Great teardown. Nice to see inside these machines. They have a fascinating history.
Heartstream was founded in 1992 with the mission to create a defibrillator for laypersons. Their first product was the ForeRunner in 1996. Heartstream was purchased by HP in 1997. Two years later its division was spun off as Agilent Technologies. Then in 2001 Philips purchased the entire Medical Group from Agilent Technologies.

your coolness level went way up in my eyes when i saw that xray. bravo sir, bravo
I looked up HP Heartstream. In 1999, Hewlett-Packard spun off its Medical Products Group, including the Heartstream Operation, into
Agilent Technologies. With Agilent, Heartstream introduced a new AED and Laerdal Medical marketed this device as the Laerdal Heartstart FR2. The FR2 evolved
into the FR2+, with the addition of an enhanced feature set, in 2001.
Heartstream became part of Philips Medical Systems in 2001, when Philips purchased the entire
Medical Group from Agilent Technologies.
Any stuff that you don't see on a zillion other bits of common gear - high voltage, insane current, funky packages, stupidly expensive stuff, extreme sensitivity or precision, wierd physics devices, bizarre optics and anything with a scary warning sign on it. Wonder what they'll do with the Hadron collider now they've found the Higgs. Hey, CERN people, all donations welcome!
Only half an image - it was a bad solder joint on a connector in the sensor array.
Do you by any chance know any of the service/setup passwords?
Great video. Where did you get that burner nozzle for the MAPP cylinder?
A very interesting presentation Mike. I myself was about to check one of these devices. You did it for me and answered the question I suspected. That consumer camera batteries were inside. Maybe if the device were a snap on cover , the batteries could be replaced and save the purchaser £100s of pounds! But I suspect not sadly. The cost for new batteries are extortionate for these devices. The Laerdal Ambulance Defib’s can be charged both on board an ambulance and externally via a charger in the mains socket. Thanks once again for a very informative video.
Not really - the way the detector works isn't very amenable to altering, and the resolution of an x-ray is limited by the tube's spot size. I now also have a smaller mailroom x-ray which is small enough to keep for a while.
awesome tear down!, that cap could come in handy on some HV projects!
the X-Ray machine is a excellent find too!, I imagine you will be keeping it for scanning potted items and so on?
Awesome teardown, as always! Can't wait for the next x-ray'd teardown
My school has a similar unit, and the batteries have a "training" version which makes the unit go into training mode. In this mode, the high voltage is disabled.
Heartstream became part of Philips Medical Systemsin 2001, when Philips purchased the entire
Medical Group from Agilent Technologies. (Extract from linked manual). Nice video.
I'm sure people have worked out the optimum charge value to resuscitate the majority of people without causing harm.
Drain from an LCD will be a tiny fraction of the battery shelf life so not an issue.
A check button is no good as unit may be behind a break-glass panel in a public space.
Where else?
Not sure how much these cost new - probably not quite as much as that scope.
Wondering what the two side parts of the LCD indicator would be used for? I can understand having it ON/OFF but why not a square?
Ebay obviously - stupidly cheap as it was faulty (before I fixed it) , and the guy wanted the space to make way for ex-Olympics gear, Paid more for van hire and diesel than the scanner - will probebly cover the costs from scrap lead
@ 7:23 , whats the difference between clearance and creepage in this context?
Why are those cutouts made for creepage? Does'nt glass epoxy have a higher dielectric strength than air ?
Is this the first time he revealed he had an x-ray machine? Awesome!
I was watching the guys servicing one at my local bank. there is a very nice XP computer inside, and I really want one, so many useful things you can do with it, though you might have a shipping problem, as well as other issues as it uses depleted Uranium for shielding.
How big is that CF card? I need a bigger one for my old 386 laptop; I am currently using a 32MB one as the boot disk...
@mikeselectricstuff where did you get the scanner from ? I have been looking for one for a while.
What was the initial fault on the xray machine when you bought it?
Doesn't really have enough resoluiton, and takes a huge amount of space. its days here are numbered.
I thought it was a reflow machine at first glance , do you work in the forensic field, why the xray?
Holy crap you have a friggin X-Ray machine that is awesome. You should do a shop tour vid.
Wow, how did you get that x-ray machine? :o)
Thank you for the video ; but what is the name of the IGBT module ? I could not find that module.
IXYS V9141 137A
Open an old Panasonic plasma and be greeted with a huge number of IGBTs (one I repaired had some 10 high-voltage IGBTs and about 30 MOSFETs), 400V mux ICs (with 480/720/768/1080 output lines), etc. They use something like 200V drive waveforms at 200kHz.
Loved the too brief swinging camera tour of the workshop - future video request! Hey, might even be handy - if you can't find some tool you could run a contest and we all could scan the video.
I guess you weren't tempted to try the defibrillator out first?
Awesome! ....that magesium shielding plate should be hours of fun!
Little bit of tantalum in there. Also cool x--ray scanner.
it's not the first time you have something like this.
obscure electronics form e-bay.
How do you do that?
really great teardown again..
and i like the xray-teaser a lot :9
When proceeding with teardown and undoing the capacitor's connections, is there any risk of getting shocked, even when powered off and the battery removed? Just curious.
***** Yeah, that makes sense. Good point.
Can you tell me where i can find the video about Dave's 100k scope? Thx!
Stick around and watch the videos he did for the x-ray machine - he even goes as far as patching its firmware to get it working. They're both excellent channels :)
Airport x-ray machine? You amaze me with each video :) Where did you get that from?
can the cap be used for a coilgun ?
You can get them on eBay for about $1000 and up. A rather justifiable investment if you have use professional use for it, as I'm sure Mike does. He might have gotten cheaper through contacts, though. Another tip, again from Mike if I recall correctly, was to go to the local veterinary and ask to use their x-ray machine, of course against an appropriate payment.
Was that >1KV capacitor ever discharged?
By "other methods" I thought you were going for a vice and whack it with a hammer. ... But then ... WTF!!
the multi-pin chip might be a TMS series DSP chip.
Interesting to see what look like ASICs. One possibility is that current FDA and other regulatory requirements frown on software control. Essentially, manufacturers need to prove that the probability of a dangerous malfunction is below a specified level. Some guidelines require that in this calculation, the probability of failure of a software module must be taken as 100%.
I wouldn't be too surprised if these ASICs were a redundant ECG analysis system to inhibit shock in life-supporting rhythms
Have you ever stuck your arm into the XRay machine?
In reply to all comments about x-ray machines please leave them to the techs who have the training to safely operate them
You must never expose yourself or an animal to x-rays IT WILL KILL YOU if the high voltage doesn't get you first
Just enjoy watching others on you tube
I really enjoy watching electronics vids and I learn a lot but I just wish some people would think before they post their comments
Again thanks for another great vid
where did you the x-ray machine ?
Scary!
What's the mic for? So that way if the user is like, "OH MY GOD! OH MY GOD!!!" they might be more likely to avoid lawsuits against the user? Or...?
That X Ray machine is Awesome for things like this!!, I'd make room for it & keep it!
X-ray?! You got some quality kit where you work. Looks like an airport one.
LOL Airport X-Ray Scanner @home. Nice Teardown!
Patience...! See twitter for sneak preview @mikelectricstuf
Ha! I said a while back that you need the xray next! :p (username was stickercam). I really wanted a thermal camera the other day for some temperature testing. Was the xray for fun or work?
Why are some electric components potted?
Mike casually x-rays this potted module with his own x-ray...
There was a LOT of what seemed to be high pin counts cpus in there for a little thing like this, wth? It wasn´t exactly a 5GHz spectrum analyzer..
I was actualy waiting for you to get a General Electric Itemiser, also airport security stuff. See how it recognizes ions in substances...
There is one for sale on ebay foor 400$...
Hello Sir, Great videos. (Question), Could someone just replace the basic camera batteries with new ones rather than spend $260 on a new battery?
Should work if you manage to reset the battery control chip.
8:40 - every workshop should have one :)
Wow ...cool ! Mike has a X-Ray machine in the shed :-P
mind telling us how much you paid for it? I have to go to my dentist who lets me use his xray machine for small things ;)
For peace of mind, you might consider throwing a warning in these kind of videos about the dangers of high-voltage capacitors and why it's a bad idea to handle high voltage circuits unless you've made sure they're discharged...
There are plenty of other people doing electronics tutorials on CZcams. I'd recommend Afrotechmods, myself.
hahaha, watching the part of the video with the bandsaw at high speed made me flinch! (i guess its a pretty good way to make engineers nervous)
I never thought I'd find this sort of thing interesting. Apparently I do. Subbed ;P
It also failed the self test because the battery charge was too low, hence the x on the secondary display
X-ray! You are a madman! :))
I see Mike has a new toy. :)
13:39 you got mail! (Thunderbird?!)
"Heart Start"? Even the manufacturers have fallen for the TV misconception that defibs restart flatlines?
damn, i would reeaaaly love to have that big caps, ideal for a coilgun :/
Yey!
I see they have $500 x-ray machines on eBay. (for dental use I would guess) From Hong Kong.
I'd seriously wonder what corners were cut for those! If its anything like a cheap wall transformer...... Hah!
Lol, the X-ray, soo epic !
I just got a battery pack for a similar model and ripped it apart... It uses a Dallas DS2436 (datasheets.maximintegrated.com/en/ds/DS2436.pdf) to control pack lifecycle.
You don't have a mate called Delboy, do you:)
This would have been a real unit used on real people, the training ones lack the LCD displays (instead have a sticker for the main one and a pull out strip for the battery indicator at the top right)
The training ones also take a slightly different battery loaded up with D-cells cas theyre cheaper than the real things. They are nt cross compatible for obvious reasons.
Source: Ive been trained on a number of these units and theyre all pretty much the same

