I had earlier built Original Hiland DIY M12864 Graphics Version LCR ESR PWM Transistor Tester Kit and used it successfully. The kit worked well, but on longer term use I felt that the lack of proper case for it was sometimes annoying. I had some time though if making my own case, but it felt →
I had one Elisa viihde base WLAN station + ADSL modem that was unreliable. I had earlier done tear-down of it that I posted to this blog. Now it is time to try to fix it, because it was making whining noise and was a bit unreliable as WLAN base station. So it looks like →
https://techcrunch.com/2018/04/16/microsoft-built-its-own-custom-linux-kernel-for-its-new-iot-service/ Microsoft announced the launch of a secure end-to-end IoT product that focuses on microcontroller-based devices. At the core of Azure Sphere is a new class of certified MCUs. MediaTek is producing the first set of these new MCUs (single-core ARM-A7 systems that run at 500MHz). Interesring twist is that for the first time ever, →
I have earlier tested basic DIY Electronics Tester Kit M168 and more advanced Component tester M12864. Now it is time to test the next improved version of the same idea: Original Hiland DIY M12864 Graphics Version LCR ESR PWM Transistor Tester Kit (was on sale for less than 10 Euros) This kit has same display →
Here are some of my collection of newest trends and predictions for year 2018. I have not invented those ideas what will happen next year completely myself. I have gone through many articles that have given predictions for year 2018. Then I have picked and mixed here the best part from those articles (sources listed →
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 →
Rane Sound System Interconnection note, originally written in 1985, continues to be a very useful reference. It’s popularity stems from the continual and perpetual difficulty of hooking up audio equipment without suffering through all sorts of bizarre noises, hums, buzzes, whistles, etc.– not to mention the extreme financial, physical and psychological price. Many things have improved →
I have earlier written on using DMX-512 controlled dimmer to control mains powered lamps. It works, but is expensive and traditional incandescent lamps are going out of fashion. LEDs are the future, so a cheap easy to use board for controlling low voltage LEDs with DMX-512 signal are needed. To experiment with LED conrolling I →
According to Intel IoT is expected to be a multi-trillion-dollar market, with 50 billion devices creating 44 zettabytes (or 44 trillion gigabytes) of data annually by 2020. But that widely cited 50 billion IoT devices in 2020 number is clearly not correct! Forecast of 50 Billion Devices by 2020 Is Outdated. In 2017 we should →
The RSA SecurID authentication mechanism consists of a “token” — either hardware (e.g. a USB dongle) or software (a soft token) — which is assigned to a computer user and which generates an authentication code at fixed intervals (usually 60 seconds) using a built-in clock and the card’s factory-encoded random key (known as the “seed”). →
