I've been wondering how to power Arduino projects inside Nerf blasters.
I'd like to find something that young / beginner modders can pick up easily.
Let's take a case study. Adding LED lighting, say an LED strip chase sequence along the top of the blaster, which happens on trigger pull.
There are two types of blasters:
electronic - typically featuring 2x motorised flywheels - these take alkaline batteries totalling a nominal 6v or 9v (e.g. 4 or 6 standard alkaline cells).
"springers" whichare mechanical and have no on board power.
Many of my own "elecronic" builds ditch the alkalines for a suitably sized LiPo (with alarm) for motors etc and a buck converter / BEC to handle the arduino and everything else.
Similarly, if I were to put lighting / sound on a "springer" I'd probably use 2s lipo + BEC combo.
I feel that is a bit much to expect entry level modders to deal with LiPos.
Is there any way I am missing for powering such things? Multiple Alkalines or a 9v and using the 5v output seem to be so limited.
