We have a family of porcupines that like to come over and chew the sides of our shed. The glue that they make T-10 out of is quite yummy to them...
You can always tell when they have had "Dinner Out". Our deep grey shed, with fresh brown wood bites out of it...

have you tested your lcd yet ?

No, but I've looked longingly at it several times and shed a few tears. Soon . . . soon. (In geological time that is.) We have that trouble too. I once went to the local farm store (Agway) and asked if they had anything to put on wood siding to prevent animals from chewing on it. They gave me this look and said they'd never heard of such a thing as animals chewing siding.

LCD ( in this case...) stands for Lustilly Considering Doing-it....

Behr semi-solid stain seems to deter them. They dont seem to like paraffin.

gawd dont come downunder,,, the cockatoo's here will eat the woodwork from under ya,,

have a balcony,, with railings and traditional ornate balls on posts,,, cockies greatest 'joy' chew the bottom and watch ball roll down driveway, they fly off screeching and laughing, leaving you with a woodwork bill to fix it


and Durako,, its time tyo move on and Finish your PJ,,,,,,like the Nike add says JUST DO IT !!!!

hah! you guys have obviously never dealt with mice in the kitchen and a wife who is positive she is going to get the bubonic plague or hanta virus from them...shes got the mask on, gallons of bleach, the cdc site is up on the computer.... I told her I may get her a hazmat suit for her birthday..and she didn't think i was a bad idea...she'd have a heart attack at you guys' houses

what ???? Everyone doesn't have a Hazmat suit at home.
Mikyd I feel ya pain. Really!! I should buy stock in clorox wipes.

You guys quit discussing your personal hygiene habits in my plog!!! :angry:

I'm the only one allowed to do that here.

Inspiration to get back on track. One of the first, new DE lamps from Lumenlab. I'll fire it up ASAP and get back to building.

These should be released to the general membership in the near future.

Edit for posterity: These lamps never made it into Lumenlab stock.

oh sure, increase our enviousnessss with your new bulbitude.... hey... were the salts in that one red when you got it like in the new t15 lamp? (well, at least one person posted a pic of red salts in his new t5 bulb)

No and that is really a point of confusion for me since I fully expected the red salts.

So, I'm always confused anyway and perhaps I just don't truly understand what this bulb REALLY is.

I was kinda wonderin' who'd pick up on that.

Where shall I ship your cigar?

Or would you prefer a Kewpie Doll? (spelling?)

I've learned to be really observant over the last couple of years "Gee honey, the house looks great, you dusted the molding again I see" .... as if....

ROFL
Mikyd..Your wife and mine must be related.

And "MR D" that's a mighty fine looking bulb if I must say so myself. I am really digging the size.

I think I need one of those for PJ #3.

Fired the DE with my M135 last night. Fired immediately and ran stable. I'm unclear on the precise feeding requirements of this lamp though.

Already working on getting my pre-con installed and getting back on track with my build.

I will mention two things I noticed:

• The M135 seemed much noisier running this bulb compared to the Ushio T15 PS (no longer sold here).
• This bulb really created an odor I would call ozone-like. I always use sunglasses or a welding helmet whenever I might expose my eyes to the unshielded lamp emissions and my eyes were irritated by this lamp somewhat when compared to the T15 PS. Just something I wanted to note but I don't think it's gonna be a problem in the long-term. Time will tell . . .

that smell goes after awhile,,, this HQI did same thing two years ago when fired first two times,,, its the U/V reacting with the quartz

AND dont look at the bare lamp especially the first few hours,, it will settle

Durako,,, can you get a spectral line chart of it at all?

Been digging like crazy trying to find our little gizmo(s) for doing that but I can't seem to turn them up. I continue to search . . .

May have to break down and make an elkenoscope!

That or bring my junk to work. :angry:

Lookee, lookee!!! Found something I didn't even know we had!

A Bausch & Lomb Spectra Projection Kit.

Sweeeeeeeeeeeeeeeeeeeeeeeeeeeeeet...........

Time to plaaaaaaaaaaaaaaaayyyyyyy.........

Pretty much simply a diffraction grating of 600 grooves/mm.

Unless I find one of the other self-contained gizmos we have/had I'll make do with this.

Just gotta figure out how to set it up for optimal results.

My turn.

Growing up on an island out in the pacific ocean we have problems with brown tree snakes (nonvenomous to adults) crawling themselves into our homes. Grabbing their tails and immediately whipping them around like a cowboy prevents them from striking most of the time. Must have killed 20 during my years and bit twice.

anyhooo, carry on.

Get a video!!!

Here's a quick test of this diffraction grating I discovered. This is of an EKE 21V 150W fiber optic light source lamp.

HEY..pink hearts, yellow moons and green clovers...."ther all afer me luckie charms"
Sorry its just what it reminded me of.

Rem: Get outta here and work on yer PJ while the wife and Nerd are gone! I'm jealous. :angry:

Jerked the T15 PS outta my lightbox last night and came up with a quickie mount for the new DE.

I'll bolt the sucker to the side of my lightbox on a couple of pieces of tubing which will allow for some adjustability.

Got my condenser holder figured out as well. Maybe today I'll cut that out.

No.. what I'm jealous about is the Rockin Lamp in your lightbox. Whoaaa.....it just looks beautiful.
Makes the box even look cooler too. I really hope it performs well.

hmmm... you know Durachko. I just may sneak out of work early and work on the PJ. Maybe go to lunch and not come back. HEHEHE

DO IT!!! Next week I think I'll play hookie a bit as well.

Light box looks great, might have to steel some ideas from that to use on mine because its actually a very good idea! well done

Just fix all my mistakes and it should be really good.

