Nick Mulder Posted January 6, 2006 Report Share Posted January 6, 2006 Hi,I am keen to make the circuit outlined here:http://www.aaroncake.net/circuits/slave.htmit calls for a '2N5777 NPN Darlington Phototransistor' of which I am yet to find a supply of here in NZ - upon looking at the symbol used for the Darlington Phototransistor in the cct diagram in the link above it seems to be two transistors cascaded together one being a Phototransistor and the other a normal transistor...I dont know much about transistors and especially darlington types but if they are simply a bundled package of two transistors could i make a substitute from the discrete versions ?I ask this as I have a simple NPN Phototransistor here already and a PNP and NPN from other projects I could use..is it as simple as that ? :P Quote Link to comment Share on other sites More sharing options...
ante Posted January 7, 2006 Report Share Posted January 7, 2006 Hi Mulder,You could try Farnell http://nz.farnell.com/jsp/home/homepage.jsp nr. 1021141, it should work. Quote Link to comment Share on other sites More sharing options...
audioguru Posted January 7, 2006 Report Share Posted January 7, 2006 In "the good old days", there was a photoSCR that could do a remote strobe-flash, all by itself. I think it was made by GE. Quote Link to comment Share on other sites More sharing options...

ante Posted January 7, 2006 Report Share Posted January 7, 2006 Hi Mulder,I don’t know where I got that number, it should be: 327542, sorry! :-[It's cheaper too! ;D Quote Link to comment Share on other sites More sharing options...
