A small circuit idea on laser communication using, laser diode at the output of a single stage amp and a photo diode at the input of a single stage amp with a speaker output. Keep both the circuit at a distance only keep a track that the laser light falls on the photo diode. To get best result you can also use audio amp circuits on both the ends.

Hi! Everyone, see the small variation in an OP-amp used as comparator, where one can select the sensitivity of the resistive sensor like LDR/ TDR/ POT/ Force / Stretch etc. Of course the divider network will change with the sensor used. Start building these Circuits and Empower Yourself with the Treasure of Electronics.

One more circuit, stand alone PROM, EPROM copier with blank check and compare facility. In this circuit I am using a 12 bit address generator IC 4040 with 74245 8 bit transceiver IC but used as uni direction only. You can use any 8 bit unidirectional control latch like eg. 74373 etc. To compare the data i am using 74688. Now you can use your concepts for increasing the address bit, getting the output lateched etc.
