Does Neal have interest in doing the Aux boards as well? That would be pretty cool. He could even include it on the premium FW3A models

Can this driver be used also in other e-switch flashlights, assuming you would connect the e-switch to the inner ring on the back?

The multi-color aux leds are really an outstanding feature.

I assume so, and that’s what I was thinking of doing for some other lights, the via for the switch ring seems to start here :

Probably a bit small for soldering a wire there, but there is a tiny bit of space up north without components (blue) to make yourself another via.

Or even better loneoceans could add a solder pad for the switch, unused for the FW3X, but would allow to use the driver for other lights where it fits.

Neale confirmed on FB that he will sell FW3 driver and AUX boards also.

Spring should be included cause partially finished products are not attractive...

It is possible to use this driver in flashlights with 22mm diameter driver cavities - just make sure that the shelf and retaining ring fit the driver and don't hit other components. Afterall, the Lume1-fw3x was designed specifically for FW3X flashlights only. thefreeman is right that you can solder the e-switch wire where the red arrow is drawn in the diagram. Perhaps more designs will be made for other flashlights in the future.

As for springs, yes, since Neal / Lumintop is fabricating the drivers, they will be able to use the same spring as the stock FW3A driver. It'll be nice if they sold the springs separately too, since I think they're the perfect size and profile for many small drivers. Individual drivers sold by Neal will of course come with a spring cool

Finally for AUX LED boards, I'm working with Neal to find the best way to get these produced. Most likely it'll be the RGB AUX boards - for the tri-LED boards, different LEDs will require different series resistors, and I'm not sure what the best solution is to sell that since there can be so many variants.

If I may I have one minor comment about your design. I’ve noticed that your pads for pogo key have switched places for mosi and miso against already standardized pattern. Look like you can easy fix this to be in line with other drivers on the market.

I would love to see another version of those efficiency plots done with a triple Nichia/Samsung/Luxeon/SST20. As you know, the single XM-L2 is the worst case for buck-mode efficiency and also and unlikely case for the application. Boost-mode might reach the full 3A @2.7V too?

Thank you, thefreeman and loneoceans, for answering my question. Thumbs Up

Good to know where I can solder the e-switch. Now I am planning some RGB aux triples. That should look awesome.

You know.. I just now noticed that there isn’t a flat notch on this driver to match the FWs driver cavity/ledge. Am I missing something here? Is it not needed? Or perhaps is this a feature that’s not on the copper model that caused a minor oversight in the pcb design?

Thanks all for the feedback! 

Yes the current iteration of the driver PCB is indeed round, because of the specific flashlights I have tested with. You are correct that the aluminium version (not the original ones, but the standard ones) do have a notch. I'm not exactly sure about the newest ones since I don't have them. The copper version, at least the one I have, does not have the notch. I'm working with Neal to determine what the actual cavity specifications are. Regardless, it's an easy adjustment with a little bit of sanding or filing to get it to fit if the specific flashlight cavity in your flashlight does have a notch. Once I get clarification I'll be updating with more details.

Yes the production boards are updated to swap MOSI and MISO, so it'll be the same as existing flashlights!

Is there a chance that some PCBs will have the same layout but bigger diameter (~24-25 mm) to fit 21700 e-swith flashlights?

FW doesn’t use notch anymore but drivers still has it.

Thanks everyone for the great feedback so far, and thanks everyone for your patience.

Just a quick update - the first batch of Lume1-FW3X drivers have been produced. I am arranging to getting some shipped to me so I can validate the build since I have no idea how they turned out yet! 

In addition, a lot of people have asked about Aux boards. Neal has produced some RGB AUX boards. 

https://imgur.com/po5GYL3
Here's a very quick GIF of what Neal sent over. Tweaking of resistor values in progress for LED brightness. I do not know what his plans are for AUX boards but I see no reason why they cannot be offered for sale as well. Please excuse the odd effects from video to gif conversion.

