Yes - not sure if the limit is the camera, the tube spot size or the resolution of the phosphor - there is a tradeoff between resolution and sensitivity of phosphors - thicker layer absorbs more but also blurs more.
Tried that but didn't work as well - the key is to get the subject very close to the phosphor screen - With the original one, there is a gap due to the plastic base. Cassette phosphor may also be thinner for better detail - not tried getting at the old one. Also, the X-ray beam density is much higher closer to the tube, giving shorter exposure
I have just found your channel. I used to use some of your Acord stuff at school, does that make you feel old, it makes me feel old.. I was going to do a bit of a YT channel like this but I just don't really have the time or, well, the desire to keep it up. Anyway thanks, it's all good stuff, I'm watching your videos whilst either fixing things, writing software, or flicking solder around.
What about mounting the camera in the spot where the original camera stood? Would the resolution be any different down there with the pcb's sitting on the original phosphor screen with the lead glass. I figure that would at least cut down on the radiation hitting the camera, and perhaps for light you could do a 30 second exposure on the camera with multiple bursts of the xray.
can you keep the xray on for a longer amount of time, eg 30 seconds? wondering if you make a larger lead can for the camera, then set the lens to f22 then do a 15-30 second exposure with the camera set to raw, would you get better detail? there seems to be a wife focal range on the film so a smaller aperture may be needed.
Mike, I think VC stands for Vision Components - a German "smart camera" company which makes customizable cameras with built-in processing for industrial applications, just like you said. My company used to use them for 2D barcode reading.
I saw that. I like the way he presents it as "hello, I was bored so I made an airport xray scanner, it's no big deal". As if playing with X-Rays was a normal daily hobby :-)
you get some great stuff and that TX is really nice .I just got a control unit for scanning metal pipes it goes up to 150KVp 10mA and has a really nice variac and adjustable ballast built as one transformer last repair it had was in 1988 is mad how things have changed ,If you get a chance check it out ,you'll have to excuse the poor cam work as im by no means a professional like you .Great vid and thanks for sharing that TX with us. John
Where do you get this stuff from. And more interestingly - how do you dispose of it afterwards, considering it's full of oil and full of "Warning Radiation!" stickers?
The colours on the more modern machines are used to distinguish a variety of materials, eg organic/inorganic/metals etc. I'm not sure if this specific model has this feature.
Maybe do you know where to get large CCD with scintillator ? Since i was using same method for making CBCT, but resolution is very bad. And yeah, direct exposure to x ray film gives 100x details, but take 100x longer to expose
Next step is to invent the interstellar teleporter using all those devices you show on your great videos!!!! Ahaha, always the best Mike, there's no channel as cool as yours!
Don't be sad! you can do alot of things with consumer electronics parts ;) And by the way, if you want to have kids stay away from anything that produces x-rays in large quantities...I'm not saying that the machine from this video produces alot of radiation or not controlled, but when a device is getting older gets other functioning parameters due to decalibration. even it was safe when it was new, if is getting old you should use alot of protection against dirty things.
Unless an xray source is expensive this makes it look like an xray machine could be done for pennies and weigh very little. A tazer, some flourescent film and a camerachip with usb in a metal enclosure. roughly speaking. You could also have multiple xray sources for computer tomography. xray should be illegal in medicine but for scanning stuff it's very good.
Mike, where do you get all that stuff from? I'm mildly annoyed that I can only get hold of broken consumer electronics and nothing else. Ebay Germany has become nothing more than a huge China-crap-shop with no useful auctions at all.
In Britain such machines fall under the Ionising Radiation Regulations 1999. As such the HSE must be notified and, as usual, you must produce a spectrum of documents demonstrating competence, safety procedures and measures. A site visit by HSE is not uncommon. So, although you and I know that yourself and the neighbours are safe due to sensible use, if a whistle is blown your setup does not stand a chance against some HSE muppets that are experts in deferring responsibility.

No - you need a tube with smaller spot size, probably also higher kVp to penetrate metal better
cool, But I noticed that at 6:07 a cap (c12) has a domed top, maybe the board had problems and that's why it got dumped. Fairly easy fix though.

really enjoyed this vid, especially the xrayed chips at the end! great work Mike!
Good morning/night Mike.
Oh, and do X-rays have a permanent effect on the camera/censor or is it only the single photo/video that is affected?

