I’m 3D printing a mood light with a 1-3W COB LED. I want to have different light effects available (pulsing, candle, etc). Rather than rigging a microcontroller with a MOSFET and writing code, isn’t it possible to use flashlight hardware that runs Anduril? I’m extremely happy with my Anduril flashlights, and it would be really easy to implement and operate, but have no idea where to start with the hardware. What driver is available off the shelf and would suit me? Unlike a flashlight, I’m not tightly restrained by the available space.
The light would run off USB-C with buttons to operate it. I’m comfortable with power supplies, uploading firmware, etc. Just a mild dislike for programming and I’m not fond of reinventing the wheel.
This kind of thing is outside my knowledge but I’m interested in learning more.
Will this be mains powered or battery powered? If the former, you’ll need to convert to 3v DC and possibly do something to control the current. It might be easiest to start with a wall plug made for USB but I think you might still need to address the voltage.
If battery powered, I’d say use something like the Sofirn SC31 pro driver (search for Sofirn drivers on Aliexpress). It has Anduril 2, aUSB C charging circuit, and a lighted e switch.
Do you want to use Anduril’s aux light feature? If so, I’d suggest a driver with aux wires or pads. I don’t know offhand which have those but I don’t think the SC31 Pro does. Wurkkos TS11 does (along with USB C) but not sure if that driver is available by itself.
Lastly, you said operated by buttons. Anduril does everything via a single e switch. Did you have something else in mind other than a single button?

Jlhawaii sells emisar/noctigon drivers that will support aux.
I would power it from a wall outlet. Something USB-C and some decoy PCB or so, to set the right voltage and current.
What exactly is the aux light?
A for buttons: I guess Anduril is single button operation, yeah. I would still like a separate button to toggle the light on or off.
Looks like Sofirn is selling their bare driver boards, https://www.aliexpress.com/item/32859323105.html . no other info provided. Some of those run Anduril. I can’t really find a list of driver boards that are Anduril compatible.
Ok, that establishes you don’t need a driver with USB charging and you need, like you said, some components to give the driver the correct voltage and current.
Although, does it need to be USB input? I searched for 4V power supplies and found something like this:
Mpkke 4V 2A AC/DC Power Supply Replacement Adapter with 1.7mm x 3.9mm Tip Center + Amazon.com
With that presumably you could cut off the plug, check polarity, and solder it right to your driver (or first a master power switch). This seems like the easiest approach rather than using USB and needing to buck it down from 5V.
Edit: the 2A output of that power supply may not be high enough for your purpose. What kind of lamp are you trying to make? E.g. a desk lamp, reading lamp, etc.
yeah, feeding the driver is no issue. the LED is only 1-3W.
If you insert a master on-off switch then don’t you lose the ability to have the light turn on at the last used level? That would bother me.
I have built a few table lights and have always incorporated one or more cells as sometimes it may be handy to be cordless and portable. There’s always been a usb charger builtin as well.
yeah, it’s something to think about. trying to put the puzzle pieces together. I figure Anduril can’t save the last setting to the permanent memory?
you’re probably right about including a battery after all, it makes things easier and adds a bit of versatility.
