Anda dapat mencoba rangkaian yang ada pada tulisan ini.  It uses Low Dropout Positive Regulator LM1084 in TO220 package for delivering variable output voltage... http://elektro.orgfree.com/?p=22 ivica.novakovic writes: Turn ON or OFF electrical devices using remote control is not a new idea and you can find so many different devices doing that very well. For realization of this type of device, you must make a receiver, a transmitter and understand their way of communication. Here you will ... http://elektro.orgfree.com/?p=21  This circuit uses a 1458 dual op-amp to form a radar detector. C1 is the detector of the radar signal. The first op-amp forms a current-to-voltage converter and the second op-amp buffers ... http://elektro.orgfree.com/?p=19 This interface is designed for use with a three axis robot arm based on stepper motors out of 5 1/4" drives. The circuit uses two ULN2803 'drivers' controlled by logic ICs to allow mutliple lines to be controlled at the same ... http://elektro.orgfree.com/?p=18  This is an early picture of my discolight effect. Because of the AGC circuit theres no need for potentionmeters for sensitivity adjust. I replaced them with trimmers. Now the microphone is on the control electronics because theres no need to place it outside the box ... http://elektro.orgfree.com/?p=15
