Hey guys... niece is wanting to build a shadow box with mini light sabers in it.
I got the STL files for Vader/Luke/Obi/Yoda's sabers and got acrylic rods we plan to "frost" so the light shows up. Just a small project.
I am gambling with AliExpress, fingers cross, not had much luck with them. Ordered from places with a 4 week ETA instead of an 8 week. Found 1 seller with pre-wired LEDs, and because of size, grabbed the 3mm ones (blue, red, green). Says 5-12v. I also bought a Type-C usb 5v1A charging module with safety for Lithium batteries. I also have a small switch, and a buck-converter that I can use from another order. Tonne of resistors, I think all 1/4w.
Plan is to make a box/frame for the wall with no wires that can be recharged.
I was looking at something like THIS BATTERY, 3.7v 1000mah, small and rechargeable, cheap and fast shipping. But, 3.7v not 5-12v.
Would I be better off with something bigger? or will the buck-converter set at 5-12v work or do I need this DC-DC BOOSTER? How long would 4 LED's last off that battery? Should I grab other lights? (was trying to find 3v ones pre-wired but didn't see any with 4 week ETA's cheap).
I "think" the plan is to wire the 4x3mm LEDS in parallel, run the wires to the booster, booster to the type-c charger, from the charger to the 3.7v 1000mah battery.
The switch I have on hand, I guess between lights and booster?
