- A popular category of aiming/pointing aids is the reflex, or “red-dot,” sight. This system finds use in such diverse applications as astronomy, archery, and shooting. In the reflex sight, light from an internal source typically a ...03-03-2021
- A “swamp cooler” is an easy way to obtain effective air conditioning, especially in hot and dry climates, if a water source is readily available. Although most units are very reliable, the storage-reservoir control usually uses a single ...22-12-2020
- Fan noise is becoming a significant issue as electronic equipment increasingly enters the office and the home. Noise is proportional to fan speed, and the airflow hence, fan speed necessary for cooling is less at low ambient temperatures. Because ...12-11-2020
- Many robotic applications require a sensor to detect close or very close obstacles. Typically, reflective-type infrared sensors are used for this task. But the circuit in the figure 1 shows an infrared close-object alert system built around two ...10-12-2018
- Maxwell Strange EDN Forget to turn off the ceiling fan in your bathroom? Install the simple timer in Figure 1. It's located out-of-sight in the fan unit, and you turn it on via the wall switch. The circuit costs virtually nothing, using junk ...04-07-2018
- Sundaresan Sundararaj Electronic Design This idea describes a white-LED (WLED) driver circuit controlled by a simple ambient light sensor (ALS). A typical application would be a brightness control for cell-phone backlighting. On a very sunny day, ...11-03-2018
- Earlier portal Radiolocman has published a description of two devices for for automatic lighting of the working area in the kitchen: Arduino version and NodeMCU version . The latter, despite several disadvantages, which I will report at the end of ...23-01-2018
- Lance McBride EDN In many applications, it's desirable to disable LEDs used for system verification. Many options are available for the disabling function, including manual SPST (single-pole single-throw) switches, enhancement- and ...05-12-2017
- Part 1 - Arduino Version. Schematic, Sketch and PCB General information Schematic diagram Printed Circuit Board (PCB) Arduino Sketch Highlights Conclusion Downloads References General information The second version of the controller is made on a ...14-06-2017
- General information In this article we will talk about a simple device that I designed for automatic control of additional LED lighting in the kitchen. Kitchen renovating and complete replacement of kitchen cabinetry are main reasons for ...15-03-2017
