TURBO BUTTON PAYS CHARMING HOMAGE TO EARLY PERSONAL COMPUTERS

TURBO BUTTON PAYS CHARMING HOMAGE TO EARLY PERSONAL COMPUTERS

Leave a Comment / Arduino News / By

The PC turbo button and LED clock speed display were common features on early personal computers. Wanting to add a little retro chic to his modern battle-station, [Matthew Frost] assembled a charming and functional homage to the turbo button control panel. In days past, this automotive nomenclature implied a performance boost when activated. Instead, ‘turbo mode’ …

Fire Prediction using Arduino nano BLE sense and Machine Learning

Leave a Comment / Sensor – Transducer – Detector Projects / By

An Embedded Machine learning-based project was used to detect fire using the inbuilt colour sensor. Description It’s an embedded machine learning-based project used to predict a fire in Arduino nano ble 33 sense with the help of the inbuilt color sensor attached to the board and if the fire has been detected a buzzer is …

MEET THE NEXT-GEN LITHIUM-SULFUR BATTERIES

Leave a Comment / Electronics News Updates / By

What would you give for a battery, 5x the storage capacity of whatever you’re reading from? Well, the countdown to commercial availability for batteries of this type of capacity has already begun and it would be considerably cheaper than then currently available batteries. This radical improvement comes from using sulfur cathodes rather than graphite in lithium-ion batteries. Sulfur …

NETWORK CLOCK USING ESP8266 AND OLED DISPLAY

Leave a Comment / Electronics News Updates / By

There are several situations where using an RTC could adversely affect your project by increasing cost, size, time accuracy or IO requirements. To prevent this, especially in ESP/WiFi-based or other clock-reliant projects, makers usually turn to obtain time information from NTP servers. I recently came across a project by BitsandBlobs which used standalone NTP Servers and I felt …

NEW GAP9 IOT OFFERS FIVE TIMES LOWER POWER CONSUMPTION THAN GAP8

NEW GAP9 IOT OFFERS FIVE TIMES LOWER POWER CONSUMPTION THAN GAP8

Leave a Comment / Electronics News Updates / By

Last year, GreenWaves Technologies launched the GAP8 multi-core RISC-V microcontroller, aimed at artificial intelligence (AI) at the edge at ultra-low power consumption. Results from the GAP8 IoT SoC shows it performs inference at 3.7mA against 60mA for the same workload on STM32F7 Arm Cortex-M7 MCU. As a result of this performance, the company has now expanded its GAP IoT application processor family They launched GAP9, which …

FREE ELEKTOR ARTICLE: A 3-DOLLAR TINY WI-FI SWITCH THAT WORKS

Leave a Comment / Electronics News Updates / By

Out of curiosity I ordered a tiny ESP8266 relay switch board from aliexpress.com, for next to nothing. Blissfully unaware, then, of the struggle ahead to make the thing work as advertised. I survived and conquered — here’s the story. By Somnath Bera The little gizmo pictured in Figure1 was stated by the vendor(s) to contain an inbuilt …
