Raj @ embedded-lab.com published a revised version of an old project, a programmable Relay Switch based on PIC16F1847 (or PIC16F628A) that can be used is various automation applications and you can independently set ON and OFF timer with maximum time interval 99 hours and 59 minutes. Here are the summary of the features that this programmable relay switch […]
Tiny motion sensor fits wearable devices
https://www.electronics-lab.com/tiny-motion-sensor-fits-wearable-devices/
by Susan Nordyk @ edn.com: Bosch Sensortec’s BMX160 is a 9-axis motion sensor touted as the smallest in the industry for wearable and augmented/virtual-reality devices. The miniature device is housed in a 2.5×3.0×0.95-mm, 14-pin LGA package, small enough for smartphones, smart watches, fitness trackers, and even smart eyewear and jewelry. Combining an accelerometer, gyroscope, and geomagnetic […]

Creating your first IoT Ethernet Device – IoT, Home Automation
https://www.electronics-lab.com/creating-first-iot-ethernet-device/
In this series of tutorials SteveQuinn show us how easy is to build a IoT Ethernet Device using ESP8266-01 WiFi module and how interface BMP085 barometric sensor, DS1307Z RTC, ILI9431 and log the data on a SD card. As mentioned, this Instructable is split into two parts. Part (A) documents how relatively simple it is […]
Hacking the OWON SDS7102 Scope
https://www.electronics-lab.com/hacking-owon-sds7102-scope/
Christer Weinigel did a teardown of OWON SDS7102 oscilloscope. He explained how its internals are connected, ported Linux to its Samsung SoC in the scope, succeeded in getting its peripherals working, and set to work programming the Xilinx FPGA that’s responsible for signal processing. One of the reasons I bought this specific scope was that I […]
AVR vs PIC: The case of the candle
https://www.electronics-lab.com/avr-vs-pic-case-candle/
A self-igniting candle implemented using AVR and PIC microcontrollers. This project has two variations, one using an ATTiny25, the other using a PIC12LF1822. In a series of minimalistic devices, this electronic candle periodically measures ambient light levels. Once it detects nightfall, it self-ignites and burns for three hours, flickering as a candle does. The flicker […]
