Intro: Magnetic Battery Pack
I don't know about you guys...and gals. But when creative genius strikes I am very rarely in the lab. And as for me, when I am overcome with a flash of inspiration I have to do something about it RIGHT NOW!!!
As a result I keep a lot of tools in my car. But I cant keep a ton of parts on hand so I improvise.
For this project (Hacker Hack) I will be demonstrating my super simple method of attaching batteries to a prototype.
What you will need:
A pack of small Neodymium magnets (10 for $2 at harbor freight)
Two pieces of stranded wire. (solid core works but isn't as flexible.)
A couple of batteries (whatever your project calls for)
a soldering iron
let's get started (like you haven't already figured out how this is going to work)
Step 1: Let Do the Hard Part First.
pretty simple just solder a magnet to each lead. Make sure you use one red and one black (just makes things easier.)
WORD OF WARNING! your soldering iron is made of steel. the magnet will stick to it and freak you out while you scramble to find your pliers. just sayin.
and yes you could probably just use tape but honestly.......how lazy are you?
Step 2: Hook It Up.
next just place a magnet between your batteries (positive to negative...you know who you are.) the neodymium magnets are super strong and will hold them together. and yes they are conductive with no noticeable resistance
Step 3: Seriously That's It.. There Is No More...stop Reading
super simple but a lifesaver when you don't have a battery pack on hand.
