WIth a normal tilt bob, though, you don't get any indication of the direction of tilt, which has an effect on the ball in FP and VP (like tilt forward, left right). Or do you not bother with differentiation? Just wondering mainly. I haven't really dug into getting on that working on my cab yet. --- End quote --- My current pin uses 3 tilt bobs, left, right, and center. I just used electrical tape to mask off the section that I don't want the tilt bob to make contact at. On my new Pinball 2000 build, I'm taking a slightly different approach. --- Quote ---Nudging: Nudging will be handled via 3 tilt-bobs, 1 on each side and one on the front. The tilt-bobs will be connected to inputs on the I-PAC2. The tilt-bob rigs out of wood, an adjustable screw & blind nut will be connected to the ground. When the tilt-bob hits the screw it will trigger the tilt. Since the screw will be the only place for the tilt-bob to hit it should be easier to control the motion of the tilt. The screw will allow to easily adjust the sensitivity of the tilt action. --- End quote --- |

I would be worried which LCD units expire quickly in that orientation. I have heard that some LCD's do not like laying flat. |

On the other hand, Plasma screens use a real thin piece of glass that will eventually start to sag in the middle and eventually crack. |

All flat panel displays are vulnerable on their backs. The larger the display, the more vulnerable they are. This is why they, and all large, thin pieces of glass, are shipped in the orientation of their greatest strength in relation to the forces of gravity, on their edge. A horizontal plasma will not crack simply under it's own weight, any more than a horizontal LCD will. But jarring or banging of either in that orientation can cause them to crack. It's probably a good idea to provide some sort of shock dampening mount to any large flat panel display, just to be safe. And under no circumstances should one not use some sort of protective top-glass to keep direct pressure off the face of the monitor. RandyT |

We've had people with pincabs for 4+ years now. I don't think I've read anywhere where an LCD cracked from being in a horizontal position. However, we have seen several plasmas that have cracked within a year. Perhaps since plasma screens run hotter than LCD's it can soften up the glass after extended period of use time. I'm sure it's possible for LCD's to crack from a horizontal position, but the time is definitely longer than plasma. My 42" LCD has only been horizontally for a year now and I've never had any kind of problems with it. It still looks and acts like it was when it was brand new. Most people also have foam tape padding and cross braces to help support across the LCD back. Of course jarring or banging can cause them to crack, but the minuscule amounts of jarring/banging with properly adjusted tilt isn't moving the screen much, if any, at all. My LCD also rides on rubber grommets, so if there is any screen movement it's the grommets that are taking the pressure. Really, only time will tell. I do agree that having glass over the screen for protection is a MUST! Not having glass could cause anything to happen to the screen. So, RandyT - I've already talked to Ultimarc regarding the growing digital pinball scene, but I don't recall if we've talked to you about it. We are needing someone to step up and help develop a analog plunger system. We have the Mot-Ion kit from NanoTech, but getting one is un-reliable as people are waiting about 4 to 6 months for one. Ultimarc stated that there isn't enough market to warrant R&D, but there is definitely a market and it seems to be growing and picking up steam. I think it's a potential un-tapped market that's crying out loud for a GOOD plunger solution. |
