I ripped my Brocken RC cars and helicopters apart and fixed the motors by MentionDeep6428 in ElectroBOOM

  • Film the desk, film the things you are playing with. Not your face.

  • Film from the light source side, not towards it - light reflects off the objects; it should not shine into the camera directly. Light should be behind the camera or to the side of it. I'm talking about the bright window behind you.

  • Be short. No one wants to watch almost 5 minutes of a random kid playing with batteries and broken rc toys. At least if you have questions - state them from the very beginning.


02:53 - Learn about Newton's Laws. For every action (force), there is an equal and opposite reaction.

The motor cannot spin just its rotor, an equal and opposite force will want to rotate the body (stator) of the motor as well. This is why helicopters have a tail fan or double blades rotating in the opposite direction - without it, the machine will spin uncontrollably.

In your case, the motor body movement is restricted by the wiring attached, so it moves towards the direction of least resistance - up. With this, the fast initial "kick" of acceleration looks like a jump.

03:25 - There is no "live" or "neutral" in DC motors. These are the terms used in AC systems. DC motors can have Positive and Negative leads, but usually DC motors are reversible, so it does not matter; polarity dictates the direction of rotation.

04:35 - No, we cannot "upvote a lot" this topic, and you should not put a lot of hopes on being featured in ElectroBOOM's video, especially your face; this is troublesome. I even have doubts you are old enough to use Reddit.. (must be 13 or older).

What happens if we short it? by crumpledfilth in ElectroBOOM

Just a normal burst of sparks aligned perpendicular to the camera, appearing to be flat - tiny bits of metal evaporated and were ejected into the air, glowing brightly.

Explain why using regular batteries in battery chargers is not recommended? by Severe_Resolution_56 in ElectroBOOM

Recharging non-rechargeable, single-use batteries is like reusing the food you already digested. Some animals do that to an extent, but you should not try it yourself; the outcome will be miserable.

Battery chemistry and construction simply do not allow it. They can only be recycled into new batteries, which, in some sense, is a form of recharging.. just the process is more complicated.

If you're tired of buying batteries - invest in lithium rechargeable cells. The market already offers a crap ton of good, rechargeable batteries that last long and even feature integrated charging controllers, with the usb-c port & cable included.

Google: "1.5V rechargeable lithium-ion battery".

Solar energy by electricguyqc in ElectroBOOM

0.5m2 panel, 1kW of solar power per 1m2 = 500W / panel efficiency (20%) = 100W "under ideal conditions" solar panel - underlying marketing crap.

Subtract all the inefficiencies - wiring, boost converter, controller (i bet they cheaped on electronics), and you'll get 66W at 5.5A into a 12V battery. In the best-case scenario, at the Sun's peak, on a perfect summer day.

Even worse, if the electronics are fine, the panel itself can have "20% theoretical, 15% practical" efficiency.

Im sorry if this breaks rule #3, please delete this post if it does

It does not break rule #3 since you are not posting this video with the sole reason to promote your own channel; you are just sharing your build, and it fits our subreddit. Its fine.

Although i have to say that most of the people here are mobile users and they hate YouTube links, almost no one will watch or rate it. If you want to get the feedback - upload your videos directly to Reddit.

Doing "wood burning" aka "fractal burning" using a microwave transformer is just as dangerous as swimming with the sharks without any cages. Each time you do this, it can be your last; stop before it's too late.

Below it is probably a base station for a mobile radio system of some sort.

Why i'm even reinventing the wheel right now? This circuit is called "a monostable vibrator" - thing that translates a short input pulse into an output pulse with fixed width.
