Hope everyone has been well and staying healthy.
There have been some delays recently due to other commitments, but here are some news updates to the lume1 project.
Here's the driver together with the copper FW3C flashlight and tri-RGB Aux Board. LEDs are Nichia 219B 4500k 9080.
I've since received a Rev B PCB of the board and was able to put it together. Rev B improves on some of the layout, silkscreen, and fixes the reverse current flow issue during boost operation. Anduril functionality has also been verified, and a driver efficiency characterization was also completed.
With the suggestion from Agro, I was able to find suitable small RGB LEDs and have designed a board for them. They're based on the verified board outline as the tri-LED board which I'm currently using, so it'll fit. Boards have arrived but LEDs have not yet.
Finally, I'd like to thank everyone for their support. I've been writing up a more detailed 'datasheet' for the lume1 FW3x driver.
To wit, I am planning a one-time group order of assembled and programmed drivers. The only issue I have right now is that I haven't yet found the source of the same spring which Lumintop uses, so likely the driver will be built fully assembled, and the user needs to solder their own spring and LED wires on, which I think should be OK.
I'll be finalizing the production design soon but it'll likely be very similar to the Rev B design with maybe some changes in silkscreen and cosmetics and no electrical changes.
Will also be creating a Google Doc as suggested to start an interest list very soon, where I will be gauging interest based on estimated cost, as well as other options such as PCB colour and so on, so please look out for it! It is most likely the PCB soldermask will be a more conventional one, such as green, or red, or blue or black etc.
Likely we'll need at least 50 boards at the very minimum for a group order to be economically feasible.
Thanks everyone.