£100 (plus £160 for van hire & fuel!)
lol at 1:57 theres a NSA action... wonder what that does :P

NSA seems to stand for No Shock Advised.
It spy on your heart
Another method. Enter personal xray machine. Well that escalated quickly.
If they're FDA approved they can't be doing much wrong...
It's possible it's an optimal design but my faith in human reasoning is not so great that I assume it.
Btw, exactly how unhealthy is it to be near that xray machine? : )
X-ray teardown! wohoo :)
dont tell me you got that xray off ebay
X-Ray machine teardown!
took it from the airport without anybody noticing? :P
If i would have bought a X-ray machine of Ebay and imported it to where i live i would probably had the government all over me.. if it would have even be legal to import that is, which i seriously doubth..
So dam cool though. :)
I was told by someone that biphasic defibrillators do not use inductors to shape the output waveform. Looks like they are wrong, as , (please correct me if i am wrong) , i think your tear down shows an inductor.
x-ray machine, I would so x-ray my head, for Science!
BURN THE MAGNESIUM DOOOO IT. THE WHOLE THING AT ONCE
Too old. The X-ray machines used at the London Olympics were far more advanced.
xray machine made me wtf for a bit
See a doctor.
This is an urgent appeal from the X-Foundation. Right now children around the world are living without access to the most basic amenities. Millions growing up in homes without x-ray machines. We are asking you to donate £10k per week to help children like Jonny. For less than the price of a weekly car purchase, you can help Jonny to see (through things) again. With your help we can end this problem. Thank you.
