Happy Halloween 2009 - Pumpkin Carving

I have not posted in a while and just wanted to say Happy Halloween to any visitors out there. For your enjoyment I have posted a few pics of my pumpkin carvings for the past few years. Hope you enjoy them!

(2009)

(2008) Poor attempt at creating a "self" carving...

(2007) Fairly pleased with the outcome of this one. I just grabbed a few knives and made it up as I went.

www.MissingCamera.com **Update**

Still working on the site design for www.MissingCamera.com . Thus far the site is fairly usable where visitors can simply browse the current postings for recovered cameras and photos. At the same time you can quickly create a free login to post images from a camera that you may have found. I am still working on the site logo as well as color schemes and layouts, so these items may be ever changing over the next few weeks. Please check it out and tell your friends. Perhaps one of them has lost or found a camera that they may like to reunite with its owner.

www.MissingCamera.com

Purchased www.MissingCamera.com yesterday and am currently in the process of creating the site. The idea came to me after finding a "lost" camera at our resort in Riviera Maya, Mexico on 7/27/09. It was the Dreams Tulum Resort & Spa to be exact. While browsing through the photos on the camera, it looked as if the owners had lost the little blue Olympus camera the night before their departure so my efforts in giving the camera to a local resort worker at the "CoCo Cafe" most likley ended up being a wasted effort. It was at that moment that I thought, "Wouldn't it be great to be able to reunite people with their cameras/memories by the use of the internet?". It was then that www.MissingCamera.com was born. Unfortunatley for this particular blue Olympus camera, I turned it over to the resort in hopes that the owners would check in to see if it had already been located, instead of keeping the camera and posting the images/camera information on my new site. The webpage is most definitley in its early stages, however please check back often for changes and updates. Hey, maybe you have lost/found a camera that you would like to reunite with its owners! Check back often for updates.

How To Remove Dust "Blobs" from Optoma HD70, HD72, EzPro 745 DLP

Just recently I have been experiencing what a lot of projector owners refer to as, "Dust Blobs". Upon researching this annoyance, I had found that there were a lot of projector owners out there who were trying to locate answers as to how to clean these suckers out of their own home projectors.

For those who do not know what a "dust blob" is, it is when a spec of dust lands inside the imaging mechanism (lens and/or mirrors, etc.) of a projector. Some may think, "big deal, its a tiny spec of dust". Well, given the nature of projectors, this pin sized spec of dust gets magnified a billion times then is conveniently projected right out onto your movie screen resulting in most cases as a blurry hexagonal shaped "light " spot on the screen. This spot is typically just a shade lighter than the overall displayed image on the screen and is most noticeable when the video/image being displayed from the projector is black. The size or quantity can vary, obviously, however in my case the dust blob was approx. 5-6inches wide.

At first I tried to look past "the blob" and enjoy the movies however because I knew it was there, my eyes were always drawn to it which would tend to ruin my movie watching experience. This is when I decided to hit up Google for some info but to no avail, it had looked as if nobody had come up with a way to fix the problem. One guy was lucky enough to have this exact issue within his warranty period, so he sent the projector in to Optoma.............then never updated his blog with a status. This is where I come in. I refuse to let a particle of dust, drive me or anyone else to insanity. So I held my breath, ripped apart my HD70 projector, FOUND THE PROBLEM!!! and worked up the below instructions in hopes that it will help you guys as well.

My Google search returned quite a few results of people trying to resolve this issue on this exact model projector, so I hope this helps them out!

Tools:
- Medium sized Philips screw driver
- Small flat head screw driver
- Flashlight
- Cotton swab (Q-tip)


Optoma HD70


Step 1) If the projector was in use, make sure it has been set to cool down for at least 30 minutes to prevent damage to the bulb during dis-assembly. (per the warning label)Step 2) Turn the projector upside down and remove the 2 Philips screws for the bulb cover.
Step 3) Lift up the bulb access cover and gently "wiggle" it outwards and set aside for now.

Step 4) Unscrew/loosen the 2 Philips screws that are holding the bulb casing in place.
Step 5) Flip the metal bulb casing handle upwards and gently pull straight up while "wiggling" the casing slightly back and forth, then carefully set the casing aside where it will not get bumped/dropped.
Step 6) Remove the 3 Philips screws that are holding the plastic front casing of the projector together.


Step 7) Flip the projector upwards so that the lens is facing the ceiling and so that you are looking at the underside of the projector.Step 8) Using your thumbs, put upward pressure on the casing as to push the casing away from you. You may have to wiggle it a little however, once the the side closest to you pops loose you can then slowly lift the front casing upwards and away from the main body of the projector.
Step 9) Once the front casing is free, you must disconnect the wires to the IR sensor by separating the wire clips, then set the front casing aside.
Step 10) If you have a lens cover, (as seen in the photo below) place it over the projector lens to prevent any damage to it.
Step 11) Remove the top 2 Philips screws (circled in red) on the back of the projector.
Step 12) Flip the projector over and remove the following 3 screws which hold the top casing of the projector in place. (2 by the bulb housing and 1 on the opposite side of the projector)

Step 13) Place the projector upright and you should now be able to wiggle the top cover of the projector loose. Note: On my HD70 there was sticky tape on the back left side, (see below in red) which I had to separate from the top cover to get it loose.
Step 14) After you pull the top cover off you will notice a ribbon cable that connects the projector buttons to the main circuit board. Pay attention to the direction in which the ribbon cable is plugged in and then proceed to carefully pull the cable out from the main board then set the cover aside.

Step 15) Now turn the projector sideways so that the main projector lens is closest to you and look for the wire clip below and lens access panel. Once you have found the wires and access panel, remove the wire from the main board so that you have a clear view of the lens access panel.
Step 16) Remove the 2 Philips screws holding the black lens access panel in place. (Removing the black foam piece is optional)
Step 17) IMPORTANT: Make sure the projector is in a dust free area! Then, using your small Flathead screwdriver, carefully pry up the corner of the access panel to loosen it.Step 18) Remove the access panel to expose the inside of the main projector lens assembly and set it aside.
Step 19) I do not have photos of this next process however as long as you are careful, it was quite easy:
a)The main projector display lens is located inside and to the left. (see red arrow)b) Remove the rubber main lens cap that we installed in "Step 10)" then turn on your flashlight and shine it directly into the main lens from the front side of the projector.
c) By carefully looking into the access panel, (photo above) you should now be able to see the reflected light from your flashlight in the the display lens. I created a diagram below so you can understand the point of view.
Step 20) By moving the flashlight up and down and from left to right you should be able to easily spot the dust (tiny bright specs) on the display lens inside the access panel. Note: Be careful not to breathe or accidentally blow air into the main lens assembly.

Step 21) Next, take a clean dry cotton swab (Q-tip) and through the access panel that you are looking through, very gently brush the dust off of the display lens by applying very MINIMAL pressure. Continue this procedure carefully until you no longer are able to see the dust specs on the lens.

Step 22) Once you no longer see dust on the display lens, proceed to cover up the lens access panel and carefully reassemble your projector in the reverse order that we have taken it apart.

Step 23) Your done!! Plug in your projector and try it out!


I had excellent results when cleaning the display lens using these steps and I no longer have "dust blobs" on my screen!

I hope that my time spent putting these instructions together helps you guys out there that have been looking for answers (like me) and could not find them.
