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 […]

This is one small project which I had done with Abhinav Gupta some months back. In this experiment, I graduate from using simple RF communication to Xbee! Whoa! Ok, so here is the basic problem statement. I need to develop a temperature sensing system such that the temperature from the sensor node is relayed to

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
NEW GAP9 IOT OFFERS FIVE TIMES LOWER POWER CONSUMPTION THAN GAP8 Continue Reading
A small team of researchers led by Peter Baltus, professor of microelectronics at the department of Electrical Engineering at Eindhoven Institute of Technology, the Netherlands, has developed small circuit boards equipped with sensors that can easily fit into a small golf-sized ball. While moving inside a pipeline, these swarm of smart marbles or balls can detect any obstacles, damages

Arduino enthusiast Roni Bandini has created an interesting project investigating is it possible to train a small device with artificial intelligence in order to detect harmful gases? In this machine learning project an Arduino microcontroller was used together with a multi gas sensor and Edge Impulse are used to achieve the goal. Detects harmful gases “Experiencing a chemical

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

Network monitoring is very important in todays world. The internet is a scary place. People have taken steps to raise their awareness by installing Intrusion Detection Systems(IDS) such as SNORT. The problem with most of these systems is that upon first installing them they are vigilantly watched. After a week the allure wears off and
