Flashing yellow lights are an essential part of sliding/swing gate and garage door automation systems, since they provide a clear indication that the system is installed and in operation. Thanks to LED technology, the total […]
I’ve recently completed the basic design of a general-purpose analog constant current generator employing easily available electronics components. This is a simple circuit that is easy and cheap to build and is very useful especially […]
Making a micro-LED strobe is much simple than you think. You can simply use a couple of common transistors to build your own LED strobes. I know, there’re countless ICs in front to help you […]
This article covers a simple version of my portable solar power box. In use, it worked flawlessly for me. Although this is a simple version, I am sure someone will be able to improve on […]
Presented here is the basic circuit of an over-current detector built around a handful of easily available and inexpensive electronics components. This simple circuit for DC devices wakes up when the connected output load draws […]
I’ve a few mini pocket weight scales. What I love about the cheap device is that it uses a pretty little load cell. When a scale get worn out, perhaps you can reuse its 4-wire […]
Simple flame supervisor is nothing but a little flame status monitor. The theme of this play is to build a cheap device to provide an alert when the flame under supervision runs out unexpectedly. Admittedly […]
Very recently I wanted a couple of Hall-Effect Switches again for some random experiments, hence placed an order for a bunch of A3144 Hall-Effect Switch ICs. The online retailer quickly delivered the packet at my […]
Any electronics experimenter can connect an analog sensor to a microcontroller and run it with the help of a piece of code. Sometimes there’s a reason to provide a clean digital signal input to the […]
Lady Beetle LED is nothing but a little automatic model toy light, may be a nice Xmas gift for your loved companion. Here’s its tried and tested circuit diagram: As you can see, the circuit […]