I figure that would at least cut down on the radiation hitting the camera, and perhaps for light you could do a 30 second exposure on the camera with multiple bursts of the xray.
Mike, thanks for another great video! Isn't the cap C12 at 6:06 inflated or is the camera angle?
can you keep the xray on for a longer amount of time, eg 30 seconds?

This is a very promising mod/tweak.
I guess you can upgrade this x-ray device significantly without spending extreme amounts of money.
Nice!
Cool, so the construction allows easy replacement of the built-in camera with something more modern and hi-res!

This was a very interesting one, Mike. Thank you!
Mike, That was extremely interesting. I wonder what the easiest way to increase resolution would be.
I remember! My first home computer in 1994 had serial-port mouse.
You do make some very interesting vids Mike. Thanks...
Live vid would be a problem due to low light level - need ~1 sec exposure at ISO 1600
In theory, could you replace the built-in video camera with a better (i.e. higher res/quality) camera?
Very interesting. What terminal software did you use?
Could a machine like this be adapted for use inspecting BGA solder joints?
I remember using a serial mouse on my 2nd PC. Thing was a pain to setup in every program that used it.
In Germany they probably have more rules about X-Ray machines...
IF the blurriness from the tube is a gaussian function then deconvolution should yield a pretty good, sharp result.
Why wouldn't it be - it's a self-contained unit, you can't point it at anyone...
Weren't mice PS/2 for a long time as well? I remember using a serial trackball!
The dc-dc converter amuses me a bit , didn't actually realize there was a little toroid in there :o
Great shot of the credit card chip with RFID. I always wondered what was inside those.
Next step is to invent the interstellar teleporter using all those devices you show on your great videos!!!! Ahaha, always the best Mike, there's no channel as cool as yours!
Mike, you could produce and sell simple cost optimized xray machines for 'desktop' use.
Getting your hands on one xray machine is cool, but TWO?!*
Where the hell do you get them? And how do you get them inside? Must be heavy.
i fricken love xray machines!
May I ask how much these things cost ?

Whoa, didn´t think it´d be submerged in oil. Pretty cool.
19:10
i waited for that moment whole video!
awesome!
VERY cool!
Pretty amazing result.
Though I know what you are doing is safe - I can't help finding it a little scary.
Great stuff .Thanks
whats an x ray lens made of?
Why couldn't they just use a ferroresonant transformer for voltage regulation?
are they legal to own?
Electrolytic capacitor C12 at 6:05 needs replacement...it's got that bulged-top thing going on ;-)
Why didn't you put the SLR camera in place of the old CCD camera below, you will have more room
thank you
There's only radiation when it's switched on. The oil is safe
Never knew that about mice, thought PS/2 was the oldé connectors
Could you not just mount the DSLR camera where the original camera was placed and get pretty much the same result?
This keeps the original equipment in the cabinet intact so it is still useable as a standalone X ray cabinet.
No obvious permanent effects
You could probably get better resolution from all your low resolution imaging devices through iterative deconvolution.
Neat cheers Mike.
Yay! Another Xray machine! :D
Worth watching this video even a second time, like I did it.
hmm, just pondering, very thin anodised aluminium with xray luminous dye in the pores??
06:09 Mike, that middle cap looks to be pretty dead. :)
45 degrees goddammit!!!
in Romania xray tubes are "Guns and ammo" and must be destroyed when the x-ray machine gets thrown out.
Vale Sarbu Another pointless law when you can make a rudimentary x-ray emitter without too much effort. lol
Hirose. Very expensuveu.
I also ponder how long you have been playing with this, your recent uploads have dead pixels, i thought it was my screen.
Serial mice are not uncommon and they work exactly the same as any other mouse! Windows supported them and DOS also!
Mike, where do you get all that stuff from? I'm mildly annoyed that I can only get hold of broken consumer electronics and nothing else. Ebay Germany has become nothing more than a huge China-crap-shop with no useful auctions at all.

You should check Ben Krasnow chYou should check Ben Krasnow channel and his experiments with x-ray and phosphor screen.
Wow.
Very interesting. What terminal software did you use?
