For my project I was planning to use 2 power sources - one for my Domino and another to drive the DC motor board sold through here.
Initially they will be based on cells that I claimed from a cordless drill batter pack for which the drill broke. It had 15 C sized 1.2v 1200 maH batteries to make up the 18v. Eventually I’ll replace them with Lipo/Life power packs for lower weight, but for now I’m using what I’ve got on had (plus I have a 2nd extra pack for even more cells ;))
My plan was to use:
- 5 connected to the barrel plug - since they can put out up to 1.5v each, this is to be safe (and not needing an external regulator).
- 6, to start with, for the motor controller board & the 2 brushed motors
In another thread I saw this:
My questions:
-
So does this mean I need connect the “black” wires together from the 2 different packs?
-
A quick sanity check - Does my power solution look ok? I realize it’s not the optimal or most efficient way to go about this, but it’s baby steps for me.
