Thanks for the reminder; done!
Cool idea! :+1:
Subscribed to see how this proceeds.
Looks cool!
Sounds like you have a plan.
Maybe you could fit in one of those little usb chargers as well?
Ok, I’m back in my box.
subscribed because its a lantern build!
I like the idea (a TP4056?). I dunno if it’ll fit well into the design, but I’ll definitely keep it in mind if it looks like it’ll fit!
Nice idea, looking forward to watching the progress.
You are the man, to do this that is.
Do many LEDs in parallel, so they all get a smaller bit of current, that way you get much higher lumens/W and you can get longer runtime
Behold, the flip-lantern!
Ingenious
Love the tilt idea, though some kind of lockout would be useful.

Good luck!
Have any of you tried PCBWay or AllPCB for your PCBs? I’m leaning towards PCBWay for this project. I always use Oshpark but I’m looking to get ones with white solder mask. They’re both in China, but seem to have good prices, lots of options, and pretty quick turn around time.
Cant help you there. I’ve only used Oshpark.
Ok, I’m still learning about proper driver designs, so I’m going to throw my schematic and PCB out here for critique before I order it. The PCB has been uploaded to Oshpark, but I will likely be using a different service (see above).

Another note… I decided to simplify a bit and spec out a Current Regulating Diode (1ma version) in place of the LDO+resistor. I’ve never seen one used but they appear pretty basic.
Oh, another thing… While this is one board, I’m basically designing it as if they were two separate ones, the circuitry is independent of each other. One side will be used as the main board of the lantern while the other will be a slave board.
Why is there a ring around the center pad? What purpose does it serve?
Looking at your schematic. Can you describe to me in words how you expect it to function? I’m having a hard time trying to understand it. :person_facepalming:
EDIT: In particular, the switching doesn’t make sense to me. I understand the slide switch disconnects the ground and turns the light off, but what is the tilt switch supposed to accomplish?
Hey David!
OK, I get it now, the two power deliveries are wired parallel to the LEDs. Either just the 1mA source or that plus the 7135 will be on. :+1:
