DTMF based FM Remote Control Circuit
In this post I have explained a DTM based FM remote control circuit which can be used for controlling 4 individual appliances remotely by pressing four corresponding buttons on the DTMF transmitter handset. The idea was requested by Mr. Sunaabh Sarkar. Technical Specifications I came across your blog “Homemade The Designs Just for You” quite […]
Parallel Path Overunity device
In this post I have explained the making of a parallel path overunity device through a few magnets and coils. What is Parallel Path Technology Parallel path technology was first introduced by Mr. Joe Flynn and it’s also called the Flynn’s concept. In this concept or theory, a relatively weaker electromagnetic influence is used for […]
