Conventional speakers work by moving air around to create sound, but tiny speakers that use ultrasonic frequencies to create pressure and generate sound opens some new doors, especially in terms …read more Continue reading Tiny Speaker Busts Past Sound Limits with Ultrasound
The consumer electronics space is always in a state of flux, but perhaps nowhere is this more evident than with entertainment equipment. In the span of just a few decades …read more Continue reading Teardown: Sling Adapter
Selling to developers is different from the standard B2B playbook, but it isn’t impossible. There’s a considerable amount of opportunity to create real value for this persona. Continue reading SaaS companies can grow to $20M+ ARR by selling exclusively to developers

The Kr00k bug arises from an all-zero encryption key in Wi-Fi chips that reveals communications from devices from Amazon, Apple, Google, Samsung and others. Continue reading Billions of Devices Open to Wi-Fi Eavesdropping Attacks
Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, position-sensitive input, like you’d find on a computer touchpad or your smartphone screen? Not so easy — at least until now. Trill …read more

Infineon will acquire Cypress Semiconductors for nearly $10 Billion dollars. This is the latest merger or acquisition in the semiconductor industry, and these mergers and acquisitions show no sign of stopping anytime soon.
Infineon’s market currently consists mostly of products aimed at the automotive market and power management and control. …read more
You may think electrochemistry sounds like an esoteric field where lab-coated scientists labor away over sophisticated instruments and publish papers that only other electrochemists could love. And you’d be right, but only partially, because electrochemistry touches almost everything in modern life. For proof of that look no further than your nearest pocket, assuming that’s where you keep your smartphone and the electrochemical cell that powers it.
Electrochemistry is the study of the electrical properties of chemical reactions and does indeed need sophisticated instrumentation. That doesn’t mean the instruments have to break the grant budget, though, as [Kyle Lopin] shows with …read more

[Larry Wall], the father of Perl, lists the three great virtues of all programmers: Laziness, Impatience, and Hubris. After seeing that Saleae jacked up the prices on their popular logic analyzers to ludicrous levels, [CNLohr] added a fourth virtue: Spite. And since his tests with a Cypress FX3 over the last few days may lead to a dirt-cheap DIY logic analyzer, we may soon be able to add another virtue: Thrift.
The story begins a year or two ago when [CNLohr] got a Cypress FX3 development board for $45. The board sat unused for want of a Windows machine, but …read more

Careful not to sneeze while using this diminutive logic analyzer — you could send it flying across the bench.
Undertaken more for the challenge than as a practical bench tool, [Uwe Hermann]’s tiny logic analyzer is an object lesson on getting a usable circuit as small as possible. Sure, some sacrifices had to be made; it’s only an eight-channel instrument without any kind of input protection at all, and lacks niceties like an EEPROM. But that allows it to fit on a mere 11 x 11-mm fleck of PCB. That’s a pretty impressive feat of miniaturization, given that the Cypress …read more
