punter1 Posted May 13, 2013 Share Posted May 13, 2013 Hi, I have a hyperpin cabinet in the works and I want to add some basic force feedback, the flippers, to start off with. I have been reading up on adding contactors withou investing in the ledwiz yet. I have the diagram for hooking up the contactor to the flipper button and i-pac, but I am interested in adding the optocoupler circuit. Does anyone have a parts list and schematic? I see it involves a CNY 17-4 optocoupler but I am not clear on the protection diode or led. What part number for the diode and is the led really needed? Thanks Link to comment Share on other sites More sharing options...
punter1 Posted May 13, 2013 Author Share Posted May 13, 2013 Well after doing some more reading, it looks like I just need - 24v (or 12v) contactor - flyback diode (1N4007) across A1+ and A2- (http://www.sindono.com/project-pinball-installing-flyback-diodes/) - Optocoupler (CNY 17) to isolate powersupply for contactor from the i-pac ( http://wolfsoft.de/wordpress/?p=655) - 2.2K resistor - LED [Edit: Based on discussion added the LED and 2.2k resistor (resistor is req'd - without it, you can damage the optocoupler] for each flipper. If anyone could confirm this, it would be much appreciated. Link to comment Share on other sites More sharing options...
rockyrocket Posted May 16, 2013 Share Posted May 16, 2013 +1 on a schematic for this. Parts are super cheap, just lacking the knowledge. Max where are you?. Link to comment Share on other sites More sharing options...
maxxsinner Posted May 16, 2013 Share Posted May 16, 2013 You rang ?? Punter has basically all the info that you need there with Wolfsoft's schematics to either use Wolf's premade boards or make your own. The LED and resistor that Wolf is using in his circuit is to drop the voltage to a safe level from the flipper switch to the opto-coupler. Did you want a Viso diagram or something to make it a little clearer? Link to comment Share on other sites More sharing options...

maxxsinner Posted May 24, 2013 Share Posted May 24, 2013 Well I was going to draw a diagram but found that the electronics guru Zebulon had beat me to it - http://zebsboards.com/index.php/forum/wiring-diagrams/20-flipper-opto-circuit#27 Link to comment Share on other sites More sharing options...
rockyrocket Posted May 26, 2013 Share Posted May 26, 2013 Sweet thanks!, thats perfect. Link to comment Share on other sites More sharing options...
nromo Posted October 20, 2013 Share Posted October 20, 2013 Thankyou for the diagram, but I still would like to know the reason for the LED after the resistor? I'm going to use 24v power supply so which LED? Thanks Link to comment Share on other sites More sharing options...
nromo Posted October 21, 2013 Share Posted October 21, 2013 While I'm thinking or it, is there any reason we couldn't use solid state relays for this as well? I don't know if they are optical or not, but they do isolate the two circuits and are fast unlike mechanical contactors? Thanks Link to comment Share on other sites More sharing options...