More to come soon!

I don’t think it’s a big deal. If you are able to swap a driver, you can file a tiny flat spot. It seems most drivers need some cleaning/fitting anyhow.

I passed both designs to Neal. However, it's up to his team to decide which to offer for sale. You can imagine how having custom LED colours for everyone may become complicated quickly, but if you're interested, be sure to let him know! Alternatively, you can make your own as well from the OSHpark files posted. Cheers

loneoceans, the GB driver still has a sense resistor that adds significant resistance to turbo, right?
Also, is the schematic available anywhere?

Also I have same question for months and doesn’t received any clear answer it will “lume 1” will be OSHW licensed or only will be open source firmware?

The schematic and source files will be up on my github and webpage as soon as I get them together.  The production driver has a sense resistor that adds resistance to Turbo. Based on some prototypes I've built in real-world usage, the total actual resistance in the power path including wire resistance, contact resistance, battery internal resistance, and other parasitics, the total resistance that the Lume1 driver provides to the LED is just a few mR higher in best case scenarios compared to the stock driver, or sometimes matches it.

The FET used in the Lume1 driver has a higher voltage gate drive as well for lower R_ds_on. This means that for the roughly ~30-ish seconds the driver is in turbo, the maximum brightness is either almost the same as the stock driver in most use cases, or slightly lower when used with a very high discharge, warm cell (e.g. VTC5A or 20S), with spring bypasses. So overall, yes the sense resistor does add some resistance in general; its up to you to decide if it's an acceptable trade-off between the added features, or not. smile

Hello all, 

Thanks so much for your patience! The Lume1 driver timeline was delayed a little more than I was hoping due to shipping delays across the world due to the current situation. However, I'm glad to say that thanks to Neal and his team at Nealgadgets, they were able to produce the first few factory prototype Lume1 drivers for production. I just received them in the mail.

In the following pictures, I'm comparing them with my copper FW3C and Lume1 driver.

 

Both flashlights with Lume1 driver, with my build on the left, and the prototype directly from Nealsgadgets. We have here the standard FW3A with XPL-HI LEDs. 

 

Neal also provided the RGB AUX LED board. The tri-LED board provides so many options that it may be difficult for Neal to customize individually... but I'm not sure yet. If you're interested, do drop a message to Neal about it. 

 

In this prototype build, I'm please to say that all functions checks out Ok!

As we know, R+G+B = white

And here's how the RGB AUX LED board looks like. Neal originally populated the RGB resistors to be too low a value and they were extremely bright! I have revised the resistor values for Neal to take note of in future builds. 

 

And here's the raw Lume1 driver from Neal. 

 

Overall I was pretty happy with how the functionality turned out - all functions were verified, and it's pretty cool to see the FW3A with a factory-made Lume1 driver!

There were some issues in the prototype that I need to sort out, though most of them are cosmetic. For example, while electrically the PCB is good, I wasn't pleased with the overall finish of the PCB soldermask, HASL, and silkscreen. Likewise, there were some component swaps that Neal's team made to reduce BOM cost, the most obvious is the sense resistor (confusingly a slightly higher value was used). I'm in the process of discussing these with Neal so hopefully we can get an excellent product to everyone. I'm suggesting to Neal to have a matte black soldermask with ENIG gold finish, or at least the same as the stock driver (purple with ENIG) - if you have other opinions please drop a message to Neal as well. 

 

At the moment, I'm not exactly sure what Neal's plans are but it appears he plans to release the Lume1 driver in some special edition FW3 flashlights first, and then proceed with a driver sale. I've communicated to Neal about the community's interest in individual driver sales, especially to those who signed up on the original GB list! 

Thanks and stay safe everyone!

Please don’t make black soldermask on PCB driver board. Any other color different from standart green will be fine. If you need to trace track on PCB for repair black traces are difficult to see. Original purple colour or red will be good choise. For AUX board I think black will be fine.
