ironspider Posted November 16, 2011 Posted November 16, 2011 Greetings all, I am placing an order with Pinballlife right now and I thought I might pick up my knocker while placing this order for a Williams coin door. So, they have two knockers, the DataEast/Sega knocker for $20.50 and the Bally/Williams knocker for $22.50. So, I guess the first question is if anyone has a preference on either of these or if they sound really different? I will be using the "Knocker Strike Plate" from Piballlife on this build. But, more importantly, I'm running the groovygamergear 12v/5v PSU so I was wondering if either of those knockers will really knock at 12v? Or am I going to have to get a 24v PSU as well? I do want to add a gear motor later but those must run at 12v right? (since they come from cars and the battery in a car is 12v?) Thanks!
DeeGor Posted November 16, 2011 Posted November 16, 2011 I have the Data East knocker, and it's pretty good at 24v. The knock sound produced with 12v didn't sound very authentic. If you want a really loud knock like you get in a real pinball machine, I believe you need to power it with 48v.
maxxsinner Posted November 16, 2011 Posted November 16, 2011 They do draw a few amps so a separate power supply would be my recommendation. I used the Bally/Williams knocker at 24v and it sounds pretty good also. And the gear motor is 12v ironspider.

ironspider Posted November 16, 2011 Author Posted November 16, 2011 Ah, okay. So it looks like I'll be adding a 24v PSU to the list now. Man, this "list" just keeps getting longer and longer! Thanks gang.
chriz99 Posted November 16, 2011 Posted November 16, 2011 I use a 24vdc meanwell psu with 10 or 12A. you can adjust the voltage a bit, so I drive it at 27V. cheers chris [sIGPIC][/sIGPIC] * taito egret 29 candy cabs * indy & star wars pachinkos 17" bartop with ledwiz rgbleds * 10" bubble bobble & galaga bartop * arm champs 2 check out hi-res backglasses * best vpin performance * ledwiz config and software

sacredgaming Posted November 16, 2011 Posted November 16, 2011 The list does seem to get longer and longer its a nasty side effect of creating your own pinball universe.

Man, to be honest though I'm glad it didn't get longer all at once -- probably would have scared me off But now, I'm in too deep. I'm sure by the end of this thing Chris will have convinced me to put a 240v pumpkin chunkin air cannon in my cab for something!

zebulon Posted November 17, 2011 Posted November 17, 2011 don"t forget your diodes across the coils. I know so much about so little that I could teach you everything there is to know about nothing....
ironspider Posted November 17, 2011 Author Posted November 17, 2011 don"t forget your diodes across the coils. Hey Zeb, if I run this knocker at 24v can I use the same IN4007 diode I used across my contactors? Or would I need a different diode?
chriz99 Posted November 17, 2011 Posted November 17, 2011 1N4007 is fine, check out also maxxsinners pinball tutorial 101 cheers chris [sIGPIC][/sIGPIC] * taito egret 29 candy cabs * indy & star wars pachinkos 17" bartop with ledwiz rgbleds * 10" bubble bobble & galaga bartop * arm champs 2 check out hi-res backglasses * best vpin performance * ledwiz config and software
boiydiego Posted December 24, 2013 Posted December 24, 2013 chriz99 what exact number did you use ? because i use the same 24v psu as you also at 27v but when i connect my knocker (blackbeast 22-600) to the psu direct without relay the psu led will dim and knocker does nothing ... do you use a 24v knocker ?
zebulon Posted December 25, 2013 Posted December 25, 2013 Get a 26-1200 coil and it will work like a million bucks. The low-winding count coils are really meant for higher voltages (30vdc-50vdc). I know so much about so little that I could teach you everything there is to know about nothing....
