This project simply switches the system OFF or ON whenever the temperature rises at the desired set point.  The desired setpoint can be set using a fixed resistor R6 or PR1 trimmer potentiometer. Use any of at a time R6 or PR1. You can calculate the setpoint resistor R6 using the...

Touch sensors are used in many applications, from remote controls, LED light controls to appliance control panels. This is a simple solution to replace the mechanical buttons and can be implemented in a wide variety of applications. The sensor provides great user experience. It is easy...

The project published here is a solid state power switch with current limiting that prevents damage to host devices from faulty load conditions. This analog current limit switch have low on-resistance P-channel MOSFET and INA202 driver IC from Texas instrument. The project operate from...

The electrons movement in electronic components lead to the generation of heat which when beyond certain thresholds, prevents some components from functioning properly and in others could lead to a catastrophic breakdown. For this reason, the topics of ventilation, overheating, and...

Last time we examined how to build  a DIY Reflow Oven controller using the Tiny Reflow Oven Controller v1 by Rocket Stream. However, Rocket Stream recently released the Tiny Reflow Controller V2 and for today’s tutorial, we will attempt to build this second version. The Tiny Reflow...

This article describes the electronics, the BL600 program and the Android program; the last being an Android smartphone application with which your mains switch circuit may be controlled wirelessly. You may notice an unusual detail for these pages — the transformerless power...

Clever way of starting-up relays discussed in this app note from Maxim Integrated. via dangerousprototypes.com Relays are often used as electrically controlled switches. Unlike transistors, their switch contacts are electrically isolated from the control input. On the other hand, the...

easySwitchBox by easySensors is a long-range LoRa® wall switch powered by coin cells and the Arduino IDE. easySwitchBox enables you to remote control your appliances from long distance as easy as the push a a button. The easySwitchBox does one simple thing – it sends on\off signals...
