4 Solid-State Car Alternator Regulator Circuits Explored
The 4 simple car voltage current regulator circuits I have explained below is created as a immediate alternative to any standard regulator and, although developed principally for a dynamo it will function equally effectively with an alternator. If the functioning of a traditional car alternator voltage regulator is analyzed, we find it amazing that these […]
Automatic Hand Sanitizer Circuit – Fully Contactless
In this article I have explained how to make a low cost yet fully automatic hand sanitizer dispenser circuit which will allow a touch-free or contactless dispensing of the sanitizing liquid on the user’s hands. This contactless hand sanitizer circuit facilitates the user to access the sanitizing liquid on hands automatically without the need of […]
Automotive LED Driver Circuits – Design Analysis
In cars or automobiles, LEDs have grown to be the preferred choice of lighting. Whether it’s the rear tail-lights or the tell-tale indicators in the cluster as indicated in Figure 1 below, all incorporate LEDs nowadays. Their compact dimensions helps versatility in design and offers the prospective to be as durable as the vehicle’s life […]
Gadgets to Protect Women from Assaults and Harassment
Gadgets and devices that are specially designed to repel or deter a potential male offensive can be used by a girl to protect herself from a crime situation, and therefore can be very handy. In this post I have explained a few of these devices which could be either purchased or even developed at home. […]
Ice Warning Circuit for Automobiles
Devices that react to variations in atmosphere or fluid heat are simple to construct due to the easy availability of thermistors. This car ice warning circuit explains how to implement a thermistor like a transducer in a circuit that continuously blinks a warning lamp as soon as the atmospheric temperature drops to around 0 °C.
