Building a simple radio receiver

By Andrew Joseph     November 22, 2020     projects     No comments   

 


We understood the concepts of radio frequency transmission and electromagnetic waves as a whole, now we are going to put the theory we've learnt so far into practical. We are going to experiment on how a simple radio transmitter and receiver works.

Building a simple dc power supply

By Andrew Joseph     October 28, 2020     projects     No comments   

 


In todays projects, we'll be building a simple power supply circuits to power some dc loads like led light, radios, dc motors etc. A power supply is used to provide either AC or DC step down Voltage with a limited current delivering capacity (depending upon equipment input ) from the domestic main supply according to the equipment’s input voltage requirement .
