Do-It-Yourself Mjölnir: Thor’s Hammer Plus a Tesla Coil Equals 80,000 Volts of Fun

Thor's Hammer

Without his hammer, Thor is pretty much just an average guy. His Mjölnir gives him power and it seems like he’s just lost without it. If you thirst for power like that of Thor’s, then here’s a bit of good news: you can now make your own Mjölnir. You won’t suddenly develop god-like good looks or grow hulking muscles, but you will have a hammer that’s capable of emitting 80,000 volts of electricity at your disposal.

Behind the DIY Mjölnir are Caleb Kraft from Hackaday and Tesla coil expert Staci Elaan. The hammer was basically constructed by embedding a Tesla coil into a foam pop. At the push of a button, 80,000 volts of electricity are emitted and arc from the top of the hammer.

Tesla CEO Offers Damning Refutal To NYT’s Negative Model S Review

10JPTESL1-articleLarge-v2

On February 8th, the New York Time’s Josh Broder released a scathing review of the Tesla Model S, claiming it was unfit for cold weather driving. The problem was, according to Elon Musk, Tesla’s CEO, there were factual inaccuracies in the piece. Matter of fact, according to him, the review “was fake” and he would produce some hard data to back that up. Yesterday, he did, and it’s quite shocking. It turns out Broder did a number of things to, at least apparently, purposely sabotage the test. Here are just a few:

    The car never actually ran out of battery, even as the flatbed truck was being called.
    On the final leg of Broder’s trip, he disconnected the charger with a range of 32 miles on the dash, when that leg of the trip was going to be 62 miles. “He did so expressly against the advice of Tesla personnel and in obvious violation of common sense.”
    On that last leg, Broder drove right past a charging station, even as alarms on the dash were telling him that he was low on charge.
    Perhaps most damning of all, in one of the legs of the trip, Broder drove around in circles in a tiny parking lot for over half a mile, attempting to drain the battery fully, which was displaying “0 miles remaining”. He didn’t succeed that time, though apparently that motivated him to try harder next time.

There are quite a few other things, and you should definitely head over to the Tesla link below for more details. It’s sad to see media outlets trying to destroy the reputation of what could very well be the future of transportation. In the end, hard data speaks louder than everything, and we hope Tesla succeeds in reversing whatever damage the NYT might have done.

House Of The Rising Sun Played On A Pair Of Tesla Coils

I’m home, bored on a Saturday evening, so here’s an oldie but goodie for those of you doing the same and stumbling upon a rare weekend OhGizmo! post in your Interweb meanderings. It’s The Animals’ House Of The Rising Sun played on a pair of Tesla coils. Yes, there’s sparks galore and yes it’s as awesome as it sounds.

As the YouTube comment says: “Dude. Science and sh#t.”

Enjoy.

Tesla Model S Does Quarter Mile In The Twelves

We knew the Tesla Model S was fast, but when we read that it was doing the quarter mile consistently in the 12s. region, we were blown away. “This past weekend at the Palm Beach International Raceway in Florida, the National Electric Drag Racing Association awarded the Tesla Model S its stamp of officiation for being “the quickest production vehicle” in quarter mile tests.” It ran the distance in 12.371 at 110.84mph, a number that is very impressive for very large and very fast combustion cars, let alone electric ones. It’s even more impressive considering the Model S is rated at only 416HP and weighs in at a hefty 4,700 lbs. Clearly the electric power delivery and curve, and instantaneous torque, all combined with the lack of gear changes (it uses a single-speed gear-reduction transmission) produce the kind of thrust that is hard to match without consuming ridiculous amounts of gasoline. And don’t forget that despite the blistering acceleration, the Model S is capable of traveling up to 350 miles on a charge, although of course this is with more sedate driving.

This car is still a luxury item, and it’s not even one that will really save you money on the long run. It is however electric, and on par with luxury sedans in its class, cost-wise. So all else being equal, if you’re really hankering for a greener ride but are worried about performance issues, the Tesla Model S won’t let you down.

oneTesla: Fancy Building Your Very Own DIY Singing Tesla Coil?

OneTesla

If you paid attention in all your science classes, then you know very well who Nikola Tesla is. If you didn’t but paid attention to the Oatmeal, then you’ll probably agree that Tesla was the greatest geek who ever lived. Aside from his numerous inventions in numerous fields, most of which he didn’t get credit for, he has also imparted us with the gift of electric music.

Okay, so he probably didn’t intend for his coil to be used to produce music, but apparently, it can be used to do just that and the people behind the oneTesla want you to do it. Only those who can actually build one, however, will be able to enjoy the fruits (or is it songs?) from their labor, because they’ll have to build their own Tesla coil from the provided parts. And from the looks of it, it’s not going to be easy.
