Hey guys, why not have a LL nobel prize for innovation! It doesn't have to be anything special. Just some recognition for those of us who have shown great innovation in our builds that others want to emulate in theirs.

As an example, Haas Man's design is so innovative it has its own name, the Haasman pj. It's all the rage!

So, I think Haas Man deserves an LL Nobel Prize for innovation!

Prizes can be given to people who help solve different problems or who incorporate innovative designs and engineering solutions that others try to emulate.

The first person who can figure out a way to clean fresnals of fingerprints and oils definitely deserves a LL nobel prize. Any takers?

Hmm...nobel prize winners recieve a million dollars. What do lumenlab nobel prize winners recieve? A free pro lens kit?

I don't know. Maybe a pinned "special thanks" thread or "Lumenlab hall of fame"

In my oppinion they would include brain, joechevvy and maybe haas man. (maybe because while it is very pretty, it has no effect on the projection itself) but he does deserve credit for such a beautiful design.

Well, my criteria is anything that a lot of people would want to emulate.

While practicality is important, this is a luxury item and aesthetics is just as important. Otherwise we would all just use the simpler OHP design and save about $200.

But, then again, that is just my opinion.

"this is a luxury item and aesthetics is just as important."

Your entitled to your own oppinion but I must say I can't agree with you there. First the lumenlab design works better then a simle ohp design and second, I'd put a projectors technical capabilities a thousand levels higher on the priority list then how pretty the box looks. Sure the haas encloser is a beautiful design but I'd rather use a projector built from chicken bones and dirty underwear if the projected image looked better.

Its the image your looking at, not the projector. The projector will be behind you, in the dark. The cosmetic appearance of the box is mostly for when the projector is not in use, so it doesn't look like a piece of crap lying around.

Appearance of the pj is probably something that makes or breaks whether or not people decide to build one of these. Let's face it, one of the major disadvantages to the LL pj is the size and appearance. The haas pj would not be as commonly copied if it was not very important to people. Both Haas and Joe created designs that allowed a much more asthetic looking pj without having to sacrifice quality at all. These two have changed the way the LL pj is made, and recieve my Nobel vote for their design changes.

I would say any nobel prize should go to the person(s) who figure out how to utilize the Pro lense effectively.

I agree with Mikau, while haas' PL looks really kewl, but what's innovative about it? it uses the same components as all the other do. It's just prettier.

Here's how I cleaned my fresnels.

Canned air, blow.
Rinse under tap, egads!!! yes.
Use a little dishsoap, very very little, soaped in hands, went around in circles while still running water. Canned air to dry. A bit, placed by window

Could we call it something other than the Nobel prize? Maybe the Phutton Prize since you thought of it.

Nobel is not a name worthy of a Lumenlab projector(IMHO).

How about something like "Most Innovative Concept Award"?

I say we should have awards for different categories like, best picture quality, best light box, best box design, ect....

Sorry Ferris, no cigar on that one. What we need is something that will really clean fingerprints and stuff off. That method works pretty good with a relatively clean lense, but I don't think it would work with a dirty one. As a matter of fact, I know it wouldn't because I used it myself.

Then again, maybe I just used the wrong soap.

Good try, though.

I just use cloth gloves when handling the fresnels.

Phutton, got an idea for fresnel cleaning. Gasoline? Gasoline will get tar off your hands so it will probably get finger oil off plastic. Just make sure you dry it well after. Somehow putting a gasoline soaked fresnel in a box with a 400 watt lightbulb just doesn't sound right.

Turpentine may also work.

Mikau, ever wonder why they won't let you use a plastic container when you go to buy a gallon of gas?

You have to be careful with certain solvents and plastics. The wrong combination can cause disaster.

While I think it is great that everyone tries to help each other out, I think it would be more beneficial to only post suggestions that you KNOW to be true, instead of suggesting things because you would like to have an answer. Our posts should really be of things we know from experience, not that we have just read or think. Not to pick on anyone, but had someone tried to clean their fresnel with gasoline, it would have been disasterous for them, not to mention that it may have caused a fire in their pj.

Well I feel stupid.

I apologize for that. It was just an idea. I had no idea gasoline had any effect on plastic or any other solid material. Had no idea mixing gasoline and a solid material could be dangerous. I'll remember that. And once again sorry for making such a dangerous suggestion. My bad.

