My son is experimenting with light painting in photography so I want to make a few led based light paint sticks. Planning to go from simple single color led to perhaps one driving one or more WS2812 led pixels from a arduino…
Thinking I could use some 3/4" pvc conduit as a case that would work well as a holder. Could use a pair of AA cells to get 3.0 volts but a 18650 would give me 3.7 volts with a much higher capacity. I’ll use a boost convertor to get it up to 5.0 volts or try running it at 3.7… Plus I can add a charger to avoid replacing batteries…
Anyone know of a decent local source for 18650 cells?
I thought about using the Nokia batts that we have but attaching leads to them is a bit of a pain and the form factor isn’t ideal for what I want…
I bought a bunch of 18650 cells from @Gonazar that I can’t use as the C rating was too low for my eBike battery build. These would be fine for your project. $5 each and from a reputable supplier.
