Take a bunch of common parts, and create the hottest set of wheels around.
I got almost everything here for cheap or free, or from a swapmeet.
Say goodbye to making gliding motions in order to skate - now you can stand still and watch the scenery pass you by!

Step 1: Angle Grinder
I got this one at a swapmeet for $9.
Take off the guard plate (if yours has one) with a screwdriver.

Step 2: Power Source
You can run power tools on dc power!
Along those lines, I threw together five 12V batteries. More batteries = more power.
Test to make sure they're all roughly the same voltage, or one will drain the others.
Together, my pack measured 60V.
I crimped the wire connections to make them fast-disconnecting, and less prone to spark or come off. Covering them with tape might have worked just as well.

Step 3: Connect the Grinder to power
Remember to insulate with some electrical tape or something.
Sparks and shorts are exciting, but will burn your carpet, and make your batteries sad.

Step 4: Attach a wire brush
This cost me around $4 at the local hardware store.
Spin it on finger-tight - the angle grinder will self-tighten as it spins.

Step 5: Tape the On Switch "on"
So that when you plug in the angle grinder, it goes. I mean GOES. Full-speed.
It's probably a good idea to put a switch somewhere, so you can turn this beast-machine off.
In this version, I just put trust in my sense of balance and lifted my foot off the ground while flailing to find a power cable to rip out. This clearly stood out as the better of the two options.

Step 6: Make your battery pack portable
I got this bag for free - throw the batteries in anything you can carry whilst 'blading.
I considered making a battery-belt, for more even weight distribution. The bag was definitely less comfortable, so I went with it.
I taped the batteries together before throwing them in the bag, to keep them together and prevent shorts.

Step 8: Attach Skates & Grinder
Duct Tape - $1.
Do whatever to make the grinder attached sturdily to your leg.
Make sure the wheel is spinning in the right direction.

Step 9: Go!
These skates create plumes of concrete dust smoke behind you - awesome!
I wonder if I could win at the Seattle Power Tool Drag Races

did you mean, "a while ago, I bought [something] to change 12v-20v dc to ac.. "?
Your laptop runs on DC, and yeah, converting AC to DC is called inverting.
See this.
Think about it. See why it makes sense?
12v DC to 20v DC as you originally stated it actually is ( in electronic/electrical terminology) a voltage converter.
Inverter -> DC ->AC
Voltage Converter : V ( AC or DC ) to different V ( same AC or DC )
The opposite of an inverter is usually a transformer coupled with a rectifier ( usually a bridge diode one ) to convert the AC to a usable current by the appliance.
You actually might have saved yourself money by getting a voltage converter kit from an electronics store to convert your vehicles unregulated 12VDC supply into a regulated V (whatever your laptop V supply is ( the same as the battery pack in it )) DC, but it would have the drawback of being restricted to powering only devices that operate on the same supply. Whereas your inverter can power many devices.
The main reason we generate AC is to supply power over long distance via power lines 99% of the time it is converted to DC on arrival. So to use a an inverter to convert a DC supply to AC to convert it back to DC over a short distance is redundant. Before you ask it IS possible to power some AC devices
with straight DC (not all) it is dependent on their supply circuitry. Check out the history of AC/DC ( currents not the band (sorry bad pun)).
please dont take any offence at anything I've said but as an electronics/telecommunications technician and electrician with over 15yrs experience I only wanted to correct these point and hopefully point you in the right direction research wise. best wishes.
PS staterisk love the ible.. very creative (like most of yours) remind me of the jefferson's when are we going to see the jet powered skateboard? (oops! shouldn't give away ideas so freely, damn!)
