Here we are talking about a simple way that we can make our submersible pump to start and stop automatically without we touching any button and also we can keep the dry run protection so that the motor never gets damaged. This system will work in such a way that the motor will start or … Read more
In this post we are looking at one cheap Chinese made 12V 1 amp MOSFET based smps circuit. We are trying to see how it is made and also how you can change it to make 24V 1 amp smps or 12V 2 amp smps. This change is possible because the main parts inside are … Read more
So in this article, we are discussing one super simple kind of circuit which is actually a wireless speaker system. We can use this for playing high quality music wirelessly without any long wires, from your TV set, DVD player, iPod, mobile phone, or any other normal music system. That speaker we are making can … Read more
So in this post we are going to see one kind of improved transformerless power supply circuit design, that is having two important stages. First part is a good regulated DC output stage and second part is a relay driver stage which is getting triggered through one outside positive pulse. That full idea was actually … Read more
In this post we try to understand how we can connect some famous voltage regulator ICs like 7812, 7805, etc. in parallel way so that we can get more current from them which is higher than their normal current. Actually these voltage regulator ICs like 78XX series, mostly have their maximum current output fixed to … Read more
Here we are going to see one small but very useful car safety circuit which is actually made for warning the car driver much before the radiator gets overheated. That means that before the car engine temperature crosses the danger level, this circuit will already start ringing a buzzer and inform the driver. This can … Read more
