Someone should get that and 3D-scan it!

I'd be interested in a few pairs!

I did have some cables made, and they do have gold (ENIG) plating. There are some problems, but I think they can be made to work (i.e. there's nothing wrong with the connector end).

For various reasons, I left a full copper pour on the back, but that makes them extremely stiff. One of the reasons was to make them thick enough to be tightly gripped by the VB's connector, but it didn't really help, so they're kind of loose (which can probably be fixed with some type of stiffener, such as packing tape). The service I used was experimental, but if you use another service, they could probably add a proper stiffener during the process.

The main problem is that, with the pour in place, it will be difficult to connect them to a display PCB. I had the idea to try to remove the coverlay (similar to the solder mask on a normal PCB), protect the fingers on the other side, and chemically etch away the pour at just the very end.

I'm in the middle of moving house, so I don't have any of my tools or materials handy, but I do want to get back to this project, eventually. I've attached my design (in Eagle) if anyone wants to have a go at fixing the problems and having some better ones made. (Donations of a few spares gladly accepted )

It looks like it's on standoffs, anyway, so there should be no worry about the ESD bag (but, likewise, it won't actually help much, either). Putting a bare board on cardboard is probably not good, ESD-wise, though. If you do much electronics work, invest in an ESD safe surface for your bench, and make sure it's well-grounded (aka "earthed").

(BTW, PM reply sent!)

Very cool piece of hardware!

One piece of advice, do not put boards on anti static bags! The outside is conductive and can fry your board.
People say it isn't that bad, but better safe than sorry. Put it on a piece of cardboard if you are protecting your table ;)


Not trying to protect the table, was trying to protect the board! I'll put it on a piece of cardboard from now on. It usually resides INSIDE the anti static bag so it made sense to take it out and place it on top. I shall no more though!

Thanks :)

Hi, arkleyjoe.

Just to be clear, when you talk about "disconnecting" things, you're talking about the mirror galvanometers, and not the LED display cables, right? The two systems are independently controlled by the VIP.

If the problem isn't in the servo board itself (that smaller board in the "nose" of the VB, perpendicular to the mainboard), it might be that you didn't quite get the sensor clean, the sensor's faulty, or there's a damaged wire between the sensor and the servo board.

The servo boards have been known to go bad. It might be bad caps, but I've never investigated it. I might have a replacement board for you, later, but I'm in the middle of a move right now.

Keep us updated on the situation!

Hi,

I have a problem with my VB. When it fires up one of the mirrors (LEFT) vibrates and hits the stopper making a noise. The other (RIGHT) seems fine.

I have dismantled the VB partially and blasted some compresses air through the optical sensor and checked for any physical obstructions (both suggested elsewhere).

If I disconnect the side with the problem (LEFT) the problem switches to the other side.

Interestingly if I switch the Left and Right ribbon cables the problem remains on the one on the left indicating the problem is probably not with the mirror / optical sensor / solenoid set up and more likely to be on the main board???

All the caps etc looks to be in good shape.

I do not have an other one to test with :(

Any help appreciated.

Joe

So do you have a mini-padder/deflater that you use to convert back and forth?


Any ROM padder, and my ROM shrinker, (located in the Tools Section) should be able to handle that task, given the right arguments for the size (either 8KB or 64KB, depending on which direction you're going). Set it up once in a shortcut or script, and you're good to go.

It's possible to put 16-bit-wide RAM there (or in the Expansion Area at 0×04000000-0x04FFFFFF) and run code from it.

I doubt if your VB is about to fall apart into a pile of ABS dust and electronic bits but, if it would give you peace-of-mind, one possible "fix" (i.e. "preventative measure") for the screw posts would be to wrap a piece of thin string (e.g. fishing line) around the post a few times, tie it off tight, then secure it with a drop or two of a cyanoacrylate adhesive (e.g. "Krazy Glue" aka "Kra-Gl-e").

Reinforcement could also be done with a "3D printer pen" and some ABS filament. Just add a ring/sleeve of ABS around the post, and make sure there's good adhesion between the two. Check that there's going to be room for it, first, though.

I'm not sure I've seen anything like this on the "ports", though. Do you have a photo? Are you referring to the controller, link, and headphone jacks?
