X-ray timelapse of fluid movement in plants, stop-motion animation, sensor teardown/repair

I repaired a large digital x-ray detector and used it to record timelapse and stop-motion animations of plants, a clock, and a camera lens.

Thank you, Amir, for the X-ray sensor and software!

Some of the most worthwhile content on any platform. I appreciate you putting these vids together. Thank you.

I love the way Ben is so matter of fact and modest when he's one of the smartest guys on YouTube. He talks about figuring this out like he's just worked out the defrost setting on his toaster. Such a refreshing change to all the "empty barrels". Love this channel!

"Might even say it's enterprise grade"
As a professional programmer, that sounds about right.

Good gravy, this was awesome to watch!

[JoshStLouis]

The amount of effort put into these videos is truly astounding. An amazing experience every time.

When was working on radiotherapy software 15 years ago I remember one such panel was $150k+. They seem much more 'affordable' now with one less zero at the end. A good catch you got there. I'm wondering how heavily the phosphorous layer is bonded and if such a panel could also be used for a very sensitive telescope

Those plant time lapses are sensational. This should be submitted to NatGeo and and whatever major botanical publications exist, because I'm sure they'd be amazed.

[RichardGreco]

The casual demonstration of your impressive technical depth still surprises me after so many great videos.

Thank you Amir. Counting child-windows may be of interest - maybe not relevant for this task however. To cludge automate industrial apps (Siemens LCT) I have counted the number of child-windows (using VB3) spawned to determine the right time to send the next sequence of keystrokes. Time taken for a child-window to spawn varied greatly in my use case and dependant on the network of the very remote devices and detecting when a child-window spawned ensured maximum thru put rather than coding for worst case. It tuned an ~ 60min task into a 1 minute setup and run and walk away task. (Also took me about 3 weeks to get to that point)

Former GE Field Service engineer here. That is a GE Flashpad. I am absolutely amazed what you found out reverse engineering it. It's used on the XR220 mobile xray product line as well as the XR6x6 rooms. The bottom connector is used for plugging it into table/wallstand bucky tray for data transmission and for charging the battery. The battery port can also be used data transmission as well. Your channel is amazing. Please keep up the good work.

I've done enough of these kinds of things to *seriously* appreciate how much work goes into something like this.

I know when you're working through that kind of uncharted territory you can spend dozens of hours just building a rig to test something that turns out to be a dead-end. There's so much work that goes into all those little details you can't even begin to cover in a 20 minute video.

Really glad you succeeded and the result is spectacular. The camera lens animation is fantastic, I'd love to see it in a full resolution looping video so I can absorb every detail.

This is one of the most amazing things I’ve seen in a while. Do you realize that so many photographers and artists would kill to work with this thing?

[WizardTim]

Love the timelapses!

I'm also surprised by the teardown's lack of ingress protection, in the medical setting those are often placed under patients that are leaking fluids and in the industrial environment those are usually used in very dusty and often wet building environments, surprised how clean this unit was inside given that, I imagine this one is non-rugged intended for clean lab use?

I’m impressed you were able to even obtain the software for the sensor, most medical devices end up as e-waste because you can’t get the software or physical licence dongle.

I’ll also mention just be careful with those cheap SBM-20 Geiger counters, they’re useful for finding high energy radioisotopes but they come with a lot of measurement caveats, they’re not very sensitive to < 50 keV X-rays, are prone to reading 0 when saturated and CPM to dose conversions are only accurate for their calibrated source (usually Cs-137 or Co-60). However, you’re clearly taking good safety measures with remote triggering and such.

What gorgeous time-lapses! Thanks for the work. It might be cool to see something metallic that strongly reflects x-rays. The scatter might be really pretty in time-lapse.

[BGraves]

I haven't watched it but I know it's the coolest thing in the world. Strap in-- we're about to go for a ride!!!

Nobody does quality over quantity like this man.

[benyoung]

Now it is time to set up a rotary stage and turn it into an xray CT. I would love to see you do some dimensional metrology with it!

[patrick]

I love that you used a tape spool to actuate the camera focus. That's just as cool as everything else in the video! Glad you included that clip

[douglasharley]

20:06 lol, one of the hugest understatements in the history of the universe!...i bet significantly fewer than 1000 people on the whole of earth could do that troubleshooting and fixing. as always, utterly astounding work, much thanks.

[yachalupson]

Just phenomenal - you've excelled again.

What about fungal growth through media? Or root growth.

[Jeremy_Fielding]

Great video! Its amazing how those tiny problems can hide from you... gave me flash backs LOL
