I’m rather new to modding flashlights and doing DIY builds but I’m excited to start learning. I may have missed this on the forum but all I can find for “DIY” guides are how to flash Attiny chips or match together parts to build / mod a flashlight. I really want something where I can solder the pieces on myself to a partially blank PCB and actually build a flashlight by hand.
These are completely blank PCB with only the traces ready for you to mount the components on. I can’t solder the extremely small pieces.
Ideally I’m looking for open source driver PCB eagle or easyeda files that I can have made at JLCPCB with their SMT service putting the tiny parts on and myself hand soldering the larger parts.
If I can figure this out and get all the components cheap enough I want to host flashlight building classes locally for kids and families (along with other electronics).
Most of the stuff that’s come from BLF members is usually done at Oshpark. Generally using eagle I never upload the gerber files, I just click the Oshpark icon and click upload. If you are needing the gerber files then you may have to take a design, copying and creating it yourself in eagle, unless someone knows how to get the downloadable files from Oshpark to eagle.
where they walk through the different components of the LED driver. I tried my best to recreate the PCB based on their schematic but I don’ think I did it right because I am outside of my depth on this.
Specifically having issues with the mosfet not looking right but that’s the only one I could find in EasyEDA that seemed like a part match? Any guidance would be much appreciated.
I think pin 6 PB1 should be the only trace connected to the fet pin gate. I think the author on that site forgot to use a jump over instead of what looks like a connection.
I’m no expert but usually the gate just receives the signal from the mcu to either turn on or off.
As for the library files for components I use a program called library loader that finds footprints and symbols for you.
A lot of them can be found on the web from a google search but it usually takes a little extra time.

You can see in the pic at pin 6 it runs straight to the gate of the fet.
