Zablon Posted May 15, 2011 Share Posted May 15, 2011 Ok, I have a newb question, but I'm no electrician When bringing a main plug in to power everything, do I run the ground to a leg bolt? Link to comment Share on other sites More sharing options...
maxxsinner Posted May 15, 2011 Author Share Posted May 15, 2011 Oooo Good question Zablon. If you have a mains cable using the bolt as a fixing point for the cable or it runs very closed to the bolts you certainly could put a ground connection onto the 4 legs, but most likely there is almost no chance of the legs getting mains voltage accidentally on them. Legally the requirement is to ensure that all mains are double insulated from possible exposed conductive parts so if all your mains cabling that runs past your leg bolts still have their outer and inner insulation, you should be fine. But if you want that extra protection to be sure, there is no reason why you cant ground all off the legs together then back to your earth connection.

Zablon Posted May 15, 2011 Share Posted May 15, 2011 Thanks Max, I take from what you say that it is not required. I just wanted to double check. Link to comment Share on other sites More sharing options...
maxxsinner Posted May 15, 2011 Author Share Posted May 15, 2011 (edited) Sorry Zablon. Have a bad habit of over explaining myself. Yeah its not really needed but there is no harm in doing it. Edited May 16, 2011 by maxxsinner Link to comment Share on other sites More sharing options...
hicks100 Posted May 15, 2011 Share Posted May 15, 2011 Anyone have an idea how many Amps a standard williams knocker draws? Im thinking of getting an additional 24v psu to drive mine.. (havnt managed to work out how to measure the amps being drawn with me multimeter yet!) Link to comment Share on other sites More sharing options...
maxxsinner Posted May 16, 2011 Author Share Posted May 16, 2011 I dont have a knocker as yet Hicks so I am unable to measure one. (hopefully someone else can help here) But I can guide you through how to test with your multimeter if your interested? Just post a pic of you multimeter or tell me the make and model of it and I will shoot you a diagram of how to test. Link to comment Share on other sites More sharing options...
maxxsinner Posted June 5, 2011 Author Share Posted June 5, 2011 (edited) Don't know why I didn't think of this before. Should be slapped in the face for not realizing it. To calculate the amperage drawn from your knocker coils, measure the resistance of the coil using a multimeter in Ohms then use Ohms law to calculate the amperage. V - Volts that you want to use in DC I - Current in Amps R - Resistance in Ohms Ohms Law - V= IxR So to find the amperage we change the equation to use the numbers we have, Volts and resistance. I= V/R So if your using a 24 volt power supply and your coil is 7.6 Ohms I=24/7.6 = 3.15 Amps 48 Volt power supply I=48/7.6 =6.31 Amps The higher the voltage the stronger the power of the coil, but the amperage rises at the same ratio. Hope this helps a few people out. Edited June 5, 2011 by maxxsinner Link to comment Share on other sites More sharing options...

maxxsinner Posted June 12, 2011 Author Share Posted June 12, 2011 Cheers for the heads up Dazz. Just noticed that myself. Looks like my server is down and so is the hosts website. Will let you know when I find out more. Link to comment Share on other sites More sharing options...
maxxsinner Posted June 12, 2011 Author Share Posted June 12, 2011 (edited) Appears to be a DDOS on clickngo servers. Thier whole hosting service is offline. No doubt it will be back online sometime later today. If anyone is needing a copy in the meantime, I have uploaded a copy to the FTP server /Upload Here/Maxxsinner Edited June 12, 2011 by maxxsinner Link to comment Share on other sites More sharing options...

maxxsinner Posted June 14, 2011 Author Share Posted June 14, 2011 You would not read about it Ozstick. I have had no problems with the service for so long then they went to the proverbial s-house over a couple of weeks. A bit of lost business but no way to get compensation... Enough unhappy customers to almost go bankrupt by the look of it. Wait and see I guess.... Link to comment Share on other sites More sharing options...
maxxsinner Posted June 16, 2011 Author Share Posted June 16, 2011 Just found a US web site that seems to supply all the stuff that I have been refering to. Digi-key has everything from braided sleeving through to slotted trunking (Which I have just discovered is sometimes called raceway in the US) as well as resistors, Crees, heatsinks, terminal strips, everything that a DIY pinball needs. If anyone needs help in selecting parts, either post here or shoot me a PM. Link to comment Share on other sites More sharing options...
gwjrabbit Posted June 16, 2011 Share Posted June 16, 2011 Between Digi-Key and Allied Electrical, I have always been able to find an electronics part. Add in pbresource.com and groovygamegear.com and ultimarc, and you can kind of build anything. Link to comment Share on other sites More sharing options...
maxxsinner Posted June 16, 2011 Author Share Posted June 16, 2011 Thanks GW. I will add these links to the turtorial next update. While we are at it, can people please add some links for those in the UK, Europe and anywhere else that you can think of. Would be great to be able to add a link list to the tut for everyone.

Dazz Posted June 16, 2011 Share Posted June 16, 2011 I personally use Digikey and Mouser.com. Pbresource has been great for my EM stuff, but for newer pin stuff I use Pinballlife and Marco Specialties. Link to comment Share on other sites More sharing options...
gwjrabbit Posted June 16, 2011 Share Posted June 16, 2011 I've definitely ordered Arcade parts from Marco, but they tend to be a bit expensive, especially on shipping, in my experience. Link to comment Share on other sites More sharing options...

DeeGor Posted June 28, 2011 Share Posted June 28, 2011 This guide was extremely helpful, as I knew very little when it came to electrical wiring. Thanks to all for putting this guide together. Link to comment Share on other sites More sharing options...