Seriously, I think those "heat baffle" double walls I installed are not necessary.

Sweet looking lightbox D. The words Twin Turbo popped into my head.

Thanks for the compliment. Initially I wanted the redundancy of two fans but later thought it might be nicer to blast the back of the pro-reflector to keep it cooler. Plus, the reflector would act as a nice deflector to direct the cooling air around the bulb and not directly on it. We'll see how this really pans out in the end. I'm contemplating a little overclocking of the lamp so I'll have to play it by ear as far as how hard I drive the dual fans. Just hooking 'em in series instead of in parallel dramatically lessens their noise. Thanks again Sim.

Working on pre-condensor lens mount. Made a template then transferred reference points with a punch to a sheet of metal. Cut it out with a bandsaw and nibblers and now I've got a mount. I'll "hang" it off 3 or 4 screws going through some L-brackets fastened to the sides of my lightbox to make it adjustable.

Ahhhhh... very nice.

Nibblers... wish I had thought of that long ago... a metal cutting device that is affordable ! (I don't do much metal work so never think of these things)

Do I see this correctly ? 3 tabs hold the lens from falling through, and 3 tabs keep the lens centered ?

cheers,
gs

Thanks. I was really happy with this when I thought it up. I think it's very elegant. Simple and elegant.

Nibblers rock. They are slow though. Not really all that bad for one-offs.

I keep bugging my brother-in-law to buy a CNC plasma cutter and go into business making lightboxes for Lumenlab on the side.

Yes, 3 and 3 tabs. Three points form a plane. One of my favorite sayings. I neglected to spell that out in my very terse description.

Hope it works okay. See no reason it won't.

I purposefully put some fingerprints on the condenser but they don't show well.

Nibblers are the best thing since sliced bread.
DC that a sweet looking mount. Are you planning on holding the lens down with something off the three upright tabs or are you thinking of letting gravity do the job? Or maybe just bend the tabs over slightly? Just wondering about moving the thing when its done...

Still...its very nice!

SJ

Ahhhhh..Durachko you have been holding out on us. Your fabrication skills are top notch
With this skillage we want to see a fully operational "PJ" soon.

Oh, and yes I did play hookie from work the other day

I mulled it over and finally decided if gravity fails then I likely won't be watching my projector anymore. I may have a change of heart but I think it'll be fine. The lightbox should never experience any harsh movements. (Famous last words?)

well, now I know how to mount my 6" lens when I get it.... nice work chachi, oops I mean durachko...

Everything gloriously assembled minus the iris.

Will try to fire this at ~500W with an S51 ballast sometime in the near future.

Groan . . . remember the black snake in the rafters? Damn timber rattler in the same shed this past weekend. Now that's enough to give me the willies! Our house is situated on prime habitat so it's not uncommon for us to see one but having one sunning in the door to my woodshed is a new - and not particularly welcome - experience.

Very nice looking light box! you've been taking lessons from pun15her. you might just get your PJ built one of these days. (pig wing roast is at your house)LOL.

TESCORP you are way too kind. Comparing me to the likes of pun15her is truly an honor I do not deserve. But I'll take the compliment anyway! I think tonight I'm gonna fire that FC2 up @ ~500W. Anyone up for Buffalo Pig Wings?

you're too modest my friend, I couldn't do something like that no matter how long it took me...right now I'm looking for a bud box I can tun into a ligt engine...are you going to add the precondenser?

It's in there you ninny!!!!!!!

See how the arc tube looks magnified? And how can you miss that beautiful pre-con holder? Painted black it blends right in I guess.

I'm intrigued by that post today whereby someone found moving the pre-con pretty far away boosted their lumens by 40 or 50? I'll halfta play around.

MOTH BALLS
Now don't be chasing around those little flying things...just head down to the ol Wal-Mart and pick up a box.

A little known fact that it will repel snakes and keep them away. Of course it will prob smell like your grandma's house to but hey life is about choices.

Hey did you fire that light up yet?? What we waiting for, an invitation?

Thanks for the idea. How many moth balls? Dang but they must be teeny-tiny little things.

And how do you tell the males from the females? Ah, if they've got 'em at WallyWorld I don't have to worry do I?

Gonna try like heck to fire it tonight and test my fallen-in-combat LCD. Keep yer fingers crossed and don't step in any more potholes Remmy!!

(I've had reasonable success with moth balls repelling mice but never thought about the snake thing. Thanks again.)

Edit: Yer gettin' long in the tooth. Use the nerd as a hole probe. Kinda like a seeing-eye-nerd?

DOH! I need new glasses, I can see the 3 tabs but not the lens, ah well.... yeah I saw that too, I may play around with mine too .....

I tricked ya by wiping off the fingerprints!

that and no sawdust threw me off...everything in my lab has sawdust on it....

keep it coming, .. interested in understanding why you choose a 330 fresnel + precondenser vs. a 200 (which is what i have)?

"The spread BOSS, the spread.... is much better!" But really, depending on the focal of your precondenser to be used with the 220mm fresnel. I've tried with a 12"fl precon and 220mm fres and preferred the 6.5"fl precon with the 317mm or 330mm fres. Arizonavideo did find a 9"fl precond seems to work well with the 220mm fres. It's really a matter of personal preference but the 220mm setup should give you more lumens because the light source will be closer to the fres.

Now, with regards to the mothballs and snakes, wouldn't it be easier and more effective shooting them with a .22 cal then throwing mothballs at them or did you DIY a potato gun for this?...............JUST KIDDING!!!!

Now that you've teased us with that nice looking light box, any sneak peeks at the enclosure its going in to?
