Star trek back online

Yesterday, I've managed to get the Star trek back together

As I (and Pinrepair) suspected what needed to be replaced was the Q16 transistor on the auxiliary (8 - driver board).

Here's the picture of the sinfull pcb, right before installing it.


For the first time in history I now have two fully functional pinball machines in my possesion and I wonder where all this will end.

Bigfoot ramp

I should have put this post together before, but I just couldn't find the time. Here are some pics of how I've fixed the pretty badly broken bigfoot ramp. It took me a whole week to do it, since epoxy glue that I was using takes around 24 hours to dry properly.

This is how it was broken:






My approach was the following:
I've cut out the missing piece from some sort of durable plastics and glued it to some other piece of plastics. This bit came from some old fax machine I found lying around. Here's what came out:


I than glued this bit to the ramp with epoxy. I took me two days, since I did not have enough clamps to do it all at once.



Half way there:


And the result:



I've been using this thing. I just could not find anything stronger on the market.


Luckily, this ramp is almost completely hidden from view, so the artistic impression won't count much, but I bet, this will hold the thing together properly.

Armed and ready

Yesterday I've finished with the playfield. The machine is now in it's full playable form. Needless to say, all the other work stopped for now since everybody want's to play it. Here are some pics of the final steps. There's not that many of them, since I was rushing to get the thing playable ASAP.

Rail attached


Insanity falls is so huge, I had to use a tub to clean it


Installed Insanity falls.


Finished playfield. Boulder garden still missing.


And here's a thing waiting to be done:

Busy weekend

After a long long time I dedicated almost a whole weekend to the Whitewater again. It all started with my friend finally getting the DMD controller back in order. It's been out since these events. It's been all my fault really. I am almost ashamed to tell, but I put the wrong transistor on the Q6 position. I gotta be more careful the next time.

Anyway, here's the result (taken with the phone):


The working display gave me a true rush, so spent almost entire weekend working on the machine. I did the following.

First, I cleaned, repaired and reinstalled the Disaster drop ramp. I also installed the ramp protector and new lock target in front of it. I could not find the originals, but the green ones from TZ look much better than the orange ones.


Then, I replaced the Hot Foot targets with the new ones, both yellow.

After:


Then I disassembled the entire upper playfield, cleaned it thoroughly, fixed what was needed and re fitted it to the machine


I know Bigfoots are not supposed to be very neat animals, but mine is. He's ready for a hot date with the Bigfoot lady now.




I also cleaned and re fitted the Spine chiller ramp and installed a protector for it also.

...and after cleaning

and after, with protectors


and this is where I stand at the moment.


I am determined, that I'll get it in the playing condition next weekend. I just hope I'll find the time to go home.

I will report.

Star trek on it's knees

I had an interesting episode with my Star trek the other week.

I was playing a game, when suddenly it started to behave a bit strange. It was popping the balls out during a regular gameplay, it lost the track of number of balls in play an was being all weird in general. A couple of minutes later a coworker came into room and started complaining about something burning. By that time I was already done with my (weird) game and i noticed that the machine was unable to put the balls into proper places. I also smelled something funny so i turned the machine off quickly. I took the backglass down and to my surprise, it was full of smoke!

After panicking a bit I pulled myself together and dug into the problem. It turned out that one of the diverter coils underneath the playfield simply melted.





What followed in the next couple of days was a classic procedure of:

• traveling home
  
• picking up the needed tools
• finding the replacement coil
• forgetting to pick up some fuses (F103 got burned when the coil failed)
  
• looking for a place to buy the proper fuses in Ljubljana
• etc....
  

Anyway, today I was ready to test the thing and it was also over in a second. The moment I turned on the machine the new coil fired and the next second the F103 fuse failed again.
I am now in the process of investigating, what could be wrong. Pinrepair has a whole paragraph dedicated to this exact problem with the Star trek exclusively, thus I have more than enough info on my hand. At a first glance it seems that some problems with the wiring took down some transistor on the auxiliary driver board, but I haven't found the time to check one or the other yet. I will report on the progress.
