Xiaou2:

If you are not intending to purchase a Sensor to track the table...

I came up with a Digital solution, some time ago:

You will need to make 3 of them. One each for the left and right sides of the cabinet... mounted close to the buttons.
And the final one, mounted in the Front of the cabinet.

You will need to experiment with the Mass... to get the right Balance. It should not be easy to Set off... but it also should
not be that Hard to set it off. You want to Slap the cabinets sides, with decent force, to be able to get the mass to move,
which will activate the leaf-switch. The foam is just there to protect the Cabinet from the mass hitting the sides, when it
returns.

Remember that the Tilt Bob, does not sense any particular direction. Its mass designed to start swinging, if the player
moves the cabinet too much. Tapping the cabinet quickly with a bump, often wont cause the mass to move much, if at
all. However, if you slide the cabinet like +1", that thing will be swinging wildly. Also.. if you bump too many times in
quick succession... you might also get it to Trigger a tilt. And of course, if you bumps have too much power in total..
it may also trigger the Tilt. Of course, this also depends on the Sensitivity level of the Bob itself (which is adjustable).

The Tilt Bob is shaped like a Cone... so at its lowest setting... it can move around a lot, without hitting the Ring.
However, when you raise the Bob... the cone diameter expands... making it much easier for the bob to hit the sides.

Anyway... My photo here, is for the Bump detection... not for Tilt detection.

I thought Id add one more thing... About Nudging and Tilting

Im not sure if pinball tables are emulating "Nudging" correctly.

Also, I think some people might not understand the physics, of what is happening.

If a pinball were to roll right down the center of the table... and you tried to nudge it left or right...
Nothing would happen. The ball would not change vector at all.

The is because the mass of the ball, and its Momentum... far out-power the minimal tapping forces.

In order for you to get a Nudge to work on a REAL machine... is that you have to Tap the table at
the same time when the Ball hits something thats connected to the Table. Something Static, like
a Bumper Post, Slingshot, Flipper, etc.

You can test this... by balancing the ball on the top side edge of a Pop bumper... and then tapping the
front of the table... to make the ball move upwards on the playfield.

Then, you can roll the ball down the field... and tap the table left or right... to see if you can alter
its Vector.

The only way to alter the Vector of a Rolling pinball, is if you SLIDE the entire table about an inch or two.
Not a "Tap" but where the legs actually are moved to a different spot.

That kind of table slide, is a "trick-save", that often results in a Tilt. Its not considered a "Nudge", when
you slide the entire table. The Nudge is just a Vibration, that doesnt move the legs/table.

The nudges are used for altering the Vector of the ball. Often the ball is about 2 bounces away from Draining
down the Out-Lane. First, it will hit the slingshots edge... and then it will bounce into the Out-lane. To prevent
this... you can Bump the table Upwards from the front... and cause the Ball to Arc Higher... which might cause the
ball to end up in the In-lane, or another safer spot... where it wont Drain.

The effects of Nudges are minimal, on Fast moving modern Pinball machines... due to the speed of the ball, and
a decent Table Slope.

The OLDER wood-rail pinball machines... have a much milder Rake (table angle).. and so the ball moves much
slower. This makes the ball more "Floaty", and even the smallest of Nudges, can drastically alter the balls
Vector. This is why the old wood-rail pinball machines, have their Flippers spaced much further apart.
The wider the gap between the flippers... the more Nudging skills that you needed to avoid a Drain.

Also, the Older machines had more targets that you were trying to intentionally Nudge Into.

Ond:
You need to read more carefully, anyway, I will update the tilt bob with an adjustable threaded weight. That's a fair enough call. I did my research before making that and do understand how tilt sensors work. As for nudging I'm already using the KL25Z Pinscape unit. In latest virtual pinball software this provides movement data for distance/acceleration etc in any direction. In testing the ball moves very accurately depending on nudge force and direction. Buttons...nup they are done. I'm using silent micros in the flipper buttons and click micro switches in the others. I want them to light up, as mentioned in the thread, I deliberately chose cheaper clear plastic buttons for this reason. I'm doing the last few things now DOF set-up and final touches.

Looking forward to updates, Ond! I really dig how detail-oriented all of your projects are, and the forethought you put into them.

Those are qualities that I do not possess, so I have to live vicariously :lol

Thanks mate, yes it's about time for that update! I've been working at fine tuning controls, flipper buttons mainly, just adjusting spring strength and solenoid actions.
I still have the lock-down bar, main screen bezel, DOF lighting and admin control buttons (sitting inside coin plate) to finish. Also a final spray and touch up on the back-box, decal application on back-box and cosmetic marks touch-up here and there.

I was going to run just with the solenoid mechanical sounds for the flippers but have decided they sound better complimented by in-game flipper sounds in Virtual Pinball. They provide some nice tactile feedback into the cabinet but sound a bit thin on their own.

This Vpin is a 3/4 size machine, not quite a mini Vpin and not full size either. It's fitted with real pinball machine legs which look slightly chunky but cute as well (I think).
This also means it will need to go on a small podium/platform to raise it to a comfortable playing height.

Here's a look at it anyway ;D

The cabinet, just after it was sprayed with primer.

Cabinet after painting satin black. Legs, cooling fans, fuse, PS, on/off switch etc fitted.

Whats inside? Explanatory diagram...

Here's the main monitor (4K LG IPS) sitting in place.

Cabinet glass in place and powered up. Yes it's playable. There is a PinballX front-end and other tables to play of course.

I'm not entirely satisfied with the 3D printed spiders on the back-box (the speaker grills). They are OK at distance viewing but on close inspection well...
I'm going to get them resin printed in white so they are nice and clean and sharp and replace the current ones.
