Voltage stabilizer in the range of kVAs are powerful AC voltage stabilizer units specially designed for controlling and stabilizing high voltage fluctuations, for high power electrical equipment. In this article I have explained an easy to build a 7 stage high wattage in the order of 5000 to 1000 watts stabilizer circuit which can be […]
Newly Updated Circuit Projects:
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 […]
Automatic Door Circuit using PIR – Touchless Door
Along with social distancing and masks, the other major thing the post COVID-19 era has compelled the world to implement is to go touchless. This is being recommended for the many public devices, such as doors, hand sanitizers, buttons, switches etc. in order to restrict the spread of viruses that may be caused due to […]
How to Make a Barcode Security Lock Circuit
A simple barcode security lock circuit or barcode scanner circuit is explained in the following article using just a handful of ordinary components such as an op amp, an LDR and an laser light. We all have seen and are familiar with these arrays of thick and thin lines which can be seen printed on […]
Electronic Scoreboard Circuit Using IC 4033 Counter
A simple multi-digit electronic score board system can be built using a basic 4033 IC counter circuit. The whole procedure is explained in the following article. So far we have learned quiet a lot about this interesting IC 4033 through the following posts that have comprehensively discussed the pinouts and cascading procedures of the chip. […]
Make a Football Electricity Generator Circuit
The explained football electricity generator circuit was developed by me in response to the request sent by one of the readers Mr.Bright. Though I am not sure if the explained concept would actually give the intended results, it’s worth trying as it’s quite easy to understand and build. Designing the Generator There were three things that I had to consider while designing the […]
