@ malcolmsaint LOLZ, Im here on my iPod and I read that comments an I see one that says "you should put you finger in there" I'm gonna give your comment a thumbs up when Im on PC. :)
similar is when you watch car rim when it have good speed then human eye see it like it is not spinning or spinning backward :) human eye can see only 60 frames per second, all above we cant see
@7BeAsT9 That's because of the frequency of the lights you usually see near roads. Your eye can't respond fast enough to freeze rapid motion like a strobe does, and you don't really see in "frames per second" exactly. Which is to say, your brain doesn't paint a full frame before moving to the next one.
where are this descriptions? sorry, but i don´t understand so much of internet. can u send me the link. i find out links for 110v, but i wanna put in my car, like police.
thanks for your help, sorry my english, i´m learn now.

The transformer (TR1) is a "flyback" type transformer with an air-gapped ferrite core, 10 turns in primary and about 33 turns in secondary. The other transformer is a flash tube trigger transformer.
It might be easier to make a mains-powered stroboscope instead of using a voltage converter but it's also a lot more dangerous and may require a voltage doubler. (is the mains voltage in Brasil 110V?)
hey thanks for your reply. i know i saw it on an other video of you (after i post my comment here hehe). i know this kind of flashtubes. is your flashtube still alive? if no, may you could tell me how long (time?!) it lives during your tests!
Yes, I haven't burned any flashtube in these experiments so far. I have run this about five minutes at a time. Few things can lead to tube failure:
-Too high flash energy combined with high flashing frequency. I used quite small capacitors (3x2,2µF, 300V, that makes only about 0.3 joules.) Tubes can handle higher energies than rated if the frequency is lower and higher frequencies if the energy is lower.
-Continuous arc in the tube. I have heard that few seconds of arcing can explode the tube.
its cool that you didn't burned any flashtube, special because you built this strobe yourself! i'm not really technique but i really guess its kinda difficult to make something like that without any failure with the tube. what frequences you can reach with your device? do you have a scale with frequence or rpm?
The maximum frequency of the trigger oscillator is about 55Hz with these component values and i think that it can be raised a bit thus that the main circuit can still achieve it.
...And perhaps even multiplied with lower current limit; however, this can lead to continuous arcing and maybe the voltage converter has to be shut down when triggering... I have noticed that big capacitor can also cause this, maybe because the gas is still partially ionized due to high flash energy and the rising capacitor voltage causes triggering when the arc is not extinguished yet... Yes, it's difficult when you start to tune it for the best performance =P
Do you have a memory or something to save the last frequency (you put it up to maybe 50Hz, do your device offline, do it online and you have still the last frequency of 50hz or will it start by 0?) no problem, mine english sucks too :D
Frequency is adjusted with a potentiometer (variable resistor) so it depends only on the position of the potentiometer. If I switch this off without turning the potentiometer and then switch it on again, it starts to operate at the last frequency.
dont you geeks hav anything better to do??

@Mihkellt
Flash rate can be varied between 1Hz and 55Hz with this configuration.

Hi nice video! What kind of flashbulb did you use for your stroboscope?

Thanks =D. I used a small U-shaped xenon flash tube (Trigger voltage ~5kV, supply voltage 200-500V).

In 1958,a magazine called "Electronics
Experimenter's Handbook" told how one could
make one's own stroboscope...to "freeze" the
movement of an electric-fan blade.
This invention of Dr. Harold Edgerton (R.I.P.)
was immortalized in a song by Tony and Joe
about the same time: "The Freeze",LOL!!

Damn!!! I was looking for something like this since long time ago!!
It looks really goood!
I'll build my own, and is it possible to watch something written in the fan when it seems to be completly stopped???

Yes, see my latest strobe video =) It has quite poor quality but I'll try to use better codec and a camera without interlacing.
OrmuScout 3 years ago
-Now without interlacing. Quality is better, no black lines on the video. However, YouTube's compression still makes it a bit messy.
OrmuScout 3 years ago
not only youtube... i know its really difficult to make a video of a stroboscope flashing.

nice! Did you make the stobe circuit? What frequencies does it run at?
oid123 3 years ago
Yes, the link to the schematic is in the description. Frequency can be adjusted by R13. It is between 1Hz and 55Hz with these component values.
