In this design a solenoid is operated using an IR remote control, which in turn toggles the fish feeder mechanism. In this article I have explained how to make a simple infrared controlled fish feeder circuit. The idea was requested by Mr. Harishvar. Technical Specifications I just want a circuit which should turn on when […]

How to Connect a TSOP1738 IR Sensor
TSOP17XX series devices are advanced infrared sensors having a specified center frequency of operation which makes their detection extremely reliable and foolproof. In this post I have explained how to connect a TSOP series infrared sensor and use it for a specified IR remote control operations. TSOP IR Sensor Specifications A TSOP series of IR […]
2 Simple Washing Machine Circuits Explained
In this post I have explained how to make a couple of simple washing machines using a bidirectional single motor with timer and a simple version using cam shaft mechanism, cheaply. In the first design we use a bidirectional, alternately rotating clockwise and counter clockwise with a pause in the middle: Audio/Video Representation Circuit Working […]
Borewell Motor Pump Starter Controller Circuit
In this post I have explained a circuit which controls a submersible borewell motor by operating its red (Start) and green (Stop) buttons, in response to low level, high level water conditions, and also in a condition where the motor may experience a dry run situation. The idea was requested by Mr. Vamsi. Automatic Start/Stop […]
Make Free Drinking Water from Sea Water
In this post I have explained a cheap yet effective method of desalinating large quantities of sea water into free drinking water at home. The idea was requested by Mr. Mike. Technical Specifications This is Mike Cardenas and am writing to you with reference to your invention of a Solar Water desalination set-up from 2011 […]
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. […]
