Where was that posted, I see no topic with that. By the way. I'll continue to spread the word to avoid him in the other forums I frequent for audio. MAK I see its deleted again, it was posted in the CRT screenshot thread on curtpalme. Ill guess he will keep posting stuff like that as long as he can. |

I'm in an intense e-mail back & forth with Mike right now.
He still thinks that Kurt & I conspired against him using the boards I sent to him for analysis.
He thinks that all the pictures the Kurt posted came from his great work.
one thing I'd like to know:
are there others that are nor happy with his work over the years?
he seems to think that only I am the one that was not happy.

Tell him to make things right with you and you will post online of his good intentions in resolving the matter.

It is documented on Curt's forum of my dealings with Mike and his constant lying. I called it out on many occasions and proved it with the emails from Mike. Look for the thread and its contents. He is a waste of time. Get what you can and move on. They are YOUR boards and YOU can do as YOU see fit with them. I hope as the Admin suggests, that Mike makes it right by refunding your money.

Ull never get a single penny out of Mike, he still owe me 1300$, its over 2 years ago, and this is history repeating, his methods is consistent, using lies and excuses, promising to pay one day , and when that day comes up, he will acuse me of something as justification not to pay, and so it goes on and on and on.

he'll never do that.
he wants the boards back, so he can accuse Kurt of having done something to them. but I have pictures of the boards before and after the mods.

You will be sorry if you send them back. There is nothing more to do than move forward. What are you expecting from Mike after what he has posted??? Be honest with yourself when answering this! |

I have offered Nidi to bring the boards to Mike for exchange when i go to get compensate for the goods he stole from me, maybe others like to join, and we can trow a meet of some kind. |

That would work because either MP has the goods to swap or no dice. Kurt, good luck getting anything from Mike on your end. MAK |

MAK He spotburned the green tube, and most likely trashed the projector and moome card, but at least its mine, and i can go get it and trash it, so he dont get to use it. |

So Mike if your reading this, thanks for the compliment, here is a pic of that exact neckboard today, it was in the scrap pile of experimental boards, and it had a rough ride, ill guess the opamp might been changed 20 times, and various resistor combinations, untill i figured out that the BFG 97 is not working properly on these neckboards, with some help from Gjaky, and i moved on to the next board.  Just one word here: I am glad the G2 wire was indeed replaced...  LOL |

Guess who did that, dont think Mike touched that neckboard since 2014 or something like that, i have 2 set of neckboards moddet, 1 time each, none of them worked to my satisfaction, so i used them to experiment with. Today they are scrap boards. |

I did some experiments on the HDM regarding the retrace times and raster ringing. The goal is to optimize 1080p 72Hz (2400 total horizontal pixels) The idea behind this is the following: On stock machines, with maintaining the 2400 total H pixels it is possible to project an image without much ringing only by shifting the image to the right on the raster, which (the raster) is considerably larger than the real screen width. This needs careful setup procedure and generally stresses the electronics more as the raster in horizontal plane much larger than the projected image. To overcome this the retrace time of the H deflection should be altered (lengthen) so the active picture width is just fitting in the active part of the raster. We all know that the raster ringing is in close relation with the retrace time so lengthening the retrace time would improve ringing behavior, plus gaining simpler setup and a cooler running HDM. Now as already known it IS possible to project the 2400 wide frame without ringing so the only question remained is how to get the electronics do what we want... First I wanted to see if the "blanking time" is dynamically adopted or they are preset values. For this I removed C8 and C13 capacitors from the HDM (these are the capacitors for the "long retrace" mode). By toggling between long and short retrace did result in a major crop on the left while in long retrace. If the blanking time would be dynamically adopted both setting would look the same, this did not happen so this is sad. On the next step I reinstalled C8 (only) and intentionally shorted the contacts of RL2 (this does the changeover of long / short retrace), this forced the HDM to operate in a "middle" retrace mode as there was added capacitance to the deflection core but only half of that in long retrace, while the system thought it is operating in short retrace mode. This way the active image filled better the raster (less H-width was needed to fill the screen) but there was still some ringing in the raster along with some spare space to shift out the image from the ringing area. One step closer, this is good! As it looks more capacitance should be added for the perfect result, C8 and C13 are 3.3nF each so I think with another 1..2nF added capacitance the goal could be achieved. I've done some tests and the results are interesting... So I adjusted the resonant caps to just match the raster size to the 2400 pixel wide display timings. And interestingly some ringing still remained -unfortunately. In my book this means the main cause for ringing is not the interwinding capacitance of the deflection windings, and this is not surprising at all since the self resonant frequency of the coils -as I measured- were not significantly different from other "non-ringing" deflection yokes. But then the question remains open still, as to what is causing the ringing then? By the way the projected picture was not affected adversely by the custom retrace time at all (ie blnking worked well, and so on), but the internal test pattern generator certainly was. It looks like the timings are preprogramed in the CLM "assuming" the retrace time based on scan frequency, because I could not see the left-side convergence boxes at all with this modification, which eventually made convergence settings on the left side quite difficult. |

I know that when Nash spoke with Scott (TSE) from VDC years ago about this it was in part due to the length of the coils. For example, the 909 split packs had horrendous ringing. I can't remember if anyone tried altering the length of the coils or not. Steve Flynn from Hi-Rez told me that there was a specific HDM produced for Boeing to reduce or eliminate the ringing though I've never been able to find such an example. Would be nice to eliminate raster ringing because then the only reason for a VP would be the CMS. |

Noticed that Curt Palme, and MP is explaining how the HD10E/ HFQ900 lenses is the best ones.. AGAIN. Wonder how they test lenses, MP dont have HD10E lenses so he is just talking as the wind blows. Ill be happy to ilustrate the difference if anyone stops by, i have 8 set of HD10E lenses from 2003 to 2005, one set in NOS, would so love if they could be used, but of all the lenses i have they are the worse performing lenses except very old lenses from before 1995, and plain HD10 lenses.
And then all the debate about LUG tubes in Marquee.. Not something i would recommend, even im running a LUG machine and have 6 NIB NOS 9518 projectors with LUG tubes. They will work best focuswise with VDC neckboards, but those nechboards are soooo bad in all other regards that its crime, and good luck running VDC neckboards at 200Mhz for a period of time, they self destruct.
