I wanted to play a couple rounds of centipede and I noticed my trackball stopped working properly.
I'm not able to go up or down again. >:(
The bearings are lubed and both wheels move when i spin the trackball. I switched the little pcb's (that indicate the movement?) around and still wasn't able to move in one direction. :(
So is there a problem with the pcb's (A035220-01), the Harness or maybe with the wheels?
Would be great to get some advice! :D
-
Probably one of the buffer IC's.
I had the same problem.
Let me check the schematics.
-
By the way, this should be in the technical section (bruno ?)
Anyway, here you go:

Tell me if you understand this a bit... first thing: check if F10 and F11 are socketed chips.
-
Thanks, Andre, and indeed wrong section.
You explain the problem quite well, even i can understand it. ;) Too bad my ic's aren't already on sockets. So this will take a while before I'll get it fixed. Or maybe i should start learning how to solder myself. :D
-
i can let you use my desolderstation this wednesday ;)
just get replacement foots sockets and we can install them this night too..
-
Great! But will just replacing the foots fix the problem? Why no new ic's?
Just asking, i found out what an ic is 10 minutes ago. ;)
-
Wahahaha IC=Integrated Circuit = Chip
You WILL need new 4584('s, buy 2 to be safe) if that is the problem !!!!
Can't find them at RS online, I think I bought them at my local electronics store back then.......(www.dil.nl, it's not listed on their site but give them a call they still may have them.)
O and no-one uses the term "foot" in the English language, it's socket. But indeed that's what we call them in Dutch "voetje" :D
Also: No 100% guarantee that it _is_ the IC's. It can also be the opto's.
-
Please note, I think that the full IC number is 14584, not just 4584.
It's a hex Schmitt-trigger.

;D youre totally right, i made a very flat translation :D (and corrected it)

And thats cool about this hobby, we learn every day something from eachoter :spaceace:
Ofcourse new IC's, but that doesnt need soldering/desoldering AFTER we removed the old IC from the CB and installed the sockets
thats something you can do after i helped you with the soldering part..
if you have the new IC's wednesday thats great ofcourse, but my means was to remove the old IC and install the socket so the solderpart is ready and you just have to put the IC's in place.
i maybe need to write more clear :-[ sorry if i was not complete enough in my comments

Searching for 14584 gives some interesting hits on e-bay:
http://shop.ebay.nl/?_from=R40&_trksid=p3907.m570.l1313&_nkw=14584&_sacat=See-All-Categories
Regular suppliers have 0.....
There maybe compatible IC's though...
You can also always ask on KLOV forum (Want To Buy section), a number of guys sell parts there....
-
Wait, forget e-bay:
http://nl.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=5189625
80 cents (ex.VAT) each....no shipping costs.... :D
Sometimes RS's search function is just not working well when you just enter a number.
I found this by entering hex Schmitt and there it was :D
-
and dont forget these :
http://nl.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=0402765&cm_vc=prev_nl
hmm 50 is the minimum quantity..
better a local source maybe if you only need 2...

Never take stamped pin versions but turned pin version instead. MUCH better.
You can recognize them by the circular openings for the pins.
They do cost a bit more though, but for such low quantaties that doesn't matter.
Here's a good deal: minimum 5 at 0.78 cent ex. VAT

okay guys, thanks for the info. Really helpful.
I can't get these locally, all those stores are long gone. ??? So get them from rs.
-
What do you mean "get them from rs", did you order yourself (can you ?) or are you asking us to order ? I'll be in Hilversum early december for work...
-
Thanx on that tip andre!, will keep that in mind next tim i need a "IC voetje" ;)
i can only visit my local supplier, i dont have a chamber of comerce..
-
Another option is to buy SIL (Single In Line, in contrast to Dual In Line) strips of these sockets. You can break them at the desired length. By using two, you also have a "socket". Maybe not so neat, but works great and is very flexible (you never have the right socket at hands when you need it) :D

Sorry for the confusion, I'm really busy atm. :twisted:
If you could get them that would be great. ;D Otherwise i maybe could use my brothers chamber of comerce number.
Again, both of you, thanks for all the help!

Hey Gyruss, I haven't ordered anything so far.
I just happened to also found them on www.flipperwinkel.nl (never mind the name, he has lot's of interesting parts for videogames (or that can be used on videogames) as well !!!
Even the Big Blue will be available from him very shortly.
TONIGHT NO 19% VAT untill midnight because of "Sinterklaas" !!!
Do a search for CD40106 and you'll find them. The downside is shipping costs, but it's only mail envelope costs....not too bad.
Let me know if you still want me to order them from RS else if you prefer, but I'm not sure when you will have them if so....(Hope to be there dec. 20th of course).
-
Hi Andre,
I'll order them myself, and ask Robin to install them. Thanks for you help and hope to see you 20 December..
-
Just ordered the chips!
-
and received the chips ;D
-
you want me to bring my tools next monday and cut them out ?
-
that would be nice and will save robin some work, thanks! :D
-
Cut them out today at gyruss place, and installed the new on the board...
Gyruss, its up to you to update the rest of the story ;)
-
And nothing changed! The problem remains, no up and down movement only slow left to right. >:( >:(
We even switched the connectors on the little pcb's which measures the movement, still no up and down movement only left to right.
Any suggestions?
-
Bump! ;)
-
Bump! ;)
Bump the board to Robin ;D
-
OK, I need a clear picture:
Etienne installed the sockets and the new chips right ?
And if you exchange the connectors on the opto-pcb's you STILL get the same on-screen movement ?
If that is so, I'd think the opto's would be good (since in one sitution one opto works, and after you exchange the other).
Did you try exchanging the IC's ? They are socketed now anyway....
-
I can not test the pcb i have no trackball

2x WRONG, gyruss forget to buy the sockets.... :-\
so i installed them the old fashion way....
-

drop the CP at robin's place too gyruss ;D
-
that seems like a lot of hassle for Robin, I guess i'll start looking for a new pcb

Uhhhh, well it would have been better to wait with that and still order the sockets....
Gyruss, when we have the monitor pick up at your place I can bring my PCB and track-ball and figure out where the problem is first....

Okay, that sounds great, see you sat. 08-01.
