- Powering my homemade TEA laser using a Wimshurst machine, an electrostatic machine that works by turning a crank; no need for a powerful high voltage power supply. The cool thing is that if we'd known how lasers worked this could all have been made back in the 1880s when the Wimshurst machine was invented.

That is the first crank-powered laser that I have seen. Cool!
Applied Science Yeah, low high-tech!
@@RimstarOrg now build bigger capacity. or aren't you allowed in your country
Its great when two projects come together so well.
Laser cannon on a Wright Flyer . . . cool! Well made video Steve! -Ritchie
SonicDadDotCom Thank Ritchie! It was a lot of fun doing it.
Damn, that was fantastic! Is there a way to calculate the output power of the TEA laser?
the Hacksmith Thanks! I'm glad you liked it. Maybe a photocell can be used to measure the output power.
The voltage is some what 100kV? The current like a few uA tho. Wikipedia: "several tens of microamperes". So 100000 * 0.00001 = 1 Watts? Seems quite much, given the fact that laser pointer has a few mW. Although the beam also is quite short.
@@dreamyrhodes The very short pulse time of TEA lasers makes the pulse power very high -- I've read elsewhere that the power (energy per time) of these pulses, which last only a few nanoseconds, is in the megawatt range -- but with one pulse every twelve seconds or so, the average is tiny.
Loved the Wright Flyer going "Pew! Pew! Pew!"
Nice touch! I got a laugh from that!
USWaterRockets I'm glad you enjoyed that! It was fun to make. I actually did think of going "Pew! Pew! Pew!" but decided to go with some better sound effects this time. I did go "Pew! Pew! Pew!" in my video about adding lasers to a TIE figther and the Enterprise though th-cam.com/video/VxIEV27AjWQ/w-d-xo.html :D
Cool! Now I have to find a way to work "Pew! Pew! Pew!" into one of my videos. That's going to be hard...
Incredible !
You got SO CLOSE with this design. If you could combine this system with the handheld Wimshurst machine, you would have the ULTIMATE Steampunk Ghostbusters prop. In a perfect world you have the Wimhurst machine hooked up to high speed gearing and a heavy-duty winding spring worn upon the back and the TEA laser safely contained in a boxy black wand with a collimating lens. Then, when people call it a proton pack, you get to correct them and show it's a PHOTON pack, perfect for denying vampires and other creatures of darkness the ability to approach.
That certainly would be the ultimate steampunk laser! Must be wearing goggles, though, not for safety, for the mad scientist look.
Old tech powering newer tech - powering my homemade TEA laser using my hand-cranked Wimshurst machine.

I'm glad you liked it. Thank you!
2 things that i've never made, working as something that i now HAVE to build haha !
Great demo and some neat camera pause shots, enjoyed it :)
slider2732 It'd be cool to see what you come up with for a TEA laser! And yeah, a laser beam lasts too short a time, definitely needed those pauses.
Dang that is so creative! Awesome video, thumbs up.
Cool laser! Nice work. Alexander Graham Bell had a few patents in 1880's using focused light for his photophone (235,199 241,909 235,496). He was transmitting and receiving sound with a beam of light. They could have been more advanced than we know.
Michael Meadows Oh! Bell's photophone is too cool! This is the first I've heard of it. Thanks!
Great work, thanks for showing!
Great job! That beam is well focused. The aluminum sheet and plastic made a nice capacitor. I just uploaded a video showing a few voltage multiplier circuits with my Oscope. I would try using the 5KV Neg output from the microwave oven schematic shown in that video. Just be sure to stand back when it is powered up. I bet you get a really nice steady beam. :-)
A TEA laser can only operate in pulses; the nitrogen component of the air in the gap needs time to either relax back to ground state (the emission goes from the second excited state to the first) or to be replaced with ground-state gas via air circulation. This design has poor circulation between the electrodes, so is limited to, at most, a few hundred pulses per second. To the eye, it would look like a steady beam, but it's still only a few nanoseconds every few milliseconds, or about a .0001% duty cycle...
Cool video
EPaR - Aidan Gieg Thanks.
This project has potential Steampunk written all over.
John Ratko Yeah, I love when you can do awesome stuff with low tech.
RimstarOrg Absolutely.
👍🏼 so the faster the spark, the faster the laser beam flashes?
I wish we has you tube back when I was at school, learning would be so much more fun and interactive.
Green Silver There's one laser beam per spark if that's what you meant. It just takes a while to build up enough charge using a Wimshurst machine in order to get a spark. It'd probably take around half the time if I remove the Leyden jars.
wow holy fuck. I always wanted to build a Wimshurst Machine with 3d printing... but never got to it because was not motivated to do that just for sparks. Now that laser could be quite a motivation. *pew pew* :D
Also imagining that they could have had that in the 18th century already... the plastic foil insulator could maybe replaced by a parchment or leather, if it's dry. Maybe impregnated with some Linseed oil? Or bone glue on a paper? And the resistor could be made from a coal rod or graphite.
That's quite steampunky :D
you said balls....lol
Insane !
now all we need is a Ruhmkorff coil to make it super efficient
Kool stuff! It's always an awesome thing to see when others are experimenting, inventing, and discovering new and innovative ways to harness something out of new and old tech. I would be making videos like crazy but, my computer has been running so slow. Once I get a new one I have a lot of video ready to edit and post. I haven't stopped tinkering. Just haven't been uploading lately. :/ Hopefully, I'll get a new laptop soon though.
0:27 Best. Animation. Ever.
Oinikis :)
Here's a similar set up, except the Wimshurst machine is motor driven and the TEA laser is also used to pump a dye laser. The dye laser uses hi-lighter content for its dye. That's basically it, although it takes time, persistence and practice to make it work.

