Time Projector Why does my HD projector (Boxlight xp-8t) have to be reset each time I use my Dish Netowork 622 receiver?
Every time I turn it on, it acts funny. I have to turn the projector back off and then back on again. After doing this, I have to change the setting back and forth from s-video input to component input before it will work. Then it is fine. I switched back and forth fine before hooking it up to the Dish Network 622 HD DVR.
I don't know either machine, but it might be worth checking if there is a default setting for either the output of the PVR or the input of the PJ that are causing the problem. Possibly the order in which they are turned on is a factor since some projectors have an auto input select that will sense which input is active and switch to it. Good luck.

How reset time after replace a lamp in Sharp Projector XV-S55U?
Many projectors would automatically reset the bulb use time after replacing. I don't know about this one. Look for a pinhole switch on the bottom.
Yes, it is absolutely worth it. Watching a movie projected so it fills your vision is a completely different experience. It draws you into it, in a way no TV can (unless you sit 6 feet away from a 60" set).
You don't have to spend a fortune, but you do have to spend about $900-1000 for a good setup. And you have to be able to control the lighting, it won't look good in a room flooded with daylight.
Here's a good 720p projector:
Here's a 100" pull-down screen for about the best price you'll find:
Can you project onto a white wall? Sure, but it won't be nearly as good as a masked screen. A screen is brighter, and its dark border makes the image pop, lets you ignore everything else. Which is why you go to the movies.
I was ready to plunk down a lot of money for a 60" plasma. Then I tried my 1280×800 business projector against the wall. It was amazing, so I bought a fixed frame screen. Even my wife, who's never impressed by anything, was wowed. At some point I'll get a 1080p projector, but I'm never going back to a TV.
Hi Tim – sorry, the details of this get very complicated. Delta phi is the separation in the plane perpendicular to the beam pipe. If you look back at my old phi is the angle between two particles in the plane shown in the 3rd picture down – the x-y plane.
If I had told you the amount of work involved you may not have decided to do it and wouldn't be watching that big cool TV!
To answer your question however, the setup I have in the Living Room was off center a little more than that I think as I I had to compensate for one of those stupid ceiling fans. I'm not quite the perfectionist as you, but I can't really see a difference and nobody who has visited has even noticed.
The first answer is good. But have you tried replacing the batteries? The clock might monitor the state of the batteries even though it's plugged into the mains. Battery back-up doesn't work very well if the batteries are dead.
I used to be quite expert on CAMAC modules but that was 1982 and I assumed that they were no longer used. I designed and built the trigger module used in the first double beta decay experiment at UC Irvine. This was a time projection chamber with Helmholtz coils around a sheet of mylar coated with an isotope of selenium. And I did a CAMAC command module for an experiment at Los Alamos (for Herb Chen, it was mostly used to measure temperatures using thermocouples) and also a couple of modules used by a plasma lab to measure small currents and voltages.

Hi, JT here. I recently received a Projection Alarm Clock as a gift and thought that it was just the coolest thing ever. I've started giving them to friends and thought I'd do a little research and put a site together about Projection Clocks and Atomic Clocks. I hope you enjoy!
