Why Hardware Is Hard, But Easier Than Ever – Hackster’s Blog

https://blog.hackster.io/why-hardware-is-hard-but-easier-than-ever-eeca5d464726 Hardware is hard is so commonly said it has become a cliché. Yeah, you know it’s hard, but why exactly? This article discusses this in detail. Fortunately, there is good news too — developing and launching a new hardware product is easier now than it’s ever been.  Making hardware is hard because developing a hardware product encompasses multiple fields

Chip Hall of Fame: Texas Instruments Digital Micromirror Device – IEEE Spectrum

https://spectrum.ieee.org/semiconductors/optoelectronics/chip-hall-of-fame-texas-instruments-digital-micromirror-device Today movie projectors based on this digital light-processing technology—or DLP, as TI branded it—are used in thousands of theaters. It’s also integral to rear-projection TVs, office projectors, and tiny projectors for cellphones.

Chip Hall of Fame: Acorn Computers ARM1 Processor – IEEE Spectrum

https://spectrum.ieee.org/semiconductors/processors/chip-hall-of-fame-acorn-computers-arm1-processor Unsatified with the processors then available on the market, the Acorn engineers decided to make the leap to creating their own 32-bit microprocessor. ARM1 was released in 1985. They called it the Acorn RISC Machine, or ARM. In 1990, Acorn spun off its ARM division, and the ARM architecture went on to become the dominant

Chip Hall of Fame: Intersil ICL8038 Waveform Generator – IEEE Spectrum

https://spectrum.ieee.org/semiconductors/devices/chip-hall-of-fame-intersil-icl8038-waveform-generator Intersil’s ICL8038 integrated circuit was designed to meet the need for a convenient way to obtain a precise waveform, capable of simultaneously generating sine, square, and sawtooth waveforms with only a few supporting external components. After some time 8038 became a major hit. I remember that IC because I used it for my first function generator I

Shields are your friend, except when… | EDN

So what could go wrong? Well 10 years ago, not

How to pre-test your product’s antenna | EDN

Most hardware and software is thoughtfully tested before sale or deployment, but why are so many antennas ignored? There is no reason to defer or ignore your antenna evaluation; help is available.

Banana connector types

https://en.m.wikipedia.org/wiki/Banana_connector A banana connector is a single-wire (one conductor) electrical connector used for joining wires to equipment. The term 4 mm connector is also used, especially in Europe,because the pin’s diameter is nominally 4 millimetres (0.16 in).The pin has one or more lengthwise springs that bulge outwards slightly, giving the appearance of a banana. The original plug consists of a cylindrical metal pin about 20 millimetres (0.79 in) long.However other

Small switch mode PSU module MPS MP2307 fail

I  need power supplies for different eletronics circuits. I decided to get some cheap switch mode power supply modules 5Pcs Mini DC Adjustable Power Supply Buck Module Step Down Module (available also as single unit). The ideas was to try to use them instead of power wasting traditional linear regulators. 5Pcs Mini DC Adjustable Power

Bespoke Processors: Cheap, Low-Power Chips That Only Do What’s Needed – IEEE Spectrum

http://spectrum.ieee.org/tech-talk/semiconductors/design/bespoke-processors-cheap-lowpower-chips-that-only-do-whats-needed This article tells about interesting approach to processor design: Starting with a Texas Instruments openMSP430, they produced bespoke designs. “Our approach was to figure out all the hardware that an application is guaranteed not to use irrespective of the input,” says Kumar. What’s left is “a union, or superset, of all possible paths that data
