Te digo una mejor idea, haz un disco 🥏 que use bolitas de rodamiento, como los balines de acero que traen los baleros, como los mouse antiguos de computadora y guala, sería más fácil de construir.
Thank you very much for sharing your knowledge and experience. This video has a criminally low amount of views.

From were to buy photo emulsion ?
You can purchase it at a hobby store or on line, you'll need to mix it. You may be able to grab some already mixed from a company that screen prints shirts, but you will need to keep it protected from the sun.
BTW, what reference of optocoupler and triac are you using ?
Hi. When you command a coil with a triac, there is a drop in the voltage. How does this affect the power of the coils ? If the triac drops 2 V out of the 24 V, that's significative, isn't it ?
It was significant only one one coil that was driven from the 6V light circuit. I placed some capacitors in series with the coil to boost the voltage across the coil.
Awesome looking table . Looks like you put in a lot of hours to put that together . Great work I'm about to build one soon . How wide did you make the goal ? I cant find any info about regulation goal width online . Looks like your goal is about 12-16 in. wide . Also where did you get the aluminum rails ? Only thing i can find is flat bar and angle . Thanks for any info.
Thank you. The goals are 14" wide at the narrow. I acquired the aluminum stock from a local metal supply vendor. Most fairly large cities have a vendor that can supply the aluminum stock.
Now i'm trying to figure out how to apply the contact cement so it won't plug the holes up . I'm going to route 48 - 1/4in. wide dado channels horizontal on the play table then drill out the grid on the laminate . Did you brush or spray on the adhesive ? Thanks for your help
I used a roller to apply the contact glue. I didn't worry about plugging the 1/4 in holes. @@82cutty
So you only put adhesive on the plywood ?
Or did you apply to both the laminate and plywood then drilled out the 1/16in. I won't have a problem if I can just put adhesive on the plywood . But I thought it needs to be on both
This whole project is so well done and i really enjoyed the whole series. You did an excellent job documenting everything it took to get this to a finished state! Good work!
I enjoyed your series of videos. I enjoy wood working but know nothing about electronics. Is there an electronics kit available that you can recommend with similar features?
Thanks for the comment. I did everything myself with no kits. You may want to look at Arduino for 8 bit processor kits.
I am working on a System 4 sound board right now and this video was very clean and helpful. Thanks!
Good to hear! Williams corrected the volume pot connection problem with the system 4 sound boards.
Very nice! Is this something you would be willing to do for others? For a price of course.
Not yet. I've been thinking about a better way of doing this and looking for another machine as a test case. If there is more interest, I may make better plans available and may do something with PC boards. What machines would you modify with a scheme like this? Thanks for watching and thanks for the comment.
@@TheHobbyWorldofDrMike I will be in possession of a Bally Wizard! soon. This was my favorite as a yute and will be my first pinball machine to own. It's in really good condition but I'm just worried about long term maintenance that comes with EM's. I like that you basically just changed out the brains and kept everything else original EM. If you didn't look in the cabinet you would never know the difference. The sounds and feel of an EM is to me what pinball should be like. It would be great if someone could come up with game specific conversion kits that could be installed by the owner or technician.
@@TheHobbyWorldofDrMike I've got a decent Rocket III for a Guinea pig
Nice work with the pot!
Great video Mike! I'll have to see the full series now. I'm trying to get into pinball and eventually make a homebrew pinball, but first I'd like to have some experience with how a pinball works and is serviced, and this project seems great for that (not to mention EM machines being cheaper too!). Would you recommend doing this transformation as a complete novice? I have software and electronics knowledge, but I've never touched the insides of a pinball machine.
NICEEEEEEE!!!!!!!!!!
how much did it cost ?
hey man, great effort!
Very cool video Dr. Mike! Loved seeing the calf, we will miss you at MRO but hope you get even more trips like this summer!
Very cool Dr Mike! I imagine there will be much more of this to come starting this summer :)
This is what I was looking for! Thank you very much
The models of blowers I’m seeing are 8.7a, 950ish watts. Does that sounds similar to what you used for a blower?
Hi I have an arcade Elephant AIR Hockey Table. It doesn't seem to give out sufficient air flow to play properly. I have seen alot of videos on TH-cam trying to figure out what should be done to fix the problem. I bought a 1/16 drill bit and drilled holes and cleaned them... Than Light sand the whole things to get it smooth and than clean it off.. its nice and smooth the pucks are fine as well... the blower works great I took it out of the table to see if its work fine and blower is very powerful. Blower is mounted right in the middle of the table underneath it . And where the blower is mounted the air flow is fine there but on the right and left side the air flow is almost non existent... Can u suggest what should I do plz
It depends on how the table is configured. If the blower is pointed straight up to the holes in the table, then more air will flow right over the table. I found that out with a different blower. I pointed the blower I used to the side which generates a cyclone type air movement in the air box. The larger holes in the ply wood also allows for a better air dispersion before the air hits the top laminate with the smaller holes. The blower I used as a 120V, 8 Ampere motor ( answer to prior question) which is far more power than required. A 4 Ampere motor would be more than sufficient and would probably run quieter.
@@TheHobbyWorldofDrMike Thank you for your response. So will an other blower facing upwards or side ways could be the solution to the problem?
@@TheHobbyWorldofDrMikeI wish I could send u pictures of My Air Hockey and Its whole Board etc
😊
Hey, Great Build, What is the Cubic Ft per min air flow of the air blower you have used?
The blower I used has a 120V, 8A motor. Cubic Ft per min is a fuzzy number when the air flow is restricted. The 8A motor is oversized. A little smaller motor would be sufficient and would probably be a little more quiet.
I've enjoyed your videos! I've been considering building my own table but it just hasn't made it to the top of my project list yet. Interesting to see that assembly language! I've been a programmer since the 80's, and I worked with assembly in the beginning, but it's been a LONG time! :)
Great video, I can't wait to see the electronics part :) You guys are awesome, your son is a shark lol ;)
hey cool video DR Mike! Quick question, what language to do use to program the electronics?
I use assembly. The chip I used is obsolete along with its instruction set. I now use an ATmega chips, the assembly language is similar, but not exactly the same. If you use assembly a few times, you get used to it and it really isn't that difficult.
Nice job, great to see some other well set up flash games. I feel these older classics get a bad rap sometimes due to not being set up well, and flash is very difficult to get dialed in for flipper power and drops etc. Your machine looks to be in fantastic shape. Well done. Here's my video if you are interested.. not as nice condition, but I was happy to record a very lucky game on it :) th-cam.com/video/-C1XTVAtPuw/w-d-xo.html
Nice! The Flash machine is a very fun game. It probably gets played more than any other game in the game room.
Very nice indeed! The table look great and plays great. It is giving me the itch to build one. :)
You gotta move to Southern California :-)
