F1 engine playing Happy Birthday

When I was researching about F1 sometime ago, I stumbled upon this amazing video of the lotus team playing happy birthday on a F1 freaking engine!

The way this works is that the sheet music is taken and broken down into frequency and the milliseconds that it lasts for.
And the engine is turned on and off rapidly with different frequency tones to produce the tone i.e
OFF  - f1 Hz - f1 Hz - OFF - f2 Hz - f2 Hz - f2 Hz- OFF …. (entire song)

The dynamic response of the F1 engine to changes in the throttle is what blew my mind. F1 cars are able to pull this off due to the extremely lightweight flywheel/general rotating assembly. 

Imperial march on Floppy drive

Now you can do the same thing with motors as well. The motors can be revved up or down based on the frequency of the input.

Here’s the imperial march played on the floppy drive and Super Mario on the stepper motor:

What you are hearing is the tones made by the motor. 

Notice the slider moving faster for higher frequency

If you are into Arduino and DIY projects you can play around with the ToneMelody package and piezo-buzzer to get a similar response.

Thanks for asking. Have a great day!

One hundred years after Albert Einstein predicted the existence of gravitational waves, they have been detected directly.

In a highly anticipated announcement, physicists with LIGO revealed today, on 11 February, that their twin detectors have heard the gravitational ‘ringing’ produced by the collision of two black holes about 1.3 billion light-years from Earth.

This means we now have a new tool for studying the Universe. For example, waves from the Big Bang would tell us a little more about how the universe formed. read more here

If someone ever tells you strong muscular women didn’t exist in the past, and that every woman was little, tiny and dainty, show them their ignorant ass this post.

This is a mosaic of the south pole of Mars. It’s not quite what the eye would see; what’s shown as red is actually near infrared, invisible to us but easily seen by a camera on a spacecraft. Kilometers-thick water ice covers the pole, capped itself by a layer of carbon dioxide ice a few meters thick. That is mixed with the rusty dust eternally blowing in the Martian winds, creating what looks more like something you’d order at a coffee shop rather than the frigid nether regions of a nearby world.

I need advice to know how to gain atleast 10 lbs. I'm on the wrestling team and my coach wants me to move up a weight class.

I have no idea when you sent this because Tumblr stopped notifying me when I have messages, the icon doesn’t even appear so I’m sorry for the delay.

Gainer shakes, plain and simple. And I don’t mean buying the expensive often nasty tasting pre made gainers but instead making your own. This obviously works best if you are training hard as well. Since you need to gain I would either hold off on cardio or if it is required by your coach than I would try to do a minimal amount.

One simple recipe is (and I am simply copying and pasting from a previous post of mine) find a chocolate milk that has the highest calories, Kemps Swiss Chocolate has 170 calories per 8oz class. Add 12-16oz to a blender, 1-2 scoops of protein (chocolate works best), 1-2 pasteurized eggs, 1 serving of peanut butter, 1-2 servings of old fashioned oats, a banana, throw in some fresh spinach (you cant taste this or the eggs but they give it a creamier texture and add calories protein and other important nutrients). I promise this shake doesn’t taste nearly as bad as you might think it does, it’s actually freakin delicious.

Make one of these and add it in every single day in between a meal. DO NOT substitute a meal for this as it’s purpose is to add a lot more calories for growing.You can even drink half between one meal and the other half later in the day, just refrigerate until its time to drink the rest.

Check out this post as well.

Remember, you have to eat big to get big. Good luck.
