How to Make a Strobe Light

[@โชคดี-ฌ4ง]

Loved the video, specially the goofy parts and the learning of course, thanks!

[@BlueprintScience]

Goofy learning is the best learning! Thanks, man. I'm glad to hear that you enjoyed it

[@mattmoreira210]

Hello there! Great vid! Cheers and happy new year! P.S.: 2:00 that bulb is a Xenon, much like the ones found inside photographic cameras. That thin wire running across and around looks like a filament of sorts, but - trust me - it is not! It is a cathode, and helps ionize the gas inside the bulb, so that the discharge between anode and cathode can occur with a lower voltage (500v or thereabouts).

Great job brother I've been trying to make an AC version Strobe light That runs off a 2 cycle Lighting coil

[@naitikshailendrakumaryadav2824]

Hello sir, how r u? Nice video, recently i have started watching your video. It is full of education and a new way of learning.

[@zefdin101]

Great job and great chip the ole 555 timer! Loved the vid!

[@cockspurts2925]

great informative video. I've had an idea for years and this put things into perspective.

[@brendanmurray8498]

Hi Blueprint, great videos thanks. I just wanted to comment on the MOSFET circuit. If this was a BJT you are correct that there needs to be a current limiting resistor between the 555 and the base. However the gate of a MOSFET is almost infinite resistance so you actually need a pull -down resistor. In this case, the 555 output goes directly to the MOSFET gate and the resistor (something around 10K) would connect to ground. Hope this is helpful, have a great day.

[@nigel-matthews]

That was helpful to me - thanks!

[@englishrupe01]

Thanks.

[@Dexter-dz4bp]

Ur vids r the best bro keep it up🤟🤟

[@Xonk61]

when you refer to the old style strobe tube, and mentioned it as being incandescent, I figured you were speaking of a bulb with a filament, but the Xenon tubes I've used in strobes use an excited gas to flash. I guess that's what you are talking about, right?

[@BlueprintScience]

The one I had has a filament much like a camera flash

[@Xonk61]

it wouldn't need high voltage to operate, would it?

[@BlueprintScience]

The one I took apart had a peak voltage of 50Vdc and the LED chip that I used required about 24Vdc. I've seen some LED arrays (in series) that require about 100Vdc. It really depends on the type of light source.

[@Xonk61]

I'll bet that made for a blinding flash!

[@jp040759]

@@BlueprintScience Camera flashes and real strobes use a Xenon flash tube. There is no filament in them. What you see in some is they have a trigger wire wrapped around the flash tube which is the high voltage trigger for the tube that ionizes the gas inside to conduct and produce the main flash from a capacitor charged to 300 volts or more. Incandescent bulbs filaments warm up way toooo slow to be used for camera strobes. The extremely short burst of light from a Xenon tube is what freezes motion in photography or when using them in a stroboscopic applications.

HI. very good explanation I like how you explain things. Very good learning experience am going to replicate this to mount it on a DJI DRONE

[@BlueprintScience]

Should you have any questions, I am available here to answer them.

[@HornetKingOfficial]

Great videos! I am binge watching and have enjoyed all your videos so far! Keep on sciencing, brother!

[@BlueprintScience]

I'm glad you are enjoying yourself You even suffered through that audio from my early videos! That's commitment!

[@HornetKingOfficial]

Blueprint, takes more than than that to knock me down! Lol. Keep putting out content, brother!

[@willhay3108]

A assume the gaffs were for learning value alone?

[@ele4853]

Nice job. Thanks. Would it work with a 12VDC battery? if not what would be the changes to make it work? thanks in advance.

[@alannorthcarolina1776]

Ok…so…how do we package it up for mobile use? Ac to dc and signal/waveform generation.

[@kevyelyod1211]

All fun and games until someone has a seizure 😀

[@RifaiAL]

Excellent effort, bro. Can you provide an ideal circuit diagram and Parts list to make a frequency adjustable water levitation strobe light?

