Dichroic X-cube prism removed from projector. Laser experiments

[@BushCampingTools]

Cool video. Great for family home experiments in physics. I'm subbing, plus that brother of yours must have balls of steel to drive tat train through that dodgy tunnel! LOL!

[@mca0824]

Thanks for the sub, He always told me the tunnel was crazy.

[@BushCampingTools]

@@mca0824 LOL, he was right! BTW I really appreciate your channel there. I used to work as a researcher at various different unis and one always takes it for granted (well almost) that one doesn't pay personally for all of the research gear. Now I work for myself and being able to know where to get ones hands onto "cheap scientific gear" is a must LOL!

[@mca0824]

@@BushCampingTools True. When your just doing it for enjoyment or personal knowledge the price can out way the result.

So, I have a 25 mm cube from an NEC projector. Mounted in an aluminum frame. Need advise on how to remove the aluminum without hurting the cube. Plan to facet the cube.

[@hullinstruments]

Facet the cube? Is there any particular reason? Sounds like an interesting project… But keep in mind Most of the coatings are on the exterior. Technically it’s 4 triangular prisms glued together. I guess that’s why they call it a “X-cube”… because when you look down from the top you can clearly see the separate pieces of glass. Some of the coatings go through the interior of the cube… But they won’t really be visible once you cut away the face. Just a tiny little cross-section of coating a few microns wide. Sounds like a fun project regardless. I’d Be interested to hear if you have any updates on this project? I’ve done quite a bit of faceting myself, but that’s been years ago. Last machine I had was a facetron… When they first came out with the really fancy version… So that shows you how long ago it’s been since I’ve cut anything, Except the line in the grocery store.😂 I also enjoy restoring faceting machines. vintage and modern machines… Like the graves Mark four and Mark five XL, old ultra tec, lee, and others… My skillset is best suited for things like that. Equipment restoration and calibration. I’m not very good at being creative, or spontaneous. And that’s important when cutting gens. Although at first it’s important to follow the math and the long established designs… After you’ve cut a few hundred or thousand stones… Do you want to start playing a bit… And coming up with your own designs. And that’s not something I’m good at. I’m good at working to a design… Following a complex blueprint no matter how long it takes. I could probably build a working nuclear reactor in my lab… If I had the plans. (not bragging because A regular 12 year old can do the same thing😂) But I’m not smart enough to design and innovate. I just have to trust the engineers who made the blueprints… And let the folks with the higher IQs have fun with innovation and creativity. But I still enjoy being part of the craft…… But instead of doing the cutting…I’m buying high-quality machines from the 60s, 70s, 80s, and even some modern machines……Completely tearing them down and sand blasting them to the bare castings. Then restoring and calibrating them to perfection. To a much higher tolerance and accuracy than when they left the factory. (which really is overkill… because the manufacturers did an incredible job…But it’s something I enjoy.)i use more modern materials and coatings…so that things won’t wear out and will last forever. I’m a machinist by trade, but do woodworking and electronics for a living. Two separate businesses. I have an electronics lab, and my main business is component level circuit board repair….. for a wide range of industrial and government clients. Also a bit of metrology and optical test equipment calibration. (spectrometry and such) and that’s how I became interested in lasers and optics. It’s a golden age of equipment! If you know where to look you can get an entire professional optics laboratory complete with lasers, an optical breadboard, and all of the equipment. For pennies on the dollar! government auctions, auctions at colleges and elsewhere in academia, and Ebay are your friend! I’ve spent a very small amount of money… To amass the type of equipment I have. Buying decommissioned laser equipment and optical lots from government and industrial auctions. At least $50,000 worth of optical equipment if I had to buy it new. And I paid less than 10% of that. Way less! Some pieces were bought individually… But a lot of it was purchased in several lots that would be auctioned off all at once. Pallets full of stuff… For pennies on the dollar. And you know how the government in large corporations work… They buy stuff they don’t even use. So a lot of the stuff was either brand new or like new! Sorry didn’t mean to ramble on. Would love to hear any updates about your faceting adventures.

I have one of those X-cubes that just today I pulled off all this metal that was stuck to the cube and oh boy it was really stuck on there!! like the first thing to come off with this plastic bit with a little prying and then I pried in between two of the metal parts and one came off with left two on ether side, now I tried prying it off from the top but it just split in half and I later found out that there was glass in the metal bits so I had to be carful other wise I would get broken glass everywhere, finally I used some broken flat head which was really small to get into the little holes on the side and that finally pried off the two remaining metal bits off the cube and oh boy... was it worth it? I don't really even know anymore :/

[@fakenews7266]

I cooked the green coating off of my 1-inch optic glass "X CUBE" with a 1000 MW ( 1 WATT ) 450 nm class IV LASER, it has burn marks only on the green coated side

[@SlimJimLockpicking]

Good Video Feller.

[@nicolasvanhoorick3430]

can you do a video with the really cheap 1 mw green lasers on ebay and see their real power?

[@mca0824]

1mw or 1w ? The 1w green lasers I have purchased are usually around 80 -200 mw and the 1-5 mw lasers are actually around 20mw. Have you seen one in my videos ? I will be happy to put it into a new video.

[@nicolasvanhoorick3430]

yeah ive seen alot of 1 to 5 mw lasers on ebay for like 3 dollars and was wondering whst their true power was as Ir leak is really bad for your eyes because cheap ebay lasers have no filter.

[@mca0824]

Those cheep laser run high and the expensive one run low. Always best to error on the safe side.

[@slap_media5296]

Please do another laser review vid but put the links in the description

[@mca0824]

Sorry for not uploading for a while. I hope to have more time this year for uploading.

[@LumenChaser]

Make a yellow laser with this cube! Just put a green and red beam together, please make a video on it!

[@mca0824]

Nice idea. I will give it a try, if I get it to work I will list you as the person with the idea. Thanks.

[@LumenChaser]

Michael awesome, I hope it works out I'd love to see it

[@Jwdude123]

I have conducted similar egg-spare-eh-ments...

[@shannonanderson3580]

cool

[@luckmall]

Here is plenty of cubes conected to motor and light source from the side: kzbin.info/www/bejne/fpacpGiImL6Im5Y

[@thewills8607]

The cubes are £4 on ebay wtf is wrong with you? They dont cost $60

[@TomaszPlawski]

The ones on eBay (or even cheaper direct from China from ⒶⓁⒾⒺⓍⓅⓇⒺⓈⓈ kzbin.info/www/bejne/gXmxh2RubJqXZ5o ) are generally manufacturing rejects with some flaws

[@destravlr]

Your attitude needs changing.
