Guest Alun Posted November 10, 2005 Report Share Posted November 10, 2005 Here's something I designed when I was bored, it isn't finnished (and probably never will be).Anyone who can guess how it works deserves a gold star, and the experts like MP and audioguru please don't spoil this for others. ;DVoltage_phase_control.pdf Quote Link to comment Share on other sites More sharing options...
audioguru Posted November 10, 2005 Report Share Posted November 10, 2005 Hee, hee. ;D Nice clever circuit, Alun. ;D Quote Link to comment Share on other sites More sharing options...
Guest Alun Posted November 12, 2005 Report Share Posted November 12, 2005 Thanks audioguru,I've been thinking about this in the back of my mind for awhile but up until now I haven't actually put pen to paper (or mouse to computer in this case). I was surprised at how simple the circuit is, most voltage controlled dimmers use micorcontrollers, I can't believe this hasn't been done before!

EdwardM Posted November 12, 2005 Report Share Posted November 12, 2005 Hi AlunI almost feel a competition coming on, how few components are absolutely necessary for a VCD?Ed ;D Quote Link to comment Share on other sites More sharing options...
Guest Alun Posted November 12, 2005 Report Share Posted November 12, 2005 There is an easier way, you just use a normal lamp dimmer circuit with a LDR instead of the potentiometer and an LED illuminating it but this isn't as reliable or repeatable.

ante Posted November 13, 2005 Report Share Posted November 13, 2005 Hi Alun,No offence, this is just something to compare with! ;DMuch more complicated!DC_cont._dim.pdf Quote Link to comment Share on other sites More sharing options...
Guest Alun Posted November 13, 2005 Report Share Posted November 13, 2005 And surprize surprize, it uses a PIC microcontroller! ;DThis is typical of the voltage controlled dimmers I was talking about before. Quote Link to comment Share on other sites More sharing options...
