[PART 1] Official BLF GT Group Buy thread. Group buy officially closed! Lights shipping.

Thanks, just a it paranoid that I missed the payment for the remaining amount.

I'm in for two thanx

I’m in for 1 please.

Welcome to BLF two new members!
Will update the list later!

How is this one progressing? And work from the company on when production may start ?

If you want to play with such a spherical lens, they can be found in every old slide projector that are around on ceilings everywhere around the globe. I already broke one when trying to cut a hole, it will be a major undertaking!

Just a thought…… You might have good luck taking it to a glass company to have it drilled. They should have the proper tools & know-how.

Djozz, I was thinking about those spherical steel domes someone linked some pages ago.

Perhaps it would be possible to drill a hole in the steel, polish the inside until it was a mirror, then electroplate it in aluminum? Steel makes for a pretty bad reflector, but if I manage to electroplate it with aluminum, it might work well enough. Polishing it would be quite the task, though.

Teacher, I doubt I will find anyone with the know-how and tools to do that where I live, but I suppose I can ask around.

On another mod-related note, I got another mail from optolife telling me the A037 lens will be shipped once finished (In around a month).

Maybe the guys at optolife would be willing to cut a hole into their projector lens? They should have the tools required to cut glass, for obvious reasons. If I wanted to ask them, which reflector would be the better choice for a makeshift wavien collar? How big should the hole be?

MARK list updated

In my post #6370 I requested a second Giga thrower, but I don’t see my name listed. Am I looking at the wrong list? Thank you

Sorry I didn’t see it. Thank you very much!!

My bad ‘kaybi’, I did notice your location. Your probably right. :+1:

we need pics and beamshots……… :stuck_out_tongue:

Omg. I’ve read the first 322 posts and can’t see myself getting through another 6000 to find out the final design, and am loving the discussion. But please, can someone point me to the post number with a “final spec”, or a close to final for this light? Please and thank you!

Please put me down for one. Thanks

FYI… I charge my radio control helicopter batteries at 5c a lot, and haven’t had any issues. The better batteries’ get warm, but we’re talking 105 deg F, not much hotter. They are way hotter when they come out of a trex550 flying hard -:slight_smile:

The 1st post gets updated with any new details about changes or any other new details pertaining to The GT.

wondering if the radio controlled helicopter batteries are Li-ion or Li-Po? Haven’t seen one with Li-ion to my knowledge…

While it may work to charge at 5C, it may also be greatly reducing the life of the cells. Most of our high discharge Li-ion’s have a 300 cycle life estimation, where Li-Po is usually 1,000. Charging at such a high rate would effectively cut life expectancy in half or even worse. Recommended charge rates for typical Li-ion is 0.6C, with the newer chemistry being able to take up to 2C. Lot of variables at play, of course.

Hobby RC packs are the pouch LiPOs, not cylindrical.
LiPOs also have only a few hundred cycles of lifespan, not anywhere near 1000 (except for the turnigy graphene ones which someone tested to have over 1k cycles, which exceed pretty much every other lipo on the market)
