    Well here my next project for a customer will be a high end complete rebuild.
    Hmm i woulder could this have been a rare LE Fathtaur?? lmao

    I'm curious to know what the customizations will be.

    #6 6 years ago

    you have a lot of work in front of you.

    playfield looks good, i like what you did the wire braid under the PF, it's different, what did you used for that?

    #7 6 years ago

    Some of the customizations will be custom painted cabinet all automotive, star post will all be lighted and interactive, sound upgrades, adding flashers lighted flippers etc.
    Traces are made from foil tape Ive done this on a few other machines cleans up the PF alot and makes it easier to service

    #8 6 years ago

    Is that foil tape for alarm use, or stained glass use or.........?

    #9 6 years ago

    That foil tape idea is BONKERS. I'm not sure if I like it or not. It sure looks cool, but I've gotta wonder about the current capacity of that stuff, and the longevity??

    #10 6 years ago

    What was in there before? Is it actually wire braid in the early 80s Bally games? I've been working on my friends Meteor lately and the ground on the PF looks a piece of solder lol. This stuff is bound to be better than that right?

    Quoted from vid1900:

    Stained glass

    Quoted from Frax:

    Current capacity is 20amps and is thicker and wider than the power supply traces, the glue is high temp acrylic and meant to last forever realy under stress

    #12 6 years ago

    Very cool.

    I've use that stuff for circuit board repair because the acrylic adhesive is actually conductive, but I've never though of using it on a playfield - very bad ass idea!

    Stuff I used on circuit boards.

    #14 6 years ago

    It was the standard braided soldered everywhere wire
    This method is alot nicer for future work for the sockets will be able to be detached without the troublesome ground braid.
    Realy worked nice on this machine i did a few years ago the base and screw acted as the ground

    #15 6 years ago

    Im digging that foil tape - looks super clean - can you just solder straight to it?
    or no soldering required?

    Stuff I used on circuit boards.

    Pretty much same stuff i use except mine is tinned on both sides i dont want the copper turning black and looking like ass or needing to be cleaned for repairs but Ive used copper tape to repair burnt traces on amp boards etc back in the past when i restored and rebuilt audio equipment

    But why not turn the PF into basicly a circuit board? at least that was my question so i tried it and it worked out better than expected.

    #17 6 years ago

    Just heat will solder the joints but i add solder anyway just to be sure of no problems or shorts.

    #18 6 years ago
    Quoted from Hellfire:

    i dont want the copper turning black

    That particular copper foil never changes color because it has Zinc added to it.

    " Annealed and non-tarnishing, bright copper color" says the label.

    Can't say that about all of them.

    Multi-led rollover insert illumination boards for smooth even rollover lighting.
    Low profile to reduce PF cluster and fit into insert hole under switches

    wow, that i like a lot, can you explain where/how to, if possible. thank.

    #21 6 years ago

    I really like the rollover LED boards. Where can they be ordered or are they custom made? I am about to do several playfield swaps and have been trying to work out a better way to light up the rollover inserts more evenly...

    I love the idea of using the foil tape and not having to deal with soldering each bracket to the ground braid.

    I will be keeping an eye on your restoration for more ideas on how I can improve mine.

    Very cool. What's the story on these? Available anywhere?

    Edit: nevermind, everyone else is already asking.

    #23 6 years ago

    Rollover boards are custom i build them myself, I had a 100 boards made a couple years ago, currently I use 3mm leds and they are a bit of a pain to build atm I need to redesign a smd version for in the future. There are several versions of this board some have bridges for ac another has shunt resistors to eliminate flicker etc.
    Currently making a new style dual color with individualy controlled high power led mod for the saturn bumpers this will be the first machine i use them in.

    Nice. The rollover LED boards are pretty slick. Interesting approach with the foil as well. Can't wait to see how this turns out. You definitely got some work ahead of you.

    #27 5 years ago

    Excellent work. If I ever find a Centaur, this is the kind of treatment it would get. Where did you get your foil tape? You said it was tinned already.

    Also, where did you have the rollover pcbs manufactured?

    I wish I would have thought about copper conductive adhesive tape for pcb repair recently. Ideas about cleaning prepping a toasty board to add that for repair?

    #28 5 years ago

    Not an easy restoration, good job so far

    This is a very cool idea. Thank you for sharing your method.

    The foil tape looks cool. If I was going through all that trouble I would be tempted to use late model Bally/Williams cabinet ground strap. I thought that's what it was at first glance.

    The rollover LEDs are very nice as well. Since you could build that do you think it would be possible to integrate an opto switch in the middle to replace the factory rollover switch and pop up? That would be an awesome upgrade. Getting those pop up switches smooth after clearcoating is a royal PITA. I'm sure you could make a few bucks if you brought a rollover opto switch to market.

    I don't recognize this S&T board. What is this small board on it ?

    Hmm havnt realy thought about it i would suspect making an opto switch would just be overengineered on these sometimes keeping this simple and reliable is the way to go, optos seem to have quite a few issues on pinball machines, more than the blade switches have had then the more parts you have the higher risk for failure. At least that is my opinion on this one i suppose in other cases it might be an improvement.
    The stars were pretty easy to clean out only took about 10-15 min each.

    Im suprised nobody else noticed lol.
    It is an onboard reverb board mod so the crap SIA board will no longer be needed to have the echo voice and sounds on Centaur. It has a longer available delay and better adjustment of the effects than the say it again board did.

    I have run this set up for years in my Centaur 2 and also have one in my Fathom and have plans on adding 1 to my Medusa and possibly Elektra soon as well.

    They have the foil tape on ebay beware the guy selling the 3/8" he is realy selling 1/4" for too much lol

    #36 5 years ago

    That's awesome work! To take all components off of a pcb such as you did and put back takes lots of guts and patience!

    Is it possible to buy one ? I would like to try this mod on my Fathom

    What a great project-coming along nicely!

    Looking good. Nice to see all the practical improvements being made to the electronics.

    Agreed, I really like the electronics bullitproofing and renewal. A real gem this will be.
