You are the "This old Tony" For Electronic fans and deserve more Subs. Best wishes over Xmas and a Fantastic New Year.

Hi Marco. Since you mentioned playing with fiber laser, I'm glad to help if you need splicing or cleaving. I have a Sumitomo cleaver and fusion splicer, plus common lapping, terminating and inspecting tools. Those were left from my power-over-fiber project during my PhD student career.

Exactly what I wanted for Christmas, a new Marco Reps video

👏👏 Laser Review

" I don't even get a pre-dented sheet metal enclosure......" ROTFLMAO Awesome!

Erbium is my favourite element. Largely because it was part of two separate research jobs. I studied it as a dopant in optical fibres and then again a few years later as an alloying element in steel. It was great in both roles. In fact I have never found a problem that Erbium won't solve (in cases where I have tried to use Erbium).

4:20 am im awake bored AF but my favorite KZfaqr just saved may day (night)

I can't stop thinking about the tube cracking and the powerful fan blowing the beryllium oxide all over.

Who would have tought this is a erbium doped amplifier. Nice one

THANKS that was an absolutely awesome episode Marco. All the best for the festive season.

Seeing new videos from your channel brings a smile to my life. Wish I could be on your level but we all have to start somewhere. I also noticed your channel because of the Eleksmaker video because I got that as my first machine as I'm sure many also did. Currently working on my workshop to open a small manufacturing "professional hobby" shop.

An EDF airplane with lasers? YEAH!

13:26 "Not a good idea to open these." .... *OPENS THEM*

Happy Holidays to you Marco and the pups.. another wonderful video!

love how you buy really interesting things & make them even more interesting

What a treat! A galore of insane projects and cnc!!! Thanks!!!

Wow, just wow! And merry Christmas.

Happy holidays to you to. You’re AWESOME ........ I love al your stuff. I got my diploma of Radio electrician in 1978 in Lugano Switzerland 🇨🇭we was studying more the tubes (valvole) and some transistor at the end..... I really enjoy your video. Thank you very much and Merry Christmas 🎄🎁

Your attitude warms my heart.

Awesome! Liebe deinen Kanal! Please, more of that Odrive-machine!

Many thanks for all the great videos throughout the year. I hope that you have a very Merry Christmas and a Very Happy New Year!!! Best of luck in 2019, Joe

Happy Holidays to you too, Marco! tolles Zeug!

Looks like you're gonna have a great holiday season. Merry Christmas!

You just made my Christmas so much better.

I must say i love Marco sweet voice, its soothening

Jeez you have no idea how much I would like this video if I could, probably one of your best videos so far in my opinion, although pretty much all of them are great

How far we've come since our 5mw HeNe tubes.... good times. Great video.

That's some crazy stuff. Super awesome!

How have I never seen Marco Reps before? - new subscriber! Happy new year!

nice editing as always, plus the quality content

Thanks for sharing and Happy Holidays !

Omg, this is one very interesting video ! Awesome ! Hurry up and let us enjoyed more of these goodies. Your video is an excellent Christmas present, thnxs !

Dir auch frohe Weihnachten! :)

Amazing video as always, thank you!

I have a very similar Argon laser, plus another that I've shown in a vid. I haven't used them in years, but they make for great heaters. lol And I used to build / splice EDFA (Erbium-Doped Fibre Amplifier) devices when I worked for Nortel. I would probably still remember how to use the diamond cutter and a splicing machine, but it's been many years. Splicing machines are fascinating to watch, no matter how many hundreds of splices I'd done.

Look mom! Another Christmas gift! Marco posted a lazors video! (Merry Christmas and wish you a million subscribers as you deserve)

Merry Christmas Marco !

Your channel is a dream come true.

frohe weihnachten :D hab mir auf deine empfehlung das andostar lötmikroskop gewünscht, ich bin gespannt 😄

Merry Christmas Marco.

Marco, you are like a drug, I keep needing more to aggravate my single brain cell! Enjoy the festive season!

Thanks for the vid. & Happy Holidays.

Please more of this Happy holidays

Clip Master Reps. Always seeming to find the perfect clip to throw in.

This is one of the best channels on KZfaq.

Your a hero Marco, a total hero.

👏👏 Laser Review 👏👏

>we’ll be sorely disappointed... Opens enclosure. >made in France.

Merry Christmas!!

Thanks, and happy hollydays to you too 👍😀🎅

I could watch this all day

best christmas present ever

You really do get to play with the coolest toys.

Awesome Work...!!!

