LED Beacon.- Pulse generator

By -
Isn't it lovely to have a LED beacon such as anti collision lamp at your home. Is it difficult to build a one. Even I tried to make a one with arduino and found out that we don't need to dedicate a micro controller for such an easy task.

So here we are. I just build a pulse generator. With the simplest parts available in the market.

This circuit is based on 555 timer IC which is set to generate signals with more than 95% duty cycle and a very low frequency . This will exactly looks like a signal tower led which blinks at night.
The generated 95% duty cycle is inverted by the transistor and converts to a 5% duty cycle signal which does the job easily.


This circuit can be easily powered with 3 to 6 volt supply DC. Do not go beyond the voltage level. This circuit was 100% created by me and tested. Any questions. Comment down below.
Have a nice day!

Lab bench power Supply / Voltage regulator with current limiter and indicators / adjustable volage current regulator

Hey! today I am going to show you how to make a lab bench power supply with very important properties.Such as current limiting. I searched in the internet for this but I couldn't find a single solution. So I thought to design a one for me and it worked nicely. So I thought of sharing my design on my blog OK. this is what we going to make. This will cost around 400$ on eBay . i cannot guarantee that u can build the exact thing. But this will make an equivalent This is what i built with my circuit diagram.   Doesn't it looks cool. Still the front panel is not printed for identification of controllers. there are 2 channels on the instrument. Left and Right both are equal and works separately. 1st 3 knobs are voltage, voltage fine tuning and current limiting.And the same for next 3 knobs. 1st 2 terminals are +v and -v for the 1st channel and the next two are for channel 2. bottom terminal is digital High (+5v) which is also and essential voltage output. So lets start

To light a LED we cannot just connect it to mains Voltage. But if we really want to indicate AC voltage with a LED how are we supposed to do it. Adding a transformer or a Switch mode power supply and making a step down circuit will do the job but It is too much. So in this post I will show you how to light a led using only 3 components BE CAREFUL 230V can Kill You! This is the Circuit schematic This is the circuit with the most common types of LED indicators come with. The Diode 1n4007 is an essential part in this circuit. It helps to protect the led in the negative half cycle. any questions.Comment down below
