Really awesome stuff, thanks for sharing.

Some more mundane stuff ...... a 1N5401 diode

And a humble LED...

Yes I know you can see the insides visually on a clear one....but that's no fun is it

Marvelous to think this thread is only a couple of days old and how many images already?

Thank you Tautech

The MX-20 takes about 30 minutes to warm up, calibrate and flat field the camera. Then it is very simple to make the X-Ray images. Almost as simple as using a digital camera.

The setting of the correct KVp and exposure time does need to be set up carefully, but once set at a particular KVp it does not need much attention.

The dynamic range of the sensor array is quite forgiving.

Thank you for sharing this.

Any chance of taking shot of modern/current Intel desktop cpu shots ?

MrWizerd · « **Reply #56 on:** September 08, 2015, 02:15:57 am »

I hope you don't mind my saying that these could easily be offered I up as art, I do dabble in photography as one of my many hobbies and some of these shots would make excellent decor for a tech savvy art collector, heck I have seen black and white themed rooms that large prints of some of these would have fit well... aside from that it is Defenantly interesting to see build quality before we break in, for instance some of the probes had stray wires, I don't know and doubt they would be a problem in most cases is still interesting to see the quality like that.

Edit: Would it be possible to get a transister, something typical like a L337?

Had a few spares minutes so fired up the MX-20 again

First a modern Laptop CPU....

Pretty boring really but I was asked to X-Ray one so here it is.

Fraser · « **Reply #58 on:** September 08, 2015, 07:37:04 pm »

Now a transistor.... the MPSA14

You will see the bond wires but not much else. The silicon wafer/junction isn't visible when using the MX-20.

LM7805...

Again, sadly not much to see really.

Fraser · « **Reply #60 on:** September 08, 2015, 07:42:00 pm »

A TDK 4GB Flash memory drive.

There is a lot going on in a small space so interpretation is difficult. X-Ray does not really help reverse engineer the schematic in such cases. It might show how to get into the case though

Here is an unusual DUT.... a Computar CCTV lens.

I use X-Ray to investigate the number and shape of the lens elements. When experimenting with unknown lenses this can be useful. I have used this method to identify and characterise Germanium thermal camera lenses that are too valuable to dismantle.

This method also identifies the various screw positions within the lens to aid disassembly.

Awesome thread. I was just lurking at all the pics but couldn't resist from asking you to keep them coming

firewalker · « **Reply #64 on:** September 08, 2015, 08:23:37 pm »

The lenses contains PbO?

Fraser · « **Reply #65 on:** September 08, 2015, 08:26:40 pm »

Glass is dense enough to stop a 35KVp generated X-Ray beam.

No idea if the lenses contain lead.

The same goes for me! Those pictures are absolutely awesome, I love them!
Do you think it would be possible to look inside a vacuum tube? Guess the metal casing around the tube system wouldn't allow any view at all, even though it is quite thin?

Sweet Thanks! I was just curious what the inside looked like, I did not expect it to be ultra exciting, but it was informative. I recently watched a video on how the transistors were originally made/invented and was curious how that applied to modern transistors, and that answered the question. Thanks again!

A few more images to end the day.

First of all Thermionic Valves (or Tubes for US readers)

The MX-20 cannot penetrate the metal parts but then I did not expect it to.

Professional GPS Antenna

Fraser · « **Reply #70 on:** September 08, 2015, 11:16:04 pm »

AOR LA350 Ferrite Rod antenna. FET Pre-amp PCB is adjacent to output plug.

Adjustable foot from a Panasonic portable projector. Shows locking mechanism. I went for a close up to see more detail. I was not previously aware that the foot contained a steel rod foe strength.

Relay DPDT

HRC Fuse. Still looks serviceable
