Learn about electronics - without any electricity! Build mechanical circuits with Spintronics. Feel the pull of voltage and see the flow of current. Electronics is abstract, but Spintronics makes circuits tangible, irresistibly touchable, and deeply intuitive

Can we make a mechanical radio and use it like we do electronic radios? Immerse a gearset in a liquid to carry the force via mechanical rather than electronic movement. Would that mean that both electrical and mechanical physics are subject to the same laws of physics. That is anything you could do electronically, you can also do mechanically, and what ever you can do mechanically you can do electronically. Mechanical Calculators and Computers partially prove this, or are evidence in its favor. This would mean any mathematical discrepancy in the laws of electronics and the laws of mechanics would mean that the math isn't describing the reality of physics. They would have to be palindromes of each other. perfectly fitting puzzle pieces, every curve followed.

There is a mechanical transistor that makes mechanical PWM possible and was invented over 23 years ago. It is a clutch that can go from a state of engagement to one of disengagement in a millisecond without loss due to slippage and thus no heat loss. Full engagement and full disengagement occurs with the application and removal of a Control Torque, respectively. And as can be implied, it has an Input, an Output and a Control. The Torque throughput can be many thousand times the Control Torque. This can happen because there is no translation of components to establish a state of engagement or disengagement. only the application (or not) of a Control. It's called The Roller Cascade Clutch and was invented by me.

The concept of a mechanical transistor has a long way to go. The base is not simply switched on by a voltage. To turn a transistor on assuming it's a BJT type, you need a small base current. Mechanically, that would be a very slow moving chain on the base which will allow a fast moving chain from the collector to emitter. Then the speed of the chain at the emitter must be equal to the sum of the chain speeds for both the collector and base. Emitter current = base current + collector current.

Whenever I see so much plastic in one place, I want more than anything to smash all of it with a hammer, a sledge, or some bricks. That oh-so-wonderful crunchy plastic SNAP and the satisfying destruction. You just don't get the same feeling from hitting metal cogs and wheels. Oh. That's right.
All of the science in this video was already done hundreds of years ago. It's just been modernized for the kiddies.

The best circuit to build would be an amplified radiowave transmitter and receiver. It might also be good to get input from a mechanical engineer. Several things were missed that could be talked about. Watts or HP (how much and how fast can work be done) = volts current velocity force. The basic fundamentals of electromagnet and mechanical are the the same and often come together in fluid mechanics.

i know there is some one out there who will be able to run DooM with these things eventually. thinking of it, its fascinating that in a different reality there is not electricity and whatever form of inteligent living beings have come to build microscopic versions of these components to create homologous to today's computers.
reply

This is probably one of the most intuitive ways someone has ever explained circuits and the black magic that is electricity to me, to us all. As someone who works on cars a lot and is very mechanically inclined, this makes a lot more sense to me than the water pipes explanation a lot of people use
reply

I honestly think this is harder to understand than electricity. As a toy it's fantastic. For education, I don't think so. Especially for a kid who doesn't know anything about mechanics and gears and pulleys. Just a bunch of chains circling around at different speeds without any clear purpose.
reply

What are the volts in this case? it's a little confusing because the current is like the chain moving at a constant speed then what are the volts, like in an electrical circuit the voltage is determined by how many electrons you have or the potential of electrons (is a difference.
reply

I dunno being both mechanically and electrically inclined, I find it far far easier to understand the electronic circuits compared to the mechanics emulating electronics. Looking at the mechanics I just keep seeing it as a mechanics, I mean the transistor is just a clutch.
reply

I've been thinking about getting this for my niece and nephew to play with whenever they come over. I bought a set that had the actual components attached to plastic and you'd connect them like Legos. The fact they have a little spice program is pretty cool man.
reply

I think the concept is amazing, but for someone like me, who has little knowledge or talent for either mechanics or electronics, it was not easier to understand, to be honest. However for kids it is safer and the larger scale makes experimenting so much easier
reply

I'm asking a bit much, but if it's fair, could you create a video on how to build a DIY FTA satellite set-top box? The ones available are either too expensive or too cheap and tend to stop working after the warranty period.
reply

Make an oscillator. Ideally, make a synthesizer. ;]
But an RC oscillator should be doable. And also perhaps make an electric motor driver as a form of power supply. This would free up your hands to do other things.

I found it funny how this video got recommended to me right after my electronics exam. Really cool to hear such a good explanation for stuff you crammed into your head for the whole week
reply

Theres an actual research field called Spintronics, which deals with using the (magnetic) Spin degree of freedom of electrons in addition to its charge to realize novel functionalities.
reply

Now make an x86_64 complete processor and run a chat GPT3 on one of these. Ok that would be a lot of gears, especially the ram and harddrive components - but you absolutely could.
reply

This is a horrible idea. It complicates an already confusing idea for someone who doesn't understand the real thing. By adding completely irrelevant and counterintuitive analogy.
reply

Definitely buying this for my kids. They're a few years too young to fully appreciate it just yet, so I guess I'll just have to play with it until they're old enough.
reply

I was following the whole video and understanding everything, but then my mind was blown at the fact that outlets look different in other countries
reply

i love how this is marketed for children and it makes it easier to understand electricity and electric components. and I STILL don't understand it.
reply

Wait wait wait, add more resistors in series and the current drops?
The voltage is what drops, current will always stay the same in series

reply

Can you imagine if semi conductors were never invented computers would be huge and bulky unless we really mastered the art of miniaturization.
reply

11: 46 I thought they are going to use ratchet mechanism. It only spins in one direction and also needs an initial force to move.
reply

Well I want to get a kit but I'd modify mine for basically putting thread on a bobbin for my off-grid sewing machine
reply

with the transistor you basically could build an entire CPU. The important question then is: Does it run Doom?
reply

The fact that the method for creating AC power for a spintronic system is playing DJ on a transistor is comical.
reply

PhD in ee here. I really like this. The inductor is a little weird, but overall this is awesome for kids.
reply

I could see this working as a code loop if complex enough. If so, you could create simple little machines.
reply

I'm going to share this video to the school of my kids.
This makes electricity so easy to understand