But in my defense, evertime I used gasoline it was inside red a plastic container. I guess that isn't plastic, or a special kind of plastic.

Yep, red plastic for gas, blue for kerosene. The plastic containers they come in are a variation of food gade plastic. Its designed to be chemically nuetral and also to withstand pressure by being more pliable at high temperatures. The walls have to be a minimum thickness for each unit of volume in the container.

Now to remove fingerprints from the fresnels....409.

Spray with 409, allow to get into the grooves, let sit for 3 or 4 minutes, the rinse clean under a tap and then follow with a rinse of distilled water. Dry with fresnel grooves down.

Why use tap water (with all its inpurities) and then distilled why not just distilled???
You don't want water spots on your fresnel!!!!!!!!!

I guess that I'm showing my age, they used to have to be metal containers but I forgot about the specially formulated newfangled plastic fuel containers. But, as samuraijack said, not just any plastic will do.





You might not be able to rinse off the soap as well with only distilled water(just a matter of volume). A final rinse of distilled will work fine to remove any remanant scale left by the tap water.

I'm still miserable. I almost sent phutton to his grave!

Think nothing of it. My fire insurance covered my garage. Blue cross is covering my skin graphs.

Hospital grade morphine is great, dude!

lol!

Well sorry anyway.

But you would have needed fire insurance for yourself, not for your garage.

Whoa, what the hell happened?

Yep it was rupturing gas cans left in the sun and in car accidents that prompted the mandate for the new materials. That and plastic was cheaper....
If you leave one of these in the sun now, it gets really big and will try to swell like a balloon, but it stands less of a chance of rupturing. Same for car accidents. If I remember right, there was a move to replace metal tanks with plastic ones. No more tank rot and it could handle the pressurized gas systems more easily. Dont know where that ended up....


Yep. Distilled water is kinda expensive, but feel free to use it if you like. Some of the astonomy folks I know use "deionized" water. The reason I suggested tap first is that 409 likes to have a good wash to enable the emulsion of the oils from human skin. Sometimes a little squirt from the sprayhead helps this along. But distilled water is excellent.

Phutton wanted a way to clean fingerprints off the fresnels, I thought "why not use gasoline?" because it will get tar off your hands so it should have no problem with finger oil. But appearantly mixing gasoline and plastic is a dangerous combination.

What does it do anyway? Produce some sort of toxic fumes?

There are two issues.

a) Gasoline is flamable so there is a fire danger.
Some solvents can melt, cloud, make brittle or other bad things to plastic. There are millions of different types of plastic so some are tolerant of chemicals and others that are designed for certain purposes like being clear don't have these sorts of characteristcis. So beyond the fire issue I believe that he was saying that it might damage the plastic, might not but do you want to risk it???

Did you know that resin/epoxy will melt styrofoam?

Mikau: Yup. I know. So will Testors model paints.

Thats a perfect example, when I was kid I went to a summer camp and they were creating a huge bondfire. They took a red can of gasoline and poured it into styrofoam (a type of plastic) and threw that on the wood, but after a couple of fills the cup just melted in his hands and he ended up pouring gas all over himself.

Samaria,

I'll try the 409 on my dirty fresnals and see if they clean up reall good or not. I'll let you know. If they do then I think you will have solved an real big problem here.

Did you get hurt very bad?

Thats actually part of recipe for civilian grade napalm. The gas provides the combustability and the styrofoam supplies the bonding and carrying agent.

Beat me to it samuraijack.
I was thinking about this fact as I read this thread.
Reminds me of the Chem lab days in college.
Oh... what fun that was.

No blake, I was just kiddin around.

But thanks for your concern.

Re: I can't quite remember why ...

This may seem like a dumb question, but what is 409? (to a non-american)

Great nominations. I also nominate Haas_Man for having the best projector box design.



Heh , here you go....
(hehe funny that pic is from doityourself.com, what are the odds....? )

Just in case the pic didn't communicate it's use, 409 is an all purpose houshold cleaner for use on countertops, stoves, sinks, etc.

Maybe the first 408 mixes didn't work???

if the 408 mixes did not work then 409 is my lucky number

y not use mr. cleans autodrying car washing spray thingy:P

i have 2 of them
im gonna try it later im about to go to bed. i will try it in the mornin

http://www.homemadesimple.com/mrcleanautodry/products.shtml

it has water
it has that spot free water filter

this is just wut we need



how about bambam's focuseing box, i think that was a good idea