Actually I watched a few of your dye laser videos recently. Very cool work. +Daniel Shoemaker has been pointing it out in the comments to my How to Make a TEA Laser video th-cam.com/video/v9sKqGC3t-0/w-d-xo.html since he's gotten a nitrogen laser to work and is now working on doing a dye laser too. The only thing stopping me from trying it is time, mainly, and then finding a glass rod to disperse the TEA laser light linearly across the dye.
great channel! I want to see the tea laser work with a Kelvin Thunderstorm! I'm working on it now :)
A steampunk version would use sheet brass or bronze, copper foil and sheets of mica. Steel and iron might be in it too, but no stainless steel. Shiny bits would be nickle plated, not chromium.
You are amazing!
"Plastic, which wasn't invented until the 1900s." Beg to differ, celluloid was invented in 1855 and was formed into many objects -- including the first flexible photographic films from the early 1890s (but could have been made in that form by around 1860). The Wimshurst wasn't invented until 1880 or so, but very much "lasers before airplanes" -- except that dyes that would show the invisible UV beam from a TEA laser didn't exist until the 1920s...
Oh wow, I always thought plasitcs started with bakelite, which is what I had in mind but right you are en.wikipedia.org/wiki/Celluloid Thanks! Regarding dyes that would show in invisible UV beam, I made some from spinach and rubbing alcohol for this video th-cam.com/video/6-QdXyI217k/w-d-xo.html. I don't know if they knew that back before the 1900s but it sounds like it would have be makeable.
@@RimstarOrg Fluorescence wasn't well documented until there were strong UV sources that didn't have (much) white light component. Filtering arc lamp light might have worked (but a suitable material or dye again wouldn't exist until analine dyes came along); otherwise, it would be a matter of a discharge lamp or Rhumkorff coil with the correct filling (mercury vapor?) to get enough fluorescence to see from natural fluorescent materials.
When you come back and fill out the options you skipped in the tech tree.
I had no idea that one could make air lase... I'm sad that I didn't know that until now.
Autorom podziękowania ślę serdeczne . Budzimy iskierki WIEDZY by je rozdawać.. Sprawdzaj, doświadczaj.. ignorancją arogancją wspieraliśmy system.. podaj dalej. Świetny materiał edukacyjny. '' wystarczy zacząć od siebie zdając sobie sprawę o czym tu jest mowa. a treść przemówi do WAS''. .Polecam.
*chuckles brass balls.
Would a electric fly swatter do the trick too?
Nope, an electric fly swatter would be too weak.
@@RimstarOrg Thank you
How does it work？
Video: balls
TH-cam bots: DEMONETIZEEEEEEEEEEE!
You can churn this shit up, umma gunna split it up and away.
great video, interesting use of hand powered high voltage generator, the foils make a collector capacitor? greatest dilemma is utilizing these machines to recharge a battery that could be used to power the wimhurst in a self loop style which could result in a testatika!!..im fascinated by the wimshurst as much as disappointed by it..
professorfidelcat There's a small gap between the two foils that are on top of the transparency, so altogether the foils make up two capacitors. The foil underneath the transparency is shared by the two top foils.
RimstarOrg wow, a capacitor with a lower common ground capacitor..ingenious!
professorfidelcat Agreed. The purpose is to make the discharge in the lasing channel, the gap between the two foil capacitors, as fast as possible..an ingenious solution.
RimstarOrg lets apply the wimhurst to several methods of utilizing static energy to charge batteries efficiently using patent methods of herman plauson
How far does the laser reach?
PCFW I've never test it for maximum distance. All lasers' beams spread out somewhat, but a TEA laser's spread is more than most. In my demonstrations video here th-cam.com/video/Fl_cAHuGlko/w-d-xo.htmlm52s you can see the spread is quite large for only around 3 feet/1 meter. Since the brightness decreases with the spread, I guess it'd start being dim once it's gone far enough for the spot to be a meter or two wide.
RimstarOrg thanks
But how it works ??????
It looks like it uses static electricity stored in a capacitor which is fired between the cathode and anode which causes dielectric breakdown of the air between the cathode and anode resulting in a plasna channel which the rest of the stored energy flows through the ionized air. Within the air is nitrogen being ionized which in billionths of a second generates photons and bam you have a laser!
:)
Now use this beam to strike a metal plate and charge up a capacitor, Tesla did this with radiant energy from his arc machines. There are some radiant energies in that be from what i noticed.
