It has an 1/4” tripod mount, foldable legs would only make it cheaper and more complicated.

2338

Right. I’ll have to buy and carry a tripod.

2339

I’d love if we had even a rough price estimate. Are we talking less than 100, 100, 200, 200+? It will greatly affect how many I buy. If it’s <100, I’m probably in for an additional one or two on top of the one I’ve reserved. (Don’t add me to the list, just making commentary.)

2340

Its still going strong! were just waiting for the engineers as Barry mentioned to me, as they are working on the design. Also still in wait of the driver PCB design.

2341

If there is still enough metal left in the tube its possible, but not sure if the Q8 body design has enough metal to allow the bigger cell size.
a snap on place base may be in the works for added to the accessory-kit that is planned once we get the lantern into production.

2342

that’s agreat news ! :+1:

2343

DBSAR, what are the dimensions of the diffuser cup? For making a more accurate design.

2344

The lens/globe part? ( i can get the measurements for that when i get home.

2345

Yes the lens/globe part.

2346

Kit sounds good I posted here *BLF LT1 Lantern Project) (updated Nov,17,2020) - #2330 by joechina an idea for an reflector, if you want light only in one direction instaed of 360 degree.

2347

I’m interested put me on list please

*Ok some updates: Barry contacted me earlier and they are in need of a base driver circuit design, and asking about the UI (i’m guessing the firmware for the lantern, which i believe Toykeeper is working on that)
I don’t know who designed the circuit board for the Q8, but we are in need of something for the planned two-channel tint ramping, Their engineers are held up on these components at this time, for them to continue they need some basis for what were looking to achieve for the tint ramp & charging system. Without a board design or someone who can help us with that… the only other option is to revert back to using the Q8 board modded with 4-7135s and no tint ramping or charging feature or USB feature. Any input on this form anyone here woudl be greatly appreciated as it seems were held up without a finalized driver board design to incorporate the tint ramping feature, charging feature, & USB power bank feature.*

What’s about DELs driver?
From here *BLF LT1 Lantern Project) (updated Nov,17,2020) - #736 by DEL

2351

I’d forget about the tint ramping and just put some nice 3 or 4000k emitters in it, and call it a day. Strayed too far off the original plan from two years ago IMO. Nice ramping UI, some nice quality emitters and get on with the project.

2352

What he said.

2353

That could be the option right now to get this into production faster. Then maybe down the road a version-2 could be designed with more options.

2354

Or an aftermarket driver upgrade like most of us usually do anyway.

2355

It’s about 90% done but no one seems to know how to do the other 10%.

If the lantern uses a Q8 driver as the base, it needs these changes at minimum:

  • Replace the FET with 4x7135 chips. (or 5x7135)

In order to get tint ramping, it also needs these changes:

  • Replace the original 1x7135 chip with 4x7135 chips. (or 5x7135)
  • Split the LED- pad in half so there is one pad per power channel.

And to get USB charging, using an external board, it should also have some other small changes:

  • Add BAT+ and BAT- pads (CHG+ and CHG-) which connect the charge circuit directly to the batteries.

These are all fairly straightforward changes, so I’m optimistic that they can happen.
