I have had for a long time an AKG D60 S microphone. The AKG D60S is advertised as an unidirectional semiprofessional dynamic microphone with smooth frequency response, a rugged all-metal body, an on/off switch, and removable wire-mesh grill. It was proven to be a decent semiprofessional all-round microphone with hypercardioid polar pattern. Hypercardioid microphones are →
It’s cool to see a functional tool like the oscilloscope manipulated to display unrelated art. When you input suitable stereo audio into an old scope in in X-Y mode, you can see all kinds of artistic creations. Salvaged Scope Lets You Watch the Music article introduces you how to use old scope for video art. →
We were promised Intenet of Things interoperability on sales pitch, but we seem to end up is living with landfill full of proprietary shot-lived wallet gardens of crappy things. “But that Google can suddenly decide to sunset a cloud API that hundreds of IoT devices have been talking to for less than five years is →
While switching to LED lighting certainly helps reduce power consumption, we can do more. Each conventional mains powered LED bulb has its own AC/DC power supply, which is needed for bulbs to be compatible with AC wiring and lighting fixtures with sockets designed 100 years ago. Having individual power supplies adds cost and decreases efficiency →
This posting is here to collect cyber security news in September 2019. I post links to security vulnerability news to comments of this article. If you are interested in cyber security trends, read my Cyber security trends 2019 posting. You are also free to post related links. →
Zach Shelby from ARM tells in this article that we can already run meaningful machine learning inference on Cortex-M equivalent microcontroller hardware. How we can utilize that in our future hacks? https://blog.hackster.io/embedded-ml-for-all-developers-1f000ccdaddd I saw Zach Shelby few months ago telling how to do that in conference, tried one demo myself and talked him in person. →

The world’s best new library for 2019 located on Helsinki Finland has robots in it. The robots were used to move books and showing customers where the fiction section →
There has been for several years talking that nanotube transistors are coming to use and they can be better than traditional transistors made of silicon. I see this news as a major milestone. IEEE Spectrum writes: https://spectrum.ieee.org/nanoclast/semiconductors/processors/modern-microprocessor-built-using-carbon-nanotubes Engineers at MIT and Analog Devices have created the first fully-programmable 16-bit carbon nanotube microprocessor RV16X-NANO. It’s the →
This is a teardown of an Omron M6 Comfort blood pressure monitor. This was several years old model (newer looks different). This teardown was done because this was no longer reliable – the display was missing most of graphics. Let’s open it. Open two screws and use pry tool to open plastic case. Let’s go →