[@BlueprintScience]

Absolutely. In the video I make an astable circuit (time on > 50%), but for the water levitating experiment you want to use a quick pulse. You can use the monostable circuit (time on < 50%) on page 10 of the 555 data sheet: www.ti.com/lit/ds/symlink/ne555.pdf I also recall that ElectroBoom channel did what you're trying to do. Here's how he did it: www.electroboom.com/?p=268 Let me know how it goes

[@appdataprozent2537]

duude I attend a technical school and if we destroy a single component, the teachers usually freak out ... a group of students once managed to place a tiny light bulb beneath their oscilloscope and the plastic started to melt from the heat... the result was a very bad mark on their project 😂😅

[@BlueprintScience]

I'm sure you can imagine my instructors are very... concerned when I get to work. I have the uncanny ability to make things explode - even when i'm not trying ;)

[@appdataprozent2537]

Blueprint Exploding things are more exciting anyways 🤔 by the way from where are you? I'm from Austria 😏 pretty small and 'mountain-y' country

[@BlueprintScience]

There's only one country where you can blow things up in you back yard and nobody cares: Good 'ol US of A. Michigan, specifically.

[@uK8cvPAq]

My instructors were like that too, they were even wary of letting people use polarized capacitors after a few went pop in someone's face.

[@gossumx]

This was so good. Being the snobbish, heavy (youtube) user that I am, I almost left for video quality. But the content and teaching style is gold. Subscribed.

[@BlueprintScience]

Thanks, I have since acquired a better camera and upgraded my videography skill tree

[@hermannpaschulke1583]

Nice video

[@sambit0000]

Hello sir can you give me the circuit diagram

[@rossadew4033]

Too often I loose focus and just wonder off when all the dry technical talk starts (1:30) Captions or even on-screen foot notes helps our monkey brain focus a lot better and makes it easier to learn new stuff when explaining something technical.

[@BlueprintScience]

Thanks for the feedback. I'll try to make sure that I CC all of my latest stuff. Those auto-generated CC don't work very well.

[@rossadew4033]

sometimes I leave comments like this more as a footnote for me than as a critique... so grateful for any video with interesting content and that there are YT channels like yours

[@jonfs2000]

Great video! Thanks. One suggestion, audio/speech level.

[@edgardodayrit5536]

what you you do is signal light...and not a strobe light.

[@Elnufo]

50% duty cycle does not get you a strobe, just a blinking light. For an adequate Strobe Effect, you need to make the "on" time way shorter than the "off" time. Add a duty cycle adjustment please.

[@mabutingtao2222]

Awesome!

[@phonotical]

When is next video

[@BlueprintScience]

I don't have a date in mind. When it's done. This video will need a little longer... You'll see why.

[@phonotical]

@@BlueprintScience sounds like a time machine

[@charissefisher4944]

You are adorable!

[@kmanw7841]

What is its maximum frequency?

[@BlueprintScience]

That depends on what values you choose. If you go over 30Hz, you will no longer see and flash due to "persistence of light" effects. However, you can theoretically go higher. A 555 timer maxes out around 1MHz (10^6 cycles per second), although realistically, that number is more like 500 kHz. If you were looking to make something like a Zoetrope or Stroboscope, a 555 is your most stable option. Here is the 555 datasheet: www.ti.com/lit/ds/symlink/ne555.pdf. The circuit I used can be found on page 11.

[@kmanw7841]

Thankyou very much im trying to make a stroboscope with adjustable frequency from 50 to 60hz

[@majesticacrid724]

American electroboom

[@SianaGearz]

Is that a... random-brand VC99? It's self-rated and far from a safe design, you're well advised to stay far, far away from powered-on mains with that.

[@SianaGearz]

Wait, how exactly DID you rig that capacitor explosion? Can't really imagine that you really went in there shorting things with a probe while everything was still on.

[@BlueprintScience]

Wow. This comment somehow slipped by me for 2 weeks... Anyway, between you and me, I have a 50V 12000uF capacitor sitting off to the side. It's not dangerous to touch the terminals. Tingly though. It's good to make people aware of the dangers without actually being in danger.

[@agussulistyawardana9748]

Um, must run "rrn" too.

[@Pedritox0953]

Fun moment @ 1:05

[@sdriza]

Electroboom said he learned it all from this guy in a recent video.

[@MsCpktnwt]

You are grate

First time I've been compared to a kitchen appliance. Thanks!
