Simple But Nerdy

If you have heard songs by Buckethead such as "Jordan", or maybe are a fan of Tom Morello's guitar , then I guess you already know what a killswitch is... A "Killswitch" is just a switch responsible for muting or in a way 'killing' the guitar'sound temporarily. Why would you wanna do that you ask??? Well, I guess you will have to listen to Buckethead or Tom Morello's guitar to find that out. Buckethead's song called Jordan using a killswitch: https://www.youtube.com/watch?v=OTcg9JybEp8 Tom Morello demostrating the killswitch: https://www.youtube.com/watch?v=cxeBzXVm67o So how does a killswitch work you ask?? It works in one of two ways. The first way uses a guitar with two pickups having a different volume knob for each. Turn one knob to zero and the other to 10 and start toggling the pickup selector switch quickly. Behold!! You have a killswitch!!!.... Though, this method has a few problems. Firstly, pickup selector swit...

Oh!! Back for more nerdy stuff???? So, in my previous post I explained how to levitate a particle using sound or "Acoustics" ,because it sounds way cooler..... Now while my explanation was really basic you now know the foundation of the workings of this device..(kinda..) ...... 😝😝😝😝😝😝😝😝😝😝 Let me get to the point where I explain how I built it...... This is the basic block diagram of my levitator..... TRANSDUCERS: A transducer is just a fancy word for speakers and I admit it sounds really nerdy so I'll use that.... For transducers I needed ultrasonic transducers (so we don't hear the sound) and the best source for that were these ultrasonic distance sensors. These, firstly, are really easy to get hold of. Secondly, are very cheap (about Rs.80 a piece), so I bought 10 of these. Now, as in the image there are 2 metal cylindrical thingys that look like Wall-E's eyes.... under each eye there are labels 'T' and 'R'. ...

About a year ago I came across this video talking about the concept of acoustic levitation and the fact that you can use sound to move objects in mid air. While I was really intrigued I also felt that having such a setup at home would either be really tough to build or would be really expensive. Soon after, I came across a video about a team of electronics and computer science engineers at Bristol University who actually came up with a method to make these levitators really cheap and were even selling and promoting kits to school students to do the same. This made me confident that I might be able to pull it off too.... 😝😝😝😝😝😝😝😝😝 Being an engineering student I was told to make a project under something called a "Non-Teaching Credit Course". So I chose this as my project for submission. SO HOW THE HELL DOES ACOUSTIC LEVITATION WORK??? A short answer of this question could be "Standing Waves", but that doesn't really explain anything, so let me t...
