In this post I have explained a simple IC 555 based self optimizing solar battery charger circuit with buck converter circuit that automatically sets and adjusts the charging voltage in response to the fading sunlight conditions, and tries to maintain an optimal charging power for the battery, regardless of the sun ray intensities. Using a […]
Newly Updated Circuit Projects:
Tuned Infrared (IR) Detector Circuit
The article is a continuation of the earlier post where we tried to find a solution for creating unique infrared IDs for trains in a model locomotive system. Here I have explained the application in detail and learn how it may be possible to successfully implement the idea using tuned IR detector circuits. The idea […]
Cyclist’s Safety Light Circuit – Nighttime Visibility for Cyclists, Walkers, Joggers
A simple flashing bicycle safety light circuit has been discussed in the following article In many occasions when we happen to go down the road at night, it is normal to meet cyclists that are visible only when they might be within walking distance. In case you’re a bike aficionado and prefer to stroll in […]
How to Make a Classroom Debate Timer Circuit
In this post I have explained how to make a simple classroom debate timer circuit which can be used to illuminate two sequentially toggling lamps to indicate the start and finish of the lecture time delivered by the respective members in the class. The idea was requested by Animale. Technical Specifications I’m trying to make […]
Wireless Home Security Circuit – Solar Powered
In this article I have explained a remote controlled wireless home security circuit using which enables the detection of a possible intrusion way in advance depending on how and where the remote sensors are positioned over the selected strategic locations and the desired distance from the house. The idea was requested by Mr. Dave Monette. […]
Beacon Level Indicator Circuit for Combine Harvester Grain Tanks
In this post I have explained a beacon indicator circuit for combine harvester grain tanks. The idea was requested by Mr. John Bosch. Circuit Objectives and Requirements I would like to retrofit the rotating beacon grain tank level indicator system shown below, to my older combine harvester. The particular part of the system I want […]
