Technical components for the flashlight

Not sure if this is going in the direction you are looking for, but to some of your questions:

• Buck-boost is a driver that I can connect through some device, for example, to my computer and adjust to the brightness modes I need (50 lm, 300 lm, 600 lm, 1200 lm, strobe light by quickly double-clicking on a button). I need the Buck-boost driver because I need the brightness to be constant and not decrease all the time the battery is running.

You could start by looking at the lume1 driver, created by @loneoceans.

Here’s a datasheet: click

You’ll be lucky to find a pre-built lume1 driver for sale anywhere these days, so you’d probably have to have to put it together yourself:

• A device (if there is one) that I can connect to my computer to configure the driver to the modes I need.

The driver is programmable via flashing pads on the underside of the board. You can use Hank Wang’s flashing kit with your computer or an Android phone to flash/re-flash the firmware. This can be purchased here: click.

However, take note of the need to swap around the MOSI and MISO pins - see “Flashing Firmware” here: click

The lume1 driver is supported by Anduril 2 firmware. Anduril 2 is open source, so with sufficient programming skill, you can re-configure it or modify it to achieve the modes you are looking for.

The code repository for Anduril 2 is here: click

• Powered by a 21700 5000 mAh battery.

The lume1 is designed physically to fit in an 18650 FW3A host with a tail-switch. However, since you are designing your host from scratch, you may be able to design it in such a way that a 21700 can be used. Otherwise you may need to change the design of the lume1 board to fit the different dimensions.