Damn, for that price I'll finally have an application for those dodgy copper water blocks I made for my High School final project that I've always been too terrified to install in my PC. Only took 10 years. I'll keep my eye open for some of this stuff.

Learned a lot thanks

Cool! New video, I'm going to watch it tomorrow though, it's 4 am and I really really should get to bed.

I did not understand a single thing but hey okay you seem to have a plan and knowledge... subbed for that !!!

This Video was amazing!!!

you are such a lucky person to work with these things....

I used an AOTF for hyperspectral imaging. Perhaps you could use your AOTF for spectroscopy.

Hi Marco, Can you provide more details on the configuration you did to get the BLDC to bounce back like that, please?

*@Marco Reps* that last blue unit... is that step looking piece setup as mirrors would be in a parallel array? Is the surface coated, or have a FS type mirror finish? I love the compactness of that unit, very clever!!

That corexy belt arrangement is off. They have to be parallel and straight while accounting for belt thickness. Check out the UMMD 3d printer blog for a thorough explanation.

Wow! Love Your channel!

Again awesome Video 👍

Frohe Weihnachten :)

This video is dope!

I love you videos and your work it's always very intriguing! How do I get my hands on one of those laser drivers?!?! I have a fiber coupled diode laser that needs 1.2 ish volts and up to 90 amps. But I'm sure I could still have plenty of fun at 50A.

Maybe you could try to automaticly solder circuit boards with the laser new laser machine....

Amazing. New sub keep up the content!

Marco what a clever guy ..in a mad scientist sort of way

you are insanely smart, and seemingly somewhat of an expert across what seems to be quite a large amount of scientific fields. You have this weird omniscient quality. you remind me of the Internet or smth Love from Denmark

LASER REVIEW HAHAHAH Great video Marco! Even you are on the latest trends! Keep it up. Very interesting indeed.

I need to get myself one of those

I really dig your humor :)

Great video! As always. I wanted to ask you for advice on which laser is best to buy to make a deep engraving on black granite. I tried a Chinese 15 watt laser (the real output turned out to be 4.5 watts) but it doesn't even leave a mark on the granite.

Can you please provide the value for the ACAS0606AT resistor? Or better yet, a parts lists? Thank you!

Thanks for the video :) Nice toys

Have you gone in more detail about beam combiners and fiber hardware? I'm looking to couple my 40w CO2 laser with a couple diodes to allow for fine frequency and power adjustment for a multi material SLM machine I'm building.

Hi Marco Also, how happy are you about pos. accuracy of your belt system? How did you align the laser the first time? Do you plan on adding a case to the system? What about a adjustable table? A bit much but I think that would make a good topic ;) Thanks for all your good work!

Wow. Es gibt nur wenige Menschen, die sowas machen. Und dann auch noch als Hobby in ihrer Freizeit! Was machst Du beruflich? Das kann nur entweder Fußböden putzen sein, oder fürs DLR irgendwelche neuen Weltraumtechnologien erfinden.

Lasers, laser power supplies and drivers, cnc, grbl, stepper systems converted to homemade servo systems. It looks like we asked Santa for the same things this Christmas!

Finnaly you went completly mad Marco :)

Take me back to my early engineer career... First job was testing erbium fiberlasers. Basically a fiber amplifier rebuilt as a laser

When I was a grad student at Stanford our lab had a 5W argon ion laser. When it needed service I would drive it down the road to Spectra Physics in Mountain View.

Hey dude, yor videos are awesome, but I've got another question: could you make a video about how you did the controlling for that big brushless fan?

I didn't understand a word you said but it was cool!!!

Love your videos :D

10:16 - now this is awesome stuff...... mhmm thats really nice, thats how a machine should work, brilliant

Resistor diode array is there for ESD protection for the laser diode, not for reverse protection.

So you are the guy who bid me over on ebay for the argon ion laser... :-)

What a videos man awesome

Seems like you are missing the driver of the french A+A PCAOM. They are the most efficient PCAOMs money can buy and are worth a lot more still then the money you paid complete (I have one). However alignment of them is very crucial to achieve the optimal efficiency. Gas lasers are never really efficient but that argon can be a tad higher in output perhaps.. I do know argon/krypton is even less efficient.. my argon/krypton purelight star 2 C outputs 5.6 watts but takes in 18000 watts.

Awesome! As usual. Can you please let me know the details or a link to the motors shown at 7:11?

How about a pulse xenon-ruby laser cutter?

nice need to get mij hands on a couple of those diode lasers to

man that CO2 laser is a nice christmas light. Also more on that machine pls

i was holding my breath when you were messing with those fiber optics.

Oppp's there's one laser gone sound real familiar. LOL
