What did you mod today?

I’ve used these filters from an old laptop as diffusion film in lights.

Do it Tk! That would be awesome! pics of course… :smiley:

CRX, yeah, well, I’m a little slow on the uptake in some cases (like most times when I’m awake) I ended up with carefully placed discs, 6 of them, and my lightbox reads actual lumens with no math needed. That will be a treat, been using a multiplier for years.
The BLF 348 light measured spot on at 56 lumens, the larger Convoy S2+ that Maukka calibrated at 290.8 shows 288.3 on my meter. No math. I’m not gonna know how to handle it…

The reason is very simple: Djozz still had an old style XP G2 lying around and these can take 5,5A with no problem.
The white flats work on a much lower forward voltage which can cause problems with the driver.
As the TN31 is one the precious few light with magnetic switches I didn;t want to risk the driver.

Also, if you want to make full use of a wavien collar (200% light output) you need to use a dedomed led.
If you use a led with a flat dome (white flat, black flat, XP-L HI, XHP35 HI) the max afficacy you can get out of the led is maybe around 185%.

And yes, having Djozz at just 11Km away is nice, very nice. And he’s a nice guy as well, we get along great.

Cheers,
Nico

Cool DB, it was a laptop that died a couple of years ago so me being me had to take it apart to see if there was any interesting bits I could re-use, tons of wee resistors, screws etc and a big sheet of white film & slightly diffuse transparent polarizing film from the screen.
I actually used a piece of that in the SL.

Here are some pictures going with Nicolaas’ aspheric converted TN42 mod.

I used a precisely sanded to thickness spacer, made of soldered brass rings, clearing the led wires, for the collar to sit on. The spacer was glued to the shelf around the ledboard with Arctic Alumina Adhesive, the collar was precisely centered with the led on lowest setting (and sunglasses on), then glued on the spacer with Norland 64 UV-setting glue. The already glued collar was further secured with large blobs of high temperature hot glue.

Nico is holding the TN42, there’s also a 1 Mcd BLF GT, a 470 kcd 3xdedomed XM-L2 modded Shocker, and a hardly visible 160kcd neutral FT02. The pylon is at a bit over 100 meter to the base, also over 100 tall.

The other pylon is at 700 meter, I did not have a zooming camera (just my phone), but you can see that it is illuminated.

Thanks for the help in modding and posting pics Djozz!

11km away, huh? You two must keep working on throwers until you can bat-signal each other ;)

I like the idea but I see two problems:

1) too many high-rise buildings in the way
2) it would require over 30Mcd throw capacity, that would require an aespheric with a 1 meter diameter main lens…….

So, I probably will have to look for other means to achieve this I guess…… :wink:

If you want to see the signal (and don’t need to be illuminated) you need much less intensity. But to shine through the buildings…you need much more.

A gamma-thrower! Where did I put my cobalt-60 and the electromagnetic gamma-lenses?

Tonight: damaged two optisolis LEDs and a Samsung.

This is my kind of WDYMT post. Sheared domes, bad re-flows, shorting wires. Keep up the mediocre work it makes the average modder like myself feel better sometimes after seeing 10 posts in a row of flawless carbon fiber wraps, custom lathe/mill projects, hand carved pills/centering rings.

We just don’t usually post our f-ups :smiley:

@CRX, how true

I admit, we all mess up sometimes.
A couple of weeks ago i messed up a reflector

Yesterday, like two hours and six or seven attempts to swap an emitter in an AAA sized light that should have taken ten minutes.
Yep this puppy had just about it all that contactr mentioned…
I was almost at the stage where I was thinking the greenish tint wasn’t so bad after all and I should’ve just left it be :smiley:
Swapped out a Luxeon v2 for a Nichia 219C.

Oh gosh, I just mean visible cloud-bounces. Like the bat-signal. At 11km you're starting to get into earth curvature issues for straight line... And probably finding whatever the laser version of BLF is. I don't try to find it because I'd end up with blind for sure

People should post more in the “What did you break today” thread… I like that one :slight_smile:

I’d be here all day if I was to post all my breakages up. :person_facepalming:

Yep, me too, just yesterday tried to build a lighted tail, there’s 6 0603 leds on it but I spent 11 leds (some projectiled on the floor and never found back) before I found there was a short somewhere in the Oshpark board that I could not fix. So I will start all over again with a new board, and probably another 10+ leds before it is finished. :weary:

Oh ya just gotta love a bad board! (Not!)
