading
Vishay Intertechnology, Inc. has introduced two new families of 2A to 12A microBUCK® synchronous buck regulators featuring wide input voltage ranges from 4.5V to 55V (SiC476/7/8/9) and 4.5V to 60V (SiC466/7/8/9). Combining rugged high-performance n-channel trench MOSFETs with a controller in the compact 5×5 PowerPAK® package, the Vishay Siliconix devices deliver high efficiency and power

Microchip announces a new family of Serial Peripheral Interface (SPI) EERAM memory products, branded as “EERAM Memory Solutions,” that offers system designers up to 25 percent cost savings over the current serial Non-Volatile RAM (NVRAM) alternatives. The family introduces four reliable SPI densities to Microchip’s EERAM portfolio, ranging from 64 Kb up to 1 Mb
EERAM MEMORY SOLUTIONS REDUCE MEMORY COSTS AND RETAIN DATA AT POWER LOSS Continue Reading
Digital displays are useful for quick and accurate readout, but lots of people prefer the physical motion of a needle moving along a dial. For instance, many smartwatch users choose an analog face to show the time, and modern cars with digital dashboards often default to showing an analog speedometer. Following this trend, [Miro Pavleski]

A small team of researchers led by Peter Baltus, professor of microelectronics at the department of Electrical Engineering at Eindhoven Institute of Technology, the Netherlands, has developed small circuit boards equipped with sensors that can easily fit into a small golf-sized ball. While moving inside a pipeline, these swarm of smart marbles or balls can detect any obstacles, damages

Theremin is one of the most exiting musical instruments ever made, mainly because of its “quite odd” playing method. Infact, its working principle is based on near-filed coupling between the hands of the theremin player and two metal antennas, used to determine the pitch of a variable-frequency oscillator and to adjust the volume of the output signal, respectively. Several theremin
