AC Solid State Relay
https://www.electronics-lab.com/ac-solid-state-relay/
This simple circuit designed around Solid State Relay S216S02 from SHARP. The S216S02 solid State Relay (SSR) is an integration of an infrared emitting diode (IRED), a Phototraic Detector and a main output Traic. These devices are ideally suited for controlling high voltage AC loads with solid state reliability while providing 4KV isolation from input […]

How to migrate from Microchip to Freescale and Why
https://www.electronics-lab.com/how-to-migrate-from-microchip-to-freescale-and-why/
Maurizio Di Paolo Emilio has pointed us to this latest article on why to choose Freescale mcu versus Microchip ones: The task of choosing the best micro for an application is not made easier by the multitude of suppliers you have at hand today, this being the drawback of having so many options. The main […]
LPG Sensor Alarm
https://www.electronics-lab.com/lpg-sensor-alarm/
sameer @ sgprojects.co.in has build a LPG gas detection circuit based on LM358: LPG gas detection project’s main idea is to implement the security system for detecting leakage of liquid petroleum gas in closed environment. In this project gas leakage is identified by using MQ6 gas sensor. A simple circuit with an Op-Amp IC is […]
Fobble – A general purpose Wireless Breakout Board!
https://www.electronics-lab.com/fobble-a-general-purpose-wireless-breakout-board/
Ken Boak has designed a compact board with RFduino Bluetooth Low Energy Module: This week I have been working on another of my standard footprint 50mm x 50mm boards – it is a general purpose wireless module carrier board:- Fobble. That’s a BLE Fob – for anyone who misses the pun. In the last few […]

m0xpd @ m0xpd.blogspot.com has build a RF probe on a little PCB board. Today I finally got round to building a nice little RF probe kit from Rex, w1rex, the Tuna King over at QRPme. RF Probe – [Link]
ArdLock – Arduino Door Lock
https://www.electronics-lab.com/ardlock-arduino-door-lock/
EswarD2 @ instructables.com has build an Arduino based door lock using Arduino UNO, a keypad and a servo motor. This a door lock built as fun project.It is quite easy to build and a fun way to learn and improve your knowledge of arduino.I tried to add a 16*2 display but there werent enough GPIO pins […]
MAX30102 – High-Sensitivity Pulse Oximeter and Heart-Rate Sensor
https://www.electronics-lab.com/max30102/
The MAX30102 pulse oximeter and heart rate integrated sensor module is claimed as the lowest power solution on the market today The MAX30102 is an integrated pulse oximetry and heart-rate monitor module. It includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. The MAX30102 provides a complete system solution to ease […]
U8plus Smart Watch Quick Teardown
https://www.electronics-lab.com/u8plus-smart-watch-quick-teardown/
sodnpoo.com has reverse engineered a cheap smartwatch he found on amazon: I noticed this smart watch on Amazon for the bargain price of £7.51, which was just too cheap to ignore – I didn’t expect much but I was quite surprised at how functional it actually was… Anyhow, it was never expected to stay in […]
Reverse engineering the silicon in the ARM1 processor
https://www.electronics-lab.com/reverse-engineering-the-silicon-in-the-arm1-processor/
righto.com has reverse enginnered one of the most popular proccessors: How can you count bits in hardware? In this article, I reverse-engineer the circuit used by the ARM1 processor to count the number of set bits in a 16-bit field, showing how individual transistors form multiplexers, which are combined into adders, and finally form the […]
